Let’s say you are building a file from multiple spreadsheets and need to consolidate and remove duplicates. Build your DB2 file without keys load all the spread sheets with *add not *replace then run this SQL using the where statement to match the fields
Delete from ksfcexg F1 where RRN(f1) > (select MIN(RRN(F2)) from
ksfcexg F2 where F2.stcuno = F1.stcuno)
F1 and F2 are the same file
