What is a clustered index?
An example of an AI chatbot conversation about clustered indexes in databases.
What is a clustered index?
A clustered index is a type of index that sorts and stores the data rows in the table based on the values of one or more columns.
How does it differ from a non-clustered index?
Unlike a clustered index, a non-clustered index does not sort the actual data rows. Instead, it creates a separate structure that points to the data.
Can a table have multiple clustered indexes?
No, a table can only have one clustered index because the data rows can only be sorted in one order.
What are the benefits of using a clustered index?
Clustered indexes can improve the performance of queries that retrieve a range of values, as the data is stored in order.
