Hi, I want to build an internal module for common DB-involved tasks: starting with connection, simple queries and go on to multiple pages of results and connecting tables and so on. We are currently working with MySQL but maybe in the future we'll add use of MSSQL (but it's negligible in comparison with the MYSQL percentage of use). I wonder if to base my functions on the abstract layer of PDO or to use mysql function (means "mysql_connect" and so on). As I see it, mysql functions are more readable and comfortable, but in this case : using MSSQL in the future would affect with new DB module with another implementation. What do would do in such a situation?? I would also like to to hear yours recommendation about ORM projects like Doctrine, Propel and others. Thanks, Miriam
