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?
