I understand how to copy records from one SQL table to another but how can I repeat the query copying only new records. My current query copies all the records and inserts them into the target table but if I repeat the query it copies all the records again into a new set of rows...
INSERT INTO SRSCustom1.dbo.ORDERS
The below query works for a single column but I can't figure out how to make it work for multiple columns...
SELECT * FROM SRSPRM2.dbo.ORDERS
I need help in structuring a query that will copy records from the host table to the target table, skipping records that already exist in the target table.
