## Create a dataset from an Azure SQL connection

To create a dataset from AzureSQL, click on the "create from icon", you will then be able to:

* Select the `Database`
* Add a Query: you can query `tables`, `views`, and even stored procedures using the AZURE SQL.

{% hint style="success" %}
After selecting data from your connector you will be able to create a dataset thanks to [YouPrep](https://docs-v3.toucantoco.com/data-management-in-datahub/datasets-in-toucan/preparing-data/overview-of-youprep-tm) using the selection as "source step".
