Are SQL Server database triggers evil?

January 25, 2017 by

Introduction

There is a lot of talk about how bad triggers are, how you should never use them, etc. I wanted to spend some time reviewing fact vs fiction and do an objective analysis of SQL Server database triggers (both DDL and DML), warts and all. We will review alternatives and compare them with triggers to determine advantages vs disadvantages of each approach.

Using Memory-Optimized Tables to Replace SQL Server Temp Tables and Table Variables

January 24, 2017 by

TempDB usage can be considered as a performance bottleneck for workloads that use temp tables and table variables intensively resulted in heavy IO usage. A valuable alternatives for the temp table and table variable are SCHEMA_ONLY Memory-Optimized tables and the Memory-optimized Table Variable, where the data will be completely stored in the memory without the need to touch the TempDB database, providing the best data access performance. SCHEMA_ONLY Memory-Optimized table and the Memory-optimized Table Variable are stored only in the memory with no related component in the disk. It involves no IO activity or TempDB utilization. It can also participate in the transactions without the need to log the transactions.

Connecting PowerShell to SQL Server – Using a Different Account

January 24, 2017 by

Introduction

In a previous article on Connecting PowerShell to SQL Server I went over how you use various methods in PowerShell to connect to SQL Server. In those examples though I only touched on using the current user that is running “PowerShell.exe”. In this article I want to pick up and go over how you would use the same methods, but as a different account. I will cover using both Windows Authentication (where supported) and SQL Login authentication.

How to administer SQL Server Reporting Services (SSRS) subscriptions using PowerShell

January 23, 2017 by

In the article Report Subscription Changes in SQL Server Reporting Services 2016, I covered several changes to standard and data-driven subscriptions that were introduced in the release of SQL Server 2016. However all of those changes related to administering report subscriptions using a GUI (i.e. Report Manager Portal, SSRS Configuration Manager). The release of SQL Server Core, SQL Server on Linux and enhancements on Windows PowerShell, reinforces the growing shift by Microsoft to have SQL Server professionals adopt scripting as one of the ways to carry out their daily tasks. In this article we continue to explore SQL Server Reporting Services (SSRS) subscription feature by discussing some of the Windows PowerShell commands that can be utilised to administer report subscriptions.

Best Practices for Configuring Newly Installed SQL Server Instances

January 20, 2017 by

Often we install SQL Server on clients or we get to clients where they have pre-installed SQL Server Instances. As a DBA we have the Primary responsibility of keeping the Database Up and Running. This responsibility leads to optimizing, performance tuning and many other stuff related to database’s internal objects. While keeping the other aspects in mind many of us have to go through the configuration of the newly installed or pre-installed but un-configured instances. Configuring SQL Server newly instances are not an easy task and a DBA might want to configure an Instance in many ways.

SQL Server Job Performance – Reporting

January 19, 2017 by

Description

Once collected, job performance metrics can be used for a variety of reporting needs, from locating jobs that are not performing well to finding optimal release windows, scheduling maintenance, or trending over time. These techniques allow us to maintain insight into parts of SQL Server that are often not monitored enough and prevent job-related emergencies before they become emergencies.

Using sp_server_diagnostics

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.

Scaling out Reporting Services & changes in SQL Server 2016

January 18, 2017 by

Scaling out Reporting services to multiple nodes, in itself, is a relatively simple process. It’s when we come to solve problems and investigate performance that we begin to see there is a lot more going on under the hood that’s not clear through implementation. There are also some foundational elements that have changed in SQL 2016 with next to no guidance from Microsoft on the changes.

How to secure your passwords with PowerShell

January 18, 2017 by

Introduction

Do you have processes or scripts that require you to provide a password? Against the desires of your security officer, do you have to save those passwords in plain text, in your scripts? PowerShell offers a way that you can store a password or prompt the user for the information. You can then utilize that information to build what is known as a PSCredential. The majority of commands for PowerShell that support remote connections to servers (WMI, CIM, Invoke-Command, etc.), offer the ability to pass in a credential. While some only need the password, some need the full object to authenticate a user. This object in PowerShell can be made a few different ways based on your needs. I will go over a few options that are commonly used, but first lets discuss what makes up a PSCredential.

Deploying Packages to SQL Server Integration Services Catalog (SSISDB)

January 16, 2017 by

Starting with SQL Server 2012, Integration Services (SSIS) packages can now be deployed to a single source for managing execution in multiple environments. The SSIS Catalog is a single database container for all deployed packages. The configuration files are replaced with Environments. Deployed versions are tracked historically and a package can be reverted to a previous deployment. On top of these features, internal reports with a dashboard help when debugging errors or examining performance over time.

Understanding SQL Server database static data and how it fits into Database lifecycle management

January 13, 2017 by

What is static data

Static data (aka Code, Lookup, List or Reference data), in the context of a relational database management system, is generally data that represents fixed data, that generally doesn’t change, or if it does, changes infrequently, such as abbreviations for US states for example e.g. ME, MA, NC. This data is typically referenced, extensively, by transactional type data. For example, an customer table would have references to static table for City name, State or province, Country, Payment terms e.g. NET 30 etc.

SQL Server 2016 Always On Availability Group with Direct Seeding

January 12, 2017 by

SQL Server Always On Availability Groups are an enterprise-level high-availability and disaster-recovery feature introduced the first time in SQL Server 2012as an alternative to database mirroring. A set of user databases that fail over together forms the availability group. These availability databases are hosted by the availability replicas and can be readable- writable at the primary replica and up to eight sets of secondary replica databases that can be configured to be read-only databases. The availability groups fail over due to the availability replica’s level issues and not the ones caused due to database level issues such as data loss or database corruption.

Parameterizing Database Connection in SQL Server Integration Services

January 12, 2017 by

SQL Server Integration Services (SSIS) has been growing into an enterprise solution over the last three releases. Variables were a step in that direction, but with Project deployments to the SSIS Catalog in SQL Server 2012 Microsoft has stepped it up, even more. Project parameters have become the go to solution for changing variable values in packages at run time. This article is going to dive into an example that parameterizes the Server Name and Initial Catalog (database name) in a connection string for packages in a project.
