mysql创建表如何添加两个timestamp字段
在用mysql创建timestamp字段时出错
`Incorrect table definition; there can be only one TIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT or ON UPDATE clause`
如何解决
```
CREATE TABLE `test_table` (
`id` INT( 10 ) NOT NULL,
`create_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
`update_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
) ENGINE = INNODB;
```
