MySQL错误代码：MySQL Workbench中UPDATE期间的1175错误代码

本文翻译自：MySQL error code: 1175 during UPDATE in MySQL Workbench

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. 我正在尝试更新visited的列以赋予它值1.我使用MySQL工作台，并且我在工作台内部在SQL编辑器中编写语句。 I'm writing the following command: 我正在编写以下命令：

UPDATE tablename SET columnname=1;

It gives me the following error: 它给了我以下错误：

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 .... 您正在使用安全更新模式，并且您尝试更新没有使用KEY列的WHERE的表要禁用安全模式，请切换选项....

I followed the instructions, and I unchecked the safe update option from the Edit menu then Preferences then SQL Editor . 我按照说明操作，然后从Edit菜单中取消选中safe update选项，然后取消选择Preferences然后选择SQL Editor 。 The same error still appear & I'm not able to update this value. 仍然出现相同的错误，我无法更新此值。 Please, tell me what is wrong? 拜托，告诉我有什么问题？

I found the answer. 我找到了答案。 The problem was that I have to precede the table name with the schema name. 问题是我必须在表名前加上模式名称。 ie, the command should be: 即，命令应该是：

UPDATE schemaname.tablename SET columnname=1;

Thanks all. 谢谢大家。

It looks like your MySql session has the safe-updates option set. 看起来您的MySql会话设置了safe-updates选项 。 This means that you can't update or delete records without specifying a key (ex. primary key ) in the where clause. 这意味着如果不在where子句中指定密钥（例如primary key ），则无法更新或删除记录。

Try: 尝试：

SET SQL_SAFE_UPDATES = 0;

Or you can modify your query to follow the rule (use primary key in where clause ). 或者，您可以修改查询以遵循规则（在where clause使用primary key ）。
