# IRowsetInfoImpl Class

Provides an implementation for the [IRowsetInfo](/previous-versions/windows/desktop/ms724541(v=vs.85)) interface.

## Syntax

```cpp
template <class T, class PropClass = T>
class ATL_NO_VTABLE IRowsetInfoImpl :
   public IRowsetInfo,
   public CUtlProps<PropClass>
```

### Parameters

*T*<br/>
Your class, derived from `IRowsetInfoImpl`.

*PropClass*<br/>
A user-definable property class that defaults to *T*.

## Requirements

**Header:** altdb.h

## Members

### Interface Methods

| Name | Description |
|-|-|
|[GetProperties](#getproperties)|Returns the current settings of all properties supported by the rowset.|
|[GetReferencedRowset](#getreferencedrowset)|Returns an interface pointer to the rowset to which a bookmark applies.|
|[GetSpecification](#getspecification)|Returns an interface pointer on the object (command or session) that created this rowset.|

## Remarks

A mandatory interface on rowsets. This class implements the rowset properties by using the [property set map](./macros-for-ole-db-provider-templates.md#begin_propset_map) defined in your command class. Although the rowset class appears to be using the command class' property sets, the rowset is supplied with its own copy of the run-time properties, when it is created by a command or session object.

## <a name="getproperties"></a> IRowsetInfoImpl::GetProperties

Returns the current settings for properties in the `DBPROPSET_ROWSET` group.

### Syntax

```cpp
STDMETHOD (GetProperties )(const ULONG cPropertyIDSets,
   const DBPROPIDSET rgPropertyIDSets[],
   ULONG* pcPropertySets,
   DBPROPSET** prgPropertySets);
```

#### Parameters

See [IRowsetInfo::GetProperties](/previous-versions/windows/desktop/ms719611(v=vs.85)) in the *OLE DB Programmer's Reference*.

## <a name="getreferencedrowset"></a> IRowsetInfoImpl::GetReferencedRowset

Returns an interface pointer to the rowset to which a bookmark applies.

### Syntax

```cpp
STDMETHOD (GetReferencedRowset )(DBORDINAL iOrdinal,
   REFIID riid,
   IUnknown** ppReferencedRowset);
```

#### Parameters

See [IRowsetInfo::GetReferencedRowset](/previous-versions/windows/desktop/ms721145(v=vs.85)) in the *OLE DB Programmer's Reference*. The *iOrdinal* parameter must be a bookmark column.

## <a name="getspecification"></a> IRowsetInfoImpl::GetSpecification

Returns an interface pointer on the object (command or session) that created this rowset.

### Syntax

```cpp
STDMETHOD (GetSpecification )(REFIID riid,
   IUnknown** ppSpecification);
```

#### Parameters

See [IRowsetInfo::GetSpecification](/previous-versions/windows/desktop/ms716746(v=vs.85)) in the *OLE DB Programmer's Reference*.

### Remarks

Use this method with [IGetDataSourceImpl](../../data/oledb/igetdatasourceimpl-class.md) to retrieve properties from the data source object.
