FAQ’s of Transact-SQL Programming Language
T-SQL is an extension of the Structured Query Language (SQL) specifically designed for use with Microsoft SQL Server and Sybase databases. While it shares the fundamentals of SQL for querying and modifying data, T-SQL includes additional features for procedural programming, error handling, and integration with the database engine.
Stored procedures in T-SQL are precompiled sets of SQL statements stored in the database. They provide advantages such as improved security, code reusability, and performance by allowing developers to encapsulate logic and execute it as a single unit. Stored procedures are essential for building robust database applications.
T-SQL provides transaction management capabilities through commands like BEGIN TRANSACTION, COMMIT, and ROLLBACK. Transactions ensure that a series of database operations either succeed as a whole or fail completely, maintaining data consistency and integrity. Proper transaction management is crucial to prevent data corruption and maintain data accuracy.
Triggers in T-SQL are special types of stored procedures that automatically execute in response to specific database events, such as data inserts, updates, or deletes. They are used to enforce data integrity rules, implement audit trails, and automate actions based on database events. Triggers should be used when you need to ensure certain actions always occur in response to specific data changes.
