将h2数据库上的列的默认值更改为当前时间戳

Question

I have a h2 database with a schema that is auto generated via JPA/hibernate. Now I want to alter a not-null timestamp type column on the database to default to the current time.

I actually use a trigger , and that works, but I'd like to know if there's a more elegant way to achieve this, something like (the following snippet doesn't work)

ALTER TABLE my_table ALTER COLUMN my_column SET DEFAULT CURRENT_TIMESTAMP;

I looked at the documentation and tried some variants of the above "pseudo statement" but with now success.

看起来很近，你尝试过：

ALTER TABLE <table name> ALTER COLUMN <column name> SET DEFAULT CURRENT_TIMESTAMP
