Column in where clause is ambiguous - What does that mean?

Question

I\'ve come across this error in MySQL for the join clause but I\'m fairly new to the JOIN argument and I\'m not sure what this means. Can anyone help?

Answer 1

You need to fully qualify id because venues and venues_meta both have a column called id.

Answer 2

I think you want:

SELECT * FROM `venues` v, `venues_meta` m  where v.venue_id = m.id AND  m.id = '12'

(but be sure it's v.venue_id you want and not v.id)

Answer 3

Try this Code

SELECT v.*
FROM `venues` AS `v` 
INNER JOIN `venues_meta` AS `vm` ON `vm`.`venue_id` = `v`.`id` 
WHERE `v`.`id` = '12'
