适用于 ✅ 开源版 ✅ 专业版 ✅ 企业版
从 datetime 值中提取 MILLENNIUM 值。
MILLENNIUM 函数是 EXTRACT 的简短版本，传递一个 DatePart.MILLENNIUM 值作为参数。
SELECT millennium(DATE '2020-02-03');
create.select(millennium(Date.valueOf("2020-02-03"))).fetch();
结果是
+------------+ | millennium | +------------+ | 3 | +------------+
方言支持
此示例使用 jOOQ
millennium(Date.valueOf("2020-02-03"))
