Use the CData ODBC Driver for Oracle in Microsoft Power Query

The CData ODBC Driver for Oracle enables you to link to Oracle data in Microsoft Power Query, ensuring that you see any updates. This article details how to use the ODBC driver to import Oracle data into Microsoft Power Query.

Connect to Oracle as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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.

Import Oracle Data

Follow the steps below to import Oracle data using standard SQL:

1. From the ribbon in Excel, click Power Query -> From Other Data Sources -> From ODBC.

2. Enter the ODBC connection string. Below is a connection string using the default DSN created when you install the driver:

   Provider=MSDASQL.1;Persist Security Info=False;DSN=CData OracleOCI Source

3. Enter the SELECT statement to import data with. For example:

    SELECT CompanyName, City FROM Customers WHERE Country = US

4. Enter credentials, if required, and click Connect. The results of the query are displayed in the Query Editor Preview. You can combine queries from other data sources or refine the data with Power Query formulas. To load the query to the worksheet, click the Close and Load button.
