它给了我：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM poblacion p WHERE jos_ezrealty.alias LIKE '%' || p.locality || '%'' at line 5

Answer 1

请阅读UPDATE syntax for MySQL。

UPDATE jos_ezrealty AS e
  JOIN poblacion p
    ON e.alias LIKE '%' || p.locality || '%'
SET e.locid = p.id
  , e.locality = p.locality
  , e.owncoords = 1 ;

Answer 2

应该是这样的：

UPDATE jos_ezrealty join poblacion 

SET jos_ezrealty.locid = p.id

,jos_ezrealty.locality = p.locality

,jos_ezrealty.owncoords = 1

WHERE jos_ezrealty.alias LIKE CONCAT('%', p.locality, '%');
