> It would be very helpful to have methods PreparedStatement.getMetaData() and also PreparedStatement.getParameterMetaData()
> I especially would like PreparedStatmeent.getMetaData() implemented, as I could prepare
a SQL statement, and then get information about the result set, as well as information that
the query is valid.
> I am pretty sure this information is available in some form. When you do an "EXPLAIN
query", the explain operation shows information about the result set including the column
name/aliases and the column types.
> thanks you
