SQL get all Data from one table connected with another - sql

Question

I got an little DB with two tables Weeks and Users.
Every User is able to have a Week, so let's say he can have a Week but must not.
Every Week has a WeekNr. I want to do a table like that for an specific WeekNr, where all users are shown even those without a Week with that WeekNr:
-------------------------------------------+
| Users | KM Driven | Goal | CarID |
+----------+------------+------------------+
| Driver1 | 555 | Spain | 1 |
+----------+------------+------------------+
| Driver2 | 0 | 0 | 0 |
+----------+------------+------------------+
| Driver3 | 777 | Germany | 9 |
+----------+------------+------------------+
| Driver4 | 888 | UK | 86 |
+----------+------------+------------------+
If there is a user which have no Week for a WeekNr and I want all columns expected his name filled with 0. See Driver2 in table above for an example.
My query looks actually like that:
SELECT *
FROM User
INNER JOIN Week ON Week.UserId = User.UserID
WHERE WeekNr = 22;
I totally understand why I'm only getting only the drivers with weeks for the specific WeekNr, but I have no clue how to solve the issue with filling the empty one with 0 and all of this in one query.
I hope my question got clear.
Thanks for your help in advance!
EDIT:
My table look like this
Users:
---------------------------------+
| User | PW | UserID |
+----------+------------+--------+
| Driver1 | *** | 1 |
| Driver2 | *** | 2 |
| Driver3 | *** | 3 |
| Driver4 | *** | 4 |
+----------+------------+--------+
Weeks:
------------------------------------------------------+
| WeekNr | KM Driven | Goal | WeekID | UserID |
+----------+------------+-----------------------------+
| 22 | 555 | Spain | 1 | 1 |
| 22 | 0 | USA | 2 | 3 |
| 22 | 777 | Germany | 3 | 4 |
| 23 | 888 | UK | 44 | 2 |
+----------+------------+-----------------------------+

Answer 1

I hope to have correctly understood your question: your problem is in the INNER JOIN, you get only rows present in both the tables. Try with LEFT OUTER:
EDIT:
That should do the trick, given tha additional info :)
;WITH Drivers AS (SELECT u.[User], w.*
FROM Users u LEFT OUTER JOIN Weeks w On w.UserId = u.UserID
WHERE WeekNr = 22)
SELECT u.[User], ISNULL(d.[KM Driven], 0) [KM Driven] , ISNULL(d.Goal, 0) Goal --, *
FROM Users u LEFT OUTER JOIN Drivers d ON u.UserID = d.UserID

Answer 2

Is there a typo in your question? I presume CarID is meant to be a column of Weeks. If so,
SELECT
u.[User]
, ISNULL(w.[KM Driven], 0) [KM Driven]
, ISNULL(w.[Goal], '0') [Goal]
, ISNULL(w.[CarID], 0) [CarID]
FROM dbo.[Users] u
LEFT JOIN Weeks w ON u.UserID = w.UserID AND WeekNr = 22
