[!INCLUDE[appliesto-ss-asdb-xxxx-xxx-md](../../includes/appliesto-ss-asdb-xxxx-xxx-md.md)]

This topic describes how to modify the properties of an index in [!INCLUDE[ssCurrent](../../includes/sscurrent-md.md)] by using [!INCLUDE[ssManStudioFull](../../includes/ssmanstudiofull-md.md)] or [!INCLUDE[tsql](../../includes/tsql-md.md)].

### <a name="Restrictions"></a> Limitations and Restrictions

- The following options are immediately applied to the index by using the SET clause in the ALTER INDEX statement: ALLOW_PAGE_LOCKS, ALLOW_ROW_LOCKS, OPTIMIZE_FOR_SEQUENTIAL_KEY, IGNORE_DUP_KEY, and STATISTICS_NORECOMPUTE.
- The following options can be set when you rebuild an index by using either ALTER INDEX REBUILD or CREATE INDEX WITH DROP_EXISTING: PAD_INDEX, FILLFACTOR, SORT_IN_TEMPDB, IGNORE_DUP_KEY, STATISTICS_NORECOMPUTE, ONLINE, ALLOW_ROW_LOCKS, ALLOW_PAGE_LOCKS, MAXDOP, and DROP_EXISTING (CREATE INDEX only).

## <a name="TsqlProcedure"></a> Using Transact-SQL

### To see the properties of all the indexes in a table

The following example shows the properties of all indexes in a table in the AdventureWorks database.

```sql
SELECT i.name AS index_name
   , i.type_desc
   , i.is_unique
   , ds.type_desc AS filegroup_or_partition_scheme
   , ds.name AS filegroup_or_partition_scheme_name
   , i.ignore_dup_key
   , i.is_primary_key
   , i.is_unique_constraint
   , i.fill_factor
   , i.is_padded
   , i.is_disabled
   , i.allow_row_locks
   , i.allow_page_locks
   , i.has_filter
   , i.filter_definition
FROM sys.indexes AS i
   INNER JOIN sys.data_spaces AS ds
      ON i.data_space_id = ds.data_space_id
   WHERE is_hypothetical = 0 AND i.index_id <> 0
       AND i.object_id = OBJECT_ID('HumanResources.Employee')
;
```

#### To set the properties of an index

The following examples set the properties of indexes in the AdventureWorks database.
