* Changed pg8000 dialect to cope with native JSONpr/132Tony Locke2015-01-031-1/+12
| | | | | For versions > 1.10.1 pg8000 returns de-serialized JSON objects rather than a string. SQL parameters are still strings though.
* Make pg8000 version detection more robustTony Locke2014-12-161-6/+11
| | | | | | pg8000 uses Versioneer, which means that development versions have version strings that don't fit into the dotted triple number format. Released versions will always fit the triple format though.
* pg8000 client_encoding in create_engine()Tony Locke2014-12-162-10/+60
| | | | | The pg8000 dialect now supports the setting of the PostgreSQL parameter client_encoding from create_engine().

| | | | | | | | | | to :meth:`.Session.close`, except also calls :meth:`.Connection.invalidate` on all connections, guaranteeing that they will not be returned to the connection pool. This is useful in situations e.g. dealing with gevent timeouts when it is not safe to use the connection further, even for rollbacks. references #3258

| | | | | | | | | | | | | | | | | | | | | | | | :class:`.sqlite.TIME`, or :class:`.sqlite.DATETIME` types, and given a ``storage_format`` that only renders numbers, will render the types in DDL as ``DATE_CHAR``, ``TIME_CHAR``, and ``DATETIME_CHAR``, so that despite the lack of alpha characters in the values, the column will still deliver the "text affinity". Normally this is not needed, as the textual values within the default storage formats already imply text. fixes #3257

| * - the refactor of the visit_alias() method in Oracle revealedMike Bayer2014-12-042-1/+8
| | | | | | | | that quoting should be applied in %(name)s under with_hint.
| * - Added support for CTEs under Oracle. This includes some tweaksMike Bayer2014-12-049-61/+247
| | | | | | | | | | | | | | to the aliasing syntax, as well as a new CTE feature :meth:`.CTE.suffix_with`, which is useful for adding in special Oracle-specific directives to the CTE. fixes #3220
| * - Updated the "supports_unicode_statements" flag to True for MySQLdbMike Bayer2014-12-043-3/+13
| | | | | | | | | | | | | | | | | | and Pymysql under Python 2. This refers to the SQL statements themselves, not the parameters, and affects issues such as table and column names using non-ASCII characters. These drivers both appear to support Python 2 Unicode objects without issue in modern versions. fixes #3121
| * - The :meth:`.Operators.match` operator is now handled such that theMike Bayer2014-12-0414-16/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | return type is not strictly assumed to be boolean; it now returns a :class:`.Boolean` subclass called :class:`.MatchType`. The type will still produce boolean behavior when used in Python expressions, however the dialect can override its behavior at result time. In the case of MySQL, while the MATCH operator is typically used in a boolean context within an expression, if one actually queries for the value of a match expression, a floating point value is returned; this value is not compatible with SQLAlchemy's C-based boolean processor, so MySQL's result-set behavior now follows that of the :class:`.Float` type. A new operator object ``notmatch_op`` is also added to better allow dialects to define the negation of a match operation. fixes #3263
| * - The :meth:`.PGDialect.has_table` method will now query againstMike Bayer2014-12-045-1/+93
| | | | | | | | | | | | | | | | | | | | | | ``pg_catalog.pg_table_is_visible(c.oid)``, rather than testing for an exact schema match, when the schema name is None; this so that the method will also illustrate that temporary tables are present. Note that this is a behavioral change, as Postgresql allows a non-temporary table to silently overwrite an existing temporary table of the same name, so this changes the behavior of ``checkfirst`` in that unusual scenario. fixes #3264
