Re: JDBC native driver/code page conversion

["Richard Dettinger" <cujo@xxxxxxxxxx>]

Wow, that's kinda weird.  The driver should not care at all about the
difference between select * and select <column>.  That's really a parser
detail.

I assume from this description that you can do this in a simple stand alone
program.  If so, run the code from the CL command line the following two
ways.

Assuming there are two programs called "SelectStar" and "SelectSpecific",
run these:

java SelectStar
prop((jdbc.db2.cli.trace true)
     (jdbc.db2.trace.config 'file:///SelectStar.txt'))

java SelectSpecific
prop((jdbc.db2.cli.trace true)
     (jdbc.db2.trace.config 'file:///SelectSpecific.txt'))

This will create the two specified text files in the IFS root directory.

E-mail these directly to me and any other important info I may need about
the the situation.  I'll take a look and see if I can figure something out.
If it's a general issue/bug/etc.  I'll post to the group with the solution.
Otherwise I'll just work with you directly on it.

Subject:  JDBC native driver/code page conversion



I'm using the native AS/400 JDBC driver. The following code works fine:

------------------------------------------------
query = "SELECT * FROM GDPF WHERE GDUSID=?";
pstmt = con.prepareStatement(query);
pstmt.setString(1, equser);
rs = pstmt.executeQuery();

while (rs.next()) {

String option = rs.getString("GDOID");
.
.
.
------------------------------------------------

but when I replace "SELECT *" with "SELECT GDOID" (that's the only field of
the result set I'm actually interested in) rs.getString("GDOID") returns a
garbled value (it looks like it's not properly converted from EBCDIC,
although I may be wrong). CCSID of the file is set to 37 but no specific
CCSID was defined for GDOID field. CCSIDs of the system and the jobs
involved are all set to 37.

What's wrong? Or could it be that the driver is working as designed?
