Cloud SQL for SQL Server error messages

This page discusses some of the error messages encountered in Cloud SQL.

Overview

Error messages in Cloud SQL come from many sources and appear in many places. Some error messages come from the database engines themselves, some from the Cloud SQL service, some from client applications, and some are returned by calls to the Cloud SQL Admin API.

This page includes some of the most common errors seen in Cloud SQL. If you do not find the error code or message you are looking for here, you can look for source reference material here:

Operations error messages

Bad request

Your see the error message HTTP Error 400 Bad Request.

The issue might be

Bad Request can have many causes. Illegal Argument is one of the most common. In this case, the request is either using the wrong argument or an invalid value for the argument. For the many other causes, the error message might contain a useful hint.

Things to try

For Illegal Argument, check the request to make sure each argument is permissible and each value for the argument is valid. For all other causes, check the log files to see if there is more information available.


Access denied for user

You see the error message Access denied for user 'XXX'@'XXX' (using password: XXX).

The issue might be

There could be several causes, including:

  • The username (or password) is incorrect.
  • The user is connecting from a URL other than @XXX.
  • The user doesn't have the correct privileges for the database they are trying to connect to.

Things to try

  • Verify the username and corresponding password.
  • Check the origin of the connection to see if it matches the URL where the user has access privileges.
  • Check the user's grant privileges in the database.

Disk is full

You see the error message Disk is full, or you notice you have run out of disk space.

The issue might be

The primary instance disk size can become full during replica creation.

Things to try

Edit the primary instance to upgrade it to a larger disk size.


Fatal error during upgrade

You see the error message ERROR_INTERNAL_FATAL when upgrading resources on an instance.

The issue might be

There could be many causes.

Things to try

Logs may reveal more information. Otherwise, contact customer support to force recreate the instance.


HTTP Error 409

You see the error message HTTP Error 409 in a Terraform script, or Error 409 Operation failed because another operation was already in progress.

The issue might be

  1. Check the Terraform script. The script must wait for each operation to complete before beginning the next one.
  2. HTTP Error 409: Operation failed because another operation was already in progress.
  3. You are trying to re-use the same name for a new instance as a recently deleted one before the end of the waiting period for name re-use.

Things to try

  1. If running a Terraform script, halt execution until each instance operation is completed. Have the script poll and wait until a 200 is returned for the previous operation ID. Otherwise, wait for the currently running operation to finish.
  2. After deleting an instance, you have to wait a week before you can re-use the same name for a new instance.

Internal error

You see the error message {"ResourceType":"sqladmin.v1beta4.instance", "ResourceErrorCode":"INTERNAL_ERROR","ResourceErrorMessage":null}.

The issue might be

The service project could be missing the service networking service account required for this feature.

Things to try

To repair service permissions, disable the Service Networking API, wait five minutes and then re-enable it.


Network association failed

You see the error message Network association failed due to the following error: set Service Networking service account as servicenetworking.serviceAgent role on consumer project.

The issue might be

The Service Networking API is not enabled in the project.

Things to try

Enable the Service Networking API in your project. If you see this error when you are trying to assign a private IP address to a Cloud SQL instance, and you are using a shared VPC, you also need to enable the Service Networking API for the host project.


Not authorized to connect

You see the error message Unauthorized to connect.

The issue might be

There can be many causes, as authorization occurs at many levels.

  • At the database level, the database user must exist and its password match,
  • At the project level, the user may not have the correct IAM permissions, including the serviceusage.services.use or cloudsql.instances.connect permissions.
  • At the network level, if the Cloud SQL instance is using public IP the connection's source IP must be in an authorized network.

Things to try

  • Ensure the user exists and its password matches.
  • Assign the Service Usage Consumer role to the user account. This role includes the permission serviceusage.services.use.
  • If using public IP, ensure the source IP is in an authorized network.

Quota exceeded

You see the error message RESOURCE_EXHAUSTED: Quota exceeded, or GLOBAL_ADDRESSES_QUOTA_EXCEEDED.

The issue might be

You reached the limit of your per-minute or daily quota. Review the quotas and limits for Cloud SQL.

Things to try

Request an increase to your quotas from the Google Cloud Console.


Request is missing a valid API key

You see the error message HTTP Error 403: PERMISSION_DENIED. The request is missing a valid API key.

The issue might be

You might not have a valid service account key JSON file, or it might not be stored in the expected location.

Things to try

Verify that you have a valid service account key JSON file in the location stored in the GOOGLE_APPLICATION_CREDENTIALS environment variable and that the variable points to the correct location.


System error occurred

You see the error message [ERROR_RDBMS] system error occurred

The issue might be

  1. The user might not have all the Cloud Storage permissions it needs.
  2. The database table might not exist.

Things to try

  1. Check that you have at least WRITER permissions on the bucket and READER permissions on the export file. For more information on configuring access control in Cloud Storage, see Create and Manage Access Control Lists
  2. Ensure the table exists. If the table does exist, confirm that you have the correct permissions on the storage bucket.

Table definition has changed

You see the error message Table definition has changed, please retry transaction when dumping table.

The issue might be

During the export process a change occurred in the table.

Things to try

The dump transaction can fail if you use the following statements during the export operation:

  • ALTER TABLE
  • CREATE TABLE
  • DROP TABLE
  • RENAME TABLE
  • TRUNCATE TABLE
Remove any of these statements from the dump operation.


Temporary file size exceeds temp_file_limit

You see the error message Temporary file size exceeds temp_file_limit.

The issue might be

The temp_file_limit flag is set too low for your database usage.

Things to try

Increase the temp_file_limit size.


Unknown error

You see the error message Unknown error.

The issue might be

  1. If you see this while trying to export database to a Cloud Storage bucket. The transfer may be failing due to a bandwidth issue.
  2. If you see this during automated or manual backups, it's likely that the instance disk is full.
  3. If you see this while trying to create a new instance, it may be because you are trying to re-use the same name as a recently deleted instance.

Things to try

  1. The Cloud SQL instance may be located in a different region than the Cloud Storage bucket. Reading and writing data from one continent to another involves a lot of network usage, and can cause intermittent issues like this.
  2. If the temporary file size is taking up too much space, you can restart the instance to remove that file and free up that disk space. Otherwise, you might need to upgrade your instance to a larger disk size.
  3. Inspect the logs in Cloud Logging to find the actual error. If the error is: set Service Networking service account as servicenetworking.serviceAgent role on consumer project, disable and re-enable the Service Networking API. This action creates the service account necessary to continue with the process.
  4. Instance names cannot be re-used until a week after deletion.
