I take it this table was not created using DDL but rather DDS? DDL created
table ought to have prevented invalid input in the first place.

Perhaps something like this will work for you:

select rrn(a),hex(myField), myField from myLib/myFile a
where hex(myField) = '40404040'

or more generic:

select rrn(a),hex(myField), myField from myLib/myFile a
where substring(hex(myField),1,1) <> 'F'

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!

Jim
