Issue Number : 700922a
| Issue | An error occurs where duplicate results are output when there are consts of different types in the IN clause. |
| Cause | When consts have different types, duplicate elimination is not performed by the compiler, so duplicate elimination was needed at execution time. |
| Solutions | When consts of different types exist in the IN clause, the dup_check flag was modified to be set so that duplicate elimination can be performed at run-time. |
