/**
 * Too many rows (more than 1) were returned from a {@link ResultQuery}.
 * <p>
 * Like any other {@link InvalidResultException}, this exception indicates to
 * clients that the result was not what they expected, but this does not have
 * any effect on the outcome of the statement producing that result. For
 * instance, if calling {@link ResultQuery#fetchOne()} on a
 * <code>SELECT … FOR UPDATE</code> query, or
 * {@link InsertResultStep#fetchOne()} on an <code>INSERT</code> statement, the
 * database change will still be executed: the rows will still be locked or
 * inserted.
 * <p>
 * <strong>Performance</strong>
 * <p>
 * Methods throwing {@link TooManyRowsException} need to retrieve at most two
 * records from the underlying JDBC {@link ResultSet}, which, depending on the
 * {@link java.sql.Statement#getFetchSize()} /
 * {@link ResultQuery#fetchSize(int)}, might incur additional database
 * roundtrips. If this causes problems, {@link ResultQuery#fetchAny()} may be
 * preferred.
