更改 MySQL 表以在列上添加注释

2021-11-20 00:00:00 mysql alter-table

我一直在检查 MySQL ALTER TABLE 文档 并且它似乎不包括向列添加或修改注释的方法.我该怎么做?

I have been checking the MySQL Documentation for ALTER TABLE and it does not seem to include a way to add or modify a comment to a column. How can I do this?

-- for table
ALTER TABLE myTable COMMENT 'Hello World'

-- for columns
-- ???

推荐答案

尝试:

 ALTER TABLE `user` CHANGE `id` `id` INT( 11 ) COMMENT 'id of user'
