Re: Finding invalid data in zoned numeric fields with SQL

select * from file where hex(decfield) like '40%'

Would that work for you?

PM 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!

Jim
