Provides access to members that return and modify the output spatial resolution.
IQueryFilter2 adds the SpatialResolution method to the IQueryFilter interface. The IQueryFilter2 interface allows the specification of the desired spatial resolution as part of the query. It can be used a filter criteria for data sources that support the filtering of feature data based on spatial resolution. Features whose geometry extent is smaller than the specified spatial resolution will not be returned.
| Description | ||
|---|---|---|
 |
AddField | Appends a single field name to the list of sub-fields. |
 |
OutputSpatialReference | The spatial reference in which to output geometry for a given field. |
 |
SpatialResolution | The spatial resolution in which to output geometry. |
|
SubFields | The comma delimited list of field names for the filter. |
|
WhereClause | The where clause for the filter. |
| Interfaces | Description |
|---|---|
| IQueryFilter | Provides access to members that filter data based on attribute values and or relationships. |
| CoClasses and Classes | Description |
|---|---|
| ImageQueryFilter (esriCarto) | An image query filter. |
| QueryFilter | Esri Query Filter object. |
| SpatialFilter | Esri Spatial Filter object. |
| TemporalQueryFilter (esriTrackingAnalyst) | Controls properties for the temporal query filter. |
| TimeQueryFilter (esriCarto) | TimeQueryFilter Class |
Note on ORDER BY and returning sorted data: To add ORDER BY and GROUP BY clauses to the attribute query the IQueryFilterDefinition::PostfixClause property can be used prior to creating the cursor. This will only work with ArcSDE and Personal Geodatabase.
