| ERROR | date or system variable wrongly specified in CHECK constraint |
| CAUSE | An attempt was made to use a date constant or system variable, such as USER, in a check constraint that was not completely specified in a CREATE TABLE or ALTER TABLE statement. For example, a date was specified without the century. |
| ACTION | Completely specify the date constant or system variable. Setting the event 10149 allows constraints like a1 > 10-MAY-96, which a bug permitted to be created before version 8. |
