Question

在 SQL Server 2008 中，有没有办法选择 top @top 通过变量定义值，如下面的代码？

declare @top as integer;
set @top=100;

SELECT top @top
    T1.id as clientInfoId
    ,T1.ucsId
    ,T1.phoneHome
    ... (more columns here)......
    ,T1.businessTitle
FROM
    YELLOW_OUT_CLIENT_INFO AS T1    
LEFT JOIN 
    YELLOW_OUT_BUSINESS T2 on T2.clientInfoId = T1.id
WHERE
    T1.AgentId=5
    AND 
    T1.deleted IS NULL
    ... (more conditions here)......
ORDER BY NEWID()

将变量放在括号中:

SELECT top (@top)

This functionality was added in SQL Server 2005 ... 2000 是您必须执行 SET ROWCOUNT @top
