MySQL DELIMITER语法错误 [英] MySQL DELIMITER syntax errors

问题描述

此MySQL脚本安装多个触发器.

This MySQL script installs multiple triggers.

它可以在一台运行MySQL 5.0.51b-community的机器上运行.在另一台运行MySQL 14.12 Distrib 5.0.45的计算机上，对于redhat-linux-gnu(i386)，它会失败，并显示此错误消息，该错误消息似乎与DELIMITER // ... // DELIMITER有关；语法:

It works on one machine running MySQL 5.0.51b-community. On another machine running MySQL 14.12 Distrib 5.0.45, for redhat-linux-gnu (i386) it fails, with this error message, which seems to be related to the DELIMITER // ... // DELIMITER; syntax :

第272行的错误1064(42000):您的SQL语法有错误；检查与您的MySQL服务器版本相对应的手册，以在'DELIMITER附近使用正确的语法；如果存在触发器则触发触发器; DELIMITER"(第1行)

脚本语法(摘要)为:

DROP TRIGGER IF EXISTS trigger_name;
DELIMITER //
CREATE TRIGGER trigger_name BEFORE UPDATE ON table
FOR EACH ROW BEGIN
  -- Trigger logic goes here
END //
DELIMITER;

-- More trigger drop/create statements follow

脚本有什么问题，我该如何纠正?

What is wrong with the script, and how can I correct it?

推荐答案

尝试

DELIMITER ;

不是

DELIMITER;

您实际上是将;指定为DELIMITER命令的参数，因此，如果没有空格，可能会造成混淆.

You're actually specifying ; as an argument to the DELIMITER command, so not having the space there may be confusing it.
