SQL: Incorrect syntax near the keyword 'GROUP'

Question

Code is not executing, syntax is completely correct. I don't understand

SELECT DWCUSTOMER.CUS_CODE, DWPRODUCT.P_CODE, SUM(DWDAYSALESFACT.SALE_UNITS*DWDAYSALESFACT.SALE_PRICE) AS TOTSALES 
FROM DWDAYSALESFACT NATURAL JOIN DWCUSTOMER   
GROUP BY ROLLUP (DWCUSTOMER.CUS_CODE, DWPRODUCT.P_CODE)  
ORDER BY DWCUSTOMER.CUS_CODE, DWPRODUCT.P_CODE;

After execution: Incorrect syntax near the keyword 'GROUP'.

Answer 1

You didn't join the DWProduct table but you selected from it in the first line. Add another join and it should work fine.

Answer 2

尝试：

GROUP BY DWCUSTOMER.CUS_CODE, DWPRODUCT.P_CODE WITH ROLLUP
