Hi Team,

I've got a MODIFY script that loads a hold file into a table. The job is fast if the hold file is small, and slow if it is large, un-surprisingly.

The table itself is very basic; five fields, no keys. I think the MODIFY job is doing inserts row by row, and I feel that there are probably some performance tuning opportunities here.

This is my code:

 
-SET &ECHO=ALL;
-SET &UNIQUE_ID=&UNIQUE_ID+0;
-SET &HOLDNAME='BORs_'||'&UNIQUE_ID.EVAL'||'_'||'&YYMD.EVAL'||'_'||'&TOD.EVAL';

SET ASNAMES=ON
TABLE FILE FOCCACHE/STEPONE
PRINT
  ID AS BOR_ID
  COMPUTE UNIQUEID/P20=&UNIQUE_ID;
  COMPUTE USER_ACCT/A100='&IBIMR_user';
  COMPUTE LOG_DATE/A10='&YYMD';
  COMPUTE LOG_TIME/A8='&TOD';
ON TABLE HOLD AS &HOLDNAME
END
-SET &NUMBEROFLINES=&LINES;

-** Load the data into the SQL Server table
MODIFY FILE SUMARYFORINVOICING_BOR_IDS_TO_UNIQUE_ID_V2
FIXFORM FROM &HOLDNAME
MATCH BOR_ID UNIQUEID USER_ACCT LOG_DATE LOG_TIME
 ON NOMATCH INCLUDE
   ON MATCH REJECT
CHECK 2000
DATA ON &HOLDNAME
END
-RUN
 


Any advice on making this fly?

Cheers,

Joey

You might want to take a look at the Modify Fastload facility. The syntax is: SQL SET LOADONLY, after the MODIFY command.

Just what I was thinking as well.

FYI

By default, MODIFY will select the record from the DB to see if it needs to update or insert.

I believe that the LOADONLY setting skips the select.
