SQL0332N Character conversion from the source code page "0" to the target code page "<database codepage>" is not supported

Problem

SQL0332N error received when executing CLI application using a DB2 Client or Driver from DB2 Version 9.7 fix pack 6 (9.7.0.6), or DB2 Version 9.7 fix pack 5 (9.7.0.5). Two scenarios may generate this symptom: 1. When connection string passed to SQLDirverConnect() contains an invalid attribute that results only in a warning message CLI004W. The connection to the database would be successful with warning (SUCCESS_WITH_INFO), but several of the DB2 CLI APIs against this database may throw the -332 error further down the application logic. The problem has been seen with SQLGetCursorName() API 2. When attempting to access a DRDA nickname in a Federation Server environment with trusted context connection enabled. Though most of statements that access the nickname would be successful, several of them may fail with the -332 error. For example: -DELETE FROM WHERE (SELECT * FROM FETCH FIRST N ROWS ONLY) -UPDATE SET set_clause (NOTE: problem happens if set_clause cannot be pushed down to remote) -DELETE FROM WHERE CURRENT OF -UPDATE SET set_clause WHERE CURRENT OF
