You are correct sir there doesn't appear to be support for isnan or infinite:

I'll try something far less efficient, possibly a lambda expression on table
column. Anyways, thanks for root causing the issue.

So this is probably a numexpr issue. There doesn't seem to be an isnan()
implementation [1]. I would bring it up with them. Sorry we can't do more.
Be Well

I get the same error if I use:
bad_vols = tbl.getWhereList('volume == nan')
bad_vols = tbl.getWhereList('volume == NaN')

Have you tried simply doing:
'volume == nan' or
'volume == NaN'

Hello All,
I am trying to determine if there are any NaN values in one of my tables, but
when I queried for numpy.nan I received a NameError. Can any tell be the best
way to search for a NaN value? Thanks!
In [7]: type(np.nan)
Out[7]: float
In [8]: bad_vols = tbl.getWhereList('volume == %f'
