What are some examples of partitioning in SQL?

Partitioning in SQL involves dividing a database into smaller, more manageable pieces. For example, you can partition a sales table by year, so each year's data is stored separately.

Can you explain how range partitioning works?

Sure! Range partitioning divides data based on a specified range of values. For instance, you could partition a table by date, where each partition contains data for a specific month.

What about list partitioning? How does that differ?

List partitioning allows you to define specific values for each partition. For example, you could create partitions for different regions, where each partition contains data for a specific region like 'North', 'South', etc.

Are there any performance benefits to using partitioning?

Yes, partitioning can improve query performance by allowing the database to scan only relevant partitions instead of the entire table, which speeds up data retrieval.
