Create and manage databases

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

A newly-created instance has a sqlserver database.

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

For information about setting a default value for the type of collation used for the databases in an instance, see Creating 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 a sqlcmd client.

Create a database on the Cloud SQL instance

Console

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

    Go to Cloud SQL Instances

  2. To open the Overview page of an instance, click the instance name.
  3. Select Databases from the SQL navigation menu.
  4. Click Create database.
  5. In the New database dialog, specify the name of the database.
  6. Click Create.

gcloud

For reference information, see gcloud sql databases create.

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

gcloud sql databases create DATABASE_NAME \
--instance=INSTANCE_NAME \
[--charset=CHARSET] \
[--collation=COLLATION]

Terraform

To create a database, use a Terraform 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. Launch Cloud 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 (also called a root module).

  1. In Cloud Shell, create a directory and a new file within that directory. The filename must have the .tf extension—for example main.tf. In this tutorial, the file is referred to as main.tf. 
    mkdir DIRECTORY && cd DIRECTORY && 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 created main.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 entering yes 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.

Delete the changes

To delete your changes, do the following:

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

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

    terraform destroy
