mass update

I have two tables (zipcodes and zones) where I'm attempting to move zones.zone to zipcodes.zone based on a city/state match.

I've tried this but it doesn't seem to work.

UPDATE `zipcodes` set `zipcodes.zone` = `zones.zone` where `zipcodes.city` = `zones.city` and `zipcodes.state` = `zones.state`

Can someone please tell me what I'm doing wrong.

Looks like you need to join your tables:

Code:

   UPDATE 
  `zipcodes`,
  `zones`
 SET
  `zipcodes.zone` = `zones.zone`
 WHERE
  `zipcodes.city` = `zones.city` 
 AND  
  `zipcodes.state` = `zones.state`
