我有一个使用VriHistoryEventID = 7保持登录的列occuredAt和使用VriHistoryEventID = 8的LogOut现在，我想创建一个查询，可以按InitiatorID选择数据组，然后按日期登录并在同一行中注销
谢谢

你可以尝试这样的事情
SELECT InitiatorID,
MAX(CASE WHEN VriHistoryEventID = 7 THEN OccurredAt ELSE NULL END) [Login],
MAX(CASE WHEN VriHistoryEventID = 8 THEN OccurredAt ELSE NULL END) [Logout]
FROM @table
GROUP BY InitiatorID,CONVERT(DATE,OccurredAt)
编辑2 此查询将在一天内显示多个登录和注销
DECLARE @table TABLE
(
VriHistoryID INT,
OccurredAt DATETIME,
VriHistoryEventID INT,
InitiatorID INT
)
INSERT INTO @table values(1,'2012-08-23 03:28:32.000',8,NULL)
INSERT INTO @table values(4,'2012-08-24 03:47:19.640',8,5)
INSERT INTO @table values(5,'2012-08-24 03:47:50.170',7,5)
INSERT INTO @table values(7,'2012-08-24 03:48:05.407',8,5)
;WITH CTE AS
(
SELECT
InitiatorID,
VriHistoryEventID,
(CASE WHEN VriHistoryEventID = 7 THEN OccurredAt ELSE NULL END) [Login],
(CASE WHEN VriHistoryEventID = 8 THEN OccurredAt ELSE NULL END) [Logout],
ROW_NUMBER() OVER(PARTITION BY InitiatorID,VriHistoryEventID ORDER BY OccurredAt) rn
FROM @table
)
SELECT InitiatorID,MIN(Login) Login,MIN(Logout) Logout
FROM CTE C1
GROUP BY InitiatorID,rn
ORDER BY InitiatorID,rn
编辑3 根据预期的更新输出更新了示例SQL。 见SQL Fiddle
CREATE TABLE #table
(
VriHistoryID INT,
OccurredAt DATETIME,
VriHistoryEventID INT,
InitiatorID INT
)
INSERT INTO #table values(1,'2012-08-23 03:28:32.000',8,NULL)
INSERT INTO #table values(4,'2012-08-24 03:47:19.640',8,5)
INSERT INTO #table values(5,'2012-08-24 03:47:50.170',7,5)
INSERT INTO #table values(7,'2012-08-24 03:48:05.407',8,5)
;WITH CTE AS
(
SELECT

CONVERT(DATE,OccurredAt) OccurredDate,

ROW_NUMBER() OVER(PARTITION BY InitiatorID,CONVERT(DATE,OccurredAt), VriHistoryEventID ORDER BY OccurredAt) rn

对于SQL Server 2012 +：
DECLARE @t TABLE
(
ID INT ,
D DATETIME ,
E INT ,

)
INSERT INTO @t
VALUES ( 1, '2012-08-23 03:28:32.000', 8, NULL ),
