Here the problem is that system.columns has cached value for number of
total table to iterate, and so it can skip something.
But anyway, this should be LOGICAL_ERROR, since ODBC bridge does two
queries:
- to system.tables and
- to system.columns
And if between this two queries the table will be removed, them there
will be no columns
