DBCC DBREINDEX / INDEXDEFRAG

Does SQL Server 2000 after executing DBCC DBREINDEX or
DBCC INDEXDEFRAG run the sp_updatestats?
Are the Logical Fragmentation statistics updated after
execute either the DBCC DBREINDEX or DBCC INDEXDEFRAG
procedures?
Thanks,

STATS_DATE returns the date that the statistics for the specified index
were last updated.

SQL Server doesn't "run" sp_updatestats. Create statistics is an inherent ef
fect of creating an index, which
in the end is what DBCC DBREINDEX does. INDEXDEFRAG does not update the stat
istics information, though.

There's no such thing as "Logical Fragmentation *statistics*". The reason yo
u defragment an index is to reduce
fragmentation. Logical Scan fragmentation is one type of fragmentation. So,
yes, this value will be reduced.
