                问题描述

                我正在尝试更新列 visited 以赋予它值 1.我使用 MySQL 工作台,并且我正在从工作台内部在 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:

                您正在使用安全更新模式并且您尝试在没有使用 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 ....

                我按照说明操作,从 Edit 菜单中取消选中 safe update 选项,然后取消选中 PreferencesSQL Editor代码>.同样的错误仍然出现&我无法更新此值.请告诉我怎么了?

                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模式名.即,命令应该是:

                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;
                

                谢谢大家.
