Which function performs the opposite function of CEILING function in SQL Server?

Posted By :Abhisek Panda     Posted Date :February 26, 2010    Points :10   Category :Sql Server 
FLOOR function performs the opposite function of CEILING function in SQL Server.

FLOOR rounds up a non integer value to the next least integer while CEILING rounds up the non integer values to the next highest integer.

What is the use of COALESCE function in SQL Server ?

Returns the first not null expression among its arguments.

If X is Null then It'll check for Y,

What is the use of CEILING function?

The CEILING function does the opposite of FLOOR function. It returns the smallest integer greater than the value you specify.



It will output 401.

NOTE:- It rounds up the non-integer number to the next highest value. If you enter negative value, it will return the lower absolute value.


It will output 400. (More...)

What is Method Overriding? How to override a function in C#?

Use the override modifier to modify a method, a property, an indexer, or an event. An override method provides a new implementation of a member inherited from a base class. The method overridden by an override declaration is known as the overridden base method. The overridden base method must have the same signature as the override method.
You cannot override a non-virtual or static method. The overridden base method must be virtual, abstract, or override. (More...)

Define precondition and post-condition to a member function.

A precondition is a condition that must be true on entry to a member function. A class is used correctly if preconditions are never false. An operation is not responsible for doing anything sensible if its precondition fails to hold.
For example, the interface invariants of stack class say nothing about pushing yet another element on a stack that is already full. We say that isful() is a precondition of the push operation.

A post-condition is a condition that must be true on exit from a member function if the precondition was valid on entry to that function. A class is implemented correctly if post-conditions are never false.
For example, after pushing an element on the stack, we know that isempty() must necessarily hold. This is a post-condition of the push operation. (More...)

Difference between a sub and a function.

A Sub Procedure is a method will not return a value
-A sub procedure will be defined with a "Sub" keyword
Sub ShowName(ByVal myName As String)
Console.WriteLine("My name is: " & myName)
End Sub
-A function is a method that will return value(s).
-A function will be defined with a "Function" keyword
Function FindSum(ByVal num1 As Integer, ByVal num2 As Integer) As Integer
Dim sum As Integer = num1 + num2
Return sum
End Function (More...)

Explain Virtual Function in C#.

Virtual functions implement the concept of polymorphism are the same as in C#, except that you use the override keyword with the virtual function implementaion in the child class.

The parent class uses the same virtual keyword. Every class that overrides the virtual method will use the override keyword.

class Shape{
public virtual void Draw()
{ Console.WriteLine("Shape.Draw") ; }
class Rectangle : Shape{
public override void Draw()
{ Console.WriteLine("Rectangle.Draw"); }
} (More...)
