Count the number of employees who are there

[LudoP]

Hi,

I have a table as follow :

ID_EMPL / DATE_START / DATE_END / UNIT

I would have the count of employees who are present at a certain period (i.e in 2021, in june 2022, etc...) and in a certain unit.

Any idea on how to achieve this ?

Thank you in advance !
