In other words, you claim there is difference between
[biz.Record.sales_amount idx rec in biz.bizIterator()
if biz.Record.stateprov == "NJ"]
and
[rec.sales_amount for rec in biz.bizIterator()
if rec.stateprov == "NJ"]
in such context, isn't it?
Because I can't see any difference in accessing row attributes,
except referencing.
Tell me, if is there a difference in final effect, between
biz.setFieldVal(fld, val)
and
biz.Record.fld = val
please?
