Google Cloud Self-Paced Labs

Overview

Cloud Spanner is a fully managed, mission-critical, relational database service that offers transactional consistency at global scale, schemas, SQL (ANSI 2011 with extensions), and automatic, synchronous replication for high availability.

Cloud Spanner offers:

  • Strong consistency, including strongly consistent secondary indexes.
  • SQL support, with ALTER statements for schema changes.
  • Managed instances with high availability through transparent, synchronous, built-in data replication.

Cloud Spanner offers regional and multi-region instance configurations.

What it's good for

Cloud Spanner is ideal for relational, structured, and semi-structured data that requires high availability, strong consistency, and transactional reads and writes.

Other storage options

Here are some common scenarios where you should probably consider an alternative to Cloud Spanner:

This hands-on lab shows you how to create a Cloud Spanner instance, database, and table; add a schema, write and modify data, and run a query.

Setup and Requirements

Before you click the Start Lab button

Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.

This hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access Google Cloud for the duration of the lab.

What you need

To complete this lab, you need:

  • Access to a standard internet browser (Chrome browser recommended).
  • Time to complete the lab.

Note: If you already have your own personal Google Cloud account or project, do not use it for this lab.

Note: If you are using a Chrome OS device, open an Incognito window to run this lab.

How to start your lab and sign in to the Google Cloud Console

  1. Click the Start Lab button. If you need to pay for the lab, a pop-up opens for you to select your payment method. On the left is a panel populated with the temporary credentials that you must use for this lab.

    Open Google Console

  2. Copy the username, and then click Open Google Console. The lab spins up resources, and then opens another tab that shows the Sign in page.

    Sign in

    Tip: Open the tabs in separate windows, side-by-side.

  3. In the Sign in page, paste the username that you copied from the left panel. Then copy and paste the password.

    Important: You must use the credentials from the left panel. Do not use your Google Cloud Training credentials. If you have your own Google Cloud account, do not use it for this lab (avoids incurring charges).

  4. Click through the subsequent pages:

    • Accept the terms and conditions.
    • Do not add recovery options or two-factor authentication (because this is a temporary account).
    • Do not sign up for free trials.

After a few moments, the Cloud Console opens in this tab.

Create an instance

When you first use Cloud Spanner, you must create an instance, which is an allocation of resources that are used by Cloud Spanner databases in that instance.

From the Console, from the Navigation menu select Spanner. Then click CREATE INSTANCE.

Fill in the following fields:

Instance Name: Test Instance.

Select Regional configuration and from the drop-down menu select region as us-central1.

Your instance creation page now looks like this:

CreateInstance1.png

Click CREATE. You will now see your instance on the Instance Details page.

Create a database

In the Instance Overview page, click CREATE DATABASE.

For the Database name, enter example-db, and click CREATE.

NameDatabase2.png

You're now on the Database Overview page for the new database you created.

Click Check my progress to verify the objective.

Create an instance and database

Create a schema

The Cloud Console provides two ways to create, alter, and delete tables and indexes in a database:

  • Use the default Database editor to specify each part of tables, columns, and indexes.
  • Enter SQL statements in Cloud Spanner Data Definition Language (DDL) syntax.

This lab uses DDL.

Now click CREATE TABLE.

In the DDL TEMPLATES field, replace the existing query with:

CREATE TABLE Singers ( SingerId INT64 NOT NULL, FirstName STRING(1024), LastName STRING(1024), SingerInfo BYTES(MAX), BirthDate DATE, ) PRIMARY KEY(SingerId);

Click SUBMIT.

Click Check my progress to verify the objective.

Create a schema for your database

Insert and modify data

The Cloud Console provides an interface for inserting, editing, and deleting data.

Insert data

Click Singers

In the left menu click Data, then click the INSERT button.

Replace the placeholder values for the following fields:

Field Value
SingerID: INT64 1
BirthDate: DATE NULL
FirstName: STRING 'Marc'
LastName: STRING 'Richards'
SingerInfo: BYTES NULL

Your query should look similar to this:

insert-into.png

NOTE: Make sure to replace SingerID with the given value in the Where condition.

Then click RUN.

Click table from the RESULTS and you'll see that the Singers table now has one row:

Click INSERT to add an additional row and replace the placeholder values with the following:

Field Value
SingerID: INT64 2
BirthDate: DATE NULL
FirstName: STRING 'Catalina'
LasteName: STRING 'Smith'
SingerInfo: BYTES NULL

Then click RUN.

Click table from the RESULTS and you'll see that the Singers table now has two rows:

7c99115abd2f6bd8.png

You can also insert empty string values when you enter data.

Click INSERT. Then enter in the following:

Field Value
SingerID: INT64 3
BirthDate: DATE NULL
FirstName: STRING 'Kena'
LastName: STRING ' '
SingerInfo: BYTES NULL

Then click RUN.

Click table from the RESULTS and you'll see that the Singers table now has three rows, and the row for SingerID 3 has a LastName that is an empty string:

Edit data

You will continue working on the Singers table. Check the box next to the row for SingerId 3, then click EDIT.

Enter in the following:

Field Value
BirthDate: DATE 1961-04-01
SingerInfo: BYTES NULL
[all other fields] [leave as-is]

Your query will look similar to this:

edit-singers.png

Then Click RUN.

Click table from the RESULTS tab.

The row for SingerId 3 in the Singers table now has a BirthDate value:

7408f46dbff8ded1.png

Delete data

Now try deleting some data from the table. Check the box next to the row for SingerId 2, then click DELETE.

You can safely ignore the warning that appears in the dialog. In the panel, click Confirm.

The Singers table now has two rows:

Run a query

You can execute a SQL statement on the query page of your database.

Navigate to your Spanner database by selecting DATABASE in the path at the top of your current table data page:

database-path.png

Click Query from the left menu.

Click CLEAR QUERY to clear the query you used for your table.

For the query enter:

SELECT * FROM Singers

Click RUN.

The Cloud Console displays the result of your query:

Congratulations! You've successfully created a Cloud Spanner database and executed a SQL statement using the query editor!
