Connect to Kintone Data as a Federated Tables in MySQL

Use the SQL Gateway and the ODBC Driver to set up federated tables for Kintone data in MySQL .

You can use the SQL Gateway to configure a MySQL remoting service and set up federated tables for Kintone data. The service is a daemon process that provides a MySQL interface to the CData ODBC Driver for Kintone: After you have started the service, you can create a server and tables using the FEDERATED Storage Engine in MySQL. You can then work with Kintone data just as you would local MySQL tables.

Connect to Kintone Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

In addition to the authentication values, set the following parameters to connect to and retrieve data from Kintone:

  • Url: The URL of your account.
  • GuestSpaceId: Optional. Set this when using a guest space.

Authennticating with Kintone

Kintone supports the following authentication methods.

Using Password Authentication

You must set the following to authenticate:

  • User: The username of your account.
  • Password: The password of your account.

Using Basic Authentication

If the basic authentication security feature is set on the domain, supply the additional login credentials with BasicAuthUser and BasicAuthPassword. Basic authentication requires these credentials in addition to User and Password.

Using Client SSL

Instead of basic authentication, you can specify a client certificate to authenticate. Set SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword. Additionally, set User and Password to your login credentials.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Kintone data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.

Create a FEDERATED Server and Tables for Kintone 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 ODBC Driver for Kintone. Note that the username and password of the FEDERATED server must match a user account you defined on the Users tab of the SQL Gateway.

OPTIONS (USER 'sql_gateway_user', PASSWORD 'sql_gateway_passwd', HOST 'sql_gateway_host', PORT ####, DATABASE 'CData Kintone Sys');

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

CREATE TABLE fed_comments (
  creatorname  TYPE(LEN),
  text  TYPE(LEN),

NOTE: The table schema for the FEDERATED table must match the remote table schema exactly. You can always connect directly to the MySQL remoting service using any MySQL client and run a SHOW CREATE TABLE query to get the table schema.

Execute Queries

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

  local_table.foreign_creatorname = fed_comments.creatorname;
