I'm having a bit of issues with trying to run a compiled program that uses the MySQL connector, in C++. It compiles just fine, but when running it, it'll crash immediately - seemingly so on the line that's meant to connect. I've set up all additional libraries, dependencies, pre-processors and linker inputs, and I'm using the Release solution configuration. I am running Microsoft Visual Studio 2012.
The error I'm getting is the following: Unhandled exception at 0x6E69AF48 (msvcr90.dll) in MyLittleSQL.exe: 0xC0000005: Access violation reading location 0x00000024.
And the call stack:
MyLittleSQL.exe!main() Line 24 C++
MyLittleSQL.exe!__tmainCRTStartup() Line 536 C
Line 24 is:
con = driver->connect("tcp://127.0.0.1:3306", "sepples_su", "easy");
And the full source code is:
#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;
}
This is actually one of the examples taking from the Connector documentation, but I wanted to make sure it wasn't my own fault first.
Any help here would be appreciated, thank you.
