Question

I apologize if this is a duplicate, however, I cannot find the answer I need.

Consider my data:

Table – report_detail

report_id   |category    |sub_category   |report name
-------------------------------------------------------
1           |1           |1              |Donkey Report
2           |2           |2              |Grandma Report
3           |1           |1              |Poop Report

Table – report_subscriptions

user_id     |report_id
--------------------------
1           |1            
2           |2            
1           |2

My question is, how do I select all of the report_id’s from the report_detail table that are not subscribed to user_id = 1 in report_subscriptions?

Thank you!

Answer 1

This should get you fairly close

select * from Report_detail RD
where RD.report_id not in (select disctinct RS.report_id from report_subscriptions RS)
