[Note from Pinal]: This is a 77th episode of Notes from the Field series. Every week, I personally wait for the notes from the fields from Mike because it contains lessons of life which directly impacts DBA and Developer’s life positively. Mike Walsh is an amazing person to meet and know. I am fortunate to be his friend. Every single time I meet him, I learn something as a human. He is always looking for an opportunity to improve the life of DBAs and Developers.
Recently, when I was at a conference, one of the attendees came to me to ask a question. The conversation was as below for cross-database transactions.
The best way to learn something is to revisit some of the older blogs and then look at finding a more efficient way to work on the same problem. Recently I was looking at the forums to find a question come up again and again around making a comma separated list. This is not new over this blog and if you search you will get few. Long time ago I have written below blogs to show the values stored in table as comma separate list – this is not a rehash of what was written before but a newer way to solve the problem again.
I always get an opportunity to talk on topics that are basic from time to time. As I was preparing for GIDS 2015 (Great Indian Developer Summit) this year, I was vividly remembering one of the conversations I had with an attendee last year at our Pluralsight booth. Most of these conversations are forgotten, but this one was unique. During this conversation, the attendee was trying to learn the basics and was curious to listen to me. I always get carried away and spend quite some time with folks who are eager to learn. In this context, I was talking how RDBMS’s use the concept of Write-Ahead Transaction Log for maintaining ACID properties. The response I got was interesting – “Hey Pinal, is there a way to know which of the pages in memory are currently dirty? Do you know how to get this?”
How many times you had a problem where you have deployed a high availability solution, but the application is not able to use database and getting login failed for user after failover? Note that this issue would happen only with SQL Logins not Windows Login. You would understand the reason shortly. Here are the situations where you might face login failure.
