mysql - #1064 - 你的 SQL 语法有错误...靠近 FROM

Question

我对 MySQL 很陌生，但在遇到这个障碍之前已经取得了一些成功。任何帮助将不胜感激。

我正在尝试根据表 2 中的匹配列更新表 1。MySQL 版本是 5.5。这是 2 个表(对相似的表/列名称表示歉意，应该事先计划好列命名):

表 1 - 域

+--------+------------------------------------------+----------------+-----------+

这是命令，似乎我使用“FROM”运行的某些命令会引发相同的错误:

UPDATE dest
  SET GoogleSearches = src.Searches,
    GoogleCPC = src.CPC
FROM domains AS dest
INNER JOIN googlesearches AS src
ON dest.DomainKeyword = src.Keyword;

尝试运行命令时遇到的错误:

#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 domains AS dest INNER JOIN googlesearches AS src ON dest.DomainKeyword = ' at line 4

Answer 1

试试这个:反转你的查询...我认为它在 mysql 中比在 sql server 中反转:

UPDATE domains AS dest
INNER JOIN googlesearches AS src ON dest.DomainKeyword = src.Keyword
  SET dest.GoogleSearches = src.Searches,
   dest.GoogleCPC = src.CPC;
