User-Defined string Functions Transact-SQL MS SQL Server
November 21, 2005
>>Script Language and Platform: Transact-SQL MS SQL Server
I would like to offer you 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.
- GETALLWORDS(): Inserts the words from a string into the table.
- 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 5000 people have already downloaded my functions. I hope you will find them useful as well.
