public void execute() throws SQLException {

    }
Populates this <code>CachedRowSetImpl</code> object with data.
This form of the method uses the rowset's user, password, and url or
data source name properties to create a database
connection.  If properties that are needed
have not been set, this method will throw an exception.
<P>
Another form of this method uses an existing JDBC <code>Connection</code>
object instead of creating a new one; therefore, it ignores the
properties used for establishing a new connection.
<P>
The query specified by the command property is executed to create a
<code>ResultSet</code> object from which to retrieve data.
The current contents of the rowset are discarded, and the
rowset's metadata is also (re)set.  If there are outstanding updates,
they are also ignored.
<P>
The method <code>execute</code> closes any database connections that it
creates.

@throws SQLException if an error occurs or the
                        necessary properties have not been set
