What would be the better index Index1, or Index2?

MSDN[^] wrote:

Redesign nonclustered indexes with a large index key size so that only columns used for searching and lookups are key columns. Make all other columns that cover the query into nonkey columns. In this way, you will have all columns needed to cover the query, but the index key itself is small and efficient.

The preferred way to build indexes on large tables is to start with the clustered index and then build any nonclustered indexes

Mm.. you seem to recommend Index2 so I am confused by your "Index3" on the first line...

Super Lloyd wrote:

basically this is a table that aggregate a summary from multiple data sources. id0 and id1 identify the datasource and are small number (between 1 to 9 each) and id2 is the original record id in the foreign datasource.

Thanks for your feedback and MSDN quotes though!

create index index2 on Table (id0, id1, id2 DESC)

• Index 1 sorts the addresses by house number, and includes the first and last name. You have to start at the end and scan backwards until you find an entry for "John Smith".
• Index 2 sorts the addresses by first name, then last name, then house number. You can jump straight to the end of the "John Smith" records, and see the highest house number.
