How to Query Linear Data in MySQL Workbench

You can use the SQL Gateway from the ODBC Driver for Linear to query Linear data through a MySQL interface. Follow the procedure below to start the MySQL remoting service of the SQL Gateway and work with live Linear data in MySQL Workbench.

Connect to Linear 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.

You can authenticate to Linear with a personal API key or with OAuth 2.0. The API key is the simplest option for connecting with your own Linear account.

Authenticating with an API Key

Set the following connection properties:

• AuthScheme: Set this to APIKey.
• APIKey: A Linear personal API key.

To create a personal API key, log in to Linear, open Settings > Security & access > Personal API keys, select New API key, and create it. Copy the key immediately, because Linear shows it only once.

Authenticating with OAuth

OAuth requires a custom OAuth application registered in Linear (Settings > API > OAuth applications), which provides the OAuthClientId and OAuthClientSecret. Two flows are supported:

• Authorization code: Set AuthScheme to OAuth, InitiateOAuth to GETANDREFRESH, and provide OAuthClientId, OAuthClientSecret, and the CallbackURL defined in your application (e.g., http://localhost:33333). The driver opens Linear in your browser so you can grant access.
• Client credentials: Set AuthScheme to OAuthClient and provide OAuthClientId and OAuthClientSecret. This authenticates the application itself, with no browser interaction, and suits machine-to-machine integrations.

By default, the driver requests the read,write scopes. The driver refreshes the access token automatically when it expires.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Linear 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.

Query Linear from MySQL Workbench

The steps below outline connecting to the virtual Linear database created in the SQL Gateway from MySQL Workbench and issuing basic queries to work with live Linear data.

Connect to Linear through the SQL Gateway

1. In MySQL Workbench, click to add a new MySQL connection.
2. Name the connection (CData SQL Gateway for Linear).
3. Set the Hostname, Port, and Username parameters to connect to the SQL Gateway.
4. Click Store in Vault to set and store the password.
5. Click Test Connection to ensure the connection is configured properly and click OK.

NOTE: When we refer to Username and Password, we mean the credentials for the user(s) created for the SQL Gateway.

Query Linear Data

1. Open the connection you just created (CData SQL Gateway for Linear).
2. Click File -> New Query Tab.
3. Write a SQL query to retrieve Linear data, like SELECT * FROM `CData Linear Sys`.Team;

With access to live Linear data from MySQL Workbench, you can easily work with Linear, just like you would a MySQL database. Get started now with a free, 30-day trial of the CData ODBC Driver for Linear and the CData SQL Gateway.
