* Add basic support of unique constraints reflectionpr/4Roman Podolyaka2013-06-091-0/+30
| | | | | | | | | | | | Inspection API already supports reflection of table indexes information and those also include unique constraints (at least for PostgreSQL and MySQL). But it could be actually useful to distinguish between indexes and plain unique constraints (though both are implemented in the same way internally in RDBMS). This change adds a new method to Inspection API - get_unique_constraints() and implements it for SQLite, PostgreSQL and MySQL dialects.

If this occurs with a non list/tuple type, the error message is now informative and directs to specify a dimension for the ARRAY. [ticket:2681]

* compiler: add support for multirow insertsIdan Kamara2012-12-061-0/+1
| | | | | | | | | | | | | | | | | | | | | Some databases support this syntax for inserts: INSERT INTO table (id, name) VALUES ('v1', 'v2'), ('v3', 'v4'); which greatly increases INSERT speed. It is now possible to pass a list of lists/tuples/dictionaries as the values param to the Insert construct. We convert it to a flat dictionary so we can continue using bind params. The above query will be converted to: INSERT INTO table (id, name) VALUES (:id, :name), (:id0, :name0); Currently only supported on postgresql, mysql and sqlite.

* - move out maxdbMike Bayer2012-10-181-2/+12
| | | | | | - begin consolidating docs for dialects to be more self contained - add a separate section for "external" dialects - not sure how we're going to go with this yet.

* - [feature] The Core oeprator system now includesMike Bayer2012-08-201-9/+151
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. 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] 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] To complement [ticket:2547], typesMike Bayer2012-08-171-4/+1
| | | | | | | | | | | | | | | | 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. [ticket:1534] - update postgis example fully. - still need to repair the result map propagation here to be transparent for cases like "labeled column".
* _adapt_expression() moves fully to _DefaultColumnComparator which resumesMike Bayer2012-08-161-3/+4
| | | | | | its original role as stateful, forms the basis of TypeEngine.Comparator. lots of code goes back mostly as it was just with cleaner typing behavior, such as simple flow in _binary_operate now.
* - fix concat() operator, testsMike Bayer2012-08-141-3/+3
| | | | | | | | - [feature] Custom unary operators can now be used by combining operators.custom_op() with UnaryExpression(). - clean up the operator dispatch system and make it more consistent. This does change the compiler contract for custom ops.

* - [feature] Revised the rules used to determineMike Bayer2012-07-221-101/+102
| | | | | | | | | | | | 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 "MATCH" clause to ForeignKey,Mike Bayer2012-06-211-0/+23
| | | | | | | | | | | | | | ForeignKeyConstraint, courtesy Ryan Kelly. [ticket:2502] - [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] 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]

|\ | | | | | | | | | | | | | | deprecated; use Inspector.get_pk_constraint(). Courtesy Diana Clarke. [ticket:2422] - restored default get_primary_keys()/get_pk_constraint() wrapper to help maintain compatibility with third party dialects created against 0.6 or 0.7

* | - [removed] The legacy "mutable" system of theMike Bayer2012-04-231-34/+3
|/ | | | | | | | | | | | | | 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]
