Sql基本操作

1. 语句创建表

经常用语句操作数据库，比如创建表，在此写下常用的语句，备忘。

在语句中创建主键，并自增长1：

Create table ObjectInfo
(
ID INT not null primary key identity(1,1),
ObjName varchar(100),
ObjDesc varchar(100),
OStatus varchar(5),
ActionDate date,
OrderID int ,
OType varchar(10)

)

2. 创建方法：标量值函数

CREATE FUNCTION [dbo].[fGetAbnormalCount](@staffId INT, @startDate date, @endDate date, @type int)
RETURNS INT
BEGIN
DECLARE @COUNT INT
IF @type = 1
BEGIN 
  SET @COUNT = (SELECT COUNT(1) from  HMP_STAFF_WORKTIME where ID IN (
SELECT ID FROM HMP_STAFF_WORKTIME WHERE StaffID = @staffId and WorkDate BETWEEN @startDate AND @endDate
 and CheckTime in(select MIN(CheckTime) from HMP_STAFF_WORKTIME group by WorkDate ))
 AND CheckTime > (SELECT StartTimeAM FROM HMP_WORKTIME WHERE WorkDate BETWEEN EnableDate AND DisAbleDate)
      AND dbo.fJudgeWorkDay(@staffId, WorkDate) = 1 )
  +(SELECT COUNT(1) from  HMP_STAFF_WORKTIME where ID IN (
SELECT ID FROM HMP_STAFF_WORKTIME WHERE StaffID = @staffId and WorkDate BETWEEN @startDate AND @endDate
 and CheckTime in(select MIN(CheckTime) from HMP_STAFF_WORKTIME group by WorkDate ) )
 AND CheckTime > (SELECT StartTimeAM FROM HMP_WORKTIME WHERE WorkDate BETWEEN EnableDate AND DisAbleDate)
      AND dbo.fJudgeWorkDay(@staffId, WorkDate) = 2)
      + (SELECT COUNT(1) from  HMP_STAFF_WORKTIME where ID IN (
SELECT ID FROM HMP_STAFF_WORKTIME WHERE StaffID = @staffId and WorkDate BETWEEN @startDate AND @endDate
 and CheckTime in(select MIN(CheckTime) from HMP_STAFF_WORKTIME group by WorkDate ) )
 AND CheckTime > (SELECT StartTimePM FROM HMP_WORKTIME WHERE WorkDate BETWEEN EnableDate AND DisAbleDate)
      AND dbo.fJudgeWorkDay(@staffId, WorkDate)= 3)
END
ELSE IF @type = 2 --早退
BEGIN
  SET @COUNT = (SELECT COUNT(1) from  HMP_STAFF_WORKTIME where ID IN (
SELECT ID FROM HMP_STAFF_WORKTIME WHERE StaffID = @staffId and WorkDate BETWEEN @startDate AND @endDate
 and CheckTime in(select MAX(CheckTime) from HMP_STAFF_WORKTIME group by WorkDate ) )
 AND CheckTime < (SELECT EndTimeAM FROM HMP_WORKTIME WHERE WorkDate BETWEEN EnableDate AND DisAbleDate)
      AND dbo.fJudgeWorkDay(@staffId, WorkDate) = 2)
      +(SELECT COUNT(1) from  HMP_STAFF_WORKTIME where ID IN (
SELECT ID FROM HMP_STAFF_WORKTIME WHERE StaffID = @staffId and WorkDate BETWEEN @startDate AND @endDate
 and CheckTime in(select MAX(CheckTime) from HMP_STAFF_WORKTIME group by WorkDate ) )
 AND CheckTime < (SELECT EndTimePM FROM HMP_WORKTIME WHERE WorkDate BETWEEN EnableDate AND DisAbleDate)
  AND dbo.fJudgeWorkDay(@staffId, WorkDate) = 1)
      +
        (SELECT COUNT(1) from  HMP_STAFF_WORKTIME where ID IN (
SELECT ID FROM HMP_STAFF_WORKTIME WHERE StaffID = @staffId and WorkDate BETWEEN @startDate AND @endDate
 and CheckTime in(select MAX(CheckTime) from HMP_STAFF_WORKTIME group by WorkDate ) )
 AND CheckTime < (SELECT EndTimePM FROM HMP_WORKTIME WHERE WorkDate BETWEEN EnableDate AND DisAbleDate)
 AND dbo.fJudgeWorkDay(@staffId, WorkDate) = 3)
END
ELSE --旷工
BEGIN 
DECLARE @NUM INT, @DATE DATE, @DAYCOUNT INT
SET @DATE = @STARTDATE
SET @NUM = 0
WHILE @DATE <= @ENDDATE
BEGIN
  SET @DAYCOUNT =( SELECT COUNT(1) FROM HMP_STAFF_WORKTIME WHERE @StaffID = @staffId and WorkDate =@DATE
  AND  dbo.fJudgeWorkDay(@staffId, WorkDate) IN(1,2,3))
  IF @DAYCOUNT = 0
  BEGIN  SET @NUM = @NUM +1 END
  
  SET @DATE = DATEADD(DAY, 1,@DATE)
END
SET @COUNT = @NUM
--  SET @COUNT = (SELECT DATEDIFF([DAY], @startDate,@endDate)-
--(select  COUNT( distinct WorkDate) from HMP_STAFF_WORKTIME where StaffID = 
--@staffId and WorkDate between @startDate and @endDate))
END
RETURN @COUNT
END

　调用：

SELECT  [dbo].[fGetAbnormalCount](123, '20130803','20140803' , 1)

　　表值函数：

  1 CREATE FUNCTION [dbo].[fGetAttenDetailByID](@staffID INT, @startDate date, @endDate date)
  2 RETURNS TABLE
  3 RETURN (SELECT ID, StaffNum, StaffName, (SELECT CAMPUSNAME FROM HMP_CAMPUS_INFO WHERE ID = EntryCampus)EntryCampus, (SELECT CAMPUSNAME FROM HMP_CAMPUS_INFO WHERE ID = WORKCAMPUS)WorkCampus, (select DepartName from HMP_DEPARTMENT_INFO where ID = DepartmentID)DepartmentID,
  4 (select ParamValue from HMP_PARAM where ID = Post) Post, (select COUNT(1) from ((SELECT WorkDate FROM HMP_STAFF_WORKTIME WHERE StaffID = HMP_STAFF_INFO.ID AND WORKDATE BETWEEN @startDate AND @enddate GROUP BY WorkDate) )A) 'attendance',
  5  (SELECT COUNT(1) FROM HMP_DUTY_ARRANGE WHERE STAFFID = HMP_STAFF_INFO.ID AND DUTYDATE BETWEEN @startDate AND @enddate) 'onduty',
  6  (SELECT dbo.fGetAbnormalCount(@staffID, @startDate, @ENDDATE, 1)) 'Late',
  7  (SELECT dbo.fGetAbnormalCount(@staffID, @startDate, @ENDDATE, 2)) 'EarlyLeave',
  8  (SELECT dbo.fGetAbnormalCount(@staffID, @startDate, @ENDDATE, 3)) 'WorkAbsence',
  9 (SELECT COUNT(1) FROM HMP_UNREGISTER WHERE ADDER = @STAFFID AND TEMPLATEID = 1 AND UNREGDATE BETWEEN @startDate AND @enddate AND STATUS = 1) 'PublicLackCheck',
 10 (SELECT COUNT(1) FROM HMP_UNREGISTER WHERE ADDER = @STAFFID AND TEMPLATEID = 2 AND UNREGDATE BETWEEN @startDate AND @enddate AND STATUS = 1)  'privateLackCheck',
 11  (select cast(COUNT(1) /2.0 as numeric(5,1)) from HMP_IRREGULAR_DATE where  StaffID = HMP_STAFF_INFO.ID AND ISWORK = 0 AND IrregularDate BETWEEN @startDate AND @enddate) 'Vocation',

 13  FROM HMP_STAFF_INFO WHERE ID = @staffID)
 14 　为表赋值：
