sql同一天
Ⅰ sql查询语句 如何同一天同一人的记录合并到一起
select distinct intime,user from TableName
或者
Select intime,user from TableName group by intime,user
Ⅱ sql语句实现考勤报表,sql语句怎样实现员工同一天只有两次考勤
两次考勤:select 员工ID,TRUNC(TIME,'d') FROM 考勤表 group by 员工ID,TRUNC(TIME,'d')
having count(*)=2;
漏打:select 员工ID,TRUNC(TIME,'d') FROM 考勤表 group by 员工ID,TRUNC(TIME,'d')
having count(*)<2;
Ⅲ MS-SQL查询:显示同一天内多行数据的总和
首先你的意思 其实是分组求和的意思,对日期进行分组,对金额进行求和,那么这样就存在一个问题:你是想求和之后每一天 都只显示一条求和后的数据是吧,那么你的第二列 就不应该显示,因为同一天里的多条数据里面,第二列是不同的,不能进行分组。那么排除第二列后就好办了:
SELECT longhuDate ,longhuYingyesuo ,SUM(longhuBuy) ,SUM(longhuSell) ,SUM(longhuOnly)FROM [stormLonghubang]
where [longhuYingyesuo]='国泰君安证券上海福山路营业部'
GROUP BY longhuDate,longhuYingyesuo
Ⅳ sql server怎么判断同一天
datediff(day,'2000-1-1','2000-1-1')
如果以上返回值=0,即表示同一天;
Ⅳ SQL删除同一天多余数据
CREATETABLE#tb(idINT,tbdateDATETIME)
INSERTINTO#tb
VALUES(132,'2015-09-1008:55:55');
INSERTINTO#tb
VALUES(133,'2015-09-1009:55:55');
INSERTINTO#tb
VALUES(134,'2015-09-1010:55:55');
INSERTINTO#tb
VALUES(135,'2015-09-1011:55:55');
INSERTINTO#tb
VALUES(136,'2015-09-1012:55:55');
INSERTINTO#tb
VALUES(137,'2015-09-1108:55:55');
INSERTINTO#tb
VALUES(138,'2015-09-1109:55:55');
INSERTINTO#tb
VALUES(139,'2015-09-1111:55:55');
INSERTINTO#tb
VALUES(140,'2015-09-1112:55:55');
DELETEFROM#tb
WHEREtbdateNOTIN(SELECTa
FROM(SELECTCAST(tbdateASDATE)ASx,
MAX(tbdate)ASa
FROM#tb
GROUPBYCAST(tbdateASDATE)
)m
UNIONALL
SELECTb
FROM(SELECTCAST(tbdateASDATE)ASx,
MIN(tbdate)ASb
FROM#tb
GROUPBYCAST(tbdateASDATE)
)n)
SELECT*
FROM#tb
Ⅵ 用sql语句查询同一天同一人出现次数超过2次的人名
select name,date,count(*) count from users group by date,name having count(*)=max(count)
Ⅶ sql同一个人同一天做的事在两个表怎么查在线等
group by …… having 比如表table中有 人名Name,产品名procts select Name from table group by name,procts having count(*)>2
Ⅷ 请sql语句 查询同一天生日的员工。 要求 查出他们的名字和生日。
SELECT B.*
FROM 员工表 A,员工表 B
Where A.Sbirthday=B.Sbirthday AND A.Sno<>B.Sno
注:员工表为你自己设置的员工表。Sbirthday为生日。只要修改这两个就可以了。
Ⅸ sql中判断同一天,同一月,同一年的工作时间总和
把时间转换成varchar型的,比较前面7位就可以了。
convert(varchar(7),time,126)用这个来比较你的时间time就可以了。
Ⅹ sql如何删除每个员工同一天除了最早和最晚的其他纪录.
楼上的两位请注意这个表中是有多天的记录, 并不只是一天的.
谨慎操作, 先把delete from timerecords改成select查一下是否是想要删除的结果, 然后再delete.
delete from timerecords
where exists (select 'x' from (
select card_id,max(sign_time) sign_time, convert(varchar(10),sign_time,120) current_day from timerecords
group by card_id,convert(varchar(10),sign_time,120)) a where timerecords.card_id = a.card_id and timerecords.sign_time != a.sign_time and convert(varchar(10),timerecords.sign_time,120) = current_day)
and exists (select 'x' from (
select card_id,min(sign_time) sign_time, convert(varchar(10),sign_time,120) current_day from timerecords
group by card_id,convert(varchar(10),sign_time,120)) a where timerecords.card_id = a.card_id and timerecords.sign_time != a.sign_time and convert(varchar(10),timerecords.sign_time,120) = current_day)
