The error is:

There is already an object named ‘InitCap2′ in the database.

My code is:

CREATE FUNCTION InitCap2( @InputString varchar(4000) )
RETURNS VARCHAR(4000)
AS
BEGIN

DECLARE @Index INT
DECLARE @Char CHAR(1)
DECLARE @PrevChar CHAR(1)
DECLARE @OutputString VARCHAR(255)

SET @OutputString = LOWER(@InputString)
SET @Index = 1

WHILE @Index <= LEN(@InputString)
BEGIN
SET @Char = SUBSTRING(@InputString, @Index, 1)
SET @PrevChar = CASE WHEN @Index = 1 THEN ‘ ‘
ELSE SUBSTRING(@InputString, @Index – 1, 1)
END

IF @PrevChar IN (‘ ‘, ‘;’, ‘:’, ‘!’, ‘?’, ‘,’, ‘.’, ‘_’, ‘-’, ‘/’, ‘&’, ””, ‘(‘)
BEGIN
IF @PrevChar != ”” OR UPPER(@Char) != ‘S’
SET @OutputString = STUFF(@OutputString, @Index, 1, UPPER(@Char))
END

SET @Index = @Index + 1
END

RETURN @OutputString
