[SOLVED] DB2 Table Updates

Hello all,

I would like to use mainframe batch Focus to update a DB2 table as follows:
1. Read a flat file record
2. If the record (key) exists on the DB2 table
then update the DB2 row.
3. If the record (key) does not, insert it.

Can anyone provide the pseudo-code for this logic??

Thanks to all,
Ken
Focus 7.2.5 Z/OS IBM mainframe

You could do the insert part with SQL passthrough too.

  
(..initial processing to read flat file and assign values to amper vars...)
-INSERT_LOOP to be processed as many times are needed
SQL DB2
INSERT statement using above amper vars
 ;
TABLE
END
-RUN
-SET &SQL_ERROR1 = &RETCODE;                                            
-TYPE SQL ERROR1: &SQL_ERROR1                                         
-IF (&SQL_ERROR1.EVAL EQ '0' OR &SQL_ERROR1.EVAL EQ -803) GOTO LBL_NXT1;
(else do ERROR processing here)
-LBL_NXT1
(continue processing after sucessful insert)
-INSERT_LOOP_END



The -803 check takes care of the duplicate condition and treats it as successful operation.
All other errors should be handled appropriately.

You could easily do this in Maintain:

MAINTAIN FILE file1 AND file2
FOR ALL NEXT file1.keyfields into stk
FOR ALL REVISE file2.non-key fieldlist from stk
END

Just make sure that you allocate file1 and that the fields in both file are the same.
