sql server 2005 分别用值函数和存储过程拆分字符串成列

Create   PROCEDURE   [ dbo ] . [ label_Add_Bat ]  
@labels   NVARCHAR ( 400 )  --  eg:N'asd,ad,asdoashdo,12313j1,asdasda,asdasd,'
AS
BEGIN

     DECLARE   @temp   TABLE  (col  NVARCHAR ( 100 ))    
     DECLARE   @tlabel   NVARCHAR ( 100 ) 

     INSERT   INTO   @temp   SELECT  col  FROM  split( @labels ,N ' , ' ) 

     declare    cur_temp    cursor    KEYSET   
     for    
     select    col    from    @temp  
      
     open    cur_temp   

     FETCH     NEXT     FROM    cur_temp    INTO     @tlabel   
     
     while  ( @@FETCH_STATUS = 0 )   
     begin    
          IF ( EXISTS ( SELECT  label_Id  FROM  label  WHERE  label_Caption = @tlabel ))
             BEGIN
                  UPDATE  label  SET  label_Num  =  label_Num  +   1   WHERE  label_Caption = @tlabel
             END
          ELSE
              BEGIN
                  INSERT   INTO   [ label ]  ( [ label_Caption ] )  VALUES  ( @tlabel )
              END
         FETCH     NEXT     FROM    cur_temp    INTO     @tlabel   
     end    
    
     close    cur_temp   
    
     DEALLOCATE    cur_temp   
END

 

表值函数split:

 

CREATE   function   [ dbo ] . [ split ] ( @c   varchar ( max ), @split   varchar ( 2 )) 
returns   @t   table (col  varchar ( 20 )) 
as  
BEGIN
     DECLARE   @item   NVARCHAR ( 20 )
    
     -- params
     while ( charindex ( @split , @c ) > 0 ) 
     begin  
         SET   @item = substring ( @c , 1 , charindex ( @split , @c ) - 1 )
        
         /* check is empty */
         IF ( RTRIM ( LTRIM ( @item )) != '' )
         BEGIN
             insert   @t (col)  values  ( @item )              
         END
        
         set   @c   =   stuff ( @c , 1 , charindex ( @split , @c ), '' )        
     end  
    
     -- one param    
     IF ( RTRIM ( LTRIM ( @c )) != '' )
     BEGIN
         insert   @t (col)  values  ( @c ) 
     END
    
    
     return  
end
