新! Documentation

• Developer Guides

• Examples

• LINKS HERE

新樣式 - 重點在開發人員

4


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

8


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;

9

INSERT INTO mytest.widgets (widget) VALUES ('{"series": 1}'), ('{"series": 7}'), ('{"series": 3}'), ('{"series": 4}'), ('{"series": 10}'), ('{"series": 2}'), ('{"series": 6}'), ('{"series": 5}'), ('{"series": 8}'), ('{"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. Error Handling

• 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

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
