[python-sybase] NumericType not hashable?

[Harri P. <har...@tr...>]

Hi,

By the looks of it, NumericType is not python hash table friendly.

That means that something like:

c.execute('select id, limit_id, name from Sublimit_cvt')
rows = c.fetchall()
for row in rows:
    id, limit_id, name = row

c.execute('select id from MyTable')
rows = c.fetchall()
for row in rows:
  id = row[0]
  print map[id]


will fail if id is of type AutomaticID in Sybase.

I'm not sure if this is required by DB API, but I think it violates the
principle of least surprise.

My workaround was to force a conversion to string, so my code now reads
map[str(id)]. But maybe NumericType should be modified to act as any number
when used as a hash key?  Any opinions?
