The query is pasted below. Basically I have a users table, and I want to create 1 record for every entry in the users table in the controls table. I need the user_id from the users table when I'm inserting into the controls table. I get a syntax error when I try and run the query below. I've looked at a bunch of other MySQL examples that do something similar but get the same error. I'm running MySQL 5.6.21.
This will end up being a Rails migration, so I am also amenable to using ActiveRecord, but haven't really figure out how to do something like this with it.
INSERT into controls (default, whitelist, user_id, admin_status, system_status, created_at, updated_at) values (0, 0, (SELECT id FROM users), 'inactive', 'sleeping', DATE(NOW), DATE(NOW));
I believe your problem is that you're trying to mix a SELECT with VALUES (which is used for inputting literal values).
Try:
INSERT into controls
(`default`, whitelist, user_id, admin_status, system_status, created_at, updated_at)
SELECT 0, 0, id, 'inactive', 'sleeping', NOW(), NOW() FROM users;
