Symptoms
An SQL statement is sent from IBM DB2 to the Microsoft Service for Distributed Relational Database Architecture (DRDA). If the statement contains a fully qualified quoted identifier such as "SCHEMA1.TABLE1," an error message that resembles the following may be displayed on the IBM host system:
SQLCODE: -204
SQLSTATE: 42704 SQLERRMT: qualifier.” IS AN UNDEFINED NAMECause
This problem occurs because the SQL transformer that is used by the Microsoft Service for DRDA does not correctly parse and update the fully qualified quoted identifiers. Additionally, the SQL transformer does not update the mapped collection name to the schema name based on the settings in the App.config file that is used by the Microsoft Service for DRDA.
