Examples of javax.sql.rowset.CachedRowSet.populate()

javax.sql.rowset.CachedRowSet.populate()
Populates this CachedRowSet object with data from the given ResultSet object.
This method can be used as an alternative to the execute method when an application has a connection to an open ResultSet object. Using the method populate can be more efficient than using the version of the execute method that takes no parameters because it does not open a new connection and re-execute this CachedRowSet object's command. Using the populate method is more a matter of convenience when compared to using the version of execute that takes a ResultSet object. @param data the ResultSet object containing the datato be read into this CachedRowSet object @throws SQLException if a null ResultSet object is suppliedor this CachedRowSet object cannot retrieve the associated ResultSetMetaData object @see #execute @see java.sql.ResultSet @see java.sql.ResultSetMetaData


    this.rs = noBlobsConn.createStatement().executeQuery(
        "SELECT PASSWORD ('SOMETHING')");


    crs = (CachedRowSet)Class.forName("com.sun.rowset.CachedRowSetImpl").newInstance();
    crs.populate(this.rs);
    crs.first();


    assertEquals(fromPlainResultSet, crs.getString(1));
