> But, f.y.i., Fire has two "SQL Dialects" (and it's not a standard thing at all). It has to do with SQL language implementation changes waaaaay back in time, when Firebird's distant ancestor, InterBase 6, introduced 64-bit numbers and standard date and time types. Old databases from IB 5 and older speak Dialect 1. Firebird can read them and write to them but to avoid corruption, the client (connection) dialect must match the database dialect. Databases created in the Firebird era, i.e., the past decade (almost) by sentient beings should be Dialect 3.
> You should check the dialect or *your* databases using gstat -h, especially if you inherited an old database or used an out-of-date tool or a mismatched client library to create your database.
> I suspect you are getting the error because Jaybird has detected a discrepancy between the SQL dialect of the Jaybird client and the SQL dialect of the database. Take the whole deal to firebird-java and find out what you need to do in your connection settings.
