Question

I’m trying to copy only a single column from a table to a newly created table.

Here is my SQL:

CREATE TABLE whatever(
            id INT NOT NULL AUTO_INCREMENT,
            PRIMARY KEY(id),
            uid INT,
            can_view TINYINT DEFAULT 0
        )

This works fine, however, I need to modify it so it populates the ‘uid’ column with the ‘id’ values from my users table.

Anyone have any idea how to go about this?

I tried

uid INT (SELECT id FROM users)

Which doesn’t seem to work

Create as Select:

CREATE TABLE whatever(
        id INT NOT NULL AUTO_INCREMENT,
        PRIMARY KEY(id),
        uid INT,
        can_view TINYINT DEFAULT 0
    ) AS SELECT id AS uid FROM users;
