Question

I have a database called Musicology containing two tables TRACKS and ALBUM :

+----------------------------------+
|              TRACKS              |
+----------+------------+----------+
| TRACK_ID | TRACK_NAME | ALBUM_ID |   /* ALBUM_ID: foreign key from  table ALBUM */
+----------+------------+----------+

+--------------------------------------+
|              ALBUM                   |
+----------+------------+--------------+
| ALBUM_ID | ALBUM_NAME | RELEASE_DATE |   /* ALBUM_ID: primary key */
+----------+------------+--------------+

Since ALBUM_ID is a primary key of ALBUM and a foreign key of TRACKS , is it possible that ALBUM_ID will show ALBUM_NAME instead?

Like for example:

+----------+------------+----------+
| TRACK_ID | TRACK_NAME | ALBUM_ID |
+----------+------------+----------+
| 0000001  | HELLO      | 000001   |
+----------+------------+----------+

Since ALBUM_ID is a primary key, it can identify other columns on its table.

Can I have ALBUM_NAME displayed instead of ALBUM_ID ?

Answer 1

If you want to select and display track details with album name, you can write query as below:

Select t.track_id,t.track_name,a.album_name from TRACKS t 
LEFT JOIN ALBUM a ON a.album_id = t.album_id;  

Hope it helps.
