T-SQL vs. PL/SQL

T-SQL (Transact-SQL) and PL/SQL (Procedural Language/SQL) are both extensions of SQL, designed for specific database systems. T-SQL is used primarily with Microsoft SQL Server, adding features like procedural programming and error handling. PL/SQL, on the other hand, is associated with Oracle databases and supports similar enhancements, along with advanced capabilities for managing complex data operations. Essentially, both languages enhance standard SQL, but they're tailored for different database environments—T-SQL for SQL Server and PL/SQL for Oracle—each with its own unique features and functionalities.
