Question

我有这样的查询：

SELECT  em.Ename 
FROM    dbo.Email_tbl e 
JOIN dbo.EmployeeMaster_tbl em ON em.Ecode = e.ECode
WHERE e.plcid='25'

给了我这样的输出：

Ename

我有另一个这样的查询：

SELECT e.Ename 
from dbo.EmployeeMaster_tbl e 
WHERE e.gid not IN(SELECT did 
                   FROM dbo.Designation_tbl d 
                   WHERE d.Dname ='Driver'  )

我得到这样的输出：

Ename

Benzy P A

Kauser Mohammad
Rasheed Pulakkuttathil
Lakshuman Perappan

akbar
Alaudddin

我需要为第一个查询中不存在的行输出ename。

所以我尝试了这样的查询：

SELECT e.Ename 
from dbo.EmployeeMaster_tbl e 
WHERE e.gid not IN(SELECT did 
                   FROM dbo.Designation_tbl d 
                   WHERE d.Dname ='Driver') 
and not in (SELECT  em.Ename 
            FROM  dbo.Email_tbl e 
            JOIN dbo.EmployeeMaster_tbl em ON em.Ecode = e.ECode 
            WHERE e.plcid='25')
order by e.Ename

但是我在关键字in附近收到了错误的语法错误。

Answer 1

SELECT e.Ename from dbo.EmployeeMaster_tbl e 
WHERE e.gid not IN 
(SELECT did 
FROM dbo.Designation_tbl d
 WHERE d.Dname ='Driver') 
 and e.name not in (SELECT  em.Ename 
 FROM  dbo.Email_tbl e 
JOIN dbo.EmployeeMaster_tbl em 
ON em.Ecode = e.ECode 
WHERE e.plcid='25')
order by e.Ename

Answer 2

试试这个，你在条件

中缺少e.Ename

SELECT e.Ename from dbo.EmployeeMaster_tbl e 
 WHERE e.gid not IN(SELECT did FROM dbo.Designation_tbl d WHERE d.Dname ='Driver') 
 and e.Ename not in (SELECT  em.Ename FROM  dbo.Email_tbl e 
 JOIN dbo.EmployeeMaster_tbl em ON em.Ecode = e.ECode WHERE e.plcid='25')
 order by e.Ename

而在sql中使用多个获取错误
