This is weird:
I have a call to
DatabaseMetaData.getPrimaryKeys(null, "EMP", "Employees");
that works perfectly in Java, on my Mac, accessing both DB2/400 and
MySQL, and works perfectly from RPG if I'm accessing DB2/400. Yet if I
try to call it on a MySQL database from RPG, it throws an exception that
shows up in the joblog as
Incorrect database name ''" when calling method "getPrimaryKeys"
I know that the DatabaseMetaData object is valid, because it shows up as
nonzero in the debugger, and an earlier call had successfully retrieved
both the driver version and the product name from the DBMD. And I know
that the catalog parameter is genuinely being passed as null, and the
schema and table are not.
Please see my query on the RPG list
