March 31, 2017 by

As a Microsoft SQL Server Database Consultant, I have to visit multiple companies with variety of SQL Server versions and patch level. Generally speaking, we need to analyze the environment of these clients and get information about the infrastructure. To do so, we have to run multiple scripts and tools on almost all the machines at client. Though it’s a part of our job but at times it takes hours to get even the basic information about the SQL Server versions, patch level, configuration and small details which even client does not have.

Standalone Managed Service Accounts, introduced a long ago with Windows Server 2008 R2, were a ray of hope for the database administrators. They promised to provide automatic password management and simplified SPN management, meaning that the time-consuming task of maintaining passwords would be a thing of the past (not to mention the required downtime for this).

January 19, 2017 by

Troubleshooting SQL Server is all about gathering the right evidence. Ordinarily we utilise a variety of different methods and analyse their output to look for specific areas where we would focus our diagnostic efforts. We could for example, use the results of various DMVs to look at wait statistic and resource information to help us focus our investigation in a particular area of SQL Server.

Optimize NULL values storage consumption using SQL Server Sparse Columns

August 29, 2016 by

SQL Server 2008 introduces a new column attribute that is used to reduce the storage consumed by NULL values in the database tables. This feature is known as Sparse Columns. Sparse Columns work effectively in the case of the columns with high proportion of NULL values, as SQL Server will not consume any space storing the NULL values at all, which helps in optimizing the SQL storage usage.

How to copy tables from one database to another in SQL Server

April 29, 2016 by

In some cases, as a DBA, you are requested to copy the schema and the content of specific tables from a database to another one in the same instance or in a different SQL instance, such as copying specific tables from a production database to a DEV one for testing or troubleshooting purposes.

SQL Server offers a lot of methods that can be used to perform table’s data and schema copy process. In order to go through each one of these methods, we will consider the below scenario:

  • The hosting SQL Server: localhost.
  • Both databases hosted in the same SQL Server 2017 instance
  • The source database: AdventureWorks2018
  • The destination database: SQLShackDemo

Perform volume maintenance tasks security policy

April 4, 2016 by

Introduction

You may see it more commonly referenced as Database Instance File Initialization (DIFI). If you are not familiar with the file initialization, this is the process SQL Server has to go through when it is creating the data files for a given database, and also during an expansion event (either manually or from auto growth) for a database. It only pertains to the data file(s) of the database, as log files are not affected by this security policy. SQL Server will “zero out” the file, basically fill it up with a bunch of zeros to allocate the amount of space requested. If you are a new DBA, this configuration actually goes all the way back to SQL Server 2005.
