Problem: ======= Autoincrement value gives duplicate values because of the following reasons. (1) In InnoDB handler function, current autoincrement value is not changed based on newly set auto_increment_increment or auto_increment_offset variable. (2) Handler function does the rounding logic and changes the current autoincrement value and InnoDB doesn't aware of the change in current autoincrement value. Solution: ======== Fix the problem(1), InnoDB always respect the auto_increment_increment and auto_increment_offset value in case of current autoincrement value. By fixing the problem (2), handler layer won't change any current autoincrement value. Reviewed-by: Jimmy Yang <jimmy.yang@oracle.com> RB: 13748 |
