why not:
int smth = sqlite3_step (statement2);
while( smth == SQLITE_ROW )
{
printf( "\n command= %s result code = %d \n", command, smth );
smth = sqlite3_step (statement2);
}
so that it will work no matter how many rows

See http://www.sqlite.org/c3ref/column_blob.html

You are using prepare for each command...
