Thread: ResultSetMetaData.isNullable(i) not working?

Hi all,

has someone else tried to use ResultSetMetaData.isNullable(i) to determine
if a column is nullable?

It seems that the driver always returns columnNullableUnknown - independently
if the datasource is a table or view and independ on actual settings.

I can see that it is almost impossible to determine that for columns of views
- or does someone know the trick?

But at least for tables it should work...

This has only been implemented in the cvs version of the driver and only
works on 7.4+ servers.  Try one of the snapshots available here:
