Hello, I've got the same problem than mazah_82
At the end of the block, the program doesn't terminate correctly: The program displays (cout) 1 2 But it stops before displaying 3
Here is my code:
-------------------------------- Connection & conn = BdParam::getConnexion(); // see later: I explain how // to connect
// Creation de la requete à partir de la connexion Query query = conn.query(); query << "select BAL_LAT " << "from BALISE " << "where BAL_PK_NOM_BALISE = '" << arNomBase << "'";
// execution de la requete Result res = query.store();
cout<<"1"<<endl;
if (res.size() > 0) {
Row row = res.at(0);
double l = row.at(0);
cout<<"2"<<endl; } cout<<"3"<<endl;
....
----------------------------------- How do I create the connection to the database ? :
I've got a static class "BdParam", which defines a static Connection (con)
----------------------------------- // declaration of the connection Connection BdParam::con=Connection(use_exceptions);
// method implementing the connection Connection & BdParam::getConnexion() {
BdParam::con.connect("database", "host", "user", "password"); return BdParam::con; }
Is anyone able to notice I made a mistake or not? Thanks a lot for replying, please.
