* - Added :paramref:`.MetaData.reflect.**dialect_kwargs`Mike Bayer2014-02-021-38/+149
| | | | | | | | | | | | | | | | | | to support dialect-level reflection options for all :class:`.Table` objects reflected. - Added a new dialect-level argument ``postgresql_ignore_search_path``; this argument is accepted by both the :class:`.Table` constructor as well as by the :meth:`.MetaData.reflect` method. When in use against Postgresql, a foreign-key referenced table which specifies a remote schema name will retain that schema name even if the name is present in the ``search_path``; the default behavior since 0.7.3 has been that schemas present in ``search_path`` would not be copied to reflected :class:`.ForeignKey` objects. The documentation has been updated to describe in detail the behavior of the ``pg_get_constraintdef()`` function and how the ``postgresql_ignore_search_path`` feature essentially determines if we will honor the schema qualification reported by this function or not.

* | - The typing system now handles the task of rendering "literal bind" values,Mike Bayer2013-10-201-9/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | e.g. values that are normally bound parameters but due to context must be rendered as strings, typically within DDL constructs such as CHECK constraints and indexes (note that "literal bind" values become used by DDL as of :ticket:`2742`). A new method :meth:`.TypeEngine.literal_processor` serves as the base, and :meth:`.TypeDecorator.process_literal_param` is added to allow wrapping of a native literal rendering method. [ticket:2838] - enhance _get_colparams so that we can send flags like literal_binds into INSERT statements - add support in PG for inspecting standard_conforming_strings - add a new series of roundtrip tests based on INSERT of literal plus SELECT for basic literal rendering in dialect suite

* - A rework to the way that "quoted" identifiers are handled, in thatMike Bayer2013-08-271-4/+4
| | | | | | | | | | | | | | | | 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]

* 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.
