IBM DB2 Error Message
-121 the column name is identified more than once in the insert or update statement
Reason for the Error
The same column ‘name’ is specified more than once, either in the list of object columns of an INSERT statement, or the SET clause of an UPDATE statement.
Correct the syntax of the statement so that each column name is specified only once.
