@@ -27,6 +27,14 @@ Version 2.3.0 to the ODB compiler command line interface documentation (man pages) for details. + * Starting with MySQL version 5.6.4 it is possible to store fractional + seconds up to microsecond precision in TIME, DATETIME, and TIMESTAMP + columns. Both Boost and Qt profiles have been updated to support this + new functionality. Note, however, that to enable sub-second precision, + the corresponding type with the desired precision has to be specified + explicitly. For details, refer to the "MySQL Database Type Mapping" + sections in the Boost and Qt profile chapters. + * New SQLite-specific exception, odb::sqlite::forced_rollback, which is thrown if SQLite forces a transaction to roll back. For more information, refer to Section 16.5.6, "Forced Rollback" in the ODB manual. |
