c# - Casting null doesn't compile -

accidentally @ work wrote next line of code:

string x = (object) null; // var x = (object)null , changed var string instead of // object x = null;

this gave me compilation error similar this: can't cast source type object target type string

why? isn't null bunch of zeros pointing "nowhere" memory address, no matter type is?

the question here "why compiler not take business relationship fact knows assigned value constant reference known null?"

the reply is: why should it? what's compelling benefit of taking info account? deliberately said "i want look treated though of type object", , can't assign value of type object variable of type string. what's benefit of allowing in case?

the code seems me highly bug; certainly compiler should telling rather allowing it.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
