Almost certainly.
I believe that what Mr. Woodger meant was to run the query once, and then to reuse either DCLTB99-TRANS.SEQ-ID OR SOF-TRANS-SEQ-ID , whichever you decide to derive directly from the DB2 table.

| Nic - If i create INDEX as below on the table CREATE INDEX INX_SEQ_ID ON test_table (SEQ_ID) and then run this query EXEC SQL SELECT MAX(SEQ_ID) INTO :DCLTB99-TRANS.SEQ-ID :SOF-TRANS-SEQ-ID FROM TEST_TABLE END-EXEC Will this reduce the cost...?? |
Almost certainly.

SELECT SEQ_ID FROM TEST_TABLE and store the values in a PS file and then applying SORT to find the highest... Will this work...??? |
