在 mysql workbench 執行 SQL 發生以下錯誤：
Error Code: 1175
You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column

該怎麼辦呢？

1. 打開 mysql workbench
2. Edit → Preferences
3. workbench 6.0，選擇 SQL Queries 頁籤
   
   
4. workbench 6.3，選擇 SQL Editor 頁籤
   
   
5. 反勾選Safe Updates. Forbid UPDATEs And DELETEs with no key in WHERE clause or no LIMIT clause. Requires a reconnection
6. workbench 重新連線
7. 即可正常執行
