Обсуждение: parser enhancement request for 6.5

I have a problem with Access97 not working properly when entering new
records using a sub form, i.e. entering a new order/orderlines or master and
detail tables.  The problem is caused by a SQL statement that Access97 makes
involving NULL.  The syntax that fails is "column_name" = NULL.  The
following attachment was provided by -Jose'-.  It contains a very small
enhancement to gram.y that will allow Access97 to work properly with sub
forms.  Can this enhancement be added to release 6.5?

 <<gram.patch>>
Thanks, Michael

I recall discussing this earlier, and after the obligatory objection
that this is non-standard (a la everything M$) it should be OK to do it.
I could have sworn that I'd made this fix, but can't see it in current
sources and can't see any evidence that it ever was :(

Will enable this for v6.5, with the proviso that it is fair game for
removal if it ever conflicts with other SQL parsing needs.

Applied.
