我正在使用Java进行工作，并且具有以下方法：

    public ResultSet getRecordsWithinBoundingBox(int spillFarLeftValue, int spillFarRightValue, int spillMostDownwardValue, int spillMostUpwardValue) {
    ResultSet resultSet = null;

    try {
        Statement statement = dbConnection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);

        String sql = "SELECT * FROM OTH WHERE (jl<=" + spillMostUpwardValue + " AND (ih>=" + spillFarLeftValue + " AND ih<="
                + spillFarRightValue+ ") OR (il<=" + spillFarRightValue + " AND il>=" + spillFarLeftValue + ")) OR (jh>="
                + spillMostDownwardValue + " AND (ih>=" + spillFarLeftValue + " AND ih<=" + spillFarRightValue + ") OR (il<="
                + spillFarRightValue + " AND il>=" + spillFarLeftValue + ")) OR (il<=" + spillFarLeftValue + " AND ih>="
                + spillFarRightValue + " AND (jl<=" + spillMostUpwardValue + " AND jl>=" + spillMostDownwardValue + ") OR (jh>="
                + spillMostDownwardValue + " AND jh>=" + spillMostUpwardValue + ")) OR (jl<=" + spillMostDownwardValue + " AND jh>="
                + spillMostUpwardValue + " AND (il>=" + spillFarLeftValue + " AND il<=" + spillFarRightValue + ") OR (ih<="
                + spillFarRightValue + " AND ih>=" + spillFarLeftValue + ")) OR (il<=" + spillFarLeftValue + " AND ih>="
                + spillFarRightValue + " AND jl<=" + spillMostDownwardValue + " AND jh>=" + spillMostUpwardValue + ")";

        resultSet = statement.executeQuery(sql);

        statement.close( );
        resultSet.close( );
    } catch (SQLException ex) {
        Logger.getLogger(DatabaseInteractor.class.getName()).log(Level.SEVERE, null, ex);
    }

    return resultSet;
}

如您所见，我当前正在使用一个巨大的字符串从数据库中提取数据，并被告知这不是最佳解决方案。但是可悲的是我没有被告知应该怎么做。但是我觉得按照现在的方式组合一条SQL语句是冒险的，而且我想知道获得相同结果的其他方法。
