sql同一天
Ⅰ sql查詢語句 如何同一天同一人的記錄合並到一起
select distinct intime,user from TableName
或者
Select intime,user from TableName group by intime,user
Ⅱ sql語句實現考勤報表,sql語句怎樣實現員工同一天只有兩次考勤
兩次考勤:select 員工ID,TRUNC(TIME,'d') FROM 考勤表 group by 員工ID,TRUNC(TIME,'d')
having count(*)=2;
漏打:select 員工ID,TRUNC(TIME,'d') FROM 考勤表 group by 員工ID,TRUNC(TIME,'d')
having count(*)<2;
Ⅲ MS-SQL查詢:顯示同一天內多行數據的總和
首先你的意思 其實是分組求和的意思,對日期進行分組,對金額進行求和,那麼這樣就存在一個問題:你是想求和之後每一天 都只顯示一條求和後的數據是吧,那麼你的第二列 就不應該顯示,因為同一天里的多條數據裡面,第二列是不同的,不能進行分組。那麼排除第二列後就好辦了:
SELECT longhuDate ,longhuYingyesuo ,SUM(longhuBuy) ,SUM(longhuSell) ,SUM(longhuOnly)FROM [stormLonghubang]
where [longhuYingyesuo]='國泰君安證券上海福山路營業部'
GROUP BY longhuDate,longhuYingyesuo
Ⅳ sql server怎麼判斷同一天
datediff(day,'2000-1-1','2000-1-1')
如果以上返回值=0,即表示同一天;
Ⅳ SQL刪除同一天多餘數據
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語句查詢同一天同一人出現次數超過2次的人名
select name,date,count(*) count from users group by date,name having count(*)=max(count)
Ⅶ sql同一個人同一天做的事在兩個表怎麼查在線等
group by …… having 比如表table中有 人名Name,產品名procts select Name from table group by name,procts having count(*)>2
Ⅷ 請sql語句 查詢同一天生日的員工。 要求 查出他們的名字和生日。
SELECT B.*
FROM 員工表 A,員工表 B
Where A.Sbirthday=B.Sbirthday AND A.Sno<>B.Sno
註:員工表為你自己設置的員工表。Sbirthday為生日。只要修改這兩個就可以了。
Ⅸ sql中判斷同一天,同一月,同一年的工作時間總和
把時間轉換成varchar型的,比較前面7位就可以了。
convert(varchar(7),time,126)用這個來比較你的時間time就可以了。
Ⅹ sql如何刪除每個員工同一天除了最早和最晚的其他紀錄.
樓上的兩位請注意這個表中是有多天的記錄, 並不只是一天的.
謹慎操作, 先把delete from timerecords改成select查一下是否是想要刪除的結果, 然後再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)
