sql – 会见更换EXCEPT子句

如安在ms会见中得到与下面的SQL代码沟通的功效？它不认可EXCEPT条款……

SELECT DISTINCT 
       P.Name,T.Training
  FROM Prof AS P,Training_done AS TC,Trainings AS T
 WHERE (P.Name Like '*' & NameProf & '*') 
   AND (P.Primary_Area = T.Cod_Area)
EXCEPT
SELECT DISTINCT 
       P.Name,Trainings AS T
 WHERE (P.Name Like '*' & NameProf & '*') 
   AND (P.Cod_Prof = TC.Cod_Prof);

提前叩谢！

办理要领

SELECT DISTINCT 
       P.Name,Trainings AS T
 WHERE ((P.Name Like '*' & NameProf & '*') AND
        (P.Primary_Area = T.Cod_Area)) 
   AND NOT ((P.Name Like '*' & NameProf & '*') AND
            (P.Cod_Prof = TC.Cod_Prof));
