Importing PDF Contents into SQL Server

Published 2024-12-04 by Kevin Feasel

Sebastiao Pereira loads a PDF:

PDF forms are widely used for data collection, document processing, and digital workflows due to their versatility and consistency across different platforms and devices. They are essential in various industries, including healthcare, education, finance, government, and business. How do you retrieve data from PDF forms and insert into a SQL Server database table?

Read on for an answer using Visual Basic, which is a name I haven’t heard in quite some time.

Updates on the Spark Connect Dotnet Library

Published 2024-11-18 by Kevin Feasel

Ed Elliott has an update for us:

There have been quite a few changes in the last couple of months and I just wanted to give a quick update on the current state of the project. In terms of usage I am starting to hear from people using the library and submitting pr’s and requests so although usage is pretty low (which is expected from the fact that the Microsoft supported version usage wasn’t very high) it is growing which is interesting.

Read on for thoughts on production readiness, support for Spark 4.0, a couple of other updates, and some future plans.

Showing SSRS Reports in Modern .NET Apps

Published 2024-11-05 by Kevin Feasel

Sebastiao Pereira solves a problem:

Report Viewer was originally developed for the .NET Framework. As the industry shifts towards .NET Core, developers who have traditionally relied on this tool have faced challenges displaying reports within their applications due to compatibility issues. Is it possible to display a report from SQL Server Reporting Services (SSRS) in a .Net Core Application?

Click through for the answer. As a quick note, we had .NET Core, but then Microsoft renamed it to .NET with .NET 6, so instead we have to differentiate .NET Framework (Windows-only, heavy SDK) with .NET (nee .NET Core, cross-platform, less heavy). I’d rate Sebastiao’s solution a workaround, but one that I doubt Microsoft will ever provide a better solution for, given the heavy de-emphasis on Reporting Services over the past several years.

Updates in .NET 9

Published 2024-10-31 by Kevin Feasel

Ajay Jajoo tells us what’s new:

One of the standout features of .NET 9 is its focus on performance. With numerous optimizations across the runtime and libraries, applications can expect faster execution times and reduced memory usage. This is particularly beneficial for high-load applications, making .NET 9 an ideal choice for cloud-based solutions.

.NET 9 brings various performance optimizations, including improvements in garbage collection and just-in-time (JIT) compilation.

If you work at all with C#, you’ll see some quality of life improvements in .NET 9. But given Microsoft’s policy around short-term and long-term releases, you might wait until .NET 10 in many corporate environments to see them.

System.Data.SqlClient Deprecated

Published 2024-08-26 by Kevin Feasel

David Engel has an announcement:

We announced Microsoft.Data.SqlClient in the first half of 2019 and shipped the first stable package later that year. That release coincided with .NET Core 3.0. We’ve been developing Microsoft.Data.SqlClient in the dotnet/SqlClient repo since that time, over the last five years. It’s now time to start the deprecation process for the System.Data.SqlClient package. We plan to take a staged process to deprecation, with the intent to align support changes and associated code transition activities between these libraries to natural migration points between .NET major versions.

I haven’t used System.Data.SqlClient in a while, so I’m not sure how much is in that library that isn’t in Microsoft.Data.SqlClient.

Script Tasks in Azure DevOps Pipelines

Published 2024-07-17 by Kevin Feasel

Justin Bird builds a script task:

There are several dedicated script tasks that can be used for different purposes, some of the tasks have shortcut tasks which require much less input and are arguably easier to read. In the examples below, I have included the required inputs needed to run the scripts but in most cases, other optional inputs are available.

This looks pretty similar to the way you’d do it in GitHub Actions workflows as well—no surprise there, considering that the same group of people who built pipelines in ADO handled Actions in GitHub.

Building a Full-Stack App with Kafka and Node.js

Published 2024-07-12 by Kevin Feasel

Lucia Cerchie builds an application:

A well-known debate: tabs or spaces? Sure, we could set up a Google Form to collect this data, but where’s the fun in that? Let’s settle the debate, Kafka-style. We’ll use the new confluent-kafka-javascript client (not in general availability yet) to build an app that produces the current state of the vote counts to a Kafka topic and consumes from that same topic to surface them to a JavaScript frontend. 

Why are we using this client in particular? It comes from Confluent and is intended for use with Apache Kafka® and Confluent Platform. It’s compatible with Confluent’s cloud offering as well. It builds on concepts from the two most popular Kafka JavaScript client libraries: KafkaJS and node-rdkafka. The functionality is based on node-rdkafka, however, it also provides a way to interface with the library via methods similar to those in KafkaJS due to their developer-friendy nature. There are two APIs: the first implements the functionality based on node-rdkafka; the second is a promisified API with the methods akin to those in KafkaJS. By choosing this client, we can access wide functionality and have a smooth developer experience via the dev-friendly methods.

Click through for the code and explanation. Meanwhile, tabs in my heart, spaces in my job.

Building a Data API (with POST Operations) using Data API Builder

Published 2024-07-09 by Kevin Feasel

Eduardo Pivaral digs into DAB:

In the previous tip on Data API Builder (DAB) for SQL Server, we discussed how REST APIs provide a secure and platform-agnostic method to share database information using REST or GRAPHQL and how DAB simplifies the process of creating data APIs without the need for extensive coding or third-party tools.

What can we do if we want POST operations? Is it possible to achieve? What other options do we have if we want to implement Data API solutions in our production environments?

Read on to learn more about how this works.
