Setting a clustered index on a column (often the primary key) in a table in
SQL Server physically rearranges the order of the rows in the table. The
original comment was about whether data could be rearranged in a table
itself, to which I responded that a clustered index did this.

(and it's either "indices" or "indexes" :P )
