Answer 1

您需要使用T-SQL检查计数是否大于5并执行其他操作，如此SQL Fiddle。

IF ((select count(*) from jobs where name like 'Server%' and Status = 1) >= 5)
BEGIN
    SELECT 1
END

Answer 2

也许像

SELECT [Status Count Greater Than 5] = case when Count(*) > 5 then 1 else 0 end
FROM [dbo].[Jobs_Status]
where Name like 'Server%' and Status = 1

Answer 3

试试这个：

SELECT Name  
FROM [dbo].[Jobs_Status](nolock) 
where Name like 'Server%' 
 and Status=1
and 
(select count(*) from  [dbo].[Jobs_Status](nolock) where Name like 'Server%' and Status=1) >5
