Question

I was wondering if I can switch the “connected” user within an sql script that is executed by mysql.

Here’s a description of my goal. Perhaps, it’s not necessary to swich the user and another solution gives me what I want.

I want to write a database creation script like so:

create databse some_db;

create user u@localhost identified by 'pw';

grant all on u.* to u;

-- Here's where I want to switch the user, but *obviously* the 
-- following command fails

connect u@localhost/pw;

-- Now, as new user, create the tables:

use some_db;

create table t (...

This script would then be called from the command line like

$ mysql -u root -p"....." < create_db.sql

Is this possible or do I have to leave the script in order to switch the connected user?

Answer 1

AFAIK, you can not change the user in the middle of the script unless you create a brand new connection with the credentials of the other user.

BTW, connect command only reconnects but there are only two optional parameters as documentation states: db and host.
