IBM DB2 Error Message
-416 an operand of a union contains a long string column
Reason for the Error
The UNION specified in the SQL statement could not be performed because one of the tables participating in the union contains a long string column (for example, a VARCHAR column with length greater than 254).� The operands of a UNION cannot contain long string columns.
The implied function is not supported by DB2.
