Structure of a Multi-column index in SQL server
Where can I find a good representation of the of how data is stored in pages and how the B tree is constructed for a multi-column index (specifically for SQL server, but not necessarily)?
I'm referring to something like what you see in https://learn.microsoft.com/en-us/sql/relational-databases/reading-pages?view=sql-server-ver15 (for single column) but extended for multi-columns.
Another example for single column index:
Thanks.
I found this example very informative, hope you are looking for something like this. It shows include columns as well (SQL-Server specific). If you don't need include-columns, simply take everything without 'age' and 'sex' in the leaf node. There is a good explanation in the original article (which I hope you might not need).
