Transact-SQL

Transact-SQL (T-SQL) is a proprietary extension of SQL (Structured Query Language) developed by Microsoft and Sybase, primarily used for interacting with Microsoft SQL Server and Azure SQL Database. It adds procedural programming features such as variables, control-of-flow statements, error handling, and stored procedures to standard SQL, enabling complex data manipulation and business logic implementation directly within the database. T-SQL is essential for database administration, querying, and developing applications that rely on SQL Server.

Also known as: T-SQL, TSQL, Transact SQL, Microsoft SQL, SQL Server Language

🧊Why learn Transact-SQL?

Developers should learn T-SQL when working with Microsoft SQL Server or Azure SQL Database, as it is the primary language for writing queries, stored procedures, triggers, and functions in these systems. It is crucial for tasks like data analysis, reporting, and building scalable backend applications that require efficient database operations, especially in enterprise environments where SQL Server is widely deployed. Mastery of T-SQL allows for optimized performance and integration with other Microsoft technologies like .NET.

ABAP (Advanced Business Application Programming) is a high-level programming language created by SAP for developing business applications within the SAP ecosystem. It is primarily used for customizing and extending SAP ERP (Enterprise Resource Planning) systems, enabling developers to build reports, interfaces, forms, and workflows. ABAP runs on the SAP NetWeaver Application Server and integrates tightly with SAP's database and business logic layers.

ActionScript is an object-oriented programming language originally developed by Macromedia (later acquired by Adobe) for creating interactive content, animations, and applications primarily for the Adobe Flash platform. It is based on ECMAScript, sharing syntax similarities with JavaScript, and was widely used for web-based games, multimedia presentations, and rich internet applications (RIAs). While its usage has declined with the deprecation of Flash, it remains relevant for maintaining legacy Flash content and in niche areas like Adobe AIR for desktop and mobile apps.

Ada is a statically typed, high-level programming language designed for safety-critical and real-time systems, originally developed for the U.S. Department of Defense. It emphasizes reliability, maintainability, and efficiency, with strong support for concurrent programming and formal verification. The language is widely used in aerospace, defense, transportation, and medical devices where failure can have severe consequences.

Agda is a dependently typed functional programming language and proof assistant used for formal verification and theorem proving. It allows developers to write programs with precise types that can encode mathematical properties, enabling the construction of proofs about program correctness. It is based on intuitionistic type theory and is often used in academic and research settings for verifying software and mathematical theorems.

Alloy is a declarative modeling language and analyzer for software design, based on first-order logic and relational algebra. It is used to create lightweight models of systems to explore their behavior and verify properties through automated analysis. The Alloy Analyzer tool generates instances or counterexamples to help developers find design flaws early in the development process.

AMPscript is a proprietary scripting language developed by Salesforce for creating dynamic, personalized content in Marketing Cloud (formerly ExactTarget). It is primarily used within email marketing campaigns, landing pages, and SMS messages to insert data-driven content, perform conditional logic, and manipulate data from Salesforce CRM or other data extensions. The language is server-side processed and embedded directly within HTML content to generate personalized output at send time.
