Connect to Microsoft Exchange Data as a Federated Tables in MySQL

Use the CData Cloud Hub to set up federated tables for Microsoft Exchange data in MySQL .

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

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Microsoft Exchange, allowing you to easily query live Microsoft Exchange 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 Microsoft Exchange, leveraging server-side processing to quickly return Microsoft Exchange data.

Create a Virtual MySQL Database for Microsoft Exchange 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 "Microsoft Exchange" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Microsoft Exchange.

    Specify the User and Password to connect to Exchange. Additionally, specify the address of the Exchange server you are connecting to and the Platform associated with the server.

  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 Microsoft Exchange data from any MySQL client.

Create a FEDERATED Server and Tables for Microsoft Exchange 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 fedExchange
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'cloud_hub_user', PASSWORD 'cloud_hub_passwd', HOST 'myinstance.cdatacloud.net', PORT 3306, DATABASE 'exchangedb');

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 (Contacts). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_contacts (
  ...,
  givenname  TYPE(LEN),
  size  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=utf8
CONNECTION='fedExchange/Contacts';

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 Contacts to get the table schema.

Execute Queries

You can now execute queries to the Microsoft Exchange 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 Microsoft Exchange. Refer to the following example:

SELECT 
  fed_contacts.givenname, 
  local_table.custom_field 
FROM 
  local_table 
JOIN 
  fed_contacts 
ON 
  local_table.foreign_givenname = fed_contacts.givenname;
