Inserting PNG into Database - Escaping String

[bhavya]

Hi all,

I am trying to insert a PNG image into a mysql database using Qt.
I am facing the problem to escape special characters into image and
I cannot find any function in Qt related to this.

I am attaching the piece of my code for this.

QByteArray ba;
    QBuffer buffer(&ba);
    buffer.open(QIODevice::WriteOnly);
    image->save(&buffer, "PNG");  //image is a QImage
 
   QString sql = QString( "INSERT INTO myTable ( blob ) VALUES ( %1 )").arg( ba.data() )

QByteArray ba;
    QBuffer buffer(&ba);
    buffer.open(QIODevice::WriteOnly);
    image->save(&buffer, "PNG");  //image is a QImage

   QString sql = QString( "INSERT INTO myTable ( blob ) VALUES ( %1 )").arg( ba.data() )

To copy to clipboard, switch view to plain text mode 

and when exec() this sql query, I get an error. Most probably I need to escape `ba.data()'
plz help
