i using mysql. have 2 tables:

kecamatan id | name | slug | kota_id 1    kec1   kec1     1 2    kec2   kec2     1   kota id | namek | slugk 1    kot1   kot1 2    kot2   kot2

let's search slug containing "kot1"; result be:

id | name | slug | namek | slugk 1     null   null   kot1    kot1

 id | name | slug | namek | slugk  1    kec2   kec2   null    null
