SQL for INGRES?

[Jarmo V{is{nen]

Has anyone implemented an SQL-language interface for INGRES?
We are developing a visual interface for data-base system and
as part of it we would like to have an SQL query processor.

I remember that RTI planned to implement SQL for their
commercial INGRES but has anyone really bothered to do it
for university INGRES?

Free or cheap implementations preferred :-)  Many thanks!
