Connect to an Oracle database
In order to connect to an Oracle database with Power BI Desktop, the correct Oracle client software must be installed on the computer running Power BI Desktop. Which Oracle client software you use depends on which version of Power BI Desktop you have installed - the 32-bit version or the 64-bit version.
Supported versions: Oracle 9 and later, Oracle client software 8.1.7 and later.
Determining which version of Power BI Desktop is installed
To determine which version of Power BI Desktop is installed, select File > Help > About then check the Version: line. In the following image, a 64-bit version of Power BI Desktop is installed:
Installing the Oracle client
For 32-bit versions of Power BI Desktop, use the following link to download and install the 32-bit Oracle client:
- 32-bit Oracle Data Access Components (ODAC) with Oracle Developer Tools for Visual Studio (188.8.131.52.4)
For 64-bit versions of Power BI Desktop, use the following link to download and install the 64-bit Oracle client:
Connect to an Oracle database
Once the matching Oracle client driver is installed, you can connect to an Oracle database. To make the connection, take the following steps:
From the Get Data window, select Database > Oracle Database
In the Oracle Database dialog that appears, provide the name of the server, and select Connect. If a SID is required, you can specify that using the format: ServerName/SID, where SID is the unique name of the database. If the ServerName/SID format doesn't work, try using ServerName/ServiceName, where ServiceName is the alias used when connecting.
If you're having trouble connecting in this step, try using the following format in the Server Name field: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=host_name)(PORT=port_num))(CONNECT_DATA=(SERVICE_NAME=service_name)))
If you want to import data using a native database query, you can put your query in the SQL Statement box, available by expanding the Advanced options section of the Oracle Database dialog.
Once your Oracle database information is entered into the Oracle Database dialog (including any optional information such as a SID or a native database query), select OK to connect.
If the Oracle database requires database user credentials, input those credentials in the dialog when prompted.
If you downloaded Power BI Desktop from the Microsoft Store, you might be unable to connect to Oracle databases because of an Oracle driver issue. If you encounter this issue, the error message returned is "Object reference not set". To address the issue, do one of the following:
Download Power BI Desktop from https://powerbi.microsoft.com/desktop instead.
If you want to use the version from the Microsoft Store: on your local computer, copy oraons.dll from 12.X.X\client_X into 12.X.X\client_X\bin. The X represents version and directory numbers.
