qlikview date and month

Architect — Sun, 25 Apr 2021 05:13:08 GMT

HI, I have two questions-

1>There is a table with 2 columns employee_name and DOB
for any given day how to determine how many employees have birthdays in the coming 30 days?

2> For any given day how to determine what months we may have in the coming 30 days?
say today is April 25th and in the coming 30 days, we have both April and May.

If you don't want to adjust your data model then you could try this.

No of birthdays next 30 days
count({<DOB={"=Age('$(vL.Today)',DOB)<Age('$(vL.Today)'+30,DOB)"}>}DOB)

Months in next 30 days
IF (month( '$(vL.Today)')=month( '$(vL.Today)'+30),
Date( '$(vL.Today)', 'MMMM'),
date( '$(vL.Today)', 'MMMM')& ', '& date( '$(vL.Today)'+30, 'MMMM')
)

@Vegar thank you so much for the answers.

I always struggle with this date function. if you can guide me to any document or link that can explain this function clearly, would be of great help.

I don't have a good for you at the moment, but I see that a lot of people missunderstand the date() function. It is a formating function that presents a numeric value as a date in default or specified format. In my case 'MMMM' which is the full month name. It is important to remember that the underlying numeric value will not change when using date().

Consider this
The timestamp '2021-04-25 09:57:00' it has the numeric value of 44311.414583333.
The date '2021-04-25' has the numeric value of 44311.
Using Date() on a timestamp will not change the underlying numeric value. So Date('2021-04-25 09:57:00') will present the string '2021-04-25', but the numeric value will still be 44311.414583333

To convert a timestamp or date into another value I recommend looking into the date and times functions offered in QlikView
