Hi,
I created a computed column in a table of SQL Server 2005. The column name is DaysOver. The formula in the Computed Column Specificaion is [Date1]-[Date2]. The type of the column is empty. Does this column always return an integer? Because I use it in the SQL select as following:
select * from MyTable where DaysOver > 10
And the returned query has the correct rows. But what if one of the DateTime columns (Date1 or Date2) is NULL? What will be returned?
