Open MS Access file in Linux - database

Question

I'm trying to open MS Access database file with QT in Linux.
So, I have installed Easysoft MS Access ODBC Driver with unixODBC. There is my odbc.ini file:
[Easysoft ODBC-ACCESS]
Description = MS Acess db driver
Driver = /usr/local/easysoft/access/lib/libesmdb.so
Setup = /usr/local/easysoft/access/lib/libesmdbS.so
and there is odbcinst.ini file:
[ACCESS_SAMPLE]
Driver = Easysoft ODBC-ACCESS
mdbfile = /home/user/personal_base.mdb
Also, I have installed odbc plugin for qt:
sudo apt-get install libqt4-sql-odbc
Now how can I open mdb-file with Qt in Linux?
In MS Windows I do it such way:
bool createConnection()
{
QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
db.setDatabaseName("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DSN='';DBQ=C:/personal_base.mdb");
if (!db.open()) {
QMessageBox::warning(0, QObject::tr("Database Error"), db.lastError().text());
return false;
}
return true;
}
I try to change db.setDataBaseName to
...
db.setDatabaseName("Driver={Easysoft ODBC-ACCESS};DSN='ACCESS_SAMPLE'");
...
But it returns an error:
[unixODBC][Driver Manager]Data source name not found, and no default driver specified QODBC3: Unale to connect
What's the matter?

Answer 1

Here is some code that I use for building the proper DSN for connecting to SQL Server from Mac, Linux, and Windows. I believe that your connection string isn't correct in your code. Perhaps it will help get you started.
QString SQLServerProvider::buildDSN(QString server, QString database, QString username, QString password)
{
#ifdef Q_WS_MACX
QString dsn = QString("DRIVER=/usr/local/lib/libtdsodbc.so;SERVER=%1;TDS_VERSION=8pClient;DATABASE=%2;PORT=1433;UID=%3;PWD=%4;").arg(server).arg(database).arg(username).arg(password);
#endif
#ifdef Q_WS_X11
QString dsn = QString("DRIVER={FreeTDS};SERVER=%1;TDS_VERSION=8.0;PORT=1433;DATABASE=%2;UID=%3;PWD=%4;").arg(server).arg(database).arg(username).arg(password);
#endif
#ifdef Q_WS_WIN
QString dsn = QString("DRIVER={SQL SERVER};SERVER=%1;DATABASE=%2;UID=%3;PWD=%4;").arg(server).arg(database).arg(username).arg(password);
#endif
return dsn;
}
I know that you are trying to connect to a Microsoft Access database, but perhaps if you replace FreeTDS and a few other paraneters in the Q_WS_X11 part, that will work for you. I have not used Easysoft ODBC-ACCESS before so I'm not 100% sure of how DSNs should be formatted for this driver. Have a read here if you haven't already as it explains how to test ODBC DSN connections using isql. If you need further assistance, let me know and I'll see what I can do to help.

Try changing your DSN-Less connection to look :-
Driver=/usr/local/easysoft/access/lib/libesmdb.so;mdbfile=/home/user/personal_base.mdb
Add your your machines library path :-
export LD_LIBRARY_PATH=/usr/local/easysoft/lib:/usr/local/easysoft/access/lib:/usr/local/easysoft/unixODBC/lib:$LD_LIBRARY_PATH
Finally email support#easysoft.com and ask them for the latest version of the driver.
