Just to be clear that GET CURSOR is a feature of ij only, it is not SQL.
It's an interface to the JDBC cursor mechanism, so any limit on cursor
names would come from the JDBC spec.

I think it was a mistake for ij to have these special commands that
allowed testing of JDBC features from ij. Some, like this one, look like
SQL and thus users have sometimes been suprised that they were not
supported by the engine itself.

I think a better approach would have been to write tests that used JDBC
directly (.java tests), this also mimics how actual applications would
use those features.

Dan.
