Oracle Solution for Error ora-02436

ORA-02436: date or system variable wrongly specified in CHECK constraint

What triggered the Error:

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.

What should we do to fix it:

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.
