我有一个查询，我需要使用 MS SQL Server 2008 运行一些数据。基本上我有 3 个唯一字段，还有 3 个需要在时间范围内重复。这样我将在主 select 语句中有三个子查询。我一直在尝试仅使用一个子查询使其正常工作，然后复制 n 粘贴其他两个并更改日期范围。

这是我想出的 SQL，但它给了我一个错误。我正在尝试使用子查询，因为我没有创建过程的权限。

SELECT
mon.description as ScriptName,
up0.pageseqnum as PageSeq,
usd.DisplayName as PageName,

--This subquery is the one week old data for the Response Time, Page Weight, and Number of Objects.
(SELECT
ROUND(AVG(CAST(up1.ResponseTime AS FLOAT)* 0.001),3) AS ResponseTime,
ROUND(AVG(CAST(up1.numbytes AS FLOAT)* 0.001), 3) AS NumberofKilobytes,
CONVERT(INT,AVG(up1.numobj),0) AS NumberOfObjects
FROM
table0 AS up1
WHERE
up1.Monitor_Id = up0.Monitor_id
AND up1.TestTime BETWEEN DATEADD(HOUR,4,'2012-05-14 00:00:00') AND DATEADD(HOUR,4,'2012-05-21 00:00:00')
AND ISNULL(up1.ContentMatchStatus,'0')= 0
AND up1.UserScriptStatus = 0
AND up1.TimeoutStatus = 0
AND up1.ResponseTime > 0
) AS CurrentWeek

FROM
table0 (nolock) AS up0
JOIN table1 usd ON up0.Monitor_Id=usd.monitor_id
and up0.PageSeqNum=usd.PageSeqNum
JOIN table3 mon on up0.Monitor_Id = mon.Monitor_id

WHERE
up0.Monitor_Id in (1, 2, 3, 4, 5, 6, 7, 8 ,9 ,10)

GROUP BY up0.Monitor_Id, mon.Description, up0.PageSeqNum, usd.DisplayName
ORDER BY mon.Description ASC;

我希望结果集应该有这些列，并且我可以在本周之后再添加前两周的数据！请滚动查看我所说的结果。

                                | CurrentWeek (子查询) | OneWeekOld (子查询) |
脚本名称 | 页面序列 | 页面名称 | 响应时间 | 千字节数 | 对象数 | 响应时间 | 千字节数 | 对象数 |
测试1 | 0 | 主页 | 1.2 | 50.23 | 56 | 1.2 | 50.23 | 56 |
测试1 | 1 | 出售 | 2.2 | 50.23 | 56 | 1.2 | 50.23 | 56 |
测试1 | 2 | 烘烤 | 3.2 | 50.23 | 56 | 1.2 | 50.23 | 56 |
测试1 | 3 | 蛋糕 | 4.2 | 50.23 | 56 | 1.2 | 50.23 | 56 |
测试2 | 0 | 主页 | 1.2 | 50.23 | 56 | 1.2 | 50.23 | 56 |
测试2 | 1 | 出售 | 2.2 | 50.23 | 56 | 1.2 | 50.23 | 56 |
测试2 | 2 | 烘烤 | 3.2 | 50.23 | 56 | 1.2 | 50.23 | 56 |

任何帮助，将不胜感激。

尝试这样的事情：

SELECT  mon.description as ScriptName,
        up0.pageseqnum as PageSeq,
        usd.DisplayName as PageName,
        wk.ResponseTime,
        wk.NumberofKilobytes,
        wk.NumberOfObjects

FROM
table0 (nolock) AS up0
JOIN table1 usd ON up0.Monitor_Id=usd.monitor_id
and up0.PageSeqNum=usd.PageSeqNum
JOIN table3 mon on up0.Monitor_Id = mon.Monitor_id
CROSS APPLY (   SELECT  up1.Monitor_Id,
                        ROUND(AVG(CAST(up1.ResponseTime AS FLOAT)* 0.001),3) AS ResponseTime,
                        ROUND(AVG(CAST(up1.numbytes AS FLOAT)* 0.001), 3) AS NumberofKilobytes,
                        CONVERT(INT,AVG(up1.numobj),0) AS NumberOfObjects
                FROM table0 AS up1
                WHERE up1.TestTime BETWEEN DATEADD(HOUR,4,'2012-05-14 00:00:00') AND DATEADD(HOUR,4,'2012-05-21 00:00:00')
                AND ISNULL(up1.ContentMatchStatus,'0')= 0
                AND up1.UserScriptStatus = 0
                AND up1.TimeoutStatus = 0
                AND up1.ResponseTime > 0 
                GROUP BY up1.Monitor_Id) wk

WHERE up0.Monitor_Id in (1, 2, 3, 4, 5, 6, 7, 8 ,9 ,10)
AND up0.Monitor_Id = up1.Monitor_Id
ORDER BY mon.Description ASC;

如果您将架构发布在 sqlfiddle.com 上会更容易，然后我可以针对它编写查询以返回您需要的内容。

另外我假设您使用的是 SQL Server，因此使用了 APPLY。请说明您正在使用的数据库系统。
