Introduction

As a database administrator or developer, managing and maintaining a SQL Server database can be a daunting task. With the constant need to update, modify, and compare database schema, it's essential to have a reliable tool to help streamline the process. SQL Delta Snap is a snapshot tool designed to generate XML-based schema images of a SQL Server database. In this article, we'll delve into the world of SQL Delta Snap, exploring its features, benefits, and how to use it effectively.

What is SQL Delta Snap?

SQL Delta Snap is a snapshot tool that creates XML-based schema images of a SQL Server database. The resulting XML file layout is proprietary to SQL Delta, but it can be used with other tools as well. This tool is designed to work seamlessly with SQL Delta, allowing for database comparisons and other advanced features.

Key Features of SQL Delta Snap

Consistency with SQL Delta CLI

The recent release of SQL Delta Snap has made it more consistent with the SQL Delta command-line interface (CLI). This means that SQL Delta CLI projects can now work with Delta Snap, making it easier to manage and maintain your database schema.

Snapshot Saving

SQL Delta CLI now offers snapshot saving, which allows you to save multiple snapshot requests. This feature is particularly useful when working with large databases or when you need to compare multiple versions of your database schema.

Multiple Sets and Email Processing

Delta Snap now supports multiple sets, allowing you to process multiple snapshot requests simultaneously. Additionally, you can configure Delta Snap to send email notifications via SMTP upon completion of a snapshot request.

Mandatory and Optional Elements of a Snap Project

To create a Snap project, you'll need to define the mandatory and optional elements. The mandatory elements include:

Database Connection: Specify the connection details for your SQL Server database.
Schema: Choose the schema you want to snapshot.
Output File: Specify the location and name of the output XML file.

Optional elements include:
