# sp_updatestats (Transact-SQL)
[!INCLUDE[tsql-appliesto-ss2008-asdb-xxxx-xxx_md](../../includes/tsql-appliesto-ss2008-asdb-xxxx-xxx-md.md)]

  Runs UPDATE STATISTICS against all user-defined and internal tables in the current database.  
  
 For more information about UPDATE STATISTICS, see [UPDATE STATISTICS (Transact-SQL)](../../t-sql/statements/update-statistics-transact-sql.md). For more information about statistics, see [Statistics](../../relational-databases/statistics/statistics.md).

|**Applies to**: [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] ([!INCLUDE[ssKatmai](../../includes/sskatmai-md.md)] through [current version](http://go.microsoft.com/fwlink/p/?LinkId=299658)), [!INCLUDE[ssSDSfull](../../includes/sssdsfull-md.md)].|

## Syntax  
  
```  
  
sp_updatestats [ [ @resample = ] 'resample']  
```  
  
## Return Code Values  
 0 (success) or 1 (failure)  
  
## Arguments  
 [ **@resample** =] **'resample'**  
 Specifies that **sp_updatestats** will use the RESAMPLE option of the [UPDATE STATISTICS](../../t-sql/statements/update-statistics-transact-sql.md) statement. If **'resample'** is not specified, **sp_updatestats** updates statistics by using the default sampling. **resample** is **varchar(8)** with a default value of NO.  
  
## Remarks  
 **sp_updatestats** executes UPDATE STATISTICS, by specifying the ALL keyword, on all user-defined and internal tables in the database. sp_updatestats displays messages that indicate its progress. When the update is completed, it reports that statistics have been updated for all tables.  
  
 sp_updatestats updates statistics on disabled nonclustered indexes and does not update statistics on disabled clustered indexes.  
  
 For disk-based tables, **sp_updatestats** updates only the statistics that require updating based on the **modification_counter** information in the **sys.dm_db_stats_properties** catalog view, thus avoiding unnecessary updates of statistics on unchanged rows. Statistics on memory-optimized tables are always updated when executing **sp_updatestats**. Therefore do not execute **sp_updatestats** more than necessary.  
  
 **sp_updatestats** can trigger a recompile of stored procedures or other compiled code. However, **sp_updatestats** might not cause a recompile, if only one query plan is possible for the tables referenced and the indexes on them. A recompilation would be unnecessary in these cases even if statistics are updated.  
  
 For databases with a compatibility level below 90, executing **sp_updatestats** does not preserve the latest NORECOMPUTE setting for specific statistics. For databases with a compatibility level of 90 or higher, sp_updatestats does preserve the latest NORECOMPUTE option for specific statistics. For more information about disabling and re-enabling statistics updates, see [Statistics](../../relational-databases/statistics/statistics.md).  
  
## Permissions  
 Requires membership in the **sysadmin** fixed server role, or ownership of the database (**dbo**).  
  
## Examples  
 The following example updates the statistics for tables in the [!INCLUDE[ssSampleDBobject](../../includes/sssampledbobject-md.md)] database.  
  
```  
USE AdventureWorks2012;  
GO  
EXEC sp_updatestats;   
```
