How to create Dynamics NAV federated tables in MySQL

You can use the SQL Gateway to configure a MySQL remoting service and set up federated tables for Dynamics NAV data. The service is a daemon process that provides a MySQL interface to the CData ODBC Driver for Dynamics NAV: 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 Dynamics NAV data just as you would local MySQL tables.

Connect to Dynamics NAV 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.

Before you can connect, OData Services will need to be enabled on the server. Once OData Services are enabled, you will be able to query any Services that are published on the server.

The User and Password properties, under the Authentication section, must be set to valid Dynamics NAV user credentials. In addition, you will need to specify a URL to a valid Dynamics NAV server organization root and a ServerInstance. If there is not a Service Default Company for the server, you will need to set the Company as well.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Dynamics NAV 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 Dynamics NAV 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 Dynamics NAV. 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.

CREATE SERVER fedDynamicsNAV
FOREIGN DATA WRAPPER mysql
OPTIONS (USER 'sql_gateway_user', PASSWORD 'sql_gateway_passwd', HOST 'sql_gateway_host', PORT ####, DATABASE 'CData DynamicsNAV 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 (Customer). Refer to the following template for the statement to create a FEDERATED table:

CREATE TABLE fed_customer (
  ...,
  name  TYPE(LEN),
  prices_including_vat  TYPE(LEN),
  ...,
)
ENGINE=FEDERATED
DEFAULT CHARSET=latin1
CONNECTION='fedDynamicsNAV/customer';

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 Dynamics NAV 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 Dynamics NAV. Refer to the following example:

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