Connector doesn't work (no replies)

Hello! I just started to code database manager to my project and I got problem. System is crashing when I try to create my database manager object. I tried to debug program and I found somethgin really wierd.

I have included all the headers and linked libraries so code goes throught the compiler.

Here is how I define driver and connection pointers:

sql::Driver* mSqlDriver;
sql::Connection* mSqlConnection;

I am initing driver this way:
void DatabaseManager::init()
{
mSqlDriver = get_driver_instance();
}

After I use my database manager method "connectPlug" the program crashes.

Here is the whole method:
void DatabaseManager::connectPlug()
{
if(isConnected == false)
{
mSqlConnection = mSqlDriver->connect("tcp://127.0.0.1:3306", "root", "asdfgh");
//mSqlConnection->createDatabase("DB_createdfromCpp");
}
else
{
OutputManager::getSingletonPtr()->writeToRunLog("System is already plugged to database!");
}
}

Debugger gives error message "Unhandled exception at 0x7855b690 in FPS login server.exe: 0xC0000005: Access violation reading location 0xcccccccc."

If I don't use the connect method and I close my program by pressing X to close my window, the program freezes for a short time and then there comes an error message of windows. If I comment those lines where I am getting driver and connection, the program works well. So what could be the problem? I tried to watch
some examples and they are doing same way. I am using VC2008 and I've linked connector dynamically (I have all the DLLs at the run directory).

link error only in release mode with Visual Studio 2008 (no replies)

Once again, a link error with an undefined symbol. I read the other reports, and mine looks different. The error message is the following:

1>Linking...
1> Creating library z:\PCdev\RepliKator2004\RK_Demo_2004\plugins\RepliKator04.bundle\contents\windows\RepliKator04.lib and object z:\PCdev\RepliKator2004\RK_Demo_2004\plugins\RepliKator04.bundle\contents\windows\RepliKator04.exp
1>RKConnector.obj : error LNK2001: unresolved external symbol __imp__sql_mysql_get_driver_instance@0


The interesting point is that the Debug version links just fine.

The Release version is set the same as the Debug version, except that the "Additional Library Directories" setting in the "Linker>General" property pane points to the release version of Connector/C++.

The release version of Connector/C++ was built following the build instructions and using the "Release" configuration of the project.

I am using Connector/C++ version 1.1.

My project is not an application, but a plugin for a third-party app.

In both Debug and Release mode, I use the default built version which I believe is the DLL version, not the static library version.

I really don't know how to approach this issue. I am definitely *not* a Windows developer, though I now have to do that job.


Any help or suggestion?

Thanks a million,

character set (no replies)

Hi,

I'm relatively new to mysql and the Connector/C++.
I'm using MySQL 5.1.45 with MySQL Connector C++ 1.0.5. I do compile under VC++.

I've created with no options database: d;
I've created a table with no options: t with only field f varchar(1);

I've created my program as follows:
string SQL = "INSERT INTO T1(f) VALUES(?)";
prep_stmt = con -> prepareStatement (SQL);
prep_stmt -> setString (1, "e");
int updatecount = prep_stmt -> executeUpdate();

And it works great.
Then I change
prep_stmt -> setString (1, "é"); // E with an accent...
and the execute update fails.

if I start the mysql prompt and do the insert statement it works fine.

Windows is using the latin1 characterset and mysql is using utf, so... I tried to change my table to use latin1, but still it fails.

Since I don't have to tell mysql what my characterset is when I connect, I think it expects unicode.

But I hope that I can tell in my C++ program that the data it get's is latin1 and that the table remains unicode. If not has anyone any idea on what is the best approach in this?

Thanks in advance,
Freek

Xcode Connector/C++ problem (no replies)

I'm new to mysql and was looking to learn/play around with c++ and mysql. I'm running
-mysql-5.1.45-osx 10.5-x86_64
- The include files are located in usr/local/mysql-5.1.45-osx10.5-x86-64
-mysql-connector-c++-10.5-osx10.5-x86-64bit
- The include and lib files are located in usr/local/mysql/include and usr/local/mysql/lib

-Mac OSX 10.6 (snow leopard)
-Xcode 3


I’ve been researching this issue for a few days and found others with the same problem but none of their solutions resolved mine and I can’t seem to figure out why.

I do the following.
1) Create new Carbon C++ Application
2) Add all the header files from usr/local/mysql/include and usr/local/mysql/include/cppconn into the project
3) Add all the libraries from usr/local/mysql/lib to target/testproject/Link Binary with Libraries
4) Modified the project settings by highlighting the project then clicking info as follows
- Added to Search Paths “Header Search Paths”
* usr/local/mysql-5.1.45-osx10.5-x86-64/include/**
* usr/local/mysql/include/**
- Added to Search Paths “Library Search Paths”
* usr/local/mysql-5.1.45-osx10.5-x86-64/lib/**
* usr/local/mysql/lib/**
-Under linking “Other Linker Flags” I’ve done a number of things here to be honest I’m not sure really what to do here.
* -lmysqlclient –lm –lz

My code looks as follows (I’ve omitted the default code that xcode adds when you create a carbon c++ application):

#include <Carbon/Carbon.h>
#include <TApplication.h>
#include “TWindow.h”
#include <sstream>
#include <memory >
#include <string>
#include <stdexcept>


#include <driver.h>
#include <connection.h>
#include <statement.h>
#include <prepared_statement.h>
#include <resultset.h>
#include <metadata.h>
#include <resultset_metadata.h>
#include <exception.h>
#include <warning.h>

Using namespace std;
Using namespace sql;


int main(int argc, const char *argv[]) {

Driver *driver;
try {
driver = get_driver_instance();
}
catch(SQLException &e){
cout<<”SQL Exception: ”<<e.what();
}
catch(runtime_error &e){
cout<<”Runtime Exception: ”<<e.what();
}
return 0;
}


The error message I receive when I build and run is below. So I was wondering if anyone who familiar with this issue or has successfully connected to a mysql database via c++ and xcode could help me out tell me what I’m doing wrong. Thanks in advance.

Retrieving UTF8 strings from DB (1 reply)

Hello,
I need to use ms vc++ with connector/c++. I can't, hovewer, get any utf8 string out of the db succesfully. Can someone point out to me what am i doing wrong or what could be missing in my approach?

First of all, my win32 app is unicode, i thought since my db is utf8 - unicode is the appropriate thing. I already wrote a function that converts e.g. mysql error messages to wchar_t* using mbstowcs_s.

When it came to converting actual string field data though, i saw that getString.c_str() points to a string which contains two-byte garbage in place of e.g. french or polish character. I thought _mbstrlen would count them properly, but no, it counts any multibyte character as two characters. Then i thought maybe mbstowcs_s would "glue" together these two bytes, but no, it treats them as two distinct characters.

What can i do to properly handle utf8 strings? Database must stay utf8 and i am already doing SET NAMES UTF8, which did not change a thing. Please assist.

Access violation - in release (1 reply)

Hi guys,

I've read quite a few posts now explaining how apps won't compile in debug mode, because the library was originally compiled in release mode. However, I'm only able to compile in debug mode - or, rather, the project compiles perfectly under both settings, only under release mode I get an access violation error message upon execution of my app, as most would get under debug mode.

How do I correct this? I naturally need to be able to compile properly under release mode.

Thanks.

PS. I'm using Visual Studio 2010, and I've installed the connector using the MSI.

Hey fellas.
I'm trying to connect my MySQL database using C++ connector.
I've done the next so far:
1.Installed the connector
2. Created a new project
3. Configured it as Active(Release)
4. In properties, under C/C++ -> General -> Additional Include Directories, I've added the connector's "include" folder
5. In Linker -> General -> Additional Libary Directories, I've added the "lib/opt" subfolder.
6. I've also added "mysqlcppconn.lib" under Linker -> Input -> Additional Dependencies
7/ I've copied "mysqlcppconn.dll" into the .exe folder

After all of this, I tried running this simple code:
---------------------------------------------------
#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)
{ sql:: driver *driver;
sql::Connection *con;
driver = get_driver_instance();
con = driver->connect("tcp://127.0.0.1:3306", "root", "root");
}
----------------------------------------------------

But I just keeping getting this error:
"The application was unable to start correctly (0xc000007b)"

Any ideas ?
Thanks ahead

Hi,

I'm looking at my options for changing the c++ library that I use to acees my mySql databases, I'm currently using the Rude library which is very good but I'm coming up against some limitations with it.

The main thing that I want to be able to do but cant is to determine the column types and names from a dynamic query, effectively allowing the user to write the query and my program to format the results

I know this can be done with MySql++ does the same go for MySQL Connector?

Is MySQL Connector generally the direction to go in rather than MySql++ ?
