Pass variable from one notebook to another

[ADB0513]

I have a main notebook where I am setting a python variable to the name of the catalog I want to work in.  I then call another notebook, using %run, which runs an insert into using a SQL command where I want to specify the catalog using the catalog variable from the main notebook.  What is the best way to accomplish this?  Is there a way to pass the variable to the notebook that is being called from the %run command?  Should I use a widget?  Should I use spark.conf?

Thanks in advance for the help.

Hi @ADB0513, To pass variables between notebooks in Databricks, you can use three main methods: **Widgets**, where you create and retrieve parameters using `dbutils.widgets` in both notebooks; **spark.conf**, where you set and get configuration parameters; and **Global Variables**, which are less recommended due to scope issues. Widgets and `spark.conf` are generally more robust and maintainable, especially for CI/CD setups.

Would you like more details on any of these methods? Or do you have any other questions about your CI/CD setup with Databricks Asset Bundles?
