Not sure, but the only way this could happen is what it states: It's
getting tuples before it's expecting to get them.

Are you running multiple threads on the same connection?

Anyhow, the query looks innocent.

Subject: [INTERFACES] JDBC for 7.0 - Tuple received before MetaData
exception


Hello, 

I'm currently going over my log files to search for suspect error
messages. I found one suspicous error message(I only have one instance
of
this exception in my log files). Does anybody know what the reason for
this
error could be ? e.g. something on the database server side, concurrency
problems etc. 

Regards, 

	Gunnar
