Hi @arkiboys ,
Thankyou for using Microsoft Q&A platform and posting your query.
As I understand your ask, you want to perform SQL queries on Dataframe in Databricks. Please let me know if my understanding is incorrect.

All sql queries which we want to perform on dataframes can be done from functions available inside pyspark.sql library. For example, as you mentioned for performing WHERE clause of SQL we can make use of filter() function on dataframe

If you are looking for explicitly writing only SQL queries on dataframe then I will suggest to create a temp view from Dataframe and then write sql on it directly. Please check below screenshot :

Hope this will help. Please let us know if any further queries.
