Connect to Office 365 Data as a Federated Tables in MySQL

Use the CData Cloud Hub to set up federated tables for Office 365 data in MySQL .

You can use the CData Cloud Hub to set up federated tables in MySQL for Office 365 data. The Cloud Hub provides a MySQL interface for Office 365: After configuring a virtual MySQL database for Office 365, you can create a server and tables using the FEDERATED Storage Engine in MySQL. You can then work with Office 365 data just as you would local MySQL tables.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Office 365, allowing you to easily query live Office 365 data alongside existing MySQL data — all without replicating the data. Using optimized data processing out of the box, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to Office 365, leveraging server-side processing to quickly return Office 365 data.

Create a Virtual MySQL Database for Office 365 Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "Office 365" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Office 365.

    Office 365 uses the OAuth authentication standard. To authenticate requests, you will need to obtain the OAuthClientId, OAuthClientSecret, and OAuthCallbackURL by registering an app with Office 365. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Office 365 data from any MySQL client.

Create a FEDERATED Server and Tables for Office 365 Data

After you have configured and started the service, create a FEDERATED server to simplify the process of creating FEDERATED tables:

Create a FEDERATED Server

The following statement will create a FEDERATED server based on the Cloud Hub. Note that the username and password of the FEDERATED server must match a user account you defined on the Cloud Hub.

CREATE SERVER fedOffice365
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'cloud_hub_user', PASSWORD 'cloud_hub_passwd', HOST 'myinstance.cdatacloud.net', PORT 3306, DATABASE 'office365db');

Create a FEDERATED Table

To create a FEDERATED table using our newly created server, use the CONNECTION keyword and pass the name of the FEDERATED server and the remote table (Files). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_files (
  ...,
  name  TYPE(LEN),
  size  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=utf8
CONNECTION='fedOffice365/Files';

NOTE: The table schema for the FEDERATED table must match the remote table schema exactly. You can always connect directly to the Cloud Hub using any MySQL client and run SHOW COLUMNS FROM Files to get the table schema.

Execute Queries

You can now execute queries to the Office 365 FEDERATED tables from any tool that can connect to MySQL, which is particularly useful if you need to JOIN data from a local table with data from Office 365. Refer to the following example:

SELECT 
  fed_files.name, 
  local_table.custom_field 
FROM 
  local_table 
JOIN 
  fed_files 
ON 
  local_table.foreign_name = fed_files.name;
