    1. if half of the values of n does not give remainder 0 then the higher values preceding n/2 will also not give reminder zero and it also improves performance of the code as you are executing the condition for half of the length.
      hope u got it.

      1. Can you please explain how it worked for 2.As per my understanding i and n both are 2 so flag will be 0 hence not prime. Please correct if i am wrong

  1. hai Neeraj Mishra you are doing a grate job i like your programming .but i have one doubt in prime number program by plsql .why we take n/2 to in mod function could you please explain this.except this i have understood all you programs. please reply to me .

  2. Identifying Prime numbers from 1 to 1000

    DECLARE @range int = 1000 –(Select your range from 2 to @range)
    ,@x INT = 1, @y int = 1

    While (@y <= @range)
    while (@x <= @y)
    IF ((@y%@x) =0)
    IF (@x = @y)
    PRINT @y
    IF ((@y%@x)0)
    set @x = @x+1
    set @x = 2
    set @y = @y+1
