### 把 mysql sql\_mode 設置為嚴格模式的方法
1.可以通過執行[SQL語句]:
``` 
set sql_mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION";  
  ```
2.通過修改MySQL的配置文件，在配置文件中查找sql-mode，將此行修改成為：  
  ```
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"  
  ```
如果查找不到sql-mode=則在[mysqld]下加入即可

### 嚴格模式的優點
1. sql語句更嚴格了，不能進行隱式轉換
2. 查詢速度更快
