教你在SQL Server数据库中拆分字符串函数

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IDstring varchar(2000) NOT NULL --拆分后的字符串)AS BEGINdeclare @strlen int,@postion int,@start int,@sublen int,@TEMPstr varchar(200),@TEMPid intSELECT @strlen=LEN(@origStr),@start=1,@sublen=0,@postion=1,@TEMPstr='',@TEMPid=0if(RIGHT(@origStr,1)<>@markStr )beginset @origStr = @origStr + @markStrendWHILE((@postion<=@strlen) and (@postion !=0))BEGINIF(CHARINDEX(@markStr,@origStr,@postion)!=0)BEGINSET @sublen=CHARINDEX(@markStr,@origStr,@postion)-@postion; ENDELSEBEGINSET @sublen=@strlen-@postion+1;ENDIF(@postion<=@strlen)BEGINSET @TEMPid=@TEMPid+1;SET @TEMPstr=SUBSTRING(@origStr,@postion,@sublen);INSERT INTO @splittable(str_id,string) values(@TEMPid,@TEMPstr)IF(CHARINDEX(@markStr,@origStr,@postion)!=0)BEGINSET @postion=CHARINDEX(@markStr,@origStr,@postion)+1ENDELSEBEGINSET @postion=@postion+1ENDENDENDRETURNEND

例如：select * from uf_StrSplit('1，1，2，50','，')

输出结果：

str_id string1 12 13 24 50
