删除SQL中的特殊字符

 I have to remove the special characters from the selected string.

例如：我有字符串'a & b'或'a & b'。我如何删除特殊字符并将这些字符串连接成'ab'。删除SQL中的特殊字符

请任何人都可以告诉我。

SELECT @id= (UPPER(SUBSTRING(@a,1,2)))+(UPPER(SUBSTRING((SELECT table.column2 FROM tablename WHERE tablename.column1 = @b),1,2))) + RIGHT('000000000' + CAST(@count as varchar(10)), 6)

** **刚刚'＆'和空白或任何非字母字符？ –

包括任何非aplha字符 – Raj

的function是迄今为止最好的选择，如果你必须这样做内联，你可以递归CTE内更换和使用，作为基表;

select 1 as id, 
     'qw2££!"£$%^&**(' as F into #TESTTABLE 
insert #TESTTABLE 
values (2, 'xxx'), 
     (3, ''), 
     (4,'$'), 
     (5,'qq""ee$$') 

;with cte(id, stripped) as (
    select id, cast(F as varchar(1024)) from #TESTTABLE 
    union all 
    select id, cast(stuff(stripped, patindex('%[^a-z]%', stripped), 1, '') as varchar(1024)) 
    from cte 
    where patindex('%[^a-z]%', stripped) > 0 
) 
select * from cte 
    where patindex('%[^a-z]%', stripped) = 0 
order by id

结果：

>>id stripped 
>>1 qw 
>>2 xxx 
>>3 
>>4 
>>5 qqee

感谢您的重播...我有一个答案..链接ü给它它可以帮助我... – Raj

Declare @temp varchar(30) 
Set @temp = 'A & B' 
While PatIndex('%[^a-z]%', @Temp) > 0 
Set @Temp = Stuff(@Temp, PatIndex('%[^a-z]%', @Temp), 1, '') 

SELECT @id= (UPPER(SUBSTRING(@Temp,1,2)))+(UPPER(SUBSTRING((SELECT table.column2 FROM tablename WHERE tablename.column1 = @b),1,2))) + RIGHT('000000000' + CAST(@count as varchar(10)), 6)

DECLARE @str VARCHAR(400) 
DECLARE @expres VARCHAR(50) = '%[~,@,#,$,%,&,*,(,),.,!]%' 
    SET @str = 'a&b' 
    WHILE PATINDEX(@expres, @str) > 0 
     SET @str = Replace(REPLACE(@str, SUBSTRING(@str, PATINDEX(@expres, @str), 1),''),'-',' ') 

    SELECT @str
