Hi Everyone,

we are trying to setup a Firebird server with a database that
contains a number of BLOBs. We would like to take advantage of BLOB
UDFs to work with them (e.g. convert EMF BLOBS into BMP BLOBs on
demand), but any UDF we tried that returns a BLOB failed to work
properly.
We tried our own UDFs and also some of the free udf libs out there.
Each time we call an UDF returning a BLOB, the error message is -804
and something with wrong SQLDA...

Any ideas? If this is not the right place to ask this kind of
questions, where could I get help?

Thank you
Mirco
