Sql server 2005 简单sql查询

我在这个查询中遇到了一个错误，比如distinct语句附近的语法不正确

DECLARE  @CNT INT
SELECT @CNT= DISTINCT ISNULL(Employee.id,0)
FROM Employee 
WHERE EMPLOYEE.NAME='KIRAN'

语法有什么错误吗

SELECT  DISTINCT ISNULL(Employee.id,0)
FROM Employee 
WHERE EMPLOYEE.NAME='KIRAN'

这句话很好用

DECLARE  @CNT INT
SELECT top 1 @CNT= ISNULL(Employee.id,0)
FROM Employee 
WHERE EMPLOYEE.NAME='KIRAN'

谢谢

也许是这样的

DECLARE  @CNT INT
SET @CNT = (SELECT DISTINCT ISNULL(Employee.id,0)
FROM Employee 
WHERE EMPLOYEE.NAME='KIRAN')

1.use必须在@CNT变量之前写入distinct
2.仅选择第一行，因为@cnt不是表变量，它是类型为int的变量

DECLARE  @CNT INT
SELECT top 1 @CNT= ISNULL(Employee.id,0)
FROM Employee 
WHERE EMPLOYEE.NAME='KIRAN'

您可以简单地测试它

declare @CNT INT

SELECT top 1 @CNT= ISNULL(Employee.id,0)
FROM Employee 
WHERE EMPLOYEE.NAME='KIRAN'

select @CNT

那你就有麻烦了。。但这不是问题所在，查询返回相同的值，即使是多行值
