Before performing any operations with a database, a database object must be connected to a session by calling CTDatabase::Connect() method. The database should already have been created or added to the session.
// connect to a database
CTDatabase ADatabase(ASession);
try
{
ADatabase.Connect("MyDatabase");
}
catch (CTException &err)
{
printf("Connect to database failed with error %d\n", err.GetErrorCode());
}
When a database is connected to the session, it is considered "active". Use CTDatabase::IsActive() to check if a particular database is active.
When the database connection is no longer needed, it must be disconnected from the session by calling CTDatabase::Disconnect() method.
// disconnect from a database
try
{
ADatabase.Disconnect();
}
catch (CTException &err)
{
printf("Disconnect from database failed with error %d\n",
err.GetErrorCode());
}
