* Support "blank" schema when MetaData.schema is setMike Bayer2016-05-182-0/+34
| | | | | | | | | | | | | Previously, it was impossible to have a Table that has None for a schema name when the "schema" parameter on MetaData was set. A new symbol sqlalchemy.schema.BLANK_SCHEMA is added which indicates that the schema name should unconditionally be set to None. In particular, this value must be passed within cross-schema foreign key reflection, so that a Table which is in the "default" schema can be represented properly.

| * Accommodate "callable" bound param in evaluatorMike Bayer2016-05-161-0/+9
| | | | | | | | | | | | | | | | | | | | Fixed bug in "evaluate" strategy of :meth:`.Query.update` and :meth:`.Query.delete` which would fail to accommodate a bound parameter with a "callable" value, as which occurs when filtering by a many-to-one equality expression along a relationship.

* Fix label referencing in SQL Server OFFSET logicMike Bayer2016-05-101-0/+9
| | | | | | | | | | Fixed bug where by ROW_NUMBER OVER clause applied for OFFSET selects in SQL Server would inappropriately substitute a plain column from the local statement that overlaps with a label name used by the ORDER BY criteria of the statement.

* Don't double-process ResultMetaData for BufferedColumnResultProxyMike Bayer2016-04-271-0/+11
| | | | | | | | | | | | Fixed a bug in the result proxy used mainly by Oracle when binary and other LOB types are in play, such that when query / statement caching were used, the type-level result processors, notably that required by the binary type itself but also any other processor, would become lost after the first run of the statement due to it being removed from the cached result metadata.

* Simplify directed graph exampleMike Bayer2016-04-261-0/+8
| | | | | | | | | | Changed the "directed graph" example to no longer consider integer identifiers of nodes as significant; the "higher" / "lower" references now allow mutual edges in both directions.

* Fix result set handling for case insensitive dupe colsMike Bayer2016-04-211-0/+10
| | | | | | | | | | | Fixed bug where when using ``case_sensitive=False`` with an :class:`.Engine`, the result set would fail to correctly accomodate for duplicate column names in the result set, causing an error when the statement is executed in 1.0, and preventing the "ambiguous column" exception from functioning in 1.1.

* Deprecate Mapper.order_byMike Bayer2016-04-192-0/+33
| | | | | | | | | | | This is an old parameter no longer relevant to how SQLAlchemy works, once the Query object was introduced. By deprecating it we establish that we aren't supporting non-working use cases and that we encourage applications to move off of the use of this parameter.

* | Propagate hybrid properties / infoMike Bayer2016-04-181-2/+18
| | | | | | | | | | | | | | | | | | | | | | Keystone and others depend on the .property attribute being "mirrored" when a @hybrid_property is linked directly to a mapped attribute. Restore this linkage and also create a defined behavior for the .info dictionary; it is that of the hybrid itself. Add this behavioral change to the migration notes.

* | Honor hybrid property / method docstringsMike Bayer2016-04-182-0/+58
| | | | | | | | | | | | | | | | | | | | | | | | The docstring specified on a hybrid property or method is now honored at the class level, allowing it to work with tools like Sphinx autodoc. The mechanics here necessarily involve some wrapping of expressions to occur for hybrid properties, which may cause them to appear differently using introspection.

| | | | | | | | | passed to :func:`.column_property`, so that if the same attribute is referred to as a column expression twice the names are de-duped, thus avoiding "ambiguous column" errors.

* - reworked the way the "select_wraps_for" expression isMike Bayer2016-02-201-0/+26
| | | | | | | | | | | | | | | | | | | | | | | handled within visit_select(); this attribute was added in the 1.0 series to accommodate the subquery wrapping behavior of SQL Server and Oracle while also working with positional column targeting and no longer relying upon "key fallback" in order to target columns in such a statement. The IBM DB2 third-party dialect also has this use case, but its implementation is using regular expressions to rewrite the textual SELECT only and does not make use of a "wrapped" select at this time. The logic no longer attempts to reconcile proxy set collections as this was not deterministic, and instead assumes that the select() and the wrapper select() match their columns postionally, at least for the column positions they have in common, so it is now very simple and safe. fixes #3657. - as a side effect of #3657 it was also revealed that the strategy of calling upon a ResultProxy._getter was not correctly calling into NoSuchColumnError when an expected column was not present, and instead returned None up to loading.instances() to produce NoneType failures; added a raiseerr argument to _getter() which is called when we aren't expecting None, fixes #3658.
