将多个数据添加到MySQL中的列的最佳方法

For exemple: I have 'Users' table and a 'Projects' table Multiple users can be members of a project. How do I insert multiple users into the "members" colomun of the Projects table?

Do I separate by comma like: "John, Alex, Hanna"?

I'm a begginner into MySQL, sorry if this is a dumb question. Thanks!

    You defiantly need another table. It should look like this

    Name: UserProjects

    Field: UserId

    Field ProjectID

    Those 2 fields should be primary keys (dual primary id). If you want to go down the route of 'soft deletes' then add a status column which you'll set to 0 if you delete it. Also look up insert on update for mysql.

    Trust me this is the way to go. Using a delimiter field or something will only give you problems later down the line.
