c# - ALL or null with enums? -

i've noticed i've been doing inconsistently within same project. in places, i'll have enum option, , in others i'll have enum nullable type null value indicating (or no filter.)

i noticed when had write if (region != null && part != regions.all).

is there reason go 1 way or other?

where enums need specify either "all" or "null" type, go flag attribute , utilize bitwise & , |. much more flexible solution.

as making nullable type or having 1 alternative "all", think if makes sense you, see no problem it. prefer using flags.

c# enums null

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...
