这个mysql创建触发器语句有什么问题

Question

CREATE TRIGGER google_inventory BEFORE UPDATE ON `cataloginventory_stock_item`
FOR EACH ROW 
BEGIN 
   update `catalog_product_entity_int` 
   set value=20 
   where attribute_id=552 
          and entity_id=NEW.product_id 
          and NEW.is_in_stock=0;
   update `catalog_product_entity_int` 
   set value=21 
   where attribute_id=552 
          and entity_id=NEW.product_id 
          and NEW.is_in_stock=1;
  END;

它给了我以下错误:

1064 - 您的SQL语法出错; 检查与MySQL服务器版本对应的手册,以便在第4行的''附近使用正确的语法

我是一个SQL Server的人,不能指出问题是什么.

您需要更改分隔符.没有它,分号就会结束CREATE TRIGGER语句.

CREATE TRIGGER google_inventory BEFORE UPDATE ON `cataloginventory_stock_item`
FOR EACH ROW 
BEGIN 
   update `catalog_product_entity_int` 
   set value=20 
   where attribute_id=552 
          and entity_id=NEW.product_id and NEW.is_in_stock=0;
   update `catalog_product_entity_int` 
   set value=21 
   where attribute_id=552 
          and entity_id=NEW.product_id and NEW.is_in_stock=1;
  END;
