Cannot execute projects if database value is specified

[CR #556364] If you enable the “Use IQ Multiplex” option in the DB Bulk Load Sybase IQ, IQ Loader File via Load Tables, and IQ Loader DB via Insert Location components, to select writers in an IQ multiplex environment, specifying a database in the “Database” property field may display an error during project execution.

Workaround: Do not specify a database in the “Database” property field when “Use IQ Multiplex” option is selected.
