Issue Number: 700391a
| Issue | There was an issue where the result value would differ when using the IGNORE NULLS option. |
| Cause | The IGNORE NULLS option is a function that ignores NULL values when searching for a value, and if there is no valid value, NULL may be output. However, in the NONNULL determination logic, when the IGNORE NULLS option was specified, it was always set to determine as NONNULL. |
| Solutions | It has been modified so that the IGNORE NULLS option does not affect the determination of NONNULL status. |
