edit: run mariadb if helps

select concat('[\n\t', group_concat(         column_json(             column_add(                 column_create('id', id)                 , 'name', name                 , 'price', price             )         )         order id         separator ',\n\t'     ), '\n]') json     product \g 

ignore except column_create. json creation happening. ok, have:

column_json(         column_add(             column_create('id', id)             , 'name', name             , 'price', price         )     ) 

column_add function adds columns json. each argument key paired value. 'name' key in json object , name value be. in case it's column name table product.

so, let's want query users table , first names, last names, , id. query like:

select concat('[\n\t', group_concat(         column_json(             column_add(                 column_create('id', id)                 , 'first_name', first_name                 , 'last_name', last_name             )         )         order id         separator ',\n\t'     ), '\n]') json     users \g 

and @ end of column_json command have as json, casts json type want.
