Select rows where one row meets a condition
I have a table with 3 columns:
UserId ProductId Status
1 100 1
1 1 0
2 100 0
4 100 0
5 1 1
5 100 1
6 2 1
I want to select all rows that have ProductId = 100 at least once per user and the user has atleast one more record other than with ProductId = 100.
Expected results:
UserId ProductId Status
1 100 1
1 1 0
5 1 1
5 100 1
I solved it like this by referring to another solution:
select "ProductId", "UserId", "Status"
from "MyTable"
WHERE EXISTS (
SELECT 1 FROM "MyTable" WHERE "ProductId" = 100
)
But it returns all users where even one record is 100.
