boolean	bindLimitParametersFirst()	Does the offset/limit clause come at the start of the SELECT statement, or at the end of the query?
protected String	insert(String fetch, String sql)
protected String	limitClause()	The SQL fragment to insert, with a ? placeholder for the actual numerical limit.
protected String	limitClause(int jdbcParameterCount, ParameterMarkerStrategy parameterMarkerStrategy)
