问一个sql解决解析的问题[希望是通过纯sql语句解决]

有2个表表A------------------------字段名/AUTH/AUTHNAME/ 12 /前锋/ 7 /守门/ 244/教练------------------------表B------------------------字段名/AUTHG/AUTHGNAME/ 1 /12,7/ 2 /244/ 3 /12,7,244------------------------希望得到的查询结果1/前锋,守门2/教练3/前锋,守门,教练等于是把数字解析成文字,谢谢

先建立一个和表B一样结构的表C，然后用游标实现

declare @source varchar(20)

declare @desc varchar(20)

declare @lstr varchar(20)

declare @rstr varchar(20)

declare @memo varchar(20)

declare @id int

declare @k int

declare cs1 cursor for

select AUTHG,AUTHGNAME from 表B

truncate table 表C

open cs1

fetch next from cs1 into @id,@source

while @@FETCH_STATUS = 0

begin

set @source=@source+','

set @desc=''

set @rstr=@source

set @k=charindex(',',@rstr)

while @k>0

begin

set @lstr=substring(@rstr,1,charindex(',',@rstr)-1)

set @rstr=substring(@rstr,charindex(',',@rstr)+1,len(@rstr)-charindex(',',@rstr))

select @memo=AUTHNAME from 表A where AUTH=@lstr

set @desc=@desc+@memo+','

set @k=charindex(',',@rstr)

end

insert into 表C values(@id,left(@desc,len(@desc)-1))

fetch next from cs1 into @id,@source

end

close cs1

deallocate cs1

select * from 表C
