This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The RebuildIndex method re-creates an index implementing a Microsoft SQL Server PRIMARY KEY or UNIQUE key constraint.
Use the RebuildIndex method when the Type property of the Key object returns SQLDMOKey_Primary or SQLDMOKey_Unique, and the object references an existing table key.
Set the FillFactor property of the Key object prior to calling the method to alter key-maintaining index density. For more information about index fill factor, see CREATE INDEX.
