Re^2: Implementing named infix operators with parser hook?

Yes I did. :)

I'm using objects.

I have a very good solution yet, using indirect method calls and constants as operands.

col BETWEEN 1,2

I just need an alternative for the cases where the LHS is not a constant, which is rare in most SQL statements.

Maybe its time to show a proof of concept...

Don't you mean it's rare for LHS to be a constant in SQL statements. Or is the problem that 'rare in most' as opposed to just saying 'rare' can be satisfied by a 51% hit rate (most can be 50.5%, with rare being say 1.5% inside that, but by saying nothing about the other 49.5% allows them all to be hits). One has to be rigorous with verbal expression of statistical propositions. One world, one people	[reply]

Rare = significantly less than 5 %. Columns are represented as Perl constants in my DSL. Cheers Rolf under _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery FootballPerl is like chess, only without the dice}	[reply]
