I am running on SQL Server 2008 R2 and we have a requirement here whereby I need to create replace certain English characters to locale language characters used previously in legacy system.
For this, I would probably use the replace function in T-SQL, but in my practice, we are replacing character by character for example
'ASkjDe'
A=char(XX)
S=char(XX)
k=char(XX)
j=char(XX)
D=char(XX)
e=char(XX)
Now, I want to avoid using nested replace which means I have to do 32 character check. Is there such a function which I can pass it list of values?
We already have a function in place which does the replacing but its very slow and we are hoping that replace function would do a better job. Below is the current function we are using
CREATE FUNCTION [dbo].[ArabicToString] (@inString VARCHAR(MAX))
RETURNS NVARCHAR(MAX)
AS

DECLARE @Vchar char(1), @Result NVARCHAR(MAX), @Flag BIT, @Position INT, @StrLength INT, @LChar CHAR, @HChar NCHAR
SET @Result = ''
SET @Position = 1
SET @StrLength = DATALENGTH(@inString) -- string length not going to change
SET @VChar = SUBSTRING(@inString, @Position, 1)
if ASCII(@Vchar) > 189 and ASCII(@Vchar) < 255
RETURN Rtrim(Ltrim(@inString))
WHILE (@Position <= @StrLength) -- leave loop if bad character found
BEGIN
-- Reset holders
SET @LChar = SUBSTRING(@inString, @Position, 1)
Set @HChar = ''

If someone can suggest a different approach, something even other than the replace function or the above approach we currently using I would appreciate it.
