Learn the difference between clustered and non-clustered indexes in SQL to improve query performance
Action Steps
- Create a sample database using SQL to practice indexing
- Build a clustered index on a primary key column using the CREATE CLUSTERED INDEX statement
- Create a non-clustered index on a frequently queried column using the CREATE NONCLUSTERED INDEX statement
- Compare the query performance with and without indexes using the EXPLAIN and EXECUTE statements
- Apply indexing strategies to real-world database scenarios to optimize query performance
