I am trying two update a column where the difference between two values are <= 5.
My code :
set UreStasie1Klas1 = SubQuery.TelLyne
from Loggerdata as tn
select Datum, MaksStasie1,MinStasie1,Stasie1
, count(Stasie1) as TelLyne
where (MaksStasie1 – Stasie1 <= 5 )
group by Datum ) as SubQuery
on SubQuery.Datum = tn.Datum
However I get an error message : Msg 102, Level 15, State 1, Line 8
Incorrect syntax near '–'.
How do I subtract two values from each other in the above query?
How do I calculate the absolute difference?
I am using SQL Community 2017.
