Connect to OFX Data as a Federated Tables in MySQL

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

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

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

Create a Virtual MySQL Database for OFX Data

You can use any MySQL client to connect to the CData Cloud Hub and create virtual databases.

  1. Connect to the CData Cloud Hub:
    mysql --host myinstance.cdatacloud.net --user admin --password
    
  2. Once authenticated, create the virtual database for OFX:
    mysql> CREATE DATABASE ofxdb
        -> DRIVER = "OFX",
        -> DBURL = "OFXUser=myUser;OFXPassword=myPassword;FIID=myFIID;";
    

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

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

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

CREATE TABLE fed_invbalances (
  ...,
  id  TYPE(LEN),
  amount  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=utf8
CONNECTION='fedOFX/InvBalances';

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 InvBalances to get the table schema.

Execute Queries

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

SELECT 
  fed_invbalances.id, 
  local_table.custom_field 
FROM 
  local_table 
JOIN 
  fed_invbalances 
ON 
  local_table.foreign_id = fed_invbalances.id;
