我有一个表(example_table_1),其时间戳列声明如下:
`ts1` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
此MySQL语句生成语法错误:
CREATE TABLE example_table_2 AS
SELECT DATETIME(ts1)
FROM example_table_1
如何让我的第二个表将TIMESTAMP数据作为DATETIME列?
答案 0 :(得分:2)
create table example_table_2 as
select cast(ts1 as datetime) as ts1
from example_table_1
