Re: [SQL] autogenerated json path

Hi,

im first time using json data type and i want to autogenerate it, because im creating crawler which uses postgresql.

This is static example for one site where path should be automatically generate 

SELECT 

file_name

,json_data#>>'{1,children,1,children,5,children,3,children,0,children,22,children,0,children,1,children,0,content}'

from src_data

where file_name ~ 'monitor.hr';

in case that i want to add into table another sites and their paths, i would like to write query which automaticaly changes paths.

SELECT 

file_name

,json_data#>>'{''||r.json_path ||''}'

,r.json_path

from src_data d,rules r

where file_name like r.file_name_prefix||'%';

is there any way to write this without writing functions which would slow process?
