Question

I’m wondering if it’s possible to move all data from one column in table to another table.
Here’s what i’m trying to do:

Table 1 : users – columns trying to read+move = oauth_access_key and oauth_access_secret

Table 2 : account_users – target columns: oauth_token_key, oauth_token_secret

The relation key between these tables is “user_id”.

Is this possible in one query? I know this is easily done in PHP, but i’m wondering if this can be done in plain SQL.

Thanks in advance.

Answer 1

UPDATE users, account_users 
SET account_users.oauth_token_key=users.oauth_access_key,  
    account_users.oauth_token_secret = users.oauth_access_secret
WHERE account_users.user_id=users.user_id;

You can use JOIN syntax on MySQL Update.
