我在嘗試運行使用C++中的MySQL連接器的編譯程序時遇到了一些問題。它編譯得很好,但是在運行它時,它會立即崩潰 - 看起來就像是要連接的線路一樣。我已經設置了所有額外的庫,依賴項,預處理器和鏈接器輸入,並且正在使用發佈解決方案配置。我正在運行Microsoft Visual Studio 2012.從Visual Studio運行MySQL Connector/C++時崩潰
我收到的錯誤如下: MyLittleSQL.exe中的0x6E69AF48(msvcr90.dll)未處理的異常:0xC0000005:訪問衝突讀取位置0x00000024。
而且調用堆棧:
MyLittleSQL.exe!main() Line 24 C++
MyLittleSQL.exe!__tmainCRTStartup() Line 536 C
第24行是:
con = driver->connect("tcp://127.0.0.1:3306", "sepples_su", "easy");
而完整的源代碼是:
#include <stdlib.h>
#include <iostream>
#include "mysql_connection.h"
#include "mysql_driver.h"
#include <cppconn/driver.h>
#include <cppconn/exception.h>
#include <cppconn/resultset.h>
#include <cppconn/statement.h>
using namespace std;
int main(void)
{
try
{
sql::Driver *driver;
sql::Connection *con;
sql::Statement *stmt;
sql::ResultSet *res;
/* Create a connection */
driver = get_driver_instance();
con = driver->connect("tcp://127.0.0.1:3306", "sepples_su", "easy");
/* Connect to the MySQL test database */
con->setSchema("test");
stmt = con->createStatement();
res = stmt->executeQuery("SELECT 'Hello World!' AS _message");
while (res->next())
{
cout << "\t... MySQL replies: ";
/* Access column data by alias or column name */
cout << res->getString("_message") << endl;
cout << "\t... MySQL says it again: ";
/* Access column fata by numeric offset, 1 is the first column */
cout << res->getString(1) << 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;
}
這實際上是採取了一個例子連接器文檔,但我想確保它不是我自己的錯。
任何幫助在這裏將不勝感激,謝謝。
使用Visual Studio 2012編譯連接器的DLL嗎?使用不同編譯器編譯的庫會導致類似崩潰。 –
有沒有辦法檢查這個?該DLL通過mysql.com上的存檔編譯發貨。 – mtaanquist
您確定您使用的是最新版本? –
