First of all your question is wrong as like as Sandeep said.

Alternatives to using a cursor:
- Use WHILE LOOPS
- Use temp tables
- Use derived tables
- Use correlated sub-queries
- Use the CASE statement
- Perform multiple queries

But Here I gave you the links for

Solution 1

You need to read on dude!

If you would have know what are 1, 2 & 3.. it would be hardly take 2 seconds to reply back. Further, you should have atleast Googled on what 1, 2 & 3 are.

2 & 3 are no where what a cursor does. Temporary tables work can be replaced by cursors at time.
