sql - 从查询中排除 NULL 时收到错误

Question

我有一个这样的查询:

SELECT distinct [F_Exhibitor_Name],
       F_Site 
  FROM [V_ExhibitorLocation] 
 WHERE F_ExhibitionCode ='10996' is not null 
 ORDER BY F_Exhibitor_Name

但显示错误

Incorrect syntax near the keyword 'is'

.

Answer 1

您必须删除is not null，如下所示

SELECT distinct [F_Exhibitor_Name],F_Site 
FROM [V_ExhibitorLocation] 
Where F_ExhibitionCode ='10996' 
order by F_Exhibitor_Name

或使用不能为空的字段添加条件，如下所示

SELECT distinct [F_Exhibitor_Name],F_Site 
FROM [V_ExhibitorLocation] 
Where F_ExhibitionCode ='10996' 
and  [column]   is not null 
order by F_Exhibitor_Name
