I want to do write a script that stores/reads data in/from a database. Initially, I will use MySQL/Apache/Linux for development.

Eventually, I need to be able to port it to different OSs/databases.

I was thinking the best way to do this would be:

• create a module that makes the database calls using the relevant DBI/DBD module
• amend this common module for each database that I port to.

Rather than use a 'chainsaw' approach, I wanted to be able to define fields, tables etc using a common notation, and then translate it to the nearest equivalent for each DB used. Ie, I'm looking for a kind of 'lowest common denominator' of SQL and var types that I can safely use. Has anyone else done anything similar and, if so, what did you use for the following:

• SQL functions you can trust - SELECT, INSERT, etc...
• datatypes to use - eg, TINYINT, VARCHAR(n), etc...
• transactions, data integrity etc?!?

Or am I hoping for too much in being able to write 'cross DB' scripts?

cLive ;-)

I thought it worth while asking now (before I end up that creek without a paddle :) just in case I'm missing something...
