8. CREATE [ UNIQUE ] [ CLUSTERED | NONCLUSTERED ] INDEX index_name
ON <object> (column [ ASC | DESC ] [ ,...n ] )
[ INCLUDE (column_name [ ,...n ] ) ]
[ WHERE <filter_predicate> ]
[ WITH ( <relational_index_option> [ ,...n ] ) ]
[ ON { partition_scheme_name (column_name)
| filegroup_name
| default
}
]
[ FILESTREAM_ON { filestream_filegroup_name | partition_scheme_name | "NULL" } ]
[ ; ]

9. ALTER INDEX { index_name | ALL }
ON <object>
{ REBUILD
[ PARTITION = ALL ]
[ WITH ( <rebuild_index_option> [ ,...n ] ) ]
| [ PARTITION = partition_number
[ WITH ( <single_partition_rebuild_index_option> ) [ ,...n ] ]
]
| DISABLE
| REORGANIZE
[ PARTITION = partition_number ]
[ WITH ( LOB_COMPACTION = { ON | OFF } ) ]
| SET ( <set_index_option> [ ,...n ] )
}[ ; ]

10. DROP INDEX
{ <drop_relational_or_xml_or_spatial_index> [ ,...n ]
| <drop_backward_compatible_index> [ ,...n ]
}
