The number values in the IN caluse is a variant.In the given example I given only 4.somethimes its more than 30 numbers.

SELECT        ID
FROM          TableName
WHERE        (ID IN (16, 18, 15, 20 ))

Result : 15 ,16,18,20 

Is there any way to retrieve values In the same order of values given in IN caluse.
Result should like this Result : 16,18,15,20

Answer 1

There is no way to tell the db engine to examine the order of values in the IN() list and apply that same order to the ORDER BY.

You could apply the same ordering by using a Switch() expression, but then you would have to keep Switch() and In() synchronized.

SELECT id
FROM YourTable
WHERE id In (16,18,15,20)
ORDER BY 
    Switch(
        id=16,1,
        id=18,2,
        id=15,3,
        id=20,4
    );
