* Explicit STARTS syntax * SHOW CREATE * Default STARTS rounding depending on INTERVAL type * Warn when STARTS timestamp is later than query time * Fix uninitialized Lex->create_last_non_select_table under mysql_unpack_partition() Default STARTS rounding depending on INTERVAL type If STARTS clause is omitted, default one is assigned with value derived from query timestamp. The rounding is done on STARTS value depending on INTERVAL type: SECOND: no rounding is done; MINUTE: timestamp seconds is set to 0; HOUR: timestamp seconds and minutes are set to 0; DAY, WEEK, MONTH and YEAR: timestamp seconds, minutes and hours are set to 0 (the date of rotation is kept as current date).
