我们可以通过向 EXARCT() 函数提供单位值“quarter”来实现。示例如下 -
mysql> Select EXTRACT(Quarter from '2017-07-29'); +------------------------------------+ | EXTRACT(Quarter from '2017-07-29') | +------------------------------------+ | 3 | +------------------------------------+ 1 row in set (0.00 sec)
以上查询将给出特定给定日期的季度值。
mysql> Select EXTRACT(Quarter from now()); +-----------------------------+ | EXTRACT(Quarter from now()) | +-----------------------------+ | 4 | +-----------------------------+ 1 row in set (0.00 sec)
以上查询将给出当前日期的季度值。
