How to Query Alchemy Data in MySQL Workbench

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

Connect to Alchemy 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.

Start by setting the Profile connection property to the location of the Alchemy Profile on disk (e.g. C:\profiles\Alchemy.apip). Next, set the ProfileSettings connection property to the connection string for Alchemy (see below).

Alchemy API Profile Settings

Alchemy uses API key authentication. The API key is supplied in the request URL path. To obtain an API key:

1. Sign in to your Alchemy account at https://dashboard.alchemy.com.
2. Open an existing app or create a new one.
3. Copy the app's API key from the API Key dialog.

After obtaining your API key, set the following connection properties:

• AuthScheme: Set this to APIKey.
• Network: Optional. The blockchain network slug for NFT API requests (for example, eth-mainnet, base-mainnet, polygon-mainnet). Defaults to eth-mainnet.

Set the following in the ProfileSettings connection property:

• APIKey: Set this to your Alchemy app API key.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Alchemy 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 Alchemy from MySQL Workbench

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

Connect to Alchemy through the SQL Gateway

1. In MySQL Workbench, click to add a new MySQL connection.
2. Name the connection (CData SQL Gateway for Alchemy).
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 Alchemy Data

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

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