Question

Table IMAGES:

• columns- imageID, Image, and categoryID*(this being the foreign key)

Table CATEGORIES:

• columns categoryID, Category

and peform query for example:

 $sql = "SELECT categoryID FROM IMAGES WHERE image = 'exampleImage'";

I would get the result as an integer of the category ID i.e 1

My question is what would be the query to display the category that the ID belongs to? Or any suggestions on how to work around with multiple queries.

Answer 1

You want to use an inner join so it returns the records that match based on the join criteria.

SELECT Images.CategoryID, Category.Category
FROM IMAGES
INNER JOIN Category ON Category.CategoryID = Images.CategoryID
WHERE image = exampleimage
