SQL QUERY ISSUE（NOT IN）

Question

select NAME 
from Temp_EMP 
where name not in select NAME from EMPLOYEE and deptid ='11' 

我在声明中收到错误。

Answer 1

你缺少子查询的WHERE条款：

select NAME from Temp_EMP where name not in (select NAME from EMPLOYEE WHERE deptid ='11') 

Answer 2

尝试

select [NAME] from Temp_EMP where [name] not in (select NAME from EMPLOYEE) and deptid ='11' 

或者说，我认为这是一个比较优化：

Select [Name] from temp_emp t left join 
employee on e on t.[name]=e.[name] 
where e.[name] is null and t.deptid = '11' 

Answer 3

Verrigo接近，但我认为它应该更像这样：

select [NAME] 
from Temp_EMP 
where name not in (
    select [Name] 
    from EMPLOYEE 
) and deptid = '11' 

我假设deptid是Temp_EMP列，而deptid其实一些文本字段。
