Subject: Finding invalid data in zoned numeric fields with SQL
I have a file that has bad data showing up in a field. The file was
created
by a third party software vendor, and while we wait for them to find and
fix
the problem, I need to find a way to identify those records with invalid
data, and replace that data with zeros. I would like to do this with
SQL if
I can, but I don't know how to test a numeric field for the hex value of
"40404040" or blanks. Better yet would be to test "Not numeric" (I know
that COBOL can do that test!).
Is there a way to test if a numeric field contains something other than
a
number in SQL?
Thanks!
