database stucture

village table:

  • id
  • village_name
  • district_id
  • lattitude
  • longitude

user table:

  • user_id
  • first_name
  • last_name
  • governorate
  • district
  • village
  • birth_date
  • email_address
  • specialization
  • user_name
  • password
  • interest
  • registered_date
  • last_log_date

i think problem in query of inner join.

your select query limiting. have selected 2 fields in 2 tables , 2 fields trying join on have been left out of selection. try using select * both tables , rectify typos , go
