Created: 2025-02-03 by UserComp.com Editors

Here's a detailed explanation on how to connect a spreadsheet to an Oracle database and query data:

Prerequisites

Install Oracle Client software on the machine where you want to connect the spreadsheet.
Create a connection string with the necessary details like database name, username, password, and service name.

Steps to Connect Spreadsheet to Oracle Database

Open your spreadsheet software (e.g., Microsoft Excel, Google Sheets).
Go to Data > From Other Sources > From Microsoft Query.
In the Choose Data Source dialog box, click on ODBC DSN.
Select the Oracle DSN you created earlier and click Finish.
In the Query Wizard dialog box, click SQL.
Write the SQL query to fetch the required data. For example:

SELECT * FROM employees;

Click OK to run the query.
You will see the data fetched from the Oracle database in the spreadsheet.

Refreshing Data

To refresh the data, go to Data > Refresh All.

If the data doesn't refresh, it might be due to an issue with the spreadsheet. Try opening the spreadsheet on another computer, open the data, refresh it, and save it again.
