Hi All,
As part of my ongoing quest to understand grammar files, I've been trying to
implement BETWEEN SYMMETRIC/ASYMMETRIC.
I've attached my current work. Can someone please look and tell me if I'm
on the right track? With this patch, I get parse errors after BETWEEN if I
go:
SELECT 2 BETWEEN ASYMMETRIC 1 and 3;
or
SELECT 2 BETWEEN SYMMETRIC 1 and 3;
So it doesn't seem to be working - I don't know why!!
Don't look at the NOT BETWEEN stuff - I've not done it yet.
I was forced to put SYMMETRIC and ASYMMETRIC as reserved words - anything
else seemed to give shift/reduce errors. Is there anything I can do about
that?
