This documentation describes the integration of MindsDB with Microsoft OneDrive, a cloud storage service that lets you back up, access, edit, share, and sync your files from any device.

​
Prerequisites

  1. Before proceeding, ensure that MindsDB is installed locally via Docker or Docker Desktop.
  2. Register an application in the Azure portal.
    • Navigate to the Azure Portal and sign in with your Microsoft account.
    • Locate the Microsoft Entra ID service and click on it.
    • Click on App registrations and then click on New registration.
    • Enter a name for your application and select the Accounts in this organizational directory only option for the Supported account types field.
    • Keep the Redirect URI field empty and click on Register.
    • Click on API permissions and then click on Add a permission.
    • Select Microsoft Graph and then click on Delegated permissions.
    • Search for the Files.Read permission and select it.
    • Click on Add permissions.
    • Request an administrator to grant consent for the above permissions. If you are the administrator, click on Grant admin consent for [your organization] and then click on Yes.
    • Copy the Application (client) ID and record it as the client_id parameter, and copy the Directory (tenant) ID and record it as the tenant_id parameter.
    • Click on Certificates & secrets and then click on New client secret.
    • Enter a description for your client secret and select an expiration period.
    • Click on Add and copy the generated client secret and record it as the client_secret parameter.
    • Click on Authentication and then click on Add a platform.
    • Select Web and enter URL where MindsDB has been deployed followed by /verify-auth in the Redirect URIs field. For example, if you are running MindsDB locally (on https://localhost:47334), enter https://localhost:47334/verify-auth in the Redirect URIs field.

​
Connection

Establish a connection to Microsoft OneDrive from MindsDB by executing the following SQL command: 
CREATE DATABASE one_drive_datasource
WITH
    engine = 'one_drive',
    parameters = {
        "client_id": "12345678-90ab-cdef-1234-567890abcdef",
        "client_secret": "abcd1234efgh5678ijkl9012mnop3456qrst7890uvwx",
        "tenant_id": "abcdef12-3456-7890-abcd-ef1234567890",
    };
Note that sample parameter values are provided here for reference, and you should replace them with your connection parameters.
Required connection parameters include the following:
  • client_id: The client ID of the registered application.
  • client_secret: The client secret of the registered application.
  • tenant_id: The tenant ID of the registered application.

​
Usage

Retrieve data from a specified file in Microsoft OneDrive by providing the integration name and the file name: 
SELECT *
FROM one_drive_datasource.`my-file.csv`;
LIMIT 10;
Wrap the object key in backticks (`) to avoid any issues parsing the SQL statements provided. This is especially important when the file name contains spaces, special characters or prefixes, such as my-folder/my-file.csv.At the moment, the supported file formats are CSV, TSV, JSON, and Parquet.
The above examples utilize one_drive_datasource as the datasource name, which is defined in the CREATE DATABASE command.
The special files table can be used to list the files available in Microsoft OneDrive: 
SELECT *
FROM one_drive_datasource.files LIMIT 10
The content of files can also be retrieved by explicitly requesting the content column. This column is empty by default to avoid unnecessary data transfer: 
SELECT path, content
FROM one_drive_datasource.files LIMIT 10
This table will return all objects regardless of the file format, however, only the supported file formats mentioned above can be queried.

Troubleshooting Guide

Database Connection Error
  • Symptoms: Failure to connect MindsDB with Microsoft OneDrive.
  • Checklist:
    1. Ensure the client_id, client_secret and tenant_id parameters are correctly provided.
    2. Ensure the registered application has the required permissions.
    3. Ensure the generated client secret is not expired.
SQL statement cannot be parsed by mindsdb_sql
  • Symptoms: SQL queries failing or not recognizing object names containing spaces, special characters or prefixes.
  • Checklist:
    1. Ensure object names with spaces, special characters or prefixes are enclosed in backticks.
    2. Examples:
      • Incorrect: SELECT * FROM integration.travel/travel_data.csv
      • Incorrect: SELECT * FROM integration.‘travel/travel_data.csv’
      • Correct: SELECT * FROM integration.`travel/travel_data.csv`
