mysql connector c++ 1.1 API初步體驗

1，常用的頭文件

#include

#include

#include

#include

#include

#include

2，創(chuàng)建連接

#define DBHOST "tcp://127.0.0.1:3306"

#define USER "username"

#define PASSWORD "pwd"

sql::mysql::MySQL_Driver *driver;

sql::Connection *con;

sql::Statement *stmt;

driver = sql::mysql::get_mysql_driver_instance();

con = driver->connect(DBHOST, USER, PASSWORD);

3，選擇要使用的database的名字

con->setSchema("database_name");

4，設置連接的屬性，例子是設置連接的字符集

con->setClientOption("characterSetResults", "utf8");

5，判斷連接是否建立成功

if(con->isValid()){

std::cout << "connected!" << std::endl;

}

6，執(zhí)行insert語句

sql::PreparedStatement* pstmt;

std::string sqlOp="insert into user(name,nickname,password, phone) values(?,?,?,?)";

pstmt=con->prepareStatement(sqlOp);

pstmt->setString(1,"李四2");

pstmt->setString(2,"aaaa男2");

pstmt->setString(3,"aaaa!");

pstmt->setString(4,"123123");

pstmt->execute();

7，執(zhí)行查詢語句

sql::Statement *stmt;

sql::ResultSet *res;

std::string qry = "select * from user";

stmt = con->createStatement();

//選擇使用的數(shù)據(jù)庫的名字

stmt->execute("use cloud_disk");

res = stmt->executeQuery(qry);

while(res->next()){

std::cout << res->getInt(1);

std::cout << res->getString(2) << std::endl;

}

8，釋放資源

除了sql::mysql::MySQL_Driver *driver指針，都需要手動調(diào)用delete釋放

delete res;

delete stmt;

delete con;
