A Fine Slice Of SQL Server
In this video, I show how to restore SQL Server databases using SQL Server Management Studio, T-SQL, and the dbatools PowerShell module.
Originally, I had plans on covering SSMS + T-SQL in one video, and then dbatools in a second. Then I decided, well, why not just cover both of them in the same video? And this is how we get to half-hour long videos.

Comments closedVenkata Gummadi works on vector search response times:
As data engineers, we are tasked with implementing these sophisticated solutions, ensuring organizations can derive actionable insights from vast datasets. This article explores the intricacies of vector search using Elasticsearch, focusing on effective techniques and best practices to optimize performance. By examining case studies on image retrieval for personalized marketing and text analysis for customer sentiment clustering, we demonstrate how optimizing vector search can lead to improved customer interactions and significant business growth.
Read on for a vector search primer and some guidance of how you can improve the performance of vector search queries. I’d expect that much of this can also apply to Azure AI Search and Amazon OpenSearch.
Comments closedPatrick Keisler helps a customer:
One of my customers recently wanted to rename each of the SQL audit files will the datetime stamp of when it was created. I explained to them the filename already contains a datetime stamp. While it does not look like a typical timestamp, it is based on the Windows Filetime data structure that is a 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 (UTC). Nonetheless, they still wanted a traditional datetime stamp in the file name.
Read on to see how. I can understand the displeasure in adding redundancy to a filename, though I also understand the reasoning from the customer’s point of view: FileTime isn’t human-readable in any meaningful way.
Comments closedGilbert Quevauvilliers performs an exfiltration:
With the new Schema’s in a Lakehouse, it now is possible to read from Lakehouse A (In Workspace A) and write to Lakehouse B (In Workspace B).
Here are more details about the Schema preview: Lakehouse schemas (Preview) – Microsoft Fabric | Microsoft Learn
This opens a whole new world of possibilities.
I also really like the fact that I can simply use the Names, and I do not need to get the actual GUIDS!
For example, I can use the following as shown below which is WorkspaceName.LakehouseName,SchemaName.TableName

Comments closedPatrick Gruenauer makes a funny noise:
It often happens that you have many, many parameters in PowerShell. The command then extends over several lines. That doesn’t look pretty. In this article, I will show you how to summarize these parameters and then use them in the command. Let’s get started.
