Mysql order by percent of two values sum -

-

so need order percent counted 2 values of 1 field data stored in json.

the field name values stored named program_invested_details , example value is:

{"invested":"120.00","received":"1.08"}

i need $query (received * 100 / invested) field

select *, ($query) perrcent_total  programs_list  program_add_status = 4 , program_status = 1 order perrcent_total desc

how possible make?

by default mysql not have ability parse json string.

one option use extension such common_schema add ability parse json , extract fields (see get_option). not sure of performance hit take extension.

another option query data , parse json in client program. once again, there significant performance impact if there lot of data.
