Editorial - The Auditing Poll |
|||||||||||||||||
Our database systems become more important to the operation of our world all the time. We store data from sensors, back commerce systems, and more. We know software has bugs, and there will be security lapses, perhaps even from insiders. I suspect that as our software evolves, auditing will become more and more important all the time. This week I'm curious to what extent you have auditing in your environment. For some of us it's included in the software we write, for others we might have to retrofit auditing when some issue occurs, but most applications I've used have very limited auditing or logging capabilities. How extensively is auditing deployed in your environment.Whether it's something simple like a Trace or Extended Events, the built-in SQL Audit, or some third party product, what percentage of your applications use some sort of auditing or logging? Is it a requirement, perhaps for certain types of systems? Or is it rarely implemented? I think auditing will become more prevalent in the future, perhaps even a core function that we expect to find in every piece of new software. » Join the debate, and respond to today's editorial on the forums

Yesterday's Question of the Day |
|||||||||||||||||
|
I execute the following T-SQL DECLARE @A INT,@B INT, @C INT SET @A = 2 SET @B = 3 SET @C = 4 SELECT (@A + @B)-@C AS 'Result #1' SELECT @A + (@B-@C) AS 'Result #2' SELECT (@A + @B) * @C AS 'Result #3' SELECT @A + (@B * @C) AS 'Result #4' The question is what are the results returned by each of the 4 select statements. The results are shown as: Result #1, #2, #3, #4 For example, the results might be 1,20,3,41 (not the correct answer) Answer: 1,1,20,14 Explanation: You need to understand the precedence in mathematical operations. Parenthesis are handled before other operations. Multiplication and division come before addition and subtraction, which are handled left to right.
