Hi Helen,

I'm not wrinting this statement, I believe that Jboss sent a command
to Jaybird asking if a table exists and Jaybird generated this
statement, based on the stack traces.

What I did that make some sense, at least to me, was to take off
the "?='T'" and replace the "and ? = RDB$RELATION_NAME" with "and
<tablename> = RDB$RELATION_NAME". It seems that works fine, it
returns a row if this table exists with some attributes.

Here is the stack traces:
