Question

I have an SQL statement:

$sql = "SELECT * FROM user_events WHERE userID =" . $uid . " OR groupID = (IN ($gId) WHERE userID IS NULL) ORDER BY timestamp DESC";

This looks like this when printed:

SELECT * FROM user_events WHERE userID = 34 OR groupID =(IN (44,45) WHERE uID IS NULL) ORDER BY timestamp DESC

What I’m trying to do is select from the database any row where either the userId matches a specific variable or where the groupID matches a CSV variable where the userID is NULL.

Can anyone explain what I’m doing wrong here? I’m quite stuck!

Answer 1

$sql = "SELECT * FROM user_events 
       WHERE userID =" . $uid . " 
       OR (groupID IN ($gId) AND userID IS NULL) ORDER BY timestamp DESC";
