How do Monks programatically construct SQL selects.

I don't.

Indeed. It's interesting how this particular question comes up again and again. Yes, SQL queries can be generated, but when you start using a normalized schema auto-generated queries tend to fall down. In order to get good, repeatable performance it is essential to write well behaved queries (i.e. queries where the JOIN and/or WHERE clauses use appropriate indexes) as a single badly written query can bring even very powerful hardware to its knees...

This is one of the reasons why I always try to use stored procedures where I can.

[GotToBTru]: oh I know what it is .. but it is a number only slightly useful to me and of no possible use to our customer
[MidLifeXis]: Whew - you just saved the free world. <o)
[GotToBTru]: i guess it's a placeholder, the code will only fill it in if there is nothing else to use
[GotToBTru]: but then .. if you have nothing to say, why not say nothing?
[MidLifeXis]: I have a user who has a lot of say on how some of our processes work that abhors significant blanks. Perhaps that is a part of it. A not-so-obvious "this space intentionally left blank" indicator.
[MidLifeXis]: On the back end, however, that doesn't mean that i have to use that value to indicate "undefined", no matter how much he thinks I should.
