求一个sql，望仁兄们帮助
如何在sql server中将一个ASCII 16进制的字符串装换为对应字符。
Declare @str varchar(50)
set @str='414243313233344B4A'

输出对应字符：ABC1234KJ




[解决办法]

SQL code

Declare @str varchar(50),@result varchar(50)set @str='414243313233344B4A'select   @result=isnull(@result,'')+  char(left(col,1)*16  +case when isnumeric(right(col,1))=0 then ascii(right(col,1))-55 else right(col,1) end  )from(select substring(@str,number*2+1,2) as colfrom master..spt_valueswhere type='P' and number<len(@str)/2) tselect @result as result/**result--------------------------------------------------ABC1234KJ(1 行受影响)**/
