This reverts commit 550cb3a365dee4edfdd1563224d5304de2a57fda because try/except performs better.

2016-01-23Fixed typo in django/db/backends/sqlite3/operations.py.seungkwon
2016-01-21Fixed #26063 -- Crash when passing > 2000 params.Aymeric Augustin
If SQLITE_MAX_VARIABLE_NUMBER (default = 999) is changed at compile time to be greater than SQLITE_MAX_COLUMN (default = 2000), which Debian does by setting the former to 250000, Django raised an exception on queries containing more than 2000 parameters when DEBUG = True.
2015-09-22Fixed #24509 -- Added Expression support to SQLInsertCompilerAlex Hill
2015-09-17Refs #14091 -- Fixed connection.queries on SQLite.Aymeric Augustin

2015-06-04Fixed #22316 -- Added time filters to TimeField on SQLite.Matthew Somerville
This was implemented for non-SQLite backends in 1.7 (as a side effect of #16187).
2015-06-02Fixed #9596 -- Added date transform for DateTimeField.Jon Dufresne
2015-05-17Fixed #23820 -- Supported per-database time zone.Aymeric Augustin
The primary use case is to interact with a third-party database (not primarily managed by Django) that doesn't support time zones and where datetimes are stored in local time when USE_TZ is True. Configuring a PostgreSQL database with the TIME_ZONE option while USE_TZ is False used to result in silent data corruption. Now this is an error.
2015-05-17Renamed value_to_db_xxx to adapt_xxxfield_value.Aymeric Augustin
This mirrors convert_xxxfield_value nicely, taking advantage of the adapter/converter terminology which is commonly used by DB-API modules.
2015-05-17Normalized the implementation of get_db_converters.Aymeric Augustin
Put the types in the same order and checked for None consistently.
2015-05-17Removed global timezone-aware datetime converters.Aymeric Augustin
Refs #23820.
2015-02-20Update converters to take a consistent set of parameters.Marc Tamlyn
As suggested by Anssi. This has the slightly strange side effect of passing the expression to Expression.convert_value has the expression passed back to it, but it allows more complex patterns of expressions.
