我使用的是sql server 2000,因此无法使用CTE的
DECLARE @reportdate AS DATETIME
SET @reportdate='08/26/2013'
第一次查询
SELECT SUM(NENTEREDACD) AS calls,
DINTERVALSTART
FROM dbo.QUEUESTATS
WHERE ( DINTERVALSTART > @reportdate + ' 00:00:00.000' )
AND ( DINTERVALSTART < DATEADD(d, 1, @reportdate) + ' 00:00:00.000' )
GROUP BY DINTERVALSTART
ORDER BY DINTERVALSTART
第二次查询
SELECT count(cname) AS AvaiAgents,
dintervalstart AS startdatetime
FROM (SELECT dintervalstart,
cname
FROM [dbo].[AGENTSTATS]
GROUP BY dintervalstart,
cname
HAVING ( DINTERVALSTART > @reportdate + ' 00:00:00.000' )
AND ( DINTERVALSTART < DATEADD(d, 1, @reportdate) + ' 00:00:00.000' )) T
GROUP BY T.dintervalstart
第3次查询
SELECT count(cname) AS ActiveAgents,
dintervalstart AS startdatetime
FROM (SELECT dintervalstart,
cname
FROM [dbo].[AGENTSTATS1]
GROUP BY dintervalstart,
cname
HAVING ( DINTERVALSTART > @reportdate + ' 00:00:00.000' )
AND ( DINTERVALSTART < DATEADD(d, 1, @reportdate) + ' 00:00:00.000' )) T
GROUP BY T.dintervalstart
我只想从第一个查询中仅提取记录,所以它应该是类似的 所以我需要从三个不同的查询中获得三列。常见的是时间戳
I inetval Calls Avaiagents Active agents
08/26/2012 20 22 23
答案 0 :(得分:0)
cte只是带有using关键字的派生表。你能用老式的方式做到吗?
select somefields
from a_table join
(select etc) temp on t.something = a_table.something
