###開發規范

開發規范：關鍵字大寫，庫名字小寫，要有字符集
CREATE DATABSE　oldboy CHARSET utf8;? ? ###建議采用第一種
CREATE DATABSE　oldboy CHARSET utf8mb4;

?

###lower_case_table_names? ?begin###

mysql> show variables like '%lower%';
+------------------------+-------+
| Variable_name | Value |
+------------------------+-------+
| lower_case_file_system | OFF |
| lower_case_table_names | 0 |
+------------------------+-------+
2 rows in set (0.00 sec)
#lower_case_table_names
如果此參數寫作1的話表示強制小寫，
即使創建的數據庫名字為大寫也會強制修改為小寫

?

測試：修改/etc/my.cnf文件--->>>>>>>>lower_case_table_names 將該參數置為1

?

?后續操作見代碼塊
