RE: DB2 SQL

["Xu, Weining" <Weining.Xu@xxxxxxx>]

Paul,
Thanks for your response.  I have checked all tables (physical files) in my
DB2 database.  They all have REUSEDLT set as YES. But I have experienced
that some tables do not reset RRN after deleting old records. 

Yes, I am using SQL "delete all" statement because it is part of the process
my Java program does. I try to not drop the table then create the table
again, which I believe it is not efficient. All I need is to have either a
SQL statement or AS400 command that can be executed inside my Java program
without stop the whole process.

I assume that you are using an SQL "delete all" statement to "clear" the
file; if you used the AS/400 CLRPFM command, you wouldn't need to ask this
question.  However, if you can't use CLRPFM the simplest way to solve your
question is to change the physical file to REUSEDLT(*YES).  Then the first
record added after you delete all of the records will reuse relative record
number 1, and so on.

I am using JDBC to process DB2 data on AS400 in a Java application. A table
in Db2 database will be cleared every month after the monthly batch process
and then re-load the data. Before loading the new data,  I want to reoganize
this table after the data are deleted in order to have RRN reset to zero.
How to do this in SQL?  So I can execute SQL statement to the database in my
Java program.  Thanks for your help.
