如何在SQL Server数据库中拆分字符串函数呢?
具体方法如下:
以下为引用的内容: CREATE FUNCTION uf_StrSplit '1.1.2.50','.' (@origStr varchar(7000), --待拆分的字符串 @markStr varchar(100)) --拆分标记,如',' RETURNS @splittable table ( str_id varchar(4000) NOT NULL, --编号ID string varchar(2000) NOT NULL --拆分后的字符串 ) AS BEGIN declare @strlen int,@postion int,@start int,@sublen int, @TEMPstr varchar(200),@TEMPid int SELECT @strlen=LEN(@origStr),@start=1,@sublen=0,@postion=1, @TEMPstr='',@TEMPid=0 if(RIGHT(@origStr,1)<>@markStr ) begin set @origStr = @origStr @markStr end WHILE((@postion<=@strlen) and (@postion !=0)) BEGIN IF(CHARINDEX(@markStr,@origStr,@postion)!=0) BEGIN SET @sublen=CHARINDEX(@markStr,@origStr,@postion)-@postion; END ELSE BEGIN SET @sublen=@strlen-@postion 1; END IF(@postion<=@strlen) BEGIN SET @TEMPid=@TEMPid 1; SET @TEMPstr=SUBSTRING(@origStr,@postion,@sublen); INSERT INTO @splittable(str_id,string) values(@TEMPid,@TEMPstr) IF(CHARINDEX(@markStr,@origStr,@postion)!=0) BEGIN SET @postion=CHARINDEX(@markStr,@origStr,@postion) 1 END ELSE BEGIN SET @postion=@postion 1 END END END RETURN END |
例如:select * from uf_StrSplit('1,1,2,50',',')
输出结果:
以下为引用的内容: str_id string 1 1 2 1 3 2 4 50 |
