--- Comment #5 from Alex Thurgood <iplaw67 at tuta.io> ---
@Alexander : from the trace you have provided via the crash reporter, several
exceptions appear to be caught at lines 806 (explicit catch test for obtaining
MetaData from the db), 813 (test for whether the ESCAPE PROCESSING PROPERTY has
been set,  and 814 (explicit catch test) in SingleSelectQueryComposer.cxx

Reading the comment at line 796 of that same file, which refers to an OOo bug
for Access:

https://bz.apache.org/ooo/show_bug.cgi?id=110111

and from Ocke's comments at the time :

https://bz.apache.org/ooo/show_bug.cgi?id=110111#c8

I'm guessing that the corresponding LO MetaData.cxx code needs adjusting
somehow to present the correct sequence, however, there are quite a few of
these in the LO source code, so I'd hasard a guess and say it might be :

/core⁩/connectivity⁩/source⁩/drivers⁩/jdbc⁩/ResultSetMetaData.cxx

or

/core⁩/connectivity⁩/source⁩/drivers⁩/jdbc⁩/DatabaseMetaData.cxx

or

/core/connectivity/source/drivers/writer/WDatabaseMetaData.cxx


in this particular instance, as your connection is JDBC and you mentioned you
were trying to open a form (which is a Writer document).



You don't say what your form is based on, and whether or not it contains
subforms, as this would help pinpoint the issue further.

Additionally, the mysql ConnectorJ/8.x series is known to produce a number of
buggy behaviours currently with LO, so perhaps switching back to a 5.x series
might provide a workaround for the time being.
