关于我的 SQL 脚本的两个问题。如何添加小计/总计行以及排序问题
我有一些 T-SQL 可以生成一份很好的报告,按月总结一些内容。
我有 2 个问题,有没有办法让按日历顺序而不是按 alpha 对月份进行排序?而且,我想做的是添加每年的总行以及整个报告的总行?
SELECT
CASE WHEN tmpActivity.Year IS NULL THEN
CASE WHEN tmpCreated.Year IS NULL THEN
CASE WHEN tmpContactsCreated.Year IS NULL THEN
null
ELSE tmpContactsCreated.Year END
ELSE tmpCreated.Year END
ELSE tmpActivity.Year END As Year,
CASE WHEN tmpActivity.Month IS NULL THEN
CASE WHEN tmpCreated.Month IS NULL THEN
CASE WHEN tmpContactsCreated.Month IS NULL THEN
null
ELSE DateName(month, DateAdd(month, tmpContactsCreated.Month - 1, '1900-01-01' )) END
ELSE DateName(month, DateAdd(month, tmpCreated.Month - 1, '1900-01-01' )) END
ELSE DateName(month, DateAdd(month, tmpActivity.Month - 1, '1900-01-01' )) END As Month,
CASE WHEN tmpActivity.ActiveAccounts IS NULL THEN 0 ELSE tmpActivity.ActiveAccounts END AS ActiveAccounts,
CASE WHEN tmpCreated.NewAccounts IS NULL THEN 0 ELSE tmpCreated.NewAccounts END AS NewAccounts,
CASE WHEN tmpContactsCreated.NewContacts IS NULL THEN 0 ELSE tmpContactsCreated.NewContacts END AS NewContacts
FROM
(
SELECT YEAR(LastLogon) As Year, MONTH(LastLogon) As Month, COUNT(*) As ActiveAccounts
FROM Users
WHERE LastLogon >= '1/1/1800'
GROUP BY YEAR(LastLogon), MONTH(LastLogon)
) as tmpActivity
FULL JOIN
(
SELECT YEAR(Created) As Year, MONTH(Created) As Month, COUNT(*) As NewAccounts
FROM Users
WHERE Created >= '1/1/1800'
GROUP BY YEAR(Created), MONTH(Created)
) as tmpCreated ON tmpCreated.Year = tmpActivity.Year AND tmpCreated.Month = tmpActivity.Month
FULL JOIN
(
SELECT YEAR(Created) As Year, MONTH(Created) As Month, COUNT(*) As NewContacts
FROM Contacts
WHERE Created >= '1/1/1800'
GROUP BY YEAR(Created), MONTH(Created)
) as tmpContactsCreated ON tmpContactsCreated.Year = tmpCreated.Year AND tmpContactsCreated.Month = tmpCreated.Month
Order By Year DESC, Month DESC
I have some T-SQL that generates a nice report giving a summary some stuff by month.
I have 2 questions, is there a way to get the to sort the months by calendar order, not by alpha? And, what i would like to do is add a total line for each year, and a total line for the whole report?
SELECT
CASE WHEN tmpActivity.Year IS NULL THEN
CASE WHEN tmpCreated.Year IS NULL THEN
CASE WHEN tmpContactsCreated.Year IS NULL THEN
null
ELSE tmpContactsCreated.Year END
ELSE tmpCreated.Year END
ELSE tmpActivity.Year END As Year,
CASE WHEN tmpActivity.Month IS NULL THEN
CASE WHEN tmpCreated.Month IS NULL THEN
CASE WHEN tmpContactsCreated.Month IS NULL THEN
null
ELSE DateName(month, DateAdd(month, tmpContactsCreated.Month - 1, '1900-01-01' )) END
ELSE DateName(month, DateAdd(month, tmpCreated.Month - 1, '1900-01-01' )) END
ELSE DateName(month, DateAdd(month, tmpActivity.Month - 1, '1900-01-01' )) END As Month,
CASE WHEN tmpActivity.ActiveAccounts IS NULL THEN 0 ELSE tmpActivity.ActiveAccounts END AS ActiveAccounts,
CASE WHEN tmpCreated.NewAccounts IS NULL THEN 0 ELSE tmpCreated.NewAccounts END AS NewAccounts,
CASE WHEN tmpContactsCreated.NewContacts IS NULL THEN 0 ELSE tmpContactsCreated.NewContacts END AS NewContacts
FROM
(
SELECT YEAR(LastLogon) As Year, MONTH(LastLogon) As Month, COUNT(*) As ActiveAccounts
FROM Users
WHERE LastLogon >= '1/1/1800'
GROUP BY YEAR(LastLogon), MONTH(LastLogon)
) as tmpActivity
FULL JOIN
(
SELECT YEAR(Created) As Year, MONTH(Created) As Month, COUNT(*) As NewAccounts
FROM Users
WHERE Created >= '1/1/1800'
GROUP BY YEAR(Created), MONTH(Created)
) as tmpCreated ON tmpCreated.Year = tmpActivity.Year AND tmpCreated.Month = tmpActivity.Month
FULL JOIN
(
SELECT YEAR(Created) As Year, MONTH(Created) As Month, COUNT(*) As NewContacts
FROM Contacts
WHERE Created >= '1/1/1800'
GROUP BY YEAR(Created), MONTH(Created)
) as tmpContactsCreated ON tmpContactsCreated.Year = tmpCreated.Year AND tmpContactsCreated.Month = tmpCreated.Month
Order By Year DESC, Month DESC

要按月排序,请使用以下命令:
DatePart()
返回指定部分的整数,1 表示一月,2 表示二月等。您的 SQL 可以使用 COALESCE() 和 ISNULL( ) 函数。这与您的第一个选择相同:
我认为您的选择中有一个错误,我相信您的最后一行必须是这样的:
但我必须对此进行测试以确定。
添加汇总很难做到——通常这是在控件中的 SQL 或任何显示结果的外部完成的。您可以这样做(人为的示例):
或者您不能拥有“额外”总计列并将其放入金额列中。
To order by the month use the following:
DatePart()
returns an integer for the part specified 1 for January, 2 for Febuary etc.You're SQL could be helped with the COALESCE() and ISNULL() functions. This is the same as your first select:
I think there is a bug in your select, I believe your last line has to be this:
But I would have to test this to be sure.
Adding in rollups is hard to do -- typically this is done externally to the SQL in the control or whatever displays the results. You could do something like this (contrived example):
or you could not have the "extra" total column and put it in the amount column.
