C++: Can I write a template class that derives from T? -

i'm not sure how word in english, want this:

template <class t> class derived: public t { blah };

where basically, have template class, i'm deriving new class class specified in template? i.e. wouldn't know class @ compile time.

is possible? if so, semantics this?

for example, i'm trying write "parent" class. purposes of example, let's it's tree parent. tree parent, tree (so inherits tree), has vector of references kid trees.however, parent class doesn't have tree; class, such write like:

parent<tree> treeparent; parent<shrub> shrubparent;

yes. possible. seek doing that.

i wouldn't know class @ compile time.

i think, mean "i wouldn't know class @ time of defining class template."

by time compile, you've defined class template, , used in code, passing template argument it, means know class (i.e template argument) @ compile time. if don't know class used base, cannot compile code.

c++ templates inheritance base derived

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...
