Storing BLOB with C++

First of all, I have to admit that neither my English, nor my C++ Knowledge
is very profound.

So, I'm using a C++ wrapper class "around" mysql++, which alowes me simple
access to MySQL DB.

I have to put binary Objects to my DB, like *.jpg.

I read
http://www.mysql.com/documentation/mysql++/4_Tutorial.html#SECTION0316100000
0000000000
(possible line break by mailer)
but it didn't help me, perhaps the C++ is a bit to tricky.

I want to read the file like this:

#include <string>
#include <iostream>
#include <fstream>

 ifstream inFile;   ofstream outFile;

 std::string readme = "Demofile.xxx";
 std::string writeme = "Demofile.bak";

 inFile.open(readme.c_str(), ios::binary);

if (!inFile)    {
      // Error
 }

outFile.open(writeme.c_str(),ios::binary);
if (!outFile)  {
      // Error
   }

// a little test to copy Filebuffers

 char cLetter='q';
 int num=0;
   while (inFile.get(cLetter))
   {
     num++;
    outFile.put(cLetter);
   }

 inFile.close;
 outFile.close;
 cout << num << " number letters copied";

// End of Source

ok, now my question:
Can I simply join a long SQL-String ( type stringstream or std::string ) ,
where I put my File-Data as variable?
I think I have to Escape some characters therefor.

My proposal: ( adapted from some newsgroup )

std::string escape(std::string  toEscape)
{
    string  toReturn;
 // characters to escape: ->      \ ' ; and "    , \ has to be like \\ and "
like \" in C++
 std::string separators="\\'\;\"";
 for ( int i=0; i < toEscape.length(); ++i) {
        if ( find(separators.begin(), separators.end(), toEscape[i]) !=
separators.end() ) {
            toReturn += '\\';
        }
        toReturn += toEscape[i];
    }
    return toReturn;
}

I read in a PHP manual, that the 0-character (Sero) has to be escaped
 "addslashes()")
how?


So I hope, this is a not to long question and somebody  can help me.

Many thank's for your reading my question!
