注意BETWEEN认为终点值是包含在范围内的。 NOT BETWEEN可以做相反比较: a NOT BETWEEN x AND y 等效于 a < x OR a > y BETWEEN SYMMETRIC和BETWEEN相似,不过BETWEEN SYMMETRIC不要求AND左边的参数小于或等于右边的参数。如果左参数不是小于等于右参数,这两个参数会自动被交换,这样总是会应用一个非空范围。 当...

TIMESTAMP and TIMESTAMPTZ supports microsecond precision. However, there is an option for “rounding” of fractional digits for the seconds component. To do this, we can specify a number between 0 and 6 inclusive in parenthesis after TIMESTAMP and TIMESTAMPTZ, e.g.TIMESTAMP(3)for TIMESTAMP...
