First of all what is a Scalar-valued function?

A scalar function in SQL Server is similar to the generally accepted meaning function, a function is defined by the variables (parameters) with some operation on them and the resulting value is the return value of the function.

    function(x,y)=x+y defines a scalar function that returns a value which is the sum of x and y.
