SQL 2008 - 날짜가 이미 존재하지 않으면 표에 삽입하십시오.

Question

안녕하세요. 다음 스크립트를 삽입하여 작업을 삽입하려면 어떻게해야합니까? 먼저 표가 존재하는 경우 표가 존재하는지 확인한 다음 표에만 삽입하십시오. 표가 아직 표에없는 경우 표에 삽입하고 싶습니다. 그렇지 않으면 테이블을 선택하십시오.

DECLARE @date1 datetime 
DECLARE @date2 datetime 
DECLARE @dailyEnd1 varchar(12) 
DECLARE @dailyEnd2 varchar(12) 
DECLARE @column varchar(100) 
DECLARE @Script varchar(8000) 
SET @date1 = '09 jan 2012' 
SET @date2 = '15 jan 2012' 

SET @dailyEnd1 = @date1 
SET @dailyEnd2 = @date2 

IF OBJECT_ID('tempdb..#table1') is not null 

    BEGIN 
     IF NOT EXIST (SELECT MinDate, MaxDate FROM #table1 
      WHERE MinDate = '02 Jan 2012' AND MaxDate = '08 jan 2012' 
      GROUP BY MinDate, MaxDate) 
      BEGIN 
       INSERT INTO #table1 (MinDate, MaxDate, [Week], OutletID, OutletName, Transactions, Spend) 
       SELECT min(dailyEnd-1), max(dailyEnd-1), 
       convert(varchar(12),Min(dailyEnd-1), 104)+'-'+convert(varchar(12),MAX(dailyEnd-1),104), 
       OutletID, OutletName, 
       sum(Transactions), sum(Sales) 
       FROM #table2 (NOLOCK) 
       WHERE dailyEnd-1 >= @dailyEnd1 
       AND dailyEND-1 <= @dailyEnd2 
       GROUP BY OutletID, OutletName 
      END 
    END 

ELSE 
    BEGIN 

    SELECT min(dailyEnd-1) as MinDate, max(dailyEnd-1) as MaxDate, 
    convert(varchar(12),Min(dailyEnd-1), 104)+'-'+convert(varchar(12),MAX(dailyEnd-1),104) as [Week], OutletID, OutletName, sum(Transactions) as Transactions, sum(Sales) as Spend 
    INTO #table1 
    FROM #table2 (NOLOCK) 
    WHERE dailyEnd-1 >= @dailyEnd1 
    AND dailyEND-1 <= @dailyEnd2 
    GROUP BY OutletID, OutletName 

    END

은 INSERT 후 아래 WHERE에 NOT EXISTS 절을 이동

.

의미, 삽입 할 경우에만 날짜 범위에 대해 NOT EXISTS입니다.
