sql create function error code 1064 - mysql

Question

I need to create a function that I found here: http://vyaskn.tripod.com/code/propercase.txt It converts text to "ProperCase," first letter of every word to uppercase.
CREATE FUNCTION PROPERCASE
(
-- The string to be converted to proper case
#input VARCHAR( 8000 )
)
-- This function returns the proper case string of varchar type
RETURNS VARCHAR( 8000 )
AS
BEGIN
IF #input IS NULL
BEGIN
-- Just return NULL if input string is NULL
RETURN NULL
END
-- Character variable declarations
DECLARE #output VARCHAR( 8000 )
-- Integer variable declarations
DECLARE #ctr INT, #len INT, #found_at INT
-- Constant declarations
DECLARE #LOWER_CASE_a INT, #LOWER_CASE_z INT, #Delimiter CHAR(3), #UPPER_CASE_A INT, #UPPER_CASE_Z INT
-- Variable/Constant initializations
SET #ctr = 1
SET #len = LEN(#input)
SET #output = ''
SET #LOWER_CASE_a = 97
SET #LOWER_CASE_z = 122
SET #Delimiter = ' ,-'
SET #UPPER_CASE_A = 65
SET #UPPER_CASE_Z = 90
WHILE #ctr <= #len
BEGIN
-- This loop will take care of reccuring white spaces
WHILE CHARINDEX(SUBSTRING(#input,#ctr,1), #Delimiter) > 0
BEGIN
SET #output = #output + SUBSTRING(#input,#ctr,1)
SET #ctr = #ctr + 1
END
IF ASCII(SUBSTRING(#input,#ctr,1)) BETWEEN #LOWER_CASE_a AND #LOWER_CASE_z
BEGIN
-- Converting the first character to upper case
SET #output = #output + UPPER(SUBSTRING(#input,#ctr,1))
END
ELSE
BEGIN
SET #output = #output + SUBSTRING(#input,#ctr,1)
END
SET #ctr = #ctr + 1
WHILE CHARINDEX(SUBSTRING(#input,#ctr,1), #Delimiter) = 0 AND (#ctr <= #len)
BEGIN
IF ASCII(SUBSTRING(#input,#ctr,1)) BETWEEN #UPPER_CASE_A AND #UPPER_CASE_Z
BEGIN
SET #output = #output + LOWER(SUBSTRING(#input,#ctr,1))
END
ELSE
BEGIN
SET #output = #output + SUBSTRING(#input,#ctr,1)
END
SET #ctr = #ctr + 1
END
END
RETURN #output
END
I need a function to do that, but it's giving me error...

You are using MySQL, but the syntax you have is for SQL Server. Please read the documentation about MySQL's syntax and convert your procedure to use that syntax. The major constructs are the same, but the syntax is a little different. Here are some things to start with:
Local variables never start with #.
IF is condition followed by THEN followed by any number of lines of code, followed by END IF. The BEGIN...END construct is not used for IF statements in MySQL.
The functions are different. You won't use CHARINDEX but instead INSTR.
Here's the relevant MySQL documentation: http://dev.mysql.com/doc/refman/5.5/en/stored-routines-syntax.html and http://dev.mysql.com/doc/refman/5.5/en/sql-syntax-compound-statements.html.
