For example, the default value of INT is NULL. Make sure that the INT variable have to initialized before using it further in calculations
What is the result of below query ?
DECLARE @Var INT
select @Var+GETDATE()+14.67 as TimeCalculationWithInt
Output is NULL
. Its because of the initial value of INT variable.
By assinging deafult value while declaration itself, we can avoid/prevent simple logical issues
DECLARE @Var INT = 0
select @Var+getdate()+14.67 as TimeCalculation
