Fetch first support

2020-10-02T19:34:24+00:00

Add support to ``FETCH {FIRST | NEXT} [ count ] {ROW | ROWS}
 {ONLY | WITH TIES}`` in the select for the supported backends,
currently PostgreSQL, Oracle and MSSQL.

raise on lower-case column shared to multiple tables

2020-09-30T13:37:02+00:00

Fixed bug where an error was not raised for lower-case
:func:`_column` added to lower-case :func:`_table` object. This now raises
:class:`_exc.ArgumentError` which has always been the case for
upper-case :class:`_schema.Column` and :class:`_schema.Table`.

Scan for tables without relying upon whereclause

2020-09-29T20:46:56+00:00

Fixed bug where an UPDATE statement against a JOIN using MySQL multi-table
format would fail to include the table prefix for the target table if the
statement had no WHERE clause, as only the WHERE clause were scanned to
detect a "multi table update" at that particular point.  The target
is now also scanned if it's a JOIN to get the leftmost table as the
primary table and the additional entries as additional FROM entries.

Add reflection for Identity columns

2020-09-28T22:11:12+00:00

Added support for reflecting "identity" columns, which are now returned
as part of the structure returned by :meth:`_reflection.Inspector.get_columns`.
When reflecting full :class:`_schema.Table` objects, identity columns will
be represented using the :class:`_schema.Identity` construct.

Fixed compilation error on oracle for sequence and identity column
``nominvalue`` and ``nomaxvalue`` options that require no space in them.

Improved test compatibility with oracle 18.

As part of the support for reflecting :class:`_schema.Identity` objects,
the method :meth:`_reflection.Inspector.get_columns` no longer returns
``mssql_identity_start`` and ``mssql_identity_increment`` as part of the
``dialect_options``. Use the information in the ``identity`` key instead.

The mssql dialect will assume that at least MSSQL 2005 is used.
There is no hard exception raised if a previous version is detected,
but operations may fail for older versions.

Add deprecation warning for .join().alias()

2020-09-28T16:08:04+00:00

The :meth:`_sql.Join.alias` method is deprecated and will be removed in
SQLAlchemy 2.0.   An explicit select + subquery, or aliasing of the inner
tables, should be used instead.

Accommodate for same base class multiple times in inherits list

2020-09-27T15:45:49+00:00

Improved declarative inheritance scanning to not get tripped up when the
same base class appears multiple times in the base inheritance list.
