SQL query with filters

Question

I'm trying to run a SQL query but I'm not sure how to accomplish. So I have the following query that outputs the below results:

SELECT
    events.Name, results.Description, Events.Id, 
    results.EventId, results.UserId
FROM
    Events
LEFT JOIN 
    Results ON events.Id = Results.EventId

What I'm trying to do is filter out UserId = 66 and the associated eventId . So the results table should exclude rows with UserId = 66 and rows with EventId = 4 .

Answer 1

So the results table should exclude rows with UserId 66 and rows with EventId 4.

Well, you may want:

SELECT e.Name, r.Description, e.Id, r.EventId, r.UserId
FROM Events e JOIN
     Results r
     ON e.Id = r.EventId
WHERE r.UserId <> 66 AND e.eventId <> 4;

This would appear the answer the question that I've quoted. However, your query is using a LEFT JOIN and other parts of your question are somewhat ambiguous.

For instance, if you want these removed fro your specific query:

SELECT e.Name, r.Description, e.Id, r.EventId, r.UserId
FROM Events e LEFT JOIN
     Results r
     ON e.Id = r.EventId AND e.eventId <> 4
WHERE r.UserId <> 66 ;
