Hi there. I have a question regarding filtering data that is unique. I know this sounds a bit vague. Let me explain. I have a live table (TableA) with a PK consisting of Field1 + Field2 + Field3. I also have a staging table where data gets loaded into before being pumped into the live table. There is no primary key on this table as they would like to trap duplicates as part of the error logging. My question is this... How would I trap the duplicates when Field1 could appear more than once, Field2 could appear more than once and Field3 could appear more than once. I.e. COUNT(FieldName) will not help as either of these fields can have one value appear more than once. Is there any way I can do an IF EXISTS (find duplicates)?
