IBConnection problem with firebird exception

[efgusmao]

Hello,

I am using TBCConnection configured for use library fbclient.dll, but when same exception raise from database the message isn't not clear, for example:

Dynamic SQL Error
SQL Error code = @1
conversion error string "@1"

I would like to fix this to facilitate the understanding of exception, someone has any idea why this occurs?

This problem happening if you are using an old Firebird client (fbclient.dll or firebird.msg) with the new server (i.e., using the v2.0.x client with the v2.5.x server), or vice-versa.
Check the fbclient.dll library version and firebird.msg version. They must match the server version.
