How to Resolve UsageError: Line Magic Function %sql Not Found in Jupyter Notebook

If you're an avid user of Jupyter Notebooks for data analysis and manipulation, you might have come across the error: UsageError: Line magic function %sql not found. This error typically occurs when attempting to use the %sql magic command but your Jupyter Notebook environment does not recognize it. Below, we'll explore why this happens and how to resolve it efficiently.

Understanding the Error

The %sql magic command is a special function used within Jupyter Notebooks to run SQL queries. This functionality is not part of the default Jupyter installation and usually comes from a third-party extension called ipython-sql. When Jupyter fails to recognize the %sql command, it means that the required extension is not installed or not properly configured.

Steps to Resolve the Error
