mysql client api 的封裝

阿新 • • 發佈：2018-12-15

前言

這幾天，在測試程式中要用mysql client api 去資料庫插入記錄和查詢記錄。
好久不用mysql client api, 沒有封裝好的存貨。只能用api直接幹活。
前天閒下來了，將mysql client api的使用封裝成類，對執行sql語句的操作封裝了成員函式，實現庫的建立，表的建立，use database, 記錄的增刪改查. 等下次再用到，就直接用這個類幹活了。

實驗環境

debian8.8 + mysql5.5.60-0+deb8u1

前置任務

如果連線的不是本地mysql資料庫，需要在資料庫改使用者許可權，使遠端訪問資料庫成為可能。
這活，如果是在工作中，已經由運維人員搞好了。
如果是自己做實驗，這步要自己做。

# 在debian8.8中安裝mysql 
aptitude install mysql-server mysql-client

# 登陸mysql客戶端 ，連線本地資料庫
mysql -h 127.0.0.1 -u root -p 

# 如果不是迴環ip訪問, 需要在配置檔案中繫結允許訪問的客戶端ip
vi /etc/mysql/my.cnf 
# bind-address          = 127.0.0.1 
# ref https://dev.mysql.com/doc/refman/8.0/en/server-options.html 
bind-address            = * 

# 重啟mysql服務 
/etc/init.d/mysql restart 

# 修改mysql配置之後, 就可以用迴環地址或者本地IP地址登陸msyql客戶端工具了
mysql -h 192.168.11.140 -u root -p

建立供遠端訪問的mysql使用者

mysql> select host,user,password from mysql.user;

mysql口令的使用者長度是定長的
mysql> create user remote_user identified by password '12345678901234567890123456789012345678901'; 
Query OK, 0 rows affected (0.00 sec) 

給剛建立遠端使用者設定所有資料庫操作的許可權.設定完後，就可以用本地活遠端用伺服器的IP來登陸mysql了
實際的工作資料庫，運維人員都設定好了，我們不管.
grant all privileges on *.* to remote_user identified by '12345678901234567890123456789012345678901';

其他一些可能用到的mysql客戶端的命令. 其實到了這步，就可以在windows上搞個圖形化的資料庫工具來做實驗了.
mysql> SHOW DATABASES;   //顯示資料庫
mysql> USE my_db         //進入資料庫
mysql> SHOW TABLES;      //顯示錶
mysql> DESCRIBE mytable; //顯示錶結構
mysql> CREATE DATABASE abccs;    //建立一個數據庫
mysql> select version();  // 顯示資料庫版本
