I've make an own implementation and I want to contribute see the patch attached.
Sintax: strpos(string, substring[, pos]); string -> the master string, can be any type (INTEGER, REAL, BLOB) substring -> to be searched, can be any type (INTEGER, REAL, BLOB) pos [optional default = 1] -> is the number of instance of substring in want, this value can be negative, negative values will be the search in reverse order like (strrchr) Return: The return is the index (1 based) of the char, or 0 if not found, or null if invalid parameters passed Exemples: dirname = substr(filename, 1, strpos(filename, "/", -1) - 1) basename = substr(filename, strpos(filename, "/", -1) + 1) strpos(123231, 2) == 2 strpos(123231, 2, 1) == 2 strpos(123231, 2, -1) == 4 strpos(123231, 2, -2) == 2 strpos(123231, 2, -3) == 0 retrictions: pos need be different of zero ----- Mensagem original ----- De: "Simon Slavin" <slav...@bigfraud.org> Para: "General Discussion of SQLite Database" <sqlite-users@sqlite.org> Enviadas: Quarta-feira, 17 de Março de 2010 11:05:04 Assunto: Re: [sqlite] Why we don't have strpos function? Strings are 16-bit strings which may or may not be Unicode strings, I think. It's hard to work out the position in a string if you don't know what encoding you're using.
