Question

I have two tables:

CREATE TABLE tblEatables (
    `EatId` int UNSIGNED PRIMARY AUTO_INCREMENT,
    `Fruits` varchar(9) NOT NULL
) Engine=InnoDB;

CREATE TABLE tblConfirm_Eatables (
    Eatables_Id INT UNSIGNED,
    Edible_Status INT,
    FOREIGN KEY Eatables_Id REFERENCES tblEatables (EatId)
) Engine=InnoDB;

I want to select all the tblEatables.Fruits which are in tblConfirm_Eatables that have an Edible_Status of 0, and those which are not in tblConfirm_Eatables.

Sample data:

INSERT INTO tblEatables
(`EatId`, `Fruits`)
    VALUES
(1, 'Apples'),
(2, 'Oranges'),
(3, 'Papaya'),
(4, 'Jackfruit'),
(5, 'Pineapple'),
(6, 'Mango');

INSERT INTO tblConfirm_Eatables
    VALUES
(1,0),
(2,1),
(3,0),
(4,0);

The results should be:

  Fruits
  Apple
  Papaya
  Jackfruit
  Pineapple
  Mango

Note “Orange” is not there since it has an edible status of “1”.

Answer 1

Try This

SELECT fruits FROM tblEatables WHERE EatID 
 NOT IN
 (SELECT Eatbles_Id WHERE  Edible_Status = 1)
