What are some effective SQL package indexing techniques?

Effective SQL package indexing techniques include using clustered and non-clustered indexes, covering indexes, and filtered indexes.

Can you explain the difference between clustered and non-clustered indexes?

Sure! A clustered index determines the physical order of data in a table, while a non-clustered index is a separate structure that points to the data.

When should I use a covering index?

Use a covering index when you want to improve query performance by including all the columns needed for a query, reducing the need to access the table.

What are filtered indexes and when should I use them?

Filtered indexes are used to index a portion of the rows in a table based on a filter condition, which can improve performance and reduce index size.
