PDO (was: SQLite API deficiency)

Hi, > I'm currently in DB API mode (working on PDO), I know PDO is slated to be _the_ db-abstraction module from 5.x (5.1?) onwards (which would replace dbx, but that's fine by me: PDO seems to work more or less the same but with a more OO-ish api), but I was wondering if these names bear any relation to the Python DB-API and the Python Database Objects, or if that is more of a coincidence? Also, will there be an complementary SQL-abstraction package for SQL-dialect differences (such as UPPER(value) vs. UCASE(value), or differences in TOP/LIMIT/OFFSET usage)? I have a preliminary package ready (in php-source-code, not c) that is coupled to an OO-ish api for dbx, but is easily rewritable to a more generic version. Cheerio, Marc.
