>>Script Language and Platform: Transact-SQL MS SQL Server

Updated:

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.
