I need to update text files received for import (not a database file) in

the IFS with only sql (the text files were generated weeks ago, cannot be

regenerated, and a two byte column needs to be updated before processing if

value = 99). I don't have an option to do an emergency release of program

code to fix it (at least not easily), but I can execute sql script with a

simple approval.

Is such a thing possible? It is many files (20 or so) and approx 100,000

rows per file.


psuedo code idea


update '/input/file1.txt'

set (substring,101,2) =

(select ordertype from OrdMaster om

where (substring,11,9) = om.OrderNbr)

where (substring,101,2) = '99'


and the order number in substring,11,9 is a character string matching

OrderNbr which is character.


TIA
