Is T-SQL Stored Procedure Execution 'atomic'?

Question

Let\'s say I have a simple stored procedure that looks like this (note: this is just an example, not a practical procedure):

CREATE PROCEDURE incrementCounte         


        

Answer 1

I use this method

CREATE PROCEDURE incrementCounter
AS

DECLARE @current int

UPDATE MyTable
SET
  @current = CounterColumn = CounterColumn + 1

Return @current

this procedure do all two command at one time and it is isolate from other transaction.
