The indexes are rebuilt too. On disk also.

| The indexes exist, just like the table still exists, but the indexes don't refer to any data since there is no data to refer to. Add data to the table and the indexes will act like they are supposed to.=================================================There are two kinds of light -- the glow that illuminates, and the glare that obscures. -James Thurber |

So they dont refer to addresess that contained the data before being truncated...or do they point to the addresses?? |

| If your concern is whether there will be orphaned data/rows in the indexes, you do not need to worry about that. When you insert, delete, or update a row from a table (or when you truncate the table) SQL Server updates the indexes automatically as part of the operation in a single transaction. So the table and the indexes will always be in sync. |
