hello,

I have 1 table called project with 40 records including project_Code, Project_start_date and project_finish_date field.
My question is how to find the record who takes long time.
If Project_finish_date is NULL he has to appear because the project is not finish.

Here is my query but is not working.
SELECT code_project
from project
where datediff(year, date_fin, date_debut)

Thank you for your help

1. you got the datediff parameter wrong. it should be datediff(year, date_debut, date_fin)
2. where clause need a logical comparison, the datediff() only returns a value

try


select *
from   projects
order by datediff(year, date_debut, isnull(date_fin, getdate())) desc
