Transact-SQL (T-SQL) is a programming language used to manage and manipulate relational databases.
It is a proprietary language developed by Microsoft and is the primary language used for programming Microsoft SQL Server.
T-SQL is an extension of the SQL (Structured Query Language) standard and adds additional functionality and control over data and database objects.
It supports a wide range of operations including data definition, data manipulation, data control, and data query.
T-SQL also supports programming constructs such as variables, loops, and conditional statements, making it a powerful tool for database programming and management.
Additionally, T-SQL has built-in functions for performing tasks such as string manipulation, mathematical operations, and date and time calculations.
T-SQL allows the creation of stored procedures and functions, which can improve code reusability, enhance security, and provide better performance.
Stored procedures can be precompiled, leading to faster execution, and they can be called from various applications.
T-SQL supports explicit transaction control using keywords like BEGIN TRANSACTION, COMMIT, and ROLLBACK.
This helps ensure data integrity by allowing developers to define and manage transaction boundaries explicitly.
T-SQL provides robust error-handling mechanisms, allowing developers to catch and handle errors gracefully.
TRY...CATCH blocks can be used to encapsulate code where errors may occur, making it easier to identify and address issues.
T-SQL supports both DML and DDL operations, allowing developers to not only query and manipulate data but also define and modify the structure of the database.
This comprehensive support streamlines the development and maintenance of database applications.
T-SQL provides a range of security features, including the ability to define user roles, grant permissions, and implement encryption.
This ensures that data is accessed and modified only by authorized users, contributing to a secure database environment.
Overall T-SQL is a powerful and versatile language that is widely used in enterprise environments for managing and manipulating relational databases.
SQL (Structured Query Language) is a non-procedural language for querying and modifying data in the database.
SQL allow you to define, select, modify data, and also allow the control access to them. SQL commands can be embedded in programs written in other languages as C/C++, Java, PHP, Python.
SQL encompassed several components, of which the most important are: DDL - Data Description Language and DML Data Manipulation Language.

SQL Server is a relational database management system (RDBMS) developed by Microsoft.
It is commonly used to store and manage large amounts of data, and is often used in enterprise environments.
SQL Server is highly customizable and can be used to create a wide variety of applications, from simple data storage to complex enterprise systems.
It provides a number of features that make it easy to manage and query large amounts of data, including indexing, full-text search, and support for complex queries.
Additionally, SQL Server provides robust security features, including built-in encryption and support for role-based access control, to help ensure that data is protected from unauthorized access.
Microsoft SQL Server uses query language SQL and T-SQL is his extension. The fastest way to learn SQL Sever is to start reading the examples of SQL Sever page.
