From source file:lasige.steeldb.jdbc.BFTRowSet.java

/**
 * Sets the designated column in either the current row or the insert
 * row of this <code>CachedRowSetImpl</code> object with the given
 * <code>Ref</code> value./*from  ww  w  . ja v a  2  s.c  o  m*/
 *
 * This method updates a column value in either the current row or
 * the insert row of this rowset, but it does not update the
 * database.  If the cursor is on a row in the rowset, the
 * method {@link #updateRow} must be called to update the database.
 * If the cursor is on the insert row, the method {@link #insertRow}
 * must be called, which will insert the new row into both this rowset
 * and the database. Both of these methods must be called before the
 * cursor moves to another row.
 *
 * @param columnIndex the first column is <code>1</code>, the second
 *        is <code>2</code>, and so on; must be <code>1</code> or larger
 *        and equal to or less than the number of columns in this rowset
 * @param ref the new column <code>java.sql.Ref</code> value
 * @throws SQLException if (1) the given column index is out of bounds,
 *        (2) the cursor is not on one of this rowset's rows or its
 *        insert row, or (3) this rowset is
 *        <code>ResultSet.CONCUR_READ_ONLY</code>
