Re: ResultSet problem

We had this problem as well with some data that is maintained by legacy
means (non-sql) on our iSeries.  The problem is that when trying to read
those rows, and TimeStampException (or something like that) is occurring.
My guess is that your code is discarding the row if that happens.  If you
look at the DB2 reference for Date Values at
http://publib.boulder.ibm.com/iseries/v5r1/ic2924/info/db2/rbafzmstch2datetime.htm

there is a sentance under the "Date" section that I think explains the
problem.  "The date formats *JUL, *MDY, *DMY, and *YMD can only represent
dates in the range 1940 through 2039."

What we realized was that the developer would set values of 0001-01-01 when
they didn't want to store any date.  They did this because they didn't want
to have to deal with NULL maps in thier COBOL or RPG code.  So we ended up
changing these to a real NULL value, and changing the legacy code to check
for NULLS.  The funny thing was that the code to check for NULLs in the
legacy code was basically the same as the code they had in there for
checking for 0001-01-01 values. :)

Hope this helps!

I have a table on my iSeries that has date fields with a value of
0001-01-01
(default value) in some of the records.  When I run a JDBC SQL statement
against this I don't get the same amount of records when I do the SQL from
a
green screen.  I get 2 records in the resultset from the Java program and
15
(the correct amount) when I do it from the green screen.  When I change the
date fields to have a more current date like 2003-07-07 it works just fine
from the Java program.

Anybody clue me in as to what is happening?
