贴上同事写的一个字符串分割函数

 1 CREATE FUNCTION FN_GetFormat_String
 2 (
 3     @Format NVARCHAR(10),
 4     @String VARCHAR(8000)
 5 )  
 6 RETURNS @TEMP TABLE(iRow INT IDENTITY(1,1),vReturn VARCHAR(1000))  
 7 AS  
 8 BEGIN  
 9 /*  
10 CREATE TIME:2009-07-17 15:23  
11 BY:  
12 说明:根据分隔参数[@Format],将[@String]以参数分隔开,返回表  
13 */  
14 DECLARE @I INT  
15 SET @I=CHARINDEX(@Format,@String)  
16   
17 WHILE @I >0  
18 BEGIN  
19  INSERT INTO @TEMP(vReturn) SELECT SUBSTRING(@String,1,@I-1)  
20  SET @String=SUBSTRING(@String,@I+1,LEN(@String))  
21  SET @I=CHARINDEX(@Format,@String)  
22 END  
23 IF LEN(@String) >0 INSERT INTO @TEMP(vReturn) SELECT @String  
24 RETURN  
25 END
