From a computer science student here in Sydney Australia. Thank you for making this video. It was extremely helpful. Combined with the lectures from uni I now understand what a primary/foreign key is.

Great video! Really well explained. The only part where I got a little bit lost was you explained about the symbols use to express the relation between the tables and the specified directions by the end of the video.

[@tassiblezilundu7602]

I got the point but the thing is how do those foreign key get to access values from it's primary key table in the prepared statement

[@daughterofzion3884]

The FK gets access because they have a "common" key, which opens the way to get multiple info when INPUTING column names(from both sides) in select statements. It will show up the results , because you used the PK, in addition to both tables in your select stat.

[@testa3014]

is it possible to change the pk name of one table when writing it in the next table

[@daughterofzion3884]

No, because if you do that the primary key ID will not match, which will mean you'll get an error in your syntax.

[@danablum7653]

How do we see the answers? :)
