-134 There is an improper use of the LONG STRING COLUMN or a host variable of a MAXIMUM LENGTH greater than 254.

Explanation

This column or host variable cannot appear in ORDER BY or GROUP BY clauses, UNION subqueries, subselects, or functions. SUBSTR is the only scalar function that can use long string values. LIKE and NOT LIKE are the only predicates that can use long-string values.

The statement cannot run. The column-name might not be returned in SQLCA, depending on the nature of the error and the syntax in which it occurred.

The requested operation on a long-string value is not supported by DB2.
