Pinal, you should also change the @Output declaration to match the input size:
DECLARE @OutputString VARCHAR(4000) –was (255)

or long strings will return a blank!

CREATE FUNCTION ChangeTitleCase (@InputString VARCHAR(4000) )
RETURNS VARCHAR(4000)
AS
BEGIN
DECLARE @Index INT
DECLARE @Char CHAR(1)
DECLARE @OutputString VARCHAR(255)
SET @OutputString = LOWER(@InputString)
SET @Index = 2
SET @OutputString =
STUFF(@OutputString, 1, 1,UPPER(SUBSTRING(@InputString,1,1)))
WHILE @Index <= LEN(@InputString)
BEGIN
SET @Char = SUBSTRING(@InputString, @Index, 1)
IF @Char IN (' ', ';', ':', '!', '?', ',', '.', '_', '-', '/', '&','''','(')
IF @Index + 1 <= LEN(@InputString)
BEGIN
IF @Char != ''''
OR
UPPER(SUBSTRING(@InputString, @Index + 1, 1)) != 'S'
SET @OutputString =
STUFF(@OutputString, @Index + 1, 1,UPPER(SUBSTRING(@InputString, @Index + 1, 1)))
END
SET @Index = @Index + 1
END
RETURN ISNULL(@OutputString,'')

I have only one remark here. I think you should declare @OutputString as VARCHAR(4000) as well. Otherwise you will loose string content over 255 chars.

i have a question regarding this udf. English language specific the words like and, or, the are not marked as init cap, how can we handle it?

thanks in advance:

It’s a shame this forum doesn’t honor any type of formatting… the function looks quite nice when properly formatted. I’m trying to us non-breaking spaces but, if that doesn’t work, I’ll just post it flat…

CREATE FUNCTION dbo.InitialCap(@String VARCHAR(8000))
/***************************************************************************************************
Purpose:
Capitalize any lower case alpha character which follows any non alpha character or single quote.

– Redaction for personal use and added documentation.
– Add no-cap single-quote by single-quote to the filter.
