Ladies and Gentlemen,

I am pleased to offer, free of charge, the following string functions
Transact-SQL:

AT():  Returns the beginning numeric position of the nth occurrence of a
character expression within another character expression, counting from the
leftmost character.
RAT(): Returns the numeric position of the last (rightmost) occurrence of a
character string within another character string.
OCCURS():  Returns the number of times a character expression occurs within
another character expression (including overlaps).
OCCURS2(): Returns the number of times a character expression occurs within
another character expression (excluding overlaps). 
PADL(): Returns a string from an expression, padded with spaces or
characters to a specified length on the left side.
PADR(): Returns a string from an expression, padded with spaces or
characters to a specified length on the right side.
PADC(): Returns a string from an expression, padded with spaces or
characters to a specified length on the both sides.
CHRTRAN():  Replaces each character in a character expression that matches a
character in a second character expression with the corresponding character
in a third  character expression.
STRTRAN():  Searches a character expression for occurrences of a second
character expression, and then replaces each occurrence with a third
character expression. Unlike a built-in function Replace, STRTRAN has three
additional parameters.
STRFILTER(): Removes all characters from a string except those specified.
GETWORDCOUNT(): Counts the words in a string.
GETWORDNUM():   Returns a specified word from a string.
PROPER(): Returns from a character expression a string capitalized as
appropriate for proper names.
RCHARINDEX():  Similar to the Transact-SQL function Charindex, with a Right
search.
ARABTOROMAN(): Returns the character Roman numeral equivalent of a specified
numeric expression (from 1 to 3999).
ROMANTOARAB(): Returns the number equivalent of a specified character Roman
numeral expression (from I to MMMCMXCIX).

AT, PADL, PADR, CHRTRAN, PROPER:  Similar to the Oracle functions PL/SQL
INSTR, LPAD, RPAD, TRANSLATE, INITCAP.

More than 4000 people have already downloaded my functions.  I hope you will
find them useful as well.

BTW MS SQL 2000 SP 4 has bug
-- I did run this example and validated the erroneous result
declare @n nvarchar(4000)
set @n = replicate(N'z',3999)+N'i'
select right(replace(@n, N'i', N'B'),1) -- display i but this is incorrect
result, correct result is B
