Hi,
While developing a web application I moved the underlying database from
firebird 1.5 to 2.1 (classic amd64 on Linux), and since that change, some of
my queries fail with the shown exception below.

After seeing the message 'GDS Exception. 335544334. conversion error from
string "DP"' I grepped my sources for a string DP, and there is none...
Do you have an idea what could go wrong here?

Best regards,
Yves
