[TOC] ## 刪除模型數據 > 用法：`db.Delete(模型變量)` ~~~ food := Food{} //先查詢一條記錄, 保存在模型變量food //等價于: SELECT * FROM `foods` WHERE (id = '2') LIMIT 1 db.Where("id = ?", 2).Take(&food) //刪除food對應的記錄，通過主鍵Id標識記錄 //等價于： DELETE from `foods` where id=2; db.Delete(&food) ~~~ ## 根據Where條件刪除數據 > 用法：`db.Where(條件表達式).Delete(空模型變量指針)` ~~~ //等價于：DELETE from `foods` where (`type` = 5); db.Where("type = ?", 5).Delete(&Food{}) ~~~
