ORA-02436: 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
