Changes noted below are specific to version 0.8.
For changes that are in both 0.7 and 0.8, see below
- SQLAlchemy 0.8 now targets Python 2.5 and
above. Python 2.4 is no longer supported.
- [removed] The "sqlalchemy.exceptions"
synonym for "sqlalchemy.exc" is removed
- [removed] The legacy "mutable" system of the
ORM, including the MutableType class as well
as the mutable=True flag on PickleType
and postgresql.ARRAY has been removed.
In-place mutations are detected by the ORM
using the sqlalchemy.ext.mutable extension,
introduced in 0.7. The removal of MutableType
and associated constructs removes a great
deal of complexity from SQLAlchemy's internals.
The approach performed poorly as it would incur
a scan of the full contents of the Session
when in use. [ticket:2442]
- [moved] The InstrumentationManager interface
and the entire related system of alternate
class implementation is now moved out
to sqlalchemy.ext.instrumentation. This is
a seldom used system that adds significant
complexity and overhead to the mechanics of
class instrumentation. The new architecture
allows it to remain unused until
InstrumentationManager is actually imported,
at which point it is bootstrapped into
- [feature] Major rewrite of relationship()
internals now allow join conditions which
include columns pointing to themselves
within composite foreign keys. A new
API for very specialized primaryjoin conditions
is added, allowing conditions based on
SQL functions, CAST, etc. to be handled
by placing the annotation functions
remote() and foreign() inline within the
expression when necessary. Previous recipes
using the semi-private _local_remote_pairs
approach can be upgraded to this new
- [bug] ORM will perform extra effort to determine
that an FK dependency between two tables is
not significant during flush if the tables
are related via joined inheritance and the FK
dependency is not part of the inherit_condition,
saves the user a use_alter directive.
- [feature] New standalone function with_polymorphic()
provides the functionality of query.with_polymorphic()
in a standalone form. It can be applied to any
entity within a query, including as the target
of a join in place of the "of_type()" modifier.
- [feature] The of_type() construct on attributes
now accepts aliased() class constructs as well
as with_polymorphic constructs, and works with
query.join(), any(), has(), and also
eager loaders subqueryload(), joinedload(),
- [feature] Improvements to event listening for
mapped classes allows that unmapped classes
can be specified for instance- and mapper-events.
The established events will be automatically
set up on subclasses of that class when the
propagate=True flag is passed, and the
events will be set up for that class itself
if and when it is ultimately mapped.
- [bug] The instrumentation events class_instrument(),
class_uninstrument(), and attribute_instrument()
will now fire off only for descendant classes
of the class assigned to listen(). Previously,
an event listener would be assigned to listen
for all classes in all cases regardless of the
"target" argument passed. [ticket:2590]
- [bug] with_polymorphic() produces JOINs
in the correct order and with correct inheriting
tables in the case of sending multi-level
subclasses in an arbitrary order or with
intermediary classes missing. [ticket:1900]
- [feature] The "deferred declarative
reflection" system has been moved into the
declarative extension itself, using the
new DeferredReflection class. This
class is now tested with both single
and joined table inheritance use cases.
- [feature] Added new core function "inspect()",
which serves as a generic gateway to
introspection into mappers, objects,
others. The Mapper and InstanceState
objects have been enhanced with a public
API that allows inspection of mapped
attributes, including filters for column-bound
or relationship-bound properties, inspection
of current object state, history of
attributes, etc. [ticket:2208]
- [feature] Calling rollback() within a
session.begin_nested() will now only expire
those objects that had net changes within the
scope of that transaction, that is objects which
were dirty or were modified on a flush. This
allows the typical use case for begin_nested(),
that of altering a small subset of objects, to
leave in place the data from the larger enclosing
set of objects that weren't modified in
that sub-transaction. [ticket:2452]
- [feature] Added utility feature
Both features should be avoided, however.
- [feature] Added support for .info dictionary argument to
column_property(), relationship(), composite().
All MapperProperty classes have an auto-creating .info
dict available overall.
- [feature] Adding/removing None from a mapped collection
now generates attribute events. Previously, a None
append would be ignored in some cases. Related
- [feature] The presence of None in a mapped collection
now raises an error during flush. Previously,
None values in collections would be silently ignored.
- [feature] The Query.update() method is now
more lenient as to the table
being updated. Plain Table objects are better
supported now, and additional a joined-inheritance
subclass may be used with update(); the subclass
table will be the target of the update,
and if the parent table is referenced in the
WHERE clause, the compiler will call upon
UPDATE..FROM syntax as allowed by the dialect
to satisfy the WHERE clause. MySQL's multi-table
update feature is also supported if columns
are specified by object in the "values" dicitionary.
PG's DELETE..USING is also not available
in Core yet.
- [feature] New session events after_transaction_create
allows tracking of new SessionTransaction objects.
If the object is inspected, can be used to determine
when a session first becomes active and when
- [feature] The Query can now load entity/scalar-mixed
"tuple" rows that contain
types which aren't hashable, by setting the flag
"hashable=False" on the corresponding TypeEngine object
in use. Custom types that return unhashable types
(typically lists) can set this flag to False.
- [bug] Improvements to joined/subquery eager
loading dealing with chains of subclass entities
sharing a common base, with no specific "join depth"
provided. Will chain out to
each subclass mapper individually before detecting
a "cycle", rather than considering the base class
to be the source of the "cycle". [ticket:2481]
- [bug] The "passive" flag on Session.is_modified()
no longer has any effect. is_modified() in
all cases looks only at local in-memory
modified flags and will not emit any
SQL or invoke loader callables/initializers.
- [bug] The warning emitted when using
delete-orphan cascade with one-to-many
or many-to-many without single-parent=True
is now an error. The ORM
would fail to function subsequent to this
warning in any case. [ticket:2405]
- [bug] Lazy loads emitted within flush events
such as before_flush(), before_update(),
etc. will now function as they would
within non-event code, regarding consideration
of the PK/FK values used in the lazy-emitted
special flags would be established that
would cause lazy loads to load related items
based on the "previous" value of the
parent PK/FK values specifically when called
upon within a flush; the signal to load
in this way is now localized to where the
unit of work actually needs to load that
way. Note that the UOW does
sometimes load these collections before
the before_update() event is called,
so the usage of "passive_updates" or not
can affect whether or not a collection will
represent the "old" or "new" data, when
accessed within a flush event, based
on when the lazy load was emitted.
The change is backwards incompatible in
the exceedingly small chance that
user event code depended on the old
- [feature] Query now "auto correlates" by
default in the same way as select() does.
Previously, a Query used as a subquery
in another would require the correlate()
method be called explicitly in order to
correlate a table on the inside to the
outside. As always, correlate(None)
disables correlation. [ticket:2179]
- [feature] The after_attach event is now
emitted after the object is established
in Session.new or Session.identity_map
upon Session.add(), Session.merge(),
etc., so that the object is represented
in these collections when the event
is called. Added before_attach
event to accommodate use cases that
need autoflush w pre-attached object.
- [feature] The Session will produce warnings
when unsupported methods are used inside the
"execute" portion of the flush. These are
the familiar methods add(), delete(), etc.
as well as collection and related-object
manipulations, as called within mapper-level
like after_insert(), after_update(), etc.
It's been prominently documented for a long
time that SQLAlchemy cannot guarantee
results when the Session is manipulated within
the execution of the flush plan,
however users are still doing it, so now
there's a warning. Maybe someday the Session
will be enhanced to support these operations
inside of the flush, but for now, results
can't be guaranteed.
- [bug] Continuing [ticket:2566] regarding extra
state post-flush due to event listeners;
any states that are marked as "dirty" from an
attribute perspective, usually via column-attribute
set events within after_insert(), after_update(),
etc., will get the "history" flag reset
in all cases, instead of only those instances
that were part of the flush. This has the effect
that this "dirty" state doesn't carry over
after the flush and won't result in UPDATE
statements. A warning is emitted to this
effect; the set_committed_state()
method can be used to assign attributes on objects
without producing history events. [ticket:2582]
- [feature] ORM entities can be passed
to the core select() construct as well
as to the select_from(),
correlate(), and correlate_except()
methods of select(), where they will be unwrapped
into selectables. [ticket:2245]
- [feature] Some support for auto-rendering of a
relationship join condition based on the mapped
attribute, with usage of core SQL constructs.
would render SELECT from "someclass" and use the
primaryjoin of "somerelationship" as the WHERE
clause. This changes the previous meaning
of "SomeClass.somerelationship" when used in a
core SQL context; previously, it would "resolve"
to the parent selectable, which wasn't generally
useful. Also works with query.filter().
Related to [ticket:2245].
- [feature] The registry of classes
in declarative_base() is now a
WeakValueDictionary. So subclasses of
"Base" that are dereferenced will be
garbage collected, *if they are not
referred to by any other mappers/superclass
mappers*. See the next note for this ticket.
- [feature] Conflicts between columns on
single-inheritance declarative subclasses,
with or without using a mixin, can be resolved
using a new @declared_attr usage described
in the documentation. [ticket:2472]
- [feature] declared_attr can now be used
on non-mixin classes, even though this is generally
only useful for single-inheritance subclass
column conflict resolution. [ticket:2472]
- [feature] declared_attr can now be used with
attributes that are not Column or MapperProperty;
including any user-defined value as well
as association proxy objects. [ticket:2517]
- [bug] Fixed a disconnect that slowly evolved
between a @declared_attr Column and a
directly-defined Column on a mixin. In both
cases, the Column will be applied to the
declared class' table, but not to that of a
joined inheritance subclass. Previously,
the directly-defined Column would be placed
on both the base and the sub table, which isn't
typically what's desired. [ticket:2565]
- [feature] *Very limited* support for
inheriting mappers to be GC'ed when the
class itself is deferenced. The mapper
must not have its own table (i.e.
single table inh only) without polymorphic
attributes in place.
This allows for the use case of
creating a temporary subclass of a declarative
mapped class, with no table or mapping
directives of its own, to be garbage collected
when dereferenced by a unit test.
- [feature] Declarative now maintains a registry
of classes by string name as well as by full
module-qualified name. Multiple classes with the
same name can now be looked up based on a module-qualified
string within relationship(). Simple class name
lookups where more than one class shares the same
name now raises an informative error message.
- [feature] Can now provide class-bound attributes
that override columns which are of any
non-ORM type, not just descriptors.
- [feature] Added with_labels and
reduce_columns keyword arguments to
Query.subquery(), to provide two alternate
strategies for producing queries with uniquely-
named columns. [ticket:1729].
- [feature] A warning is emitted when a reference
to an instrumented collection is no longer
associated with the parent class due to
replacement, but an append
or remove operation is received on the
now-detached collection. [ticket:2476]
- [bug] Declarative can now propagate a column
declared on a single-table inheritance subclass
up to the parent class' table, when the parent
class is itself mapped to a join() or select()
statement, directly or via joined inheritance,
and not just a Table. [ticket:2549]
- [bug] An error is emitted when uselist=False
is combined with a "dynamic" loader.
This is a warning in 0.7.9.
- [removed] Deprecated identifiers removed:
* allow_null_pks mapper() argument
* _get_col_to_prop() mapper method
* dont_load argument to Session.merge()
* sqlalchemy.orm.shard module
- [feature] Connection event listeners can
now be associated with individual
Connection objects, not just Engine
- [feature] The before_cursor_execute event
fires off for so-called "_cursor_execute"
events, which are usually special-case
executions of primary-key bound sequences
and default-generation SQL
phrases that invoke separately when RETURNING
is not used with INSERT. [ticket:2459]
- [feature] The libraries used by the test suite
have been moved around a bit so that they are
part of the SQLAlchemy install again. In addition,
a new suite of tests is present in the
new sqlalchemy.testing.suite package. This is
an under-development system that hopes to provide
a universal testing suite for external dialects.
Dialects which are maintained outside of SQLAlchemy
can use the new test fixture as the framework
for their own tests, and will get for free a
"compliance" suite of dialect-focused tests,
including an improved "requirements" system
where specific capabilities and features can
be enabled or disabled for testing.
- [bug] The Inspector.get_table_names()
order_by="foreign_key" feature now sorts
tables by dependee first, to be consistent
with util.sort_tables and metadata.sorted_tables.
- [bug] Fixed bug whereby if a database restart
affected multiple connections, each
connection would individually invoke a new
disposal of the pool, even though only
one disposal is needed. [ticket:2522]
- [feature] Added a new system
for registration of new dialects in-process
without using an entrypoint. See the
docs for "Registering New Dialects".
- [feature] The "required" flag is set to
True by default, if not passed explicitly,
on bindparam() if the "value" or "callable"
parameters are not passed.
This will cause statement execution to check
for the parameter being present in the final
collection of bound parameters, rather than
implicitly assigning None. [ticket:2556]
- [feature] Various API tweaks to the "dialect"
API to better support highly specialized
systems such as the Akiban database, including
more hooks to allow an execution context to
access type processors.
- [bug] The names of the columns on the
.c. attribute of a select().apply_labels()
is now based on <tablename>_<colkey> instead
of <tablename>_<colname>, for those columns
that have a distinctly named .key.
- [feature] Inspector.get_primary_keys() is
deprecated; use Inspector.get_pk_constraint().
Courtesy Diana Clarke. [ticket:2422]
- [bug] The autoload_replace flag on Table,
when False, will cause any reflected foreign key
constraints which refer to already-declared
columns to be skipped, assuming that the
in-Python declared column will take over
the task of specifying in-Python ForeignKey
or ForeignKeyConstraint declarations.
- [bug] The ResultProxy methods inserted_primary_key,
postfetch_cols(), prefetch_cols() all
assert that the given statement is a compiled
construct, and is an insert() or update()
statement as is appropriate, else
raise InvalidRequestError. [ticket:2498]
- [feature] New C extension module "utils" has
been added for additional function speedups
as we have time to implement.
- ResultProxy.last_inserted_ids is removed,
replaced by inserted_primary_key.
- [feature] Major rework of operator system
in Core, to allow redefinition of existing
operators as well as addition of new operators
at the type level. New types can be created
from existing ones which add or redefine
operations that are exported out to column
expressions, in a similar manner to how the
ORM has allowed comparator_factory. The new
architecture moves this capability into the
Core so that it is consistently usable in
all cases, propagating cleanly using existing
type propagation behavior. [ticket:2547]
- [feature] To complement [ticket:2547], types
can now provide "bind expressions" and
"column expressions" which allow compile-time
injection of SQL expressions into statements
on a per-column or per-bind level. This is
to suit the use case of a type which needs
to augment bind- and result- behavior at the
SQL level, as opposed to in the Python level.
Allows for schemes like transparent encryption/
decryption, usage of Postgis functions, etc.
- [feature] The Core oeprator system now includes
the `getitem` operator, i.e. the bracket
operator in Python. This is used at first
to provide index and slice behavior to the
Postgresql ARRAY type, and also provides a hook
for end-user definition of custom __getitem__
schemes which can be applied at the type
level as well as within ORM-level custom
operator schemes. `lshift` (<<)
and `rshift` (>>) are also supported as
Note that this change has the effect that
descriptor-based __getitem__ schemes used by
the ORM in conjunction with synonym() or other
"descriptor-wrapped" schemes will need
to start using a custom comparator in order
to maintain this behavior.
- [feature] Revised the rules used to determine
the operator precedence for the user-defined
operator, i.e. that granted using the ``op()``
method. Previously, the smallest precedence
was applied in all cases, now the default
precedence is zero, lower than all operators
except "comma" (such as, used in the argument
list of a ``func`` call) and "AS", and is
also customizable via the "precedence" argument
on the ``op()`` method. [ticket:2537]
- [feature] Added "collation" parameter to all
String types. When present, renders as
COLLATE <collation>. This to support the
COLLATE keyword now supported by several
databases including MySQL, SQLite, and Postgresql.
- [change] The Text() type renders the length
given to it, if a length was specified.
- [feature] Custom unary operators can now be
used by combining operators.custom_op() with
- [bug] A tweak to column precedence which moves the
"concat" and "match" operators to be the same as
that of "is", "like", and others; this helps with
parenthesization rendering when used in conjunction
with "IS". [ticket:2564]
- [feature] Enhanced GenericFunction and func.*
to allow for user-defined GenericFunction
subclasses to be available via the func.*
namespace automatically by classname,
optionally using a package name, as well
as with the ability to have the rendered
name different from the identified name
- [feature] The cast() and extract() constructs
will now be produced via the func.* accessor
as well, as users naturally try to access these
names from func.* they might as well do
what's expected, even though the returned
object is not a FunctionElement.
- [changed] Most classes in expression.sql
are no longer preceded with an underscore,
i.e. Label, SelectBase, Generative, CompareMixin.
_BindParamClause is also renamed to
BindParameter. The old underscore names for
these classes will remain available as synonyms
for the foreseeable future.
- [feature] The Inspector object can now be
acquired using the new inspect() service,
part of [ticket:2208]
- [feature] The column_reflect event now
accepts the Inspector object as the first
argument, preceding "table". Code which
uses the 0.7 version of this very new
event will need modification to add the
"inspector" object as the first argument.
- [feature] The behavior of column targeting
in result sets is now case sensitive by
default. SQLAlchemy for many years would
run a case-insensitive conversion on these values,
probably to alleviate early case sensitivity
issues with dialects like Oracle and
Firebird. These issues have been more cleanly
solved in more modern versions so the performance
hit of calling lower() on identifiers is removed.
The case insensitive comparisons can be re-enabled
by setting "case_insensitive=False" on
- [bug] Applying a column expression to a select
statement using a label with or without other
modifying constructs will no longer "target" that
expression to the underlying Column; this affects
ORM operations that rely upon Column targeting
in order to retrieve results. That is, a query
like query(User.id, User.id.label('foo')) will now
track the value of each "User.id" expression separately
instead of munging them together. It is not expected
that any users will be impacted by this; however,
a usage that uses select() in conjunction with
query.from_statement() and attempts to load fully
composed ORM entities may not function as expected
if the select() named Column objects with arbitrary
.label() names, as these will no longer target to
the Column objects mapped by that entity.
- [feature] The "unconsumed column names" warning emitted
when keys are present in insert.values() or update.values()
that aren't in the target table is now an exception.
- [feature] Added "MATCH" clause to ForeignKey,
ForeignKeyConstraint, courtesy Ryan Kelly.
- [feature] Added support for DELETE and UPDATE from
an alias of a table, which would assumedly
be related to itself elsewhere in the query,
courtesy Ryan Kelly. [ticket:2507]
- [feature] select() features a correlate_except()
method, auto correlates all selectables except those
- [feature] The prefix_with() method is now available
on each of select(), insert(), update(), delete(),
all with the same API, accepting multiple
prefix calls, as well as a "dialect name" so that
the prefix can be limited to one kind of dialect.
- [feature] Added reduce_columns() method
to select() construct, replaces columns inline
using the util.reduce_columns utility function
to remove equivalent columns. reduce_columns()
also adds "with_only_synonyms" to limit the
reduction just to those columns which have the same
name. The deprecated fold_equivalents() feature is
- [feature] Reworked the startswith(), endswith(),
contains() operators to do a better job with
negation (NOT LIKE), and also to assemble them
at compilation time so that their rendered SQL
can be altered, such as in the case for Firebird
STARTING WITH [ticket:2470]
- [feature] Added a hook to the system of rendering
CREATE TABLE that provides access to the render for each
Column individually, by constructing a @compiles
function against the new schema.CreateColumn
- [feature] "scalar" selects now have a WHERE method
to help with generative building. Also slight adjustment
regarding how SS "correlates" columns; the new methodology
no longer applies meaning to the underlying
Table column being selected. This improves
some fairly esoteric situations, and the logic
that was there didn't seem to have any purpose.
- [bug] Fixes to the interpretation of the
Column "default" parameter as a callable
to not pass ExecutionContext into a keyword
argument parameter. [ticket:2520]
- [bug] All of UniqueConstraint, ForeignKeyConstraint,
CheckConstraint, and PrimaryKeyConstraint will
attach themselves to their parent table automatically
when they refer to a Table-bound Column object directly
(i.e. not just string column name), and refer to
one and only one Table. Prior to 0.8 this behavior
occurred for UniqueConstraint and PrimaryKeyConstraint,
but not ForeignKeyConstraint or CheckConstraint.
- [bug] TypeDecorator now includes a generic repr()
that works in terms of the "impl" type by default.
This is a behavioral change for those TypeDecorator
classes that specify a custom __init__ method; those
types will need to re-define __repr__() if they need
__repr__() to provide a faithful constructor representation.
- [bug] column.label(None) now produces an
anonymous label, instead of returning the
column object itself, consistent with the behavior
of label(column, None). [ticket:2168]
- [feature] An explicit error is raised when
a ForeignKeyConstraint() that was
constructed to refer to multiple remote tables
is first used. [ticket:2455]
- [feature] the MS Access dialect has been
moved to its own project on Bitbucket,
taking advantage of the new SQLAlchemy
dialect compliance suite. The dialect is
still in very rough shape and probably not
ready for general use yet, however
it does have *extremely* rudimental
- [moved] The MaxDB dialect, which hasn't been
functional for several years, is
moved out to a pending bitbucket project,
- [feature] the SQLite date and time types
have been overhauled to support a more open
ended format for input and output, using
name based format strings and regexps. A
new argument "microseconds" also provides
the option to omit the "microseconds"
portion of timestamps. Thanks to
Nathan Wright for the work and tests on
- [feature] SQL Server dialect can be given
database-qualified schema names,
i.e. "schema='mydatabase.dbo'"; reflection
operations will detect this, split the schema
among the "." to get the owner separately,
and emit a "USE mydatabase" statement before
reflecting targets within the "dbo" owner;
the existing database returned from
DB_NAME() is then restored.
- [bug] removed legacy behavior whereby
a column comparison to a scalar SELECT via
== would coerce to an IN with the SQL server
dialect. This is implicit
behavior which fails in other scenarios
so is removed. Code which relies on this
needs to be modified to use column.in_(select)
- [feature] updated support for the mxodbc
driver; mxodbc 3.2.1 is recommended for full
- [feature] postgresql.ARRAY features an optional
"dimension" argument, will assign a specific
number of dimensions to the array which will
render in DDL as ARRAY..., also improves
performance of bind/result processing.
- [feature] postgresql.ARRAY now supports
indexing and slicing. The Python  operator
is available on all SQL expressions that are
of type ARRAY; integer or simple slices can be
passed. The slices can also be used on the
assignment side in the SET clause of an UPDATE
statement by passing them into Update.values();
see the docs for examples.
- [feature] Added new "array literal" construct
postgresql.array(). Basically a "tuple" that
renders as ARRAY[1,2,3].
- [feature] Added support for the Postgresql ONLY
keyword, which can appear corresponding to a
table in a SELECT, UPDATE, or DELETE statement.
The phrase is established using with_hint().
Courtesy Ryan Kelly [ticket:2506]
- [feature] The "ischema_names" dictionary of the
Postgresql dialect is "unofficially" customizable.
Meaning, new types such as PostGIS types can
be added into this dictionary, and the PG type
reflection code should be able to handle simple
types with variable numbers of arguments.
The functionality here is "unofficial" for
1. this is not an "official" API. Ideally
an "official" API would allow custom type-handling
callables at the dialect or global level
in a generic way.
2. This is only implemented for the PG dialect,
in particular because PG has broad support
for custom types vs. other database backends.
A real API would be implemented at the
default dialect level.
3. The reflection code here is only tested against
simple types and probably has issues with more
patch courtesy Éric Lemoine.
- [feature] The "startswith()" operator renders
as "STARTING WITH", "~startswith()" renders
as "NOT STARTING WITH", using FB's more efficient
- [bug] CompileError is raised when VARCHAR with
no length is attempted to be emitted, same
way as MySQL. [ticket:2505]
- [bug] Firebird now uses strict "ansi bind rules"
so that bound parameters don't render in the
columns clause of a statement - they render
- [bug] Support for passing datetime as date when
using the DateTime type with Firebird; other
dialects support this.
- [feature] An experimental dialect for the fdb
driver is added, but is untested as I cannot
get the fdb package to build. [ticket:2504]
- [bug] Dialect no longer emits expensive server
collations query, as well as server casing,
on first connect. These functions are still
available as semi-private. [ticket:2404]
- [feature] Added TIME type to mysql dialect,
accepts "fst" argument which is the new
"fractional seconds" specifier for recent
MySQL versions. The datatype will interpret
a microseconds portion received from the driver,
however note that at this time most/all MySQL
DBAPIs do not support returning this value.
- [bug] Quoting information is now passed along
from a Column with quote=True when generating
a same-named bound parameter to the bindparam()
object, as is the case in generated INSERT and UPDATE
statements, so that unknown reserved names can
be fully supported. [ticket:2437]
- [feature] The types of columns excluded from the
setinputsizes() set can be customized by sending
a list of string DBAPI type names to exclude,
using the exclude_setinputsizes dialect parameter.
This list was previously fixed. The list also
now defaults to STRING, UNICODE, removing
CLOB, NCLOB from the list. [ticket:2561]
- [bug] The CreateIndex construct in Oracle
will now schema-qualify the name of the index
to be that of the parent table. Previously this
name was omitted which apparently creates the
index in the default schema, rather than that
of the table.
- [removed] The SQLSoup extension is removed from
SQLAlchemy, and is now an external project.
