Обсуждение: JDBC 8.0-310 + Crystal Reports 10 == Not Implemented

When trying to use the Business Objects Business View
Manager to create a Data Foundation through the
aforementioned JDBC driver, tables containing NUMERIC
fields fail to be addable, giving only the non-helpful
error message: "Not Implemented".  I know it's a problem
with the JDBC driver, because the ODBC driver works just
fine.  If I must, I will use the ODBC driver, but I
prefer the JDBC driver because it seems to work better
in other cases.  I don't have a stack trace because I'm
not accessing the JDBC driver programmatically.  I know
it's a problem with NUMERIC fields because tables not
having NUMERIC fields work just fine, and only those
with NUMERIC fields fail.  I also notice that the problem
is not fixed in the development version.

Someone else reported this before and we added additional error text to
the not implemented message to help track down what it needed to work.
Unfortunately they never tried it and got back to us.  Does the
development driver provide any more detail?

Unfortunately not.  It gives exactly the same message as the
production driver.  I wonder if this problem has to do with
incomplete support for DatabaseMetaData methods?  After all,
the tool I am using shows table schema information rather
than raw data (it's a modeling/designer tool).

Actually looking closer, the 8.0-310 driver should report "This method is
not yet implemented." and newer drivers should report "Method {0} is not
yet implemented."  Getting exactly "Not Implemented" from Crystal
Reports seems to indicate that this is their error message, not ours.
Unless of course they are taking our SQLState code for "Feature not
supported" and reporting that as "Not Implemented".  I don't have any
suggestions other than to try and contact Crystal Reports support.

Did anybody use Crystal Reports with PostgreSQL for business critical
stuff? Recently we have seen some Crystal Reports cores with PostgreSQL.

    Best regards,

        Hans

That is my conclusion as well.  After hacking around the driver a
bit, I seem to have eliminated all PSQLExceptions as the cause of
the failure.  So either one of the other exceptions is getting
thrown, or Crystal has a problem with a function result, rather
than an exception.  I got the driver to give me a log file of the
debug messages, if anyone thinks it would help.
