Can you explain the different types of partitioning?

Sure! The main types of partitioning are range partitioning, list partitioning, hash partitioning, and composite partitioning. Each type has its own use cases depending on how you want to organize your data.

How do I implement partitioning in my SQL database?

To implement partitioning, you typically use the CREATE TABLE statement with the PARTITION BY clause. The exact syntax can vary depending on the SQL database system you're using, like MySQL, PostgreSQL, or SQL Server.
