Hi Experts

Some difficulty finding info on except arguments in SQL.  This query works up to line 3. Adding line 4 causes a syntax error . Some resource at EE says there is no "except" in SQL??? Can this query be written another way?

Many thanks

Peter
SQL = SQL & " select [PD_PatID], [PD_FName], [PD_LName]"
        SQL = SQL & " from PATIENT_DETAILS"
        SQL = SQL & " where [PD_Diabetic] = True"
        SQL = SQL & " except where [PD_Addr1] LIKE '*Tricare*'"

Try changing line 4 to:
SQL = SQL & " AND NOT [PD_Addr1] LIKE '*Tricare*'"

Nice job Miss_Sellaneus.

There is an addition concern with your statement:

LIKE '*Tricare*'  is the same as =  '*Tricare*'

I suspect that you intended for the astericks ( * )  to be wildcard characters.  For SQL Server, the wildcard character would be %.  If you, however, you intended for the * characters to be there, then you would be better off using = (equals) instead of LIKE.
