从不同的数据库行中选择

The title might not be the best fit for this post, I'm sorry about that! I've got a problem when selecting result from the database. I got 3 rows in a table called "test1", "test2" and "test3" with the values true or false. How do i select all results with the value of 1? i dont want to combine them like:

WHERE test1 = 1 AND test2 = 1 AND test3 = 1.

I want to get all results with the value of 1.

    If you mean columns then i don't see any problem with doing it the way you've done it.

    SELECT * 
    FROM tablename 
    WHERE test1 = 1 AND test2 = 1 AND test3 = 1
    

    Update #1

    CREATE PROCEDURE nameofprocedure(
       IN vartest1 INT,
       IN vartest2 INT,
       IN vartest3 INT
    )
    BEGIN
       SELECT * 
       FROM tablename 
       WHERE test1 = vartest1 AND test2 = vartest1 AND test3 = vartest1
    
    END;
    

    Update #2

    Then to call the procedure use;

    CALL nameofprocedure(1, 0, 1); or
    CALL nameofprocedure(1, 1, 1); //Mix what ever you like
