urgent: mysql expert needed to build qury to get running hours

hello,

i have a table name: maa_gen_fix

the table has data for Power Generators running hours.

every generator whois running hours reach 500 hours needs maintenance.

maintenance is done when genrator run for 500 hours.

the hours are being taken monthly or 2-3 time per month, so you will find many generators with multiple rows per month.

the table is with these fields:

gen_id = generator id

fix_date = the date when the running hours taken.

current_hours = current ruining hours

i want you to do this:

build smart (query or Procedure or function) to predict /forecast/guess the >=500 hours

for example

month 7 Jul : 8000 hours

month 8 Aug: 8300 hours

8300-8000 = 300 hours

on 2019-10-21 today, when i run query i must see all gen_id whos running hours >= 500

you have to depend on CURRENT DATE, and read generator history to guess the hours

the table schema is attached to this project.

regards
