SQL-Server-2008R2

need to pick data from 2 tables.

The tables are 1. COMPLAINT (EMPNO,EMPNAME)
2. UTILITY (EMPNO,EMPNAME)

The query should exclude records in UTILITY which are in COMPLAINT

The field EMPNO is the main reference

SELECT TOP 1 EMPNO ,
EMPNAME FROM COMPLAINT
GROUP BY EMPNO,EMPNAME ORDER BY EMPNO DESC
UNION
SELECT EMPNO,EMPNAME FROM UTILIY
AND UTILITY.EMPNO
NOT IN COMPLAINT

Please assist

Thanks

What I have tried:

Checked my earlier codes in CTE .

Have also checked the Internet. However I never found any example with the 'NOT IN'

IN CTE.

Any referencesites will be most welcomed

Without knowing your tables and exactly what you want to return it's not possible to tell you exactly what to do. But have a look here: Visual Representation of SQL Joins[^] - you probably want one of the three EXCLUDING JOINs, and it gives sample code.
