Subject: SQL issue with EXISTS not "working"
I need some help on this one.
I am merging 5 company records into 1 file and need to drop any duplicates.
This is the statement:
INSERT INTO COMMON_FILE
(SELECT * FROM FILE_A A1
WHERE NOT EXISTS (SELECT 1 FROM COMMON_FILE A2 WHERE A1.ITEM = A2.ITEM))
Problem:
The exists is not working and as a result the insert is inserting duplicates.
What alternative ways are there to achieve this merge or what mistake am I not seeing?
I have 5 similar SQL statements to run.
TIA
