What is the difference between clustered and non-clustered indexing?
An example of an AI chatbot conversation about indexing types in databases.
Can you explain the difference between clustered and non-clustered indexing?
Sure! Clustered indexing determines the physical order of data in a table, while non-clustered indexing creates a separate structure to point to the data.
So, does that mean a table can have only one clustered index?
Exactly! A table can only have one clustered index because it defines the order of the data. However, it can have multiple non-clustered indexes.
What are some advantages of using non-clustered indexes?
Non-clustered indexes can improve query performance by allowing faster lookups and can be created on columns that are frequently searched.
Are there any downsides to using indexes?
Yes, while indexes speed up read operations, they can slow down write operations because the index needs to be updated whenever data is modified.
