Shell scripting exists and is loosely monitored. No access to the server
other than a directory of shell scripts-kornshell (my limited understanding
of the scripts, but have modified or created several), an import directory,
an export directory.
Plus the db2 sql scripts. We do have a few shell scripts executing sql

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.
