This page contains information about creating, listing, and deleting MySQL databases on a Cloud SQL instance.
A newly-created instance has four system databases:
information_schema
: Provides access to database metadata, information about the MySQL server.mysql
: The system schema. It contains tables that store information required by the MySQL server as it runs.performance_schema
: A feature for monitoring MySQL Server execution at a low level.sys
: Contains a set of objects that helps DBAs and developers interpret data collected by the performance schema.
Before you begin
Before completing the tasks on this page, you must have:
- Created a Cloud SQL instance. For more information, see Creating instances.
If you plan to use the mysql client to create or manage your databases, you must have:
- Configured access and connected to the instance with a
mysql
client. For more information about connection options, see Connection Options for External Applications.
Create a database on the Cloud SQL instance
Follow the rules in Schema Object Names when you create your database name. If not set on creation, new databases have the following default values:- Character set:
utf8
- Collation:
utf8_general_ci
Console
-
In the Google Cloud console, go to the Cloud SQL Instances page.
- To open the Overview page of an instance, click the instance name.
- Select Databases from the SQL navigation menu.
- Click Create database.
- In the Create a database dialog, specify the
name of the database, and optionally the character set and collation.
For more information about character sets and collations, see Character Sets, Collations, Unicode.
- Click Create.
gcloud
For reference information, see gcloud sql databases create.For more information about character sets and collations, see Character Sets, Collations, Unicode.
gcloud sql databases create DATABASE_NAME \ --instance=INSTANCE_NAME \ [--charset=CHARSET] \ [--collation=COLLATION]
Terraform
To create a database, use a Terraform resource.
