要创建一个可以每个小时报告的查询，首先要创建一个表格。该表格一列记录日期，而没有时间信息；另一列记录钟点。下面的表格有一列记录了不同的处理类型。例如，我们可以按小时找出处理类型的总数。;

CREATE;TABLE;test
(StartTime;DATETIME;NOT;NULL
DEFAULT;CURRENT_TIMESTAMP,
StartDate;DATETIME;NOT;NULL
DEFAULT;CONVERT(DATETIME,;CONVERT(CHAR(10),CURRENT_TIMESTAMP,;110)),
StartHour;INT;NOT;NULL
DEFAULT;DATEPART(hh,CURRENT_TIMESTAMP),
TranType;INT;NOT;NULL
CONSTRAINT;ck_TranType;CHECK;(;TranType;IN
(;
1,;--;insert
2,;--;update
3,;--;delete
)
DEFAULT;1
)
GO;
接下来，插入test的数据来模拟一个可能的样本。

INSERT;test;(StartTime,;TranType);VALUES;(CURRENT_TIMESTAMP,;3)
INSERT;test;(StartTime,;TranType);VALUES;(CURRENT_TIMESTAMP,;2)
INSERT;test;(StartTime,;TranType);VALUES;(CURRENT_TIMESTAMP,;3)
GO

DECLARE;@hr;int
SET;@hr;=;DATEPART(hh,;DATEADD(hh,-1,CURRENT_TIMESTAMP);)

INSERT;test;(StartTime,;TranType,;StartHour);_
;;VALUES;(DATEADD(hh,-1,CURRENT_TIMESTAMP),;3,;@hr)
INSERT;test;(StartTime,;TranType,;StartHour);_
;;VALUES;(DATEADD(hh,-1,CURRENT_TIMESTAMP),;1,;@hr)
INSERT;test;(StartTime,;TranType,;StartHour);_
;;VALUES;(DATEADD(hh,-1,CURRENT_TIMESTAMP),;2,;@hr)
GO;

然后用一个查询来找出按日和小时的处理总数。

SELECT;StartDate;tran_day,
StartHour;tran_hour
,;CASE;trantype;WHEN;1;THEN;'insert'
WHEN;2;THEN;'update'
WHEN;3;THEN;'delete'
ELSE;'unknown'
END;trantype,
COUNT(*);tran_total
FROM
Test
GROUP;BY
StartDate,
StartHour
,trantype
ORDER;BY;StartDate,;StartHour
COMPUTE;SUM(COUNT(*));BY;StartDate,;StartHour
GO
;
去掉test可以清空test表格。

DROP;TABLE;test
GO;
