日期。支持从 0000-01-01 到 9999-12-31 的日期范围。以原生字节序存储为有符号 32 位整数,其值表示自 Unix 纪元起的天数:0 表示 1970-01-01,负值表示 1970-01-01 之前的天数。
示例
创建一个包含 Date32 类型列的表,并向其中插入数据:
CREATE TABLE dt32
(
`timestamp` Date32,
`event_id` UInt8
)
ENGINE = TinyLog;-- Parse Date
-- - from string,
-- - from 'small' integer interpreted as number of days since 1970-01-01, and
-- - from 'big' integer interpreted as number of seconds since 1970-01-01.
INSERT INTO dt32 VALUES ('2100-01-01', 1), (47482, 2), (4102444800, 3);
SELECT * FROM dt32;┌──timestamp─┬─event_id─┐
