在Power BI中使用Postgresql存储function作为数据源

Question

I am trying to use a stored function I have written in Postgresql as a data source for a Power BI chart. The function accepts four parameters all of date type. The function signature looks like this:

get_revenue_metrics(signup_start_date, signup_end_date, revenue_start_date, revenue_end_date)

This function uses these dates in multiple where clauses to create and return a table. I want to use that table to then build charts in my dashboard.

I did come across this link which talks about using a SQL function in Power BI, but it is for Azure SQL Server and not Postgresql. From the very first step as mentioned in the link before, I do not see any option to

Select the sql function when you initially select your data sources.

Is there something I am missing? Thanks for the help!

Answer 1

The "table picker" is pretty simplistic, and for some objects you'll have to start with a SQL query. See PostgreSQL - Connect using advanced options

Answer 2

I found this video that walks you through the entire process. I am very new to power BI so it was intimidating at first but this video was pretty straight forward and easy to understand.
