OGRLayerH OGR_DS_ExecuteSQL	(	OGRDataSourceH	hDS,
		const char *	pszSQLCommand,
		OGRGeometryH	hSpatialFilter,
		const char *	pszDialect
	)

Execute an SQL statement against the data store.

The result of an SQL query is either NULL for statements that are in error, or that have no results set, or an OGRLayer handle representing a results set from the query. Note that this OGRLayer is in addition to the layers in the data store and must be destroyed with OGR_DS_ReleaseResultsSet() before the data source is closed (destroyed).

For more information on the SQL dialect supported internally by OGR review the OGR SQL document. Some drivers (ie. Oracle and PostGIS) pass the SQL directly through to the underlying RDBMS.

This function is the same as the C++ method OGRDataSource::ExecuteSQL();

Parameters:

	hDS	handle to the data source on which the SQL query is executed.
	pszSQLCommand	the SQL statement to execute.
	hSpatialFilter	handle to a geometry which represents a spatial filter.
	pszDialect	allows control of the statement dialect. By default it is assumed to be "generic" SQL, whatever that is.

Returns:: an handle to a OGRLayer containing the results of the query. Deallocate with OGR_DS_ReleaseResultsSet().

Parameters:

	hDS	handle to the data source from which to get the layer.
	iLayer	a layer number between 0 and OGR_DS_GetLayerCount()-1.

Returns:: an handle to the layer, or NULL if iLayer is out of range or an error occurs.

Referenced by OGR_DS_GetLayer().

OGRLayerH OGR_DS_GetLayerByName	(	OGRDataSourceH	hDS,
		const char *	pszLayerName
	)

Fetch a layer by name. The returned layer remains owned by the OGRDataSource and should not be deleted by the application.

Returns:: layer count.

References OGR_DS_GetLayerCount().

Referenced by OGR_DS_GetLayerCount().

const char * OGR_DS_GetName ( OGRDataSourceH hDS )

Returns the name of the data source. This string should be sufficient to open the data source if passed to the same OGRSFDriver that this data source was opened with, but it need not be exactly the same string that was used to open the data source. Normally this is a filename.

This function is the same as the C++ method OGRDataSource::GetName().

Parameters:

hDS

handle to the data source to get the name from.

Returns:: pointer to an internal name string which should not be modified or freed by the caller.

void OGR_DS_ReleaseResultSet	(	OGRDataSourceH	hDS,
		OGRLayerH	hLayer
	)

Release results of OGR_DS_ExecuteSQL().

This function should only be used to deallocate OGRLayers resulting from an OGR_DS_ExecuteSQL() call on the same OGRDataSource. Failure to deallocate a results set before destroying the OGRDataSource may cause errors.

This function is the same as the C++ method OGRDataSource::ReleaseResultsSet().

Parameters:

	hDS	an handle to the data source on which was executed an SQL query.
	hLayer	handle to the result of a previous OGR_DS_ExecuteSQL() call.

This function is the same as the C++ method OGRFeature::Clone().

Parameters:

hFeat

handle to the feature to clone.

Returns:: an handle to the new feature, exactly matching this feature.

References OGR_F_Clone().

Referenced by OGR_F_Clone().

OGRFeatureH OGR_F_Create ( OGRFeatureDefnH hDefn )

Feature factory.

Note that the OGRFeature will increment the reference count of it's defining OGRFeatureDefn. Destruction of the OGRFeatureDefn before destruction of all OGRFeatures that depend on it is likely to result in a crash.

This function is the same as the C++ method OGRFeature::OGRFeature().

Parameters:

hDefn

handle to the feature class (layer) definition to which the feature will adhere.

Returns:: an handle to the new feature object with null fields and no geometry.

Referenced by OGR_F_Create().

void OGR_F_Destroy ( OGRFeatureH hFeat )

Destroy feature

The feature is deleted, but within the context of the GDAL/OGR heap. This is necessary when higher level applications use GDAL/OGR from a DLL and they want to delete a feature created within the DLL. If the delete is done in the calling application the memory will be freed onto the application heap which is inappropriate.

This function is the same as the C++ method OGRFeature::DestroyFeature().

Parameters:

hFeat

handle to the feature to destroy.

This function is the same as the C++ method OGRFeature::DumpReadable().

Parameters:

	hFeat	handle to the feature to dump.
	fpOut	the stream to write to, such as strout.
