剥离不需要的字符从一个字符串在MS SQL

如何将保留逗号输出

select @cleanline=line from #tbl 

    While PatIndex('%[^A-Z,a-z,0-9]%', @cleanline) > 0   
    Set @cleanline = Stuff(@cleanline, PatIndex('%[^A-Z,a-z,0-9]%', @cleanline), 1, '') 

    print @cleanline

您的代码** **不保留逗号。你问怎么没有？ – 2011-05-09 13:38:43

对不起，也许我没有让自己清楚 - 我需要保持az 0-9和逗号 – Rob 2011-05-09 13:43:02

@Rob - 那么如果我尝试'声明@cleanline varchar（max）='一，二，三，$''并运行它您的代码逗号保留。 – 2011-05-09 13:44:24

~~变化 %[^A-Z,a-z,0-9]%到 %[^A-Z0-9]%或 %[^A-Za-z0-9]%~~

~~默认情况下，SQL Server isn' t情况敏感的，你不需要在 pattern-match strings~~

编辑逗号：原来有没有逗号在数据...

select @cleanline = line from #tbl 
set @tokeeppattern = '%[^A-Z,a-z0-9' + CHAR(9) + ']%' 


While PatIndex(@tokeeppattern, @cleanline) > 0   
Set @cleanline = Stuff(@cleanline, PatIndex(@tokeeppattern, @cleanline), 1, '') 

print @cleanline
