public class MonetStatement
extends MonetWrapper
implements Statement
A Statement suitable for the MonetDB embedded database. The object used for executing a static SQL statement and returning the results it produces. By default, only one ResultSet object per Statement object can be open at the same time. Therefore, if the reading of one ResultSet object is interleaved with the reading of another, each must have been generated by different Statement objects. All execution methods in the Statement interface implicitly close a Statement's current ResultSet object if an open one exists.
