SQL many-to-many query problem. HELP !

I have 3 tables:

1. tblSports which has an ID and Sport columns (basketball, baseball,
football, and volleyball)

2. tblTeams with an ID and Team columns (TeamsA to D)

3. tblJoin which has two foreign key columns (ID for Sports, ID for
Teams) This is where teams are joined to whatever Sports they play.

Questions:

1. How should I do my select statement when given the team
it'll show the sports they do NOT play?

2. Just the opposite of the 1st. Given the sport, what teams do NOT
play?

Thanks in advance for your help.

SELECT S.sport_id, S.sport_name
FROM tblSports AS S
WHERE NOT EXISTS
(SELECT *
FROM tblJoin
WHERE sport_id = S.sport_id
AND team_id = ???)

SELECT T.team_id, T.team_name
FROM tblTeams AS T
WHERE NOT EXISTS
(SELECT *
FROM tblJoin
WHERE team_id = T.team_id
AND sport_id = ???)

Hi, I am stuck and cannot think my way out of this small problem. I am coding in PHP but trying to write a MySql query. I have db that stores vehicles. I am trying to SELECT vehicles where the date_sold field is less than the date_sold field + 7 days. The idea is the site still displays vehicles for 7 days after they are sold.

Hi all, I've been trying to figure this out for the last day and a half and it has me stumped. I've got a web application that I wrote that keeps track of trading cards I own, and I'm moving it from an Access 2000 database to a SQL Server 2000 database. Everything worked perfectly in Access, but I'm having trouble getting data to display in SQL Server. For reference, here's the query. It's big and nasty, but I thought

I previously posted about a problem where it seemed that changing the case of the word "BY" in a SELECT query was causing it to run much much faster. Now I've hit the same thing again, where basically almost any change I make to how the query is executed (so that it still performs the same function) causes the performance to jump from a dismal 7 or 8 seconds to instantaneous. It's a very simple query of the form: SELECT Min(MyValue)...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
