Testing MySQL 8


MySQL 8 is now available for testing. The list of features is impressive and I am sure many PHP developers will be interested in having a true data dictionary, invisible indexes, and more. Right now it is in a milestone release. I am still doing a lot of work with 5.7 and found a great way to have 8 around when I needed by using Docker. Follow the Docker install guide for your platform of choice and then run
docker run --name mysql8 -e MYSQL_ROOT_PASSWORD=hidave -d mysql:8.0

Checking to See if it Really Works

 docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS               NAMES
ae1824fc01b5        mysql:8.0           ""   About a minute ago   Up About a minute   3306/tcp            mysql8
Note that our instance of MySQL 8 has the container id of ae1824fc01b5. And odds are your container id will be anything but ae1824fc01b5.

Connect to the Container

 docker exec -it ae1824fc01b5 bash
Start up the MySQL command line interface.

# mysql -u root -p       
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 5

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MySQL 8 is running. There is no data loaded. To be able to do that from the host box, we will need to talk to the MySQL Container. And to do that we need the IP Address.
ip a show eth0                                                                                                       
6: eth0@if7:  mtu 1500 qdisc noqueue state UP group default 
    link/ether 02:42:ac:11:00:02 brd ff:ff:ff:ff:ff:ff
    inet scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::42:acff:fe11:2/64 scope link 
       valid_lft forever preferred_lft forever
Exit off the container. Now you can load your data and I used the world_x test database mysql -u root -p -h < world_x.sql


connect_errno) {
    echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;

$res = $mysqli->query("SELECT Name FROM city ORDER BY Name limit 7");

echo "City names...\n";
for ($row_no = $res->num_rows - 1; $row_no >= 0; $row_no--) {
    $row = $res->fetch_assoc();
    echo " Name = " . $row['Name'] . "\n";

Now for the first data out of MySQL 8 in the container
shell>php test.php
City names...
 Name = Abakan
 Name = Abaetetuba
 Name = Abadan
 Name = Aba
 Name = Aalborg
 Name = Aachen
 Name = A Coru�a (La Coru�a)
So the test environment is set up. Onto the tests of MySQL 8.
