我有一个包含以下列的表:
Date ReportDate Received Answered Average Wait Time
5/1/2015 5/3/2015 10 10 0:00:04
5/1/2015 5/3/2015 10 10 0:00:10
5/1/2015 5/3/2015 4 4 0:00:02
5/1/2015 5/3/2015 5 5 0:00:03
5/2/2015 5/3/2015 10 10 0:00:09
5/2/2015 5/3/2015 9 9 0:00:03
5/2/2015 5/3/2015 12 12 0:00:09
5/2/2015 5/3/2015 15 15 0:00:02
5/2/2015 5/3/2015 20 20 0:00:10
Total 95 95 0:00:07
我想计算总数并根据不同的报告日期将其存储在不同的表中,例如: -
ReportDate TotalReceivedContacts TotalAnsweredContacts TotalAverageWaitTime
5/3/2015 95 95 0:00:07
像这样我有很多基于ReportDate的行。请帮忙。
答案 0 :(得分:4)
试试这个:
SELECT ReportDate, SUM(Received) AS TotalReceivedContacts,
SUM(Answered) AS TotalAnsweredContacts, AVG(AverageWaitTime) AS TotalAverageWaitTime
FROM Table
GROUP BY ReportDate
答案 1 :(得分:1)
SELECT SUM(Received) AS TotalReceivedContacts,SUM(Answered) AS
TotalAnsweredContacts , AVG(WaitTime) AS TotalAverageWaitTime FROM
YourTableName group by ReportDate
试试这个:)
答案 2 :(得分:0)
这应该有效:
SELECT ReportDate, SUM(Received) as ReceivedSum,
SUM(Answered) as AnsweredSum ,AVG(WaitTime) as WaitTimeAVG
FROM a
GROUP BY ReportDate
ORDER BY ReportDate
请参阅SQL Fiddle
答案 3 :(得分:0)
试试这个。
INSERT INTO another_table_name (ReportDate,TotalReceivedContacts,TotalAnsweredContacts,TotalAverageWaitTime)
SELECT ReportDate,SUM(Received) AS TotalReceivedContacts,SUM(Answered) AS
TotalAnsweredContacts, AVG(Average Wait Time) as TotalAverageWaitTime FROM
table_name GROUP BY ReportDate ORDER BY ReportDate
注意:" another_table_name"将是您数据库中的现有表,此查询将插入您从" table_name"中选择的所有数据。 to" another_table_name"。
