Comparing date in set-analysis doesn't work

[#1]

I have no clue why this work:

= if ([Unavailable Start Date] < $(vEndDate4), 'true', 'false')

And this also:

( {$< [WorkItem
Enddate] = {">=$(vBeginDate4)<=$(vEndDate4)"}
>} [WorkType Todo] )

But this doesn't:

count( {$< [Unavailable Start Date] = {">=$(vBeginDate4)<=$(vEndDate4)"} >} [Unavailable
Start Date] )

Hi,

try this

count( {$< [Unavailable Start Date] = {">=$(=vBeginDate4)<=$(=vEndDate4)"} >} [Unavailable Start Date] )

If not working check whether the date format in variables and dimension are same.

Jagan.

It doesn't work.

How do I check? Because doesn't this depens on the formatting of listbox?

When i put no formatting on the listboxes their appearence is not the same.

[Unavailable Start Date] -> displays as a date

vBeginDate4 -> as a number

Gerry - you got it! The problem is caused by the fact that the two values are formatted differently, and it's important in Set Analysis.

So, for example:

if ([Unavailable Start Date] < $(vEndDate4), 'true', 'false') works because QlikView evaluates the expression, using the numeric value of the date field, and comparing it to the numeric value of the variable.

count( {$< [Unavailable Start Date] = {">=$(vBeginDate4)<=$(vEndDate4)"} >} [Unavailable
Start Date] ) - doesn't work, because  the field is formatted as a date, and the variables are formatted as numbers, and that's an incorrect syntax in Set Analysis.

I'd suggest one of the two following solutions:

1. Format the variables as Dates:

count( {$< [Unavailable Start Date] = {">='$(=date(vBeginDate4))'<='$(date(vEndDate4))'"} >} [Unavailable
Start Date] )

2. Re-work the condition into a Boolean condition that can compare the field with the variable numerically:

count( {$< [Unavailable Start Date] = {"=(num([Unavailable Start Date])>=$(vBeginDate4) and num([Unavailable Start Date])<=$(vEndDate4))"} >} [Unavailable Start Date] )

can't guarantee the syntax 100%, I only typed it here with no validation...

best,

Hi,

try this

=count( {$< [Unavailable Start Date] = {">=$(=Date(vBeginDate4))<=$(=Date(vEndDate4))"} >} [Unavailable Start Date] )

If not working check whether the date format in variables and dimension are same.

Thanks Jagan and Oleg,

I used this expression:

=count( {$< [Unavailable Start Date] = {">=$(=Date(vBeginDate4))<=$(=Date(vEndDate4))"} >} [Unavailable Start Date] )

And it works fine.
