sql在select语句中使用两个或多个OR条件

Question

AM trying to get status where status is not=16 or not=11 so basically i would like to get records with statuses

1 to 10 jump 11, then 12 to 15

This is my sql statement

SELECT t.*
  FROM tbl_trucks t
   WHERE t.truck_status != 11
   OR t.truck_status != 16;

In the above case only the second one is executed(!16).

I have also tried

SELECT t.*
  FROM tbl_trucks t
  WHERE t.truck_status <> 11
  OR t.truck_status <> 16

what could be wrong?

Answer 1

Use NOT IN :

SELECT t.*
FROM tbl_trucks t
WHERE t.truck_status NOT IN (11, 16);

Your code would work with AND instead of OR .

Answer 2

You are using the wrong logic. If you want to NOT show status 11 and 16 it means that you want everything that isn't 11 AND isn't 16 so:

SELECT t.*
  FROM tbl_trucks t
 WHERE t.truck_status <> 11
   AND t.truck_status <> 16
