Re: Starting to experiment with Scott Klement's JDBCR4 -- what's the DB2/400 equivalent to MySQL "USE"

["James H. H. Lampert" <jamesl@xxxxxxxxxxxxxxxxx>]

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?
