SQL Server Execution Times:

CPU time = 0 ms, elapsed time = 7 ms.

SQL Server parse and compile time:

CPU time = 0 ms, elapsed time = 0 ms.

SQL Server Execution Times:

CPU time = 0 ms, elapsed time = 0 ms.

It seems like function with CURSOR gives good peformance. I am confused...though we used CURSOR inside the function , it is taking less CPU time... But i just rewrite the code without using CURSOR ,i t is taking more CPU time. I am wondering how it is happening?
