How do I know if I have successfully created a table (Python, Psycopg2)?

Question

I\'ve looked at the documentations but haven\'t found anything that lets me know if the last command i\'ve execute via cursor.execute(\"...\") is successful.

I\'m expect

Answer 1

I'd expect some kind of exception to be risen.
If everything went ok – the error code is 00000 and no exception will get risen.

In create table case, you can always double check:

try:
    cur.execute("SELECT ouch FROM aargh;")
except Exception, e:
    pass

errorcodes.lookup(e.pgcode[:2])
# 'CLASS_SYNTAX_ERROR_OR_ACCESS_RULE_VIOLATION'
errorcodes.lookup(e.pgcode)
# 'UNDEFINED_TABLE'
