* - Turned off the "simple order by" flag on the MSSQL dialect; thisMike Bayer2015-03-241-0/+1
| | | | | | | | | | | is the flag that per :ticket:`2992` causes an order by or group by an expression that's also in the columns clause to be copied by label, even if referenced as the expression object. The behavior for MSSQL is now the old behavior that copies the whole expression in by default, as MSSQL can be picky on these particularly in GROUP BY expressions. fixes #3338 - Add a test that includes a composed label in a GROUP BY

* - the change for #918 was of course not nearly that simple.Mike Bayer2015-03-071-1/+2
| | | | | | | | | | | | | | | | | | The "wrapping" employed by the mssql and oracle dialects using the "iswrapper" argument was not being used intelligently by the compiler, and the result map was being written incorrectly, using *more* columns in the result map than were actually returned by the statement, due to "row number" columns that are inside the subquery. The compiler now writes out result map on the "top level" select in all cases fully, and for the mssql/oracle wrapping case extracts out the "proxied" columns in a second step, which only includes those columns that are proxied outwards to the top level. This change might have implications for 3rd party dialects that might be imitating oracle's approach. They can safely continue to use the "iswrapper" kw which is now ignored, but they may need to also add the _select_wraps argument as well.
* - Custom dialects that implement :class:`.GenericTypeCompiler` canMike Bayer2015-01-161-40/+42
| | | | | | | | | | | | | | now be constructed such that the visit methods receive an indication of the owning expression object, if any. Any visit method that accepts keyword arguments (e.g. ``**kw``) will in most cases receive a keyword argument ``type_expression``, referring to the expression object that the type is contained within. For columns in DDL, the dialect's compiler class may need to alter its ``get_column_specification()`` method to support this as well. The ``UserDefinedType.get_col_spec()`` method will also receive ``type_expression`` if it provides ``**kw`` in its argument signature. fixes #3074
* - SQL Server 2012 now recommends VARCHAR(max), NVARCHAR(max),Mike Bayer2014-12-061-9/+96
| | | | | | | VARBINARY(max) for large text/binary types. The MSSQL dialect will now respect this based on version detection, as well as the new ``deprecate_large_types`` flag. fixes #3039

| | | | | | | | pyodbc will no longer specify a default "driver name", and a warning is emitted if this is missing. The optimal driver name for SQL Server changes frequently and is per-platform, so hostname based connections need to specify this. DSN-based connections are preferred. fixes #3182

| | | | | | | query used to determine "default schema" is invalid in SQL Server 2000. For SQL Server 2000 we go back to defaulting to the "schema name" parameter of the dialect, which is configurable but defaults to 'dbo'. fixes #3025
* - Added statement encoding to the "SET IDENTITY_INSERT"Mike Bayer2014-07-141-6/+12
| | | | | | | | | statements which operate when an explicit INSERT is being interjected into an IDENTITY column, to support non-ascii table identifiers on drivers such as pyodbc + unix + py2k that don't support unicode statements. ref #3091 as this fix is also in that issue's patch, but is a different issue.

* - A rework to the way that "quoted" identifiers are handled, in thatMike Bayer2013-08-271-2/+2
| | | | | | | | | | | | | | | | instead of relying upon various ``quote=True`` flags being passed around, these flags are converted into rich string objects with quoting information included at the point at which they are passed to common schema constructs like :class:`.Table`, :class:`.Column`, etc. This solves the issue of various methods that don't correctly honor the "quote" flag such as :meth:`.Engine.has_table` and related methods. The :class:`.quoted_name` object is a string subclass that can also be used explicitly if needed; the object will hold onto the quoting preferences passed and will also bypass the "name normalization" performed by dialects that standardize on uppercase symbols, such as Oracle, Firebird and DB2. The upshot is that the "uppercase" backends can now work with force-quoted names, such as lowercase-quoted names and new reserved words. [ticket:2812]

| | | | | | | | | | | | | - Part of a longer series of fixes needed for pyodbc+ mssql, a CAST to NVARCHAR(max) has been added to the bound parameter for the table name and schema name in all information schema queries to avoid the issue of comparing NVARCHAR to NTEXT, which seems to be rejected by the ODBC driver in some cases, such as FreeTDS (0.91 only?) plus unicode bound parameters being passed. The issue seems to be specific to the SQL Server information schema tables and the workaround is harmless for those cases where the problem doesn't exist in the first place. [ticket:2355]
