When this code would be executed, st will be a valid command object. Initializing st in this fashion already sets the connection properties for the command object, that's the only advantage. U dont have to set the connection properties for the st object explicitly as it is done by the con object for you automatically...

This statement is used to get the reference of a forward only cursor which is capable of doing any query operation from the front end tool.

Well this line of code assigns reference st to a Statement object.
Now you can use this object to execute SQL queries.
