What you're asking for is nearly impossible to provide. Portability is the biggest--of several--problems with SQL.

There is an ANSI standard for SQL that all SQLDBs must comply with to to earn the name, but this standard is so lowest-common-denominator, that sticking to it makes your application very hard, very inefficient, or both. Or even impossible within the constraints of practicality.

And even if you stick rigidly to the ANSI standard, the exact same syntax can produce wildly differing results on different complient platforms. Eg. Think ANSI Standard SQL Is Fully Portable Between Databases? Think Again..
