I have a database that tracks the service calls we do. In the database
are abstime values for:
dateentered
dateclosed
dateassigned
datecontacted
I have perl scripts managing the interaction between our web site and the
database.
My question is: what is the SQL statement that will allow me to find:
1) a list of the calls where the difference between the dateentered and
dateclosed is less than (say) 3 days.
I have tried:
Select * from servicecall where (dateentered <#> dateclosed) #<= 3 days;
Select * from servicecall where (dateclosed - dateentered) #<= 3 days;
Select * from servicecall where (dateentered <#> dateclosed) #<= @3 days;
Select * from servicecall where (dateclosed - dateentered) #<= @3 days;
Any suggestions?
Thanks.
