Hi,
I have a table (CTL_Sup) which has 25k records all with a Cust_ID
I have another table (Cont_all) which has 450k records all with a Cust_ID
Within the Cont_all table, we have the 25k records included that are in the CTL_Sup and what I want to do, is remove these 25k accounts from the Cont_all table
Any idea how I would write a query to do this please? I hope this makes sense,
