Importing Data into Cloud SQL

MySQL | PostgreSQL

This page describes how to import data into Cloud SQL using a SQL dump file.

For best practices for importing data, see Best Practices for Importing and Exporting Data.

Importing SQL dump files to Cloud SQL

Before you begin

SQL dump files must have been created with the correct parameters.

For help with creating SQL dump files ready for import into Cloud SQL, see Exporting Data.

The database you are importing into must already exist on your Cloud SQL instance.

For help with creating a database, see Creating a database.

Importing a SQL dump file

To import a SQL dump file to a Cloud SQL instance:

Console

Create your SQL dump file, if you haven't already, using the instructions in Exporting Data to ensure that your dump file is useable by Cloud SQL.
Create a Cloud Storage bucket, if you haven't already.
For help with creating a bucket, see Creating Storage Buckets.
Upload the dump file to your bucket.
For help with uploading files to buckets, see Uploading an Object.
Go to the Cloud SQL Instances page in the Google Cloud Platform Console.
Go to the Cloud SQL Instances page
Select the instance to open its Instance details page.
Click Import in the button bar.
Enter the path to the bucket and SQL dump file you uploaded, or browse to it by clicking Browse and doubleclicking the name of the bucket and then selecting the file and clicking Select.
You can use a compressed (.gz) or an uncompressed (.sql) file.
Provide the name of the database you want to import the data into.
If you want to specify a PostgreSQL user to perform the import, open the Advanced options and select the user.

By default, imports are performed by the cloudsqlsuperuser user. If your import file contains statements that must be performed by a specific user other than cloudsqlsuperuser, use this field to specify that user.
Click Import to start the import.

gcloud

Create your SQL dump file, if you haven't already, using the instructions in Exporting Data to ensure that your dump file is useable by Cloud SQL.
Create a Cloud Storage bucket, if you haven't already.
For help with creating a bucket, see Creating Storage Buckets.
Upload the dump file to your bucket.
For help with uploading files to buckets, see Uploading an Object.

Describe the instance you are importing to:

gcloud sql instances describe [INSTANCE_NAME]

Copy the serviceAccountEmailAddress field.

Add the service account to the bucket ACL as a writer:

gsutil acl ch -u [SERVICE_ACCOUNT_ADDRESS]:W gs://[BUCKET_NAME]

Add the service account to the import file as a reader:

gsutil acl ch -u [SERVICE_ACCOUNT_ADDRESS]:R gs://[BUCKET_NAME]/[IMPORT_FILE_NAME]

Import the database:
```
gcloud sql import sql [INSTANCE_NAME] gs://[BUCKET_NAME]/[IMPORT_FILE_NAME] \
                            --database=[DATABASE_NAME]
```
For information about using the import command, see the sql import sql command reference page.

If the command returns an error like `ERROR_RDBMS`, review the permissions; this error is often due to permissions issues.

If you do not need to retain the permissions provided by the ACLs you set previously, remove them now:

gsutil acl ch -d [SERVICE_ACCOUNT_ADDRESS] gs://[BUCKET_NAME]/[IMPORT_FILE_NAME]
gsutil acl ch -d [SERVICE_ACCOUNT_ADDRESS] gs://[BUCKET_NAME]

Create a Cloud Storage bucket, if you haven't already.
For help with creating a bucket, see Creating Storage Buckets.
Upload the dump file to a Cloud Storage bucket.
For help with uploading files to buckets, see Uploading an Object.
Provide your instance with write permissions to your bucket, and read access to the file.
For help with setting ACLs, see Setting ACLs.

Import your dump file:

ACCESS_TOKEN="$(gcloud auth application-default print-access-token)"
curl --header "Authorization: Bearer ${ACCESS_TOKEN}" \
     --header 'Content-Type: application/json' \
     --data '{"importContext":
                {"fileType": "SQL",
                 "uri": "gs://[BUCKET_NAME]/[PATH_TO_DUMP_FILE]",
                 "database": "[DATABASE_NAME]" }}' \

If you do not need to retain the permissions provided by the ACLs you set previously, remove them now.
