Create and manage databases

MySQL  |  PostgreSQL  |  SQL Server

This page contains information about creating, listing, and deleting SQL Serverdatabases on a Cloud SQL instance.

A newly-created instance has asqlserver database.

For more information about creating SQL Server databases and related topics,see theSQL Server documentation.

For information about setting a default value for the type ofcollationused for the databases in an instance, seeCreating instances.

Before you begin

Before completing the tasks on this page, you must have:

If you plan to use the sqlcmd client to create or manage your databases,you must have:

  • Configured access and connected to the instance with asqlcmd client.

Create a database on the Cloud SQL instance

Note: The maximum length of the database name is 128 characters.For more information on other criteria for this name, seeDatabase Identifiers.

Console

  1. In the Google Cloud console, go to theCloud SQL Instances page.

    Go to Cloud SQL Instances

  2. To open theOverview page of an instance, click the instance name.
  3. SelectDatabases from the SQL navigation menu.
  4. ClickCreate database.
  5. In theNew database dialog, specify the name of the database.
  6. ClickCreate.

gcloud

For reference information, seegcloud sql databases create.

For information about collations in SQL Server, seeCollation and Unicode Support in the SQL Server documentation.

gcloudsqldatabasescreateDATABASE_NAME\--instance=INSTANCE_NAME\[--charset=CHARSET]\[--collation=COLLATION]

Terraform

To create a database, use aTerraform resource.

resource "google_sql_database" "database" {  name     = "my-database"  instance = google_sql_database_instance.instance.name}

Apply the changes

To apply your Terraform configuration in a Google Cloud project, complete the steps in the following sections.

Prepare Cloud Shell

  1. LaunchCloud Shell.

  2. Set the default Google Cloud project where you want to apply your Terraform configurations.

    You only need to run this command once per project, and you can run it in any directory.

    export GOOGLE_CLOUD_PROJECT=PROJECT_ID

    Environment variables are overridden if you set explicit values in the Terraform configuration file.

Prepare the directory

Each Terraform configuration file must have its own directory (alsocalled aroot module).

  1. InCloud Shell, create a directory and a new file within that directory. The filename must have the.tf extension—for examplemain.tf. In this tutorial, the file is referred to asmain.tf.
    mkdirDIRECTORY && cdDIRECTORY && touch main.tf

  2. If you are following a tutorial, you can copy the sample code in each section or step.

    Copy the sample code into the newly createdmain.tf.

    Optionally, copy the code from GitHub. This is recommended when the Terraform snippet is part of an end-to-end solution.

  3. Review and modify the sample parameters to apply to your environment.
  4. Save your changes.
  5. Initialize Terraform. You only need to do this once per directory.
    terraform init

    Optionally, to use the latest Google provider version, include the-upgrade option:

    terraform init -upgrade

Apply the changes

  1. Review the configuration and verify that the resources that Terraform is going to create or update match your expectations:
    terraform plan

    Make corrections to the configuration as necessary.

  2. Apply the Terraform configuration by running the following command and enteringyes at the prompt:
    terraform apply

    Wait until Terraform displays the "Apply complete!" message.

  3. Open your Google Cloud project to view the results. In the Google Cloud console, navigate to your resources in the UI to make sure that Terraform has created or updated them.
Note: Terraform samples typically assume that the required APIs are enabled in your Google Cloud project.

Delete the changes

To delete your changes, do the following:

  1. To disable deletion protection, in your Terraform configuration file set thedeletion_protection argument tofalse.
    deletion_protection =  "false"
  2. Apply the updated Terraform configuration by running the following command and enteringyes at the prompt:
    terraform apply

  1. Remove resources previously applied with your Terraform configuration by running the following command and enteringyes at the prompt:

    terraform destroy
