The Workshop
• Install Virtualbox (Latest Version)
• VM
– 201608COSCUPDocStore.ova
– IMPORT to the VirtualBox
5

Disable
• USB
6

Network
• DHCP (HOST-ONLY) e.g. 192.168.56.102
– Check your IP if needed
– # ip addr
• Adapter 2 (Bridge)
– Disable (Not used in Lab)
7

Using putty / ssh client
• Using putty or ssh client to login to the OS
• User name : root
• Password : password
• Folder : /opt/mysql/solution (The main Lab Folder)
• For ALL operations, use mysql user. (Do not use root user)
– # su - mysql

Lab 01 : JSON
• Folder : /opt/mysql/solution/12-JSON
CREATE DATABASE if not exists mytest;
CREATE TABLE if not exists mytest.widgets (
id int(10) NOT NULL AUTO_INCREMENT,
widget JSON NOT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB;

INSERT INTO mytest.widgets (widget) VALUES
('{"series": 1}'),('{"series": 7}'),('{"series": 3}'),
('{"series": 11}');
select count(*) from mytest.widgets;

JSON - SELECT
• select JSON_TYPE('["a","b", 1]');
• select JSON_TYPE('"hello"');
• select JSON_EXTRACT('{"series": 4}','$.series');
• select JSON_EXTRACT('[10,20, [30, 40]]','$[1]');
• select JSON_EXTRACT('[10,20, [30, 40]]','$[2]');
• SELECT JSON_EXTRACT('[10,20, [30, 40]]', '$[1]', '$[0]');
• SELECT JSON_EXTRACT('[10,20, [30, 40]]', '$[2][*]');
• select JSON_ARRAY('a', 1, NOW());
• select JSON_OBJECT('key1',1, 'key2', 'abc', 'key3', '["a","b", 1]');
• SELECT JSON_MERGE('["a",1]', '{"key": "value"}');
10

JSON - SELECT
• select JSON_EXTRACT(widget, "$.series") from mytest.widgets;
• select widget->"$.series" from mytest.widgets ;
• select widget->>"$.series" from mytest.widgets ;
• select JSON_EXTRACT('{"name":"My Object",
"numbers":[2,4,6,8,10,12,14,16,18,20]}',"$.numbers[1]");
• select JSON_TYPE( '[{"price":10,"name":"hello"},
{"price":12,"name":"hello2"},{"price":16,"name":"hello3"},
{"price":18,"name":"hello4"}]' );
11

GENERATED COLUMN
• alter table mytest.features add
feature_type varchar(30)
as
(feature->"$.type") { VIRTUAL | STORED};
12

IMPORT (LOAD DATA) JSON to table
• Check properties.json
• load data infile '/opt/mysql/solution/12-JSON/properties.json' into table
mytest.features (feature);

Lab02- MySQL Document Store (工作坊)
• VM已準備
– MySQL 5.7.14
– MySQL Shell 1.0.4
– Nodejs and Connector
• 1. 安裝MySQLX插件
• 2. Starting MySQL Shell (mysqlsh) login session
• 3. Loading Sample Database “world_x”
• 4. Schema, Collection, Tables, Query using MySQL Shell
• 5. Creating New Collection and Inserting Data ( in Transaction mode)
• 6. ErrorHandling
• 7. Adding Generated Column to Collection
18

1. X-Plugin安裝
• install plugin mysqlx soname 'mysqlx.so';
• Create a “LOCKED” user “mysqlxyss@localhost”
– CREATE USER IF NOT EXISTS mysqlxsys@localhost IDENTIFIED WITH
– mysql_native_password AS 'password' ACCOUNT LOCK;
– GRANT SELECT ON mysql.user TO mysqlxsys@localhost;
– GRANT SUPER ON *.* TO mysqlxsys@localhost;
00-installx.sh
19

2. Starting MySQL Shell (mysqlsh) login session
• Command (mysqlsh)
• mysqlsh --uroot --h127.0.0.1 --P33060
– mysql-js> help
• Quit mysqlsh
– mysql-js> quit
• Showing the session
– mysql-js>session
01-login.sh
20

2. XSession & NodeSession
• mysql-js> var mysqlx = require(‘mysqlx’).mysqlx;
• mysql-js> var xsession = mysqlx.getSession(‘root:pwd@localhost:33060’);
• mysql-js> var nsession = mysqlx.getNodeSession(‘root:pwd@localhost:33060’);
• nsession.sql(‘use test’);
• nsession.sql(‘select 1’);
21

3. Loading ‘world_x’ sample database
• Download from URL : http://dev.mysql.com/doc/index-other.html
‘world_x’
• 03-createWorldX.sh
– mysql -uroot -h127.0.0.1 < /opt/mysql/packages/world_x-db/world_x.sql
http://dev.mysql.com/doc/index-other.html
22

4. Schema, Collection, Tables using MySQL Shell
• var myworld_x = session.getSchema('world_x');
• var mytables = myworld_x.getTables();
• var mycollections = myworld_x.getCollections();
• print("Schema : " , myworld_x);
• print("Tables :" , mytables);
• print("Collections :" , mycollections);
04a-printSTC.sh (Print Schema, Tables, Collection)
23

4. Query Collection / Table
• print("Table : City [SELECT]");
• myworld_x.City.select().limit(5).execute();
• print("Collection : CountryInfo [FIND]");
• myworld_x.CountryInfo.find().limit(1);
• print("Collection : CountryInfo [FIND - condition GNP > 1000 and Name like 'A%']");
• myworld_x.CountryInfo.find("GNP > 1000 and Name like 'A%'").limit(1);
04c-query.sh
24

5. Creating Collection and Transaction Data
• var myworld_x = session.getSchema('world_x');
• try {
• var myt = myworld_x.getCollection('mytest01') ;
• session.dropCollection('world_x', 'mytest01');
• } catch (err) {
• print("[INFO] Collection not found : mytest01");
• }
• try {
– var myColl = myworld_x.createCollection('mytest01');
– ….
11-createCollection.sh
25

5. Creating Collection and Transaction Data
• session.startTransaction();
• try {
• myColl.add({name: 'Jack', age: 15, height: 1.76, weight: 69.4}).execute();
• myColl.add({name: 'Susanne', age: 24, height: 1.65}).execute();
• myColl.add({name: 'Mike', age: 39, height: 1.9, weight: 74.3}).execute();
• // Commit the transaction if everything went well
• session.commit();
• print('Data inserted successfully.');
• } catch (err) {
session.rollback();
• }
Transaction Data

6. Error Handling
• Try, Catch, Finally
• ./13-errorHandling.sh
13-errorHandling.sh
27

6. Error Handling
• Try, Catch, Finally (passing root as user)
• ./13-errorHandling.sh root
13-errorHandling.sh
28

6. Error Handling
• Try, Catch, Finally (passing root as user and world_x as database)
• ./13-errorHandling.sh root world_x
