Question 1 of 28

In SQL, how do you explain the differences between clustered and non-clustered indexes? Can you name a time that you used each?

"In the simplest of terms, a clustered index order records in a table the way that they are physically stored. There can only be one clustered index per table. Non-clustered indexes do not store data to match the physical order that it is stored. Rather, it can hold up to 249 indexes per table. Both types come with their own benefits over the other. In my experience, clustered indexes are suited best for programs that use primary key as an identity integer column. On the other hand, non-clustered make the most sense for programs that need JOIN and WHERE clauses within them."
