where date(floor(CalendardateField))>date(today())

One suggestion:

While comparing(=,>,<), there is no point using a formatting function like date(), because that doesn't change the underlaying number and hence no change in comparison result. Therefore, we should avoid using such formatting functions during comparison to exclude unnecessary operation.

Note: This doesn't hold true while we compare in general Set Analysis, because there it's possibly a text-like comparison.

Hi,

my Datefield means DATUM

This means,

Load Datum

From <> where Datum< Today();

Right?

Hi Tresesco,

I have gone through few cases where DateField is in text format then comparing with today() date.

You have to do formating for comparision because your date field is in text and result of today() is different.

Sometime you have to use Date#() also to execute comparision properly.

So my suggestion is if necessary use formatting.

Hi,

That(text comparison) I already mentioned. However, the way you showed "where date(floor(CalendardateField))>date(today())" doesn't definitely tell that it could be a text field, otherwise floor() would not work there. And if you use date#(), it would again get converted to a proper date field with numeric representation at the back. There too, using date() would be an over-head I guess. Isn't it so?
