Explain the difference between subquery,CTE and stored procedures
Understanding the differences between stored procedures, subqueries, and Common Table Expressions (CTEs) is essential for anyone working with databases. Stored procedures are precompiled collections of SQL statements that can be executed as needed, often used for complex logic. Subqueries allow for querying within another query, while CTEs provide a way to define temporary result sets that can be referenced within a SELECT, INSERT, UPDATE, or DELETE statement. Knowing when and how to use these tools can significantly enhance database performance and efficiency.
