How to compare SQL databases in SSMS(SQL Server Management Studio)?

As part of a Big Data project, experts are often asked to find the best way to track changes applied to database tables, so that no requirement is created to load all the huge tables into the database. warehouse at the end of the day, if not all data was changed.

The first option available in SQL Server to track changes are the After Insert, After Update and After Delete triggers, which require coding efforts on your part to handle these changes or add data, in addition to the performance impact of the triggers on the system.

We effortlessly analyze and assess SQL changes with our intuitive tool. Compare SQL changes efficiently, ensuring seamless database management. Stay in control, identify modifications, and streamline your workflow with precision, simplifying the complexities of database evolution.

What is SQL Server?

SQL Server was developed by Microsoft as a relational database management system that has a long history, thirty-two years, to be exact. Microsoft SQL Server used to be considered a software product with the primary function of retrieving and collating data on demand from other software applications.

These applications can run on a different laptop over a community or on the identical laptop. Microsoft SQL Server has undergone many updates over time, becoming one of the best supported and maximum official RDBMS available on the market nowadays.

SQL Server owes tons of its recognition to its creator, Microsoft. When MS SQL Server became in its infancy, Microsoft had already set up itself as a technology giant.

SQL Server has managed to carve out a spot for itself as a database management gadget with its extensive variety of programs and equipment that simplify operating with records. Its entire graphical user interface permits you to work intuitively and without difficulty with the database, while permitting you to generate data to your reports.

What is a SQL database?

An SQL database happens to be a relational database, written in the query language structured SQL ( Server query language). A relational database is one that has a predefined relationship between its elements, where each record can be identified unequivocally. 

Advantages of SQL (Structured Query Language)

SQL databases have a series of advantages that have made them the most used type of database. The main advantages are:

It has tools that allow avoiding duplication of records, guaranteeing referential integrity (when a record is deleted, all related records dependent on it are deleted). 

They have greater support as they have been on the market for a long time.

Atomicity of information. While performing any operation on the database, if any problem arises, the operation is not performed. 

It has a well-defined standard system SQL for database operations, such as insertion, updating, or queries. This system is easy to understand since it adapts to a common language.

Configuration changes in SQL server cursors

When it comes to comparing code in different scenarios, you can make wrong conclusions. That is why it is so important to validate a statement before assuming it as an absolute truth. The same thing happens when you talk about configurations in TSQL cursors.

Configurations in cursors?

If you haven’t seen the options you have when using a cursor in SQL Server, it happens to be important that you know about them in the official cursor documentation.

These settings, seen as parameters in the cursor syntax, will determine the behavior of this object and, therefore, its performance.

Change Data Capture

Another tracking and capturing solution introduced in SQL Server 2008 Enterprise, which tracks any Insert, Update or Delete operations applied to user tables, with What, When and Where these changes were applied, without any extra coding effort and keeping it in the system tables so that they are easily accessible using normal queries.

When Change Data Capture happens to be enabled on a user table, a new system table will be created with the same structure as the source table, with extra columns to include the metadata changes.

SQL Server Change

Data Capture uses the SQL Server transaction log as the source of the changed data using an asynchronous capture mechanism. Any DML changes applied to the tracked table will be written to the transaction log. Process of Compare SQL changes reads these records and copies them to the capture table and finely adds the associated change information as change meta data to the same table.
