I am loading sas data converted to csv into DB2. one problem is when  I setup tables in DB2, I added keys and the keys are usually the merge by columns. and these keys are not nullable. So if in sas data, key is null then when I load into DB2, the entries with null key would be rejected automatically. And my uat and prod data might not match. how can I overcome this? is it a good way if I transferred null to empty string so it wouldnt be rejected by db2?

"Empty" is the same as "missing" for SAS character variables.

Today, most keys are UUIDs, and you can create such with the UUIDGEN function; format them to the readable 36-character notation for the csv file.

If we are talking about strings, yes it could be done this way.

Remember that the key still needs to be unique.

I think yuo should take care of your data quality problem first before loading to DB2.
