How to Query Oracle Data in MySQL Workbench

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

Connect to Oracle 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.

To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

• Port: The port used to connect to the server hosting the Oracle database.
• User: The user Id provided for authentication with the Oracle database.
• Password: The password provided for authentication with the Oracle database.
• Service Name: The service name of the Oracle database.

Configure the SQL Gateway

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

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

Connect to Oracle through the SQL Gateway

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

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

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