Oh, if only the DBMS vendors could agree on ONE PLAIN FLAVOR OF SQL it would make my life sooo much easier...

I think this will happen about the same time Microsoft voluntarily open sources and GPLs Windows along with porting Office to Linux.

It is too bad though. Standard SQL would make life a lot easier for us all.

In the mean time maybe you can keep all the database specific code in one module, and dynamically require that library depending on which DBD you are using. So that way you should really be able to utilize the power of each database, but still maintain a some-what portable app. Then you can create a database module for each database the app will be using.
