Creating Databases and Users in MySQL
Historically I’ve been a Microsoft SQL Server guy but I’ve been doing quite a bit of query & analysis work on MySQL lately, though I’ve never performed any serious MySQL DBA. Well, the other day I was asked by a friend how to create a user and allow read/write access to a newly created database and this had to be done in SQL (i.e. no GUI tools or PHPMyAdmin).
Since I was starting from scratch I thought I’d put together a little script to create the database, add some data, create a user, prove that the user had write access and then tidy up after myself (always good to do!).
CREATE DATABASE ash_db;
USE ash_db;
CREATE TABLE ash_tbl (id INT NOT NULL,name CHAR(50) NOT NULL);
INSERT INTO ash_tbl (id,name) VALUES(1,'Ash');
SELECT * FROM ash_tbl;
CREATE USER 'ash_user' IDENTIFIED BY 'ash_pass';
GRANT ALL PRIVILEGES ON ash_db.* TO ash_user;
-- LOGIN AS ash_user THEN EXECUTE THIS...
INSERT INTO ash_tbl (id,name) VALUES(2,'Burton');
-- THEN LOG OUT AND COME BACK HERE
SELECT * FROM ash_tbl;
DROP TABLE ash_tbl;
DROP USER ash_user;
USE information_schema;
DROP DATABASE ash_db;
CREATE USER 'ash_user' IDENTIFIED BY 'ash_pass';
GRANT ALL PRIVILEGES ON ash_db.* TO ash_user;
-- LOGIN AS ash_user THEN EXECUTE THIS...
INSERT INTO ash_tbl (id,name) VALUES(2,'Burton');
-- THEN LOG OUT AND COME BACK HERE
SELECT * FROM ash_tbl;
DROP TABLE ash_tbl;
DROP USER ash_user;
USE information_schema;
DROP DATABASE ash_db;
