Maintaining an accurate and comprehensive inventory of your SQL Server environment is crucial for effective database management, ensuring security, and meeting compliance requirements. With PowerShell, database administrators can automate the collection of detailed information about SQL Server instances and databases, streamlining the inventory process. This blog post introduces a PowerShell script designed to efficiently gather SQL Server inventory data, separating instance-level information from database-specific details into two distinct reports.

Ensuring Optimal Execution Plans in SQL Server
Explore professional strategies for managing SQL Server Plan Regression. This guide offers insight into preventing performance degradation through efficient execution plan selection and maintenance, ensuring optimal query performance in SQL Server environments.
Migrating SQL Server On-Prem Workloads to Azure Virtual Machines
Migrating from an on-premises SQL Server to an Azure Virtual Machine (VM) encompasses not just a technological shift but also a strategic transformation that demands foresighted planning and preparation. This refined approach focuses on the preliminary steps necessary to ensure not just a seamless transition but also an optimized post-migration environment. Emphasizing benchmarking your current infrastructure and tailoring capacity planning to the specific types of workloads being migrated, this guide aims to lay a solid foundation for your move to Azure.
SQL Server Stress Testing: A Step-by-Step Guide Using ostress
Today we will explore a practical approach to enhancing the performance of your SQL Server instances using ostress. This tool, part of the RML Utilities for SQL Server, is a game-changer for database administrators and developers looking to simulate heavy workloads and ensure their databases can handle the pressures of real-world applications. This comprehensive guide will walk you through the essentials of downloading RML Utilities, setting up your test environment, and leveraging ostress for performance testing.
Understanding and Diagnosing SQL Server Wait Types
In SQL Server, wait types are important indicators of where and why delays occur during query execution, directly impacting database performance. Properly understanding and diagnosing these wait types enable database administrators to pinpoint specific performance bottlenecks. This blog post aims to provide an overview of essential wait types that demand attention, distinguish common wait types that can usually be ignored, and offer strategies for effective diagnosis and interpretation to enhance overall database performance.
Automating Data Insertion into SQL Server with PowerShell
PowerShell is a powerful scripting language that can automate a wide range of tasks, including database operations. In this post, we’ll demonstrate how to create a DataTable in PowerShell, populate it with random data, and then save that data into a table in SQL Server using SqlBulkCopy. We will first look at what is required for this task and then we’ll script it out.
Unraveling the Mystery of SQL Server Execution Plans
SQL Server execution plans are invaluable tools for diagnosing and optimizing database queries. They provide a visual representation of the operations SQL Server performs to execute a query. Understanding how to read these plans is essential for identifying performance bottlenecks and optimizing query performance. This post will guide you through understanding and reading execution plans, highlighting what to look for in poorly performing plans, and offering strategies to find and remove bad plans.
SQL Server’s Query Optimizer: Bridging the Gap to Peak Performance
We are always in search of ways to optimize query performance. At the heart of achieving these goals within SQL Server is the Query Optimizer, a sophisticated component of the SQL Server Database Engine. Its primary role is to evaluate various potential execution plans for a given query and select the most efficient path forward. This process is necessary for minimizing resource consumption and execution time, while enhancing the overall performance and scalability of database operations.
Automating SQL Server Database Refreshes with PowerShell
In today’s agile software development environment, keeping lower environments like development and testing synchronized with production data is essential. It not only helps in identifying issues early but also ensures that features are developed and tested against the most current dataset. This blog introduces a PowerShell script that automates the process of refreshing a SQL Server database in lower environments using a “copy only” backup from a production environment. By diving into the script, we aim to shed light on how automation can simplify database management tasks, making them more efficient and error-resistant.
Leveraging C# within PowerShell for Advanced ETL Operations in SQL Server
The ability to efficiently perform Extract, Transform, Load (ETL) operations is essential for database administrators and developers, particularly those working with data warehouses and others with large data transformation. While PowerShell is a powerful tool in its own right for database management, embedding C# within PowerShell scripts can significantly enhance your ETL processes. This blog post will guide you through a practical example of using C# code within a PowerShell script to perform ETL operations on SQL Server tables. We’ll start with extracting data from a SQL Server, followed by transforming it using C#, and finally, loading it back into a different table.
