MySQL错误代码:1175在MySQL Workbench中进行UPDATE期间 [英] MySQL error code: 1175 during UPDATE in MySQL Workbench

问题描述

我正在尝试更新列visited以为其提供值1.我使用MySQL工作台，并从工作台内部的SQL编辑器中编写语句.我正在编写以下命令:

I'm trying to update the column visited to give it the value 1. I use MySQL workbench, and I'm writing the statement in the SQL editor from inside the workbench. I'm writing the following command:

UPDATE tablename SET columnname=1;

它给了我以下错误:

您使用的是安全更新模式，并且您尝试在不使用表的情况下更新表 使用KEY列的WHERE要禁用安全模式，请切换选项 ....

You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column To disable safe mode, toggle the option ....

我按照说明进行操作，并且未选中Edit菜单中的safe update选项，然后未选中Preferences，然后未选中SQL Editor.同样的错误仍然出现&我无法更新此值.拜托，告诉我怎么了?

I followed the instructions, and I unchecked the safe update option from the Edit menu then Preferences then SQL Editor. The same error still appear & I'm not able to update this value. Please, tell me what is wrong?

推荐答案

我找到了答案.问题是我必须在表名之前加上架构名.即命令应为:

I found the answer. The problem was that I have to precede the table name with the schema name. i.e, the command should be:

UPDATE schemaname.tablename SET columnname=1;

谢谢.
