MySQL Connector/C++ 1.1.5 宣告，此版本的二进制版本需要运用 Boost 1.54.0 编译。
凭证自己零星平台下载响应的版本。文件夹名字过长，将“mysql-connector-c++-noinstall-1.0.5-win32”改为“mysql”。
MySQL Connector/ODBC配置装备部署措施：
下面要配置装备部署vs2008的情景。
1. 名目属性页->C/C++->General->Additional Include Directories。将mysqlinclude目录削减进去。
2. 名目属性页->Linker->General->Additional Library Directories。将mysqllib与$MySQLbin目录削减进去。
3. 名目属性页->Linker->Input->Additional Dependencies。削减这两项mysqlcppconn.lib，mysqlcppconn-static.lib（mysqllib目录下的两个.lib文件）
4. 将mysqllib下的mysqlcppconn.dll文件与$MySQLbinlibmySQL.dll复制到windowssystem32文件夹下。
情景配置装备部署竣事。
数据库运用：
在衔接数据库以前，先建树一张表。 （着实这些可能在代码中实现，我这样是为了让测试代码尽可能精练易查错）
掀开操作台，输入mysql -u root -p，输入明码。
魔难之后已经有的数据库。（SQL语句开始加之';'展现赶快实施之后语句。）
mysql> show databases;
建树数据库
mysql> create database test;
运用数据库（这句不能加分号）
mysql> use test
魔难已经有的表
mysql> show tables;
建树表
mysql> create table testuser ( id INT, name CHAR(20));
插入数据
mysql> insert into testuser(id, name) values(1001, 'google');
mysql> insert into testuser(id, name) values(1002, 'kingsoft');
mysql> insert into testuser(id, name) values(1003, 'firefox');
如今在C++中查问这些数据
#include "stdafx.h"
#include <mysql_connection.h>
#include <mysql_driver.h>
#include <statement.h>
using namespace sql;
using namespace std;
void RunConnectMySQL()
{
mysql::MySQL_Driver *driver;
Connection *con;
Statement *state;
ResultSet *result;
// 初始化驱动
driver = sql::mysql::get_mysql_driver_instance();
// 建树链接
con = driver->connect("tcp://127.0.0.1:3306", "root", "123");
state = con->createStatement();
state->execute("use test");
// 查问
result = state->executeQuery("select * from testuser where id < 1002");
// 输入查问
while(result->next())
{
int id = result->getInt("ID");
string name = result->getString("name");
cout << id << " : " << name << endl;
}
delete state;
delete con;
}
int _tmain(int argc, _TCHAR* argv[])
{
RunConnectMySQL();
getchar();
return 0;

ResultSet * DatabaseMetaData::getTableCharset(const sql::SQLString& catalog, const sql::SQLString&schemaPattern, const sql::SQLString&tableNamePattern)
SQLString ResultSetMetaData::getColumnCollation(unsigned int columnIndex)
SQLString ResultSetMetaData::getColumnCharset(unsigned int columnIndex)
Connector/C++ 反对于 MYSQL_OPT_CONNECT_ATTR_ADD 选项，能接管一个 std::map 参数。(Bug #72697, Bug #18803313)

Connector/C++ 编译以及链接到 Connector/C 6.1.5 而不是 libmysql
Bugs 修复
MySQL_ResultSetMetaData::getColumnTypeName()returned UNKNOWN for LONG_BLOB fields. (Bug #72700, Bug #18803414)
Connector/C++ version-information methods have been revised to return the correct values. (Bug #66975, Bug #14680878)
Definitions for character sets and collations were added (utf8mb4 in particular). (Bug #71606, Bug #18193771)
;)
