我已经将centos6.4用作服务器(mysql)以及客户端。我已经使用代码块16.01来编译以下代码。
#include <stdlib.h>
#include <iostream>
#include <mysql_connection.h>
#include <cppconn/driver.h>
#include <cppconn/exception.h>
#include <cppconn/resultset.h>
#include <cppconn/statement.h>
using namespace std;
int main(void)
{
cout << endl;
cout << "Running 'SELECT 'Hello World!' "
<<"AS _message'..." << endl;
try {
sql::Driver *driver;
sql::Connection *con;
sql::Statement *stmt;
sql::ResultSet *res;
/* Create a connection */
driver = get_driver_instance();
con = driver->connect("tcp://serverora11gr2.db.net:3306", "rahul", "rahul");
/* Connect to the MySQL test database */
con->setSchema("inventory");
stmt = con->createStatement();
res = stmt->executeQuery("SELECt * from tablestaffregistration");
while (res->next()) {
cout << "\t... MySQL replies: ";
/* Access column data by alias or column name */
cout << res->getString(1) << endl;
cout << "\t... MySQL says it again: ";
/* Access column data by numeric offset, 1 is the first column */
cout << res->getString(2) << endl;
}
delete res;
delete stmt;
delete con;
} catch (sql::SQLException &e) {
cout << "# ERR: SQLException in " << __FILE__;
cout << "(" << __FUNCTION__ << ") on line "
<< __LINE__ << endl;
cout << "# ERR: " << e.what();
cout << " (MySQL error code: " << e.getErrorCode();
cout << ", SQLState: " << e.getSQLState() << " )" << endl;
}
cout << endl;
return EXIT_SUCCESS;
}
,发现以下错误:- [rahul @ client64ora11gr2调试] $ ./mysqlcppconn_2
Running 'SELECT 'Hello World!' AS _message'...
Character set 'utf8mb4' is not a compiled character set and is not specified in the '/usr/share/mysql/charsets/Index.xml' file
# ERR: SQLException in /opt/project/codeblocks/c++/mysqlcppconn_2/main.cpp(main) on line 57
# ERR: Can't initialize character set utf8mb4 (path: /usr/share/mysql/charsets/) (MySQL error code: 2019, SQLState: HY000 )
我从https://dev.mysql.com/doc/connector-cpp/1.1/en/connector-cpp-examples-complete-example-1.html那里获得了这段代码
如何克服这个问题。
我还在链接器设置和编译器“ / usr / include / cppconn”和链接器搜索:“ / usr / lib64 / mysql”的搜索目录中的链接器设置和路径中添加了“ mysqlcppconn”和“ mysqlclient”
