i have some static data which stored in a json file
outinfo=
[{out_id:123,out_name:'hello'}]
and i have a table,
----tableA----
| id | label | out_id |
| 1 | a | 123 |
| 2 | b | 123 |
i wanna select all info out like
{id:1,label:"a",out_name:"hello"}
it is easy to achieve that by import the outside json data into db table, and selelct them out though a simple left join
query
but i wanna know how to achieve that if don't create a table for those static datas.
