Report Subscription Changes in SQL Server Reporting Services 2016

December 30, 2016 by

What makes SQL Server 2016 one of my favourite SQL Server release since the release of SQL Server 2012 is the increased number of exciting new features that have been introduced. Whilst my article Top 5 New SQL Server 2016 DMVs for DBAs reviewed some of these new features albeit from a DBA point of view, in this article I continue to review SQL Server 2016 but from the perspective of an SSRS administrator in relation to the changes in report subscriptions.

SQL Server Index vs Statistics a consultants woes…or rants

December 29, 2016 by

As a DBA, I am often asked why is something performing slow, what and why statistics need to be updated or what will cause them to be “off”. My initial question to clients when they pose these questions to me is what changed on your end? Did the data change significantly and did the rebuild or reorganize index job run? Before I get into the answers to these questions from my clients, let me give you some background. So, just to clarify, for most of my clients, I work as a remote part-time DBA, that being said, I manage their database from every aspect including setting up servers, backups/restored, troubleshooting, managing their index’s, etc. and again remotely. So normally, I have setup a jobs that will manage their index’s ranging from a weekly rebuild or even sometimes I use one that I’ve designed that makes a choice to either rebuild or reorganize an index based on fragmentation level. The “general rule of thumb” is reorganize the index for fragmentation from 5% to 29% and rebuild when 30% plus. Those are pretty standard numbers I did not make them up.

Introduction of Visual Studio Code for DBAs

December 29, 2016 by

Introduction

Visual Studio Code (Code), have you heard of this product yet? This is an open-source, cross-platform and extremely light weight code editor from Microsoft. You may see some folks explain this editor as the little brother to Visual Studio Community Edition (VS Community), but it is more compared to editors like Atom, Sublime Text or even Notepad++. It is not something you can use to compile program code, so it is for the less complex coding projects. I utilize Code as my editor of choice now with PowerShell, and even T-SQL at times. In this article, I wanted to walk you through using Code and note some specific extensions I use for PowerShell and SQL Server.

SQL Server Estimated Vs Actual Execution Plans

December 29, 2016 by

A SQL Server execution plan is the most efficient and least cost road map that is generated by the Query Optimizer’s algorithms calculations to execute the submitted T-SQL query. Execution plans are used by the database administrators to troubleshoot the performance of poorly performing queries to isolate the part of the query that is at the root of the performance issue.

How to Split a Comma Separated Value (CSV) file into SQL Server Columns

December 29, 2016 by

Receiving a comma delimited file is not new technology nor is it difficult to deal with in SQL Server. As a matter of fact, it is extremely easy. There are many cases as to why you would want to do this. For example, you have an external data source that needs to be imported into your database/table. There a couple ways to do this, however the quickest and easiest way is to use the native “import” feature within SQL Server Management Studio and you can even save it to an SSIS Package at the end of the process. The end result of using this method is that the external CSV file is loaded into a SQL Server table where columns are created and rows are populated.

Big Bonus Anyone?

December 19, 2016 by

Introduction

Late in October, I received an unusual request from the head of sales within one of my client sites. Sales sells three articles: bread, perfume and Jaguar motor cars. Now the reader will note that one of these items is a staple and the other two are for those folks with considerable disposable income. Management within the firm had increased the salesmen’s bonuses for those folks that managed to sell perfume and / or Jaguars along with the standard loaves of bread. The summary report may be seen below showing the final bonus rate for each sales order booked during the month.
