Here’s a list of the functions and what they do:

• 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 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, then replaces each occurrence with a third character expression. (Unlike the built-in replace T-SQL function, 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.
• GETALLWORDS()—Inserts the words from a string into a table.
• PROPER()—Returns from a character expression a string capitalized as appropriate for proper names.
• RCHARINDEX()—Is similar to the built-in charindex T-SQL function, but the search of which is on the right.
• ARABTOROMAN()—Returns the character Roman number equivalent of a specified numeric expression (from 1 to 3999).
• ROMANTOARAB()—Returns the number equivalent of a specified character Roman number expression (from I to MMMCMXCIX).

Note that my AT, PADL, PADR, CHRTRAN, and PROPER functions are similar to the Oracle PL/SQL INSTR, LPAD, RPAD, TRANSLATE, and INITCAP functions, respectively.

More than 7000 people have already downloaded the functions. I hope you will find them useful as well.
