There has been some work into that, it's called XML queries, and I'd
really like to see the providers implementing that. All the
libgda/gda-xql-* files are part of this, but the documentation is very
limited - look into the code.

The idea was to create queries in an XML syntax, and let the providers
translate that XML into their own SQL like syntax. Having the reverse
process would also be nice.

There is also a SQL parser in libgda (in libsql/) which creates its
own tree of nodes, and does not support all the SQL99 features, but
rather a big subset of it.

If you want to go into this, then you are welcome!
