- Declare the datatypes used to determine transaction element data (prepared statement/adhoc query string) on a generic level in SQLOperation.h - Implement variable SQL element data for SQLQueryHolder class so it can execute both prepared statements and adhoc queries - Make MySQLConnection::Query for adhoc queries return pointer to type instead of an autopointer, the autopointer is now applied on higher level code just like the function for querying prepared statements --HG-- branch : trunk
