Hi,

> By the way, how do you set the dialect you want to use?

I haven't tried this myself, but property "sql_dialect" should work.
If you use URL-encoded params, try "?...&sql_dialect=3".

General contract is that you can use any of the isc_dpb_XXXX DPB
constants defined in gds.h (or org.firebirdsql.gds.GDS class) as
connection parameters.
