Question

I can’t for the life of me remember what the SQL (SQL Server 2005+) is to compact indexes after deletion i.e.

PK Identity  col1 col2
1            abc  def
3            abc  def

id 2 has been deleted – whats the command to essentially compact the indexes while keeping referential integrity (there’s a one line statement)

Thanks, (and I know I’m going to ‘face-palm’ when I see the answer)

Answer 1

The term in SQL is Reorganizing and Rebuilding Indexes and the commands for each of these are:

ALTER INDEX REORGANIZE

and

ALTER INDEX REBUILD 

But as per the opening line on that link “The SQL Server 2005 Database Engine automatically maintains indexes whenever insert, update, or delete operations are made to the underlying data.” so just leave it to the server.
