}
        SQL语句中含有分表,需要根据月份取表名,这里使用%d占位;使用SQL语句时,利用String.format方法替代%d,但是这个方法不能取代两个或以上的数值类型。

	public static String querySql()
	{
		StringBuilder sql = new StringBuilder();

	/**

	public static void main(String[] args) 
	{
		String sql = querySql();
		sql = String.format(sql, "12","12");
		System.out.println(sql);
	}

}

      将“%d”改为“%s”,然后在String.format(sql,"12","12") 传入两个参数

      运行结果为

SELECT
	s.stu_no,
	s.stu_name,
	s.stu_age,
	s.stu_sex,
	c.stu_score
FROM
	t_stu_12 s
LEFT JOIN t_score_12 c ON s.stu_id = c.stu_id
