MySQL:可以在存储过程的更新中使用内部联接吗？

Question

这是我试图工作但无济于事的代码:

CREATE DEFINER=`auser`@`localhost` PROCEDURE `listings_set_image`(
  IN inPropertyId INT, IN inImage VARCHAR(150), IN inCaption(255))
BEGIN
  INNER JOIN    property_images pi
    ON pi.image_id = i.image_id
  UPDATE images i SET i.image_name = inImage, i.image_caption = inCaption 
  WHERE pi.property_id = inPropertyId;
END//

我哪里做得不对？

Answer 1

您的UPDATE语法不正确；连接应构成table_references的一部分:

UPDATE images i JOIN property_images pi USING (image_id)
SET    i.image_name = inImage, i.image_caption = inCaption
WHERE  pi.property_id = inPropertyId;
