Question

I have one database with 6 tables.

One of the table is named category and it has 5 or 6 categories in it.

For example: Movie category that has the comedy, drama, thriller, horror, romance sub categories etc.

So can I, in the table, add the sub categories, or should I create them like tables?

And if I have a lot of data to add in the database is there any easier way to do it?

I’m working with xampp.

Answer 1

Add a categoryOf field to the category tabel, it will be used to store the id of the ‘parent category’.

For a sub category use this field to point to the category of which it is a sub category of.
Leave the field empty for (main) category entries

For example:

id  name         categoryOf
0   comedy       NULL
1   drama        NULL
2   sub-comedy   0
3   sub-drama    1
4   sub-comedy2  0

Note: Using this method, you can even add sub-sub-categories if you like…
