What is Transact-SQL Querying Training about?

Transact-SQL (T-SQL) is Microsoft’s proprietary extension of the Structured Query Language (SQL), used primarily with Microsoft SQL Server. It enhances standard SQL by adding procedural programming constructs such as variables, control-of-flow statements (e.g., IF, WHILE), error handling (TRY...CATCH), and built-in functions. T-SQL is used for writing queries, stored procedures, triggers, and functions to interact with and manipulate relational data in SQL Server databases. It plays a key role in data retrieval, data transformation, and database logic within enterprise-level applications.
