* - Fixed issue where a primary key column that has a Sequence on it,Mike Bayer2013-12-201-1/+7
| | | | | | | | | yet the column is not the "auto increment" column, either because it has a foreign key constraint or ``autoincrement=False`` set, would attempt to fire the Sequence on INSERT for backends that don't support sequences, when presented with an INSERT missing the primary key value. This would take place on non-sequence backends like SQLite, MySQL. [ticket:2896]
* - Fixed bug with :meth:`.Insert.from_select` method where the orderMike Bayer2013-12-192-5/+20
| | | | | | | | of the given names would not be taken into account when generating the INSERT statement, thus producing a mismatch versus the column names in the given SELECT statement. Also noted that :meth:`.Insert.from_select` implies that Python-side insert defaults cannot be used, since the statement has no VALUES clause. [ticket:2895]
* - for [ticket:2651], leaving CheckConstraint alone, preferring to keepMike Bayer2013-12-161-2/+3
| | | | | | | | | | | | backwards compatibility. A note about backslashing escapes is added. Because the Text() construct now supports bind params better, the example given in the code raises an exception now, so that should cover us. The exception itself has been enhanced to include the key name of the bound param. We're backporting this to 0.8 but 0.8 doesn't have the text->bind behavior that raises.

* Fixed bug where the expression system relied upon the ``str()``Mike Bayer2013-07-123-5/+23
| | | | | | | | | | | | form of a some expressions when referring to the ``.c`` collection on a ``select()`` construct, but the ``str()`` form isn't available since the element relies on dialect-specific compilation constructs, notably the ``__getitem__()`` operator as used with a Postgresql ``ARRAY`` element. The fix also adds a new exception class :class:`.UnsupportedCompilationError` which is raised in those cases where a compiler is asked to compile something it doesn't know how to. [ticket:2780]
* - Added new method to the :func:`.insert` constructMike Bayer2013-07-052-3/+52
| | | | | | | | | | :meth:`.Insert.from_select`. Given a list of columns and a selectable, renders ``INSERT INTO (table) (columns) SELECT ..``. While this feature is highlighted as part of 0.9 it is also backported to 0.8.3. [ticket:722] - The :func:`.update`, :func:`.insert`, and :func:`.delete` constructs will now interpret ORM entities as FROM clauses to be operated upon, in the same way that select() already does.
* Fixed bug when using multi-table UPDATE where a supplementalMike Bayer2013-07-021-2/+2
| | | | | | | table is a SELECT with its own bound parameters, where the positioning of the bound parameters would be reversed versus the statement itself when using MySQL's special syntax. [ticket:2768]
* - rework of correlation, continuing on #2668, #2746Mike Bayer2013-06-262-65/+189
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - add support for correlations to propagate all the way in; because correlations require context now, need to make sure a select enclosure of any level takes effect any number of levels deep. - fix what we said correlate_except() was supposed to do when we first released #2668 - "the FROM clause is left intact if the correlated SELECT is not used in the context of an enclosing SELECT..." - it was not considering the "existing_froms" collection at all, and prohibited additional FROMs from being placed in an any() or has(). - add test for multilevel any() - lots of docs, including glossary entries as we really need to define "WHERE clause", "columns clause" etc. so that we can explain correlation better - based on the insight that a SELECT can correlate anything that ultimately came from an enclosing SELECT that links to this one via WHERE/columns/HAVING/ORDER BY, have the compiler keep track of the FROM lists that correspond in this way, link it to the asfrom flag, so that we send to _get_display_froms() the exact list of candidate FROMs to correlate. no longer need any asfrom logic in the Select() itself - preserve 0.8.1's behavior for correlation when no correlate options are given, not to mention 0.7 and prior's behavior of not propagating implicit correlation more than one level.. this is to reduce surprises/hard-to-debug situations when a user isn't trying to correlate anything.

| | | | | | | | | | | | called :attr:`.TypeDecorator.coerce_to_is_types`, to make it easier to control how comparisons using ``==`` or ``!=`` to ``None`` and boolean types goes about producing an ``IS`` expression, or a plain equality expression with a bound parameter.

* Fully implemented the IS and IS NOT operators withMike Bayer2013-04-221-12/+34
| | | | | | | | | | regards to the True/False constants. An expression like ``col.is_(True)`` will now render ``col IS true`` on the target platform, rather than converting the True/ False constant to an integer bound parameter. This allows the ``is_()`` operator to work on MySQL when given True/False constants. [ticket:2682]
* A major fix to the way in which a select() object producesMike Bayer2013-04-112-22/+58
| | | | | | | | | | | | | | | | | | | labeled columns when apply_labels() is used; this mode produces a SELECT where each column is labeled as in <tablename>_<columnname>, to remove column name collisions for a multiple table select. The fix is that if two labels collide when combined with the table name, i.e. "foo.bar_id" and "foo_bar.id", anonymous aliasing will be applied to one of the dupes. This allows the ORM to handle both columns independently; previously, 0.7 would in some cases silently emit a second SELECT for the column that was "duped", and in 0.8 an ambiguous column error would be emitted. The "keys" applied to the .c. collection of the select() will also be deduped, so that the "column being replaced" warning will no longer emit for any select() that specifies use_labels, though the dupe key will be given an anonymous label which isn't generally user-friendly. [ticket:2702]
