Thanks, Scott and Coy; "SET SCHEMA" worked, and the test program got as
far as creating and populating RPGTEST.
But then I ran into another error that really blew things up: DB2/400
didn't like the double quotes in the test query, and I ended up with
multiple dumps going both to STDOUT and to spool files. As soon as I
changed them to single quotes, everything worked perfectly.
Hmm. So MySQL "USE FOO" and DB2/400 "SET SCHEMA FOO" are more-or-less
equivalent. And DB2/400 doesn't like "USE FOO," and it appears that
MySQL doesn't like "SET SCHEMA FOO."
That adds complexity to the task of writing something that can talk to
any database that has a JDBC driver. Then again, now that I think about
it, the nature of my project suggests that I'm either going to be fully
qualifying every table name, every time I call anything that takes a
table name, or specifying the schema when opening the connection. (Which
would work better?)
And Scott: Thanks for your detailed response Now that the immediate
problem is solved, I'm going to re-read it in depth, in order to learn
as much as I can from it. How are you feeling?
