To remove or replace multiple special character from string using sql queries.

In FN_REMOVE_SPECIAL_CHARACTER] we make use of WITH clause CTE to store the resultset of all special character in one row table.To remove unwanted special characters,we pass string input values and apply string's replace funtion having special character match values from CTE table .


CREATE FUNCTION [FN_REMOVE_SPECIAL_CHARACTER] (  
 @INPUT_STRING varchar(300))
RETURNS VARCHAR(300)
AS 
BEGIN
 
--declare @testString varchar(100),
DECLARE @NEWSTRING VARCHAR(100) 
-- set @teststring = '@san?poojari(darsh)'
 SET @NEWSTRING = @INPUT_STRING ; 
With SPECIAL_CHARACTER as
(
SELECT '>' as item
UNION ALL 
SELECT '<' as item
UNION ALL 
SELECT '(' as item
UNION ALL 
SELECT ')' as item
UNION ALL 
SELECT '!' as item
UNION ALL 
SELECT '?' as item
UNION ALL 
SELECT '@' as item
UNION ALL 
SELECT '*' as item
UNION ALL 
SELECT '%' as item
UNION ALL 
SELECT '$' as item
 )
SELECT @NEWSTRING = Replace(@NEWSTRING, ITEM, '') FROM SPECIAL_CHARACTER  
return @NEWSTRING 
END
select dbo.[FN_REMOVE_SPECIAL_CHARACTER] ('@s()antosh')
