# CRowset::SetData
Sets data values in one or more columns of a row.  
  
## Syntax  
  
```  
  
      HRESULT SetData( ) const throw( );   
HRESULT SetData(  
   int nAccessor   
) const throw( );  
```  
  
#### Parameters  
 `nAccessor`  
 [in] The number of the accessor to use for accessing the data.  
  
## Return Value  
 A standard `HRESULT`.  
  
## Remarks  
 For the `SetData` form that accepts no arguments, all accessors are used for updating. You typically call **SetData** to set data values in columns in a row, then call [Update](../../data/oledb/crowset-update.md) to transmit those changes.  
  
 This method requires the optional interface `IRowsetChange`, which might not be supported on all providers; if this is the case, the method returns **E_NOINTERFACE**. You must also set **DBPROP_IRowsetChange** to `VARIANT_TRUE` before calling **Open** on the table or command containing the rowset.  
  
 The setting operation might fail if one or more columns is not writable. Modify your cursor map to correct this.  
  
## Requirements  
 **Header:** atldbcli.h
