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.

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.
Automating SQL Server Index Maintenance with PowerShell
In this blog post, we’ll focus on automating index maintenance using PowerShell. We’ll present a complete script to assess index fragmentation and perform necessary maintenance tasks, followed by a detailed explanation of each part of the script, showcasing how PowerShell can be a powerful tool in the arsenal of any SQL Server administrator.
Exploring Programming Constructs in T-SQL – Part 1: Variables and Conditional IF Statements
Welcome to the first installment in our blog series on understanding and using programming constructs in T-SQL (Transact-SQL). This series aims to unravel the intricacies of T-SQL, Microsoft SQL Server’s powerful extension to SQL (Structured Query Language). Our journey will cover the most common and impactful programming constructs, equipping you with the knowledge to write more efficient, dynamic, and robust SQL scripts.
Mastering SQL Server Extended Events for Proactive Database Troubleshooting
SQL Server Extended Events (XE) are an essential tool for modern database professionals, offering a lightweight, efficient solution for monitoring and diagnosing SQL Server. Outperforming older methods like SQL Trace, Extended Events provide a detailed view of database operations with minimal impact on performance. They are integral for identifying, analyzing, and resolving complex database performance issues and are built directly into the SQL Server engine for maximum scalability and precision.
Balancing Workloads in SQL Server with Resource Governor
Today’s database landscape requires strategies for ensuring optimal performance and resource allocation for your workloads. SQL Server’s Resource Governor is a feature that often flies under the radar but can be essential for fine-tuning the performance of your SQL Server environment. This blog post aims to demystify the Resource Governor, explaining its functionality, utility, and walking you through a practical example of setting it up for different user groups.
Implementing Row-Level Security in SQL Server
Row-level security (RLS) in SQL Server is a feature that allows database administrators to control access to rows in a database table based on the characteristics of the users accessing them. This can be particularly important in environments where data privacy and security are critical. In this blog post, we’ll explore how to implement RLS in SQL Server.
Contained Databases in SQL Server: Improving Database Portability and Security
Contained databases in SQL Server signify a paradigm shift in the world of database management, marking a move towards more self-contained and autonomous database systems. This approach redefines the traditional relationship between databases and the SQL Server instances they reside in, bringing a multitude of benefits in terms of management, portability, and isolation.
Optimizing SQL Server 2022: Leveraging Auto-Drop Statistics
Auto-Create statistics is a well-known feature critical for the database performance. When one statistic is auto created, changing the table structure is not blocked by the presence of the statistic. An auto-created statistics is also dropped automatically when a schema change happens. On the other hand, if the statistic is created by the user, any schema change will be blocked by the presence of the statistic. The Auto-Drop setting on a statistic is a new SQL Server 2022 feature to change this behavior.
