Question

문자열에서 여러 ","위치 '를,'얻으려면 .

내 출력은 다음과 같이해야한다 : 당신이 목록을 쉼표로 구분에서 당신의 ID 값을 분할하려고하는 것처럼

Answer 1

다음을 반환합니다

select i.ID 
     ,ItemNumber 
     ,Item as IDSplit 
from Input i 
    cross apply dbo.DelimitedSplit8K(i.ID,',') s; 

출력물을 직접 출력 해보십시오.

Create table #Table (rowNo int identity(1,1), ID varchar(100)) 
insert into #Table values('32132') 
insert into #Table values('32132,32132') 
insert into #Table values('32132,32132,6456,654,645') 

declare @TableRow int = (select count(*) from #Table),@Tableloop int = 1 
while(@Tableloop <= @TableRow) 
begin 
    Declare @var varchar(100) ; 
    SET @var = (select ID from #Table where rowNo=@Tableloop) 
    declare @count int = (select len(@var) - len(replace(@var, ',', ''))) 
    declare @loop int = 1; 
    declare @location int = 0; 
    print 'Row' + cast(@Tableloop as varchar(5)) 
    while (@loop <= @count) 
    begin 
     SET @location = (select charindex(',',@var,@location)) 
     print cast(@loop as varchar(5)) + ' Comma at ' + cast(@location as varchar(5)) 
     SET @location = @location +1 
     SET @loop = @loop + 1; 
    end 

    SET @Tableloop = @Tableloop + 1; 
END 
drop table #Table 

이렇게하면 임시 테이블에 넣고 표시하기 만하면됩니다.

Answer 2

것 같습니다. 이 경우 쉼표로 구분 된 목록을 행으로 분할하는 테이블 반환 함수를 만드는 것이 좋습니다.

다음과 같은 사용하여이 달성하기 위해 아래 제프 MODEN의 기능을 사용할 수 있습니다

:
