Gets all the records in the database.

Description

Returns a cursor of all the records in the dataset that match the optional where clause. An empty or null where clause means all records should be returned. The where clause will always be null if IPlugInWorkspaceFactoryHelper::CanSupportSQL returns false. The method should fail if there are no records.

The field map indicates which fields should be returned by the query. See IPlugInCursorHelper::QueryValues and IPlugInFastQueryValues::FastQueryValues for a description of how to use the field map.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

fetchAll in interface IPlugInDatasetHelper

Parameters:

classIndex - The classIndex (in)

whereClause - The whereClause (in)

fieldMap - A Variant (in)

Returns:

A reference to a com.esri.arcgis.geodatabase.IPlugInCursorHelper

fetchByEnvelope

public IPlugInCursorHelper fetchByEnvelope(int classIndex,
                                           IEnvelope env,
                                           boolean strictSearch,
                                           java.lang.String whereClause,
                                           java.lang.Object fieldMap)
                                    throws java.io.IOException,
                                           AutomationException

Gets the records within the envelope (or the full extent if the envelope is null).

Description

Returns a record set of all records that are in the envelope and that match the optional where clause. The where clause will always be null if IPlugInWorkspaceFactoryHelper::CanSupportSQL returns false. The method should fail if there are no records in the envelope that match the optional where clause.

Fieldmap indicates which fields should be returned by the query. See IPlugInCursorHelper::QueryValues and IPlugInFastQueryValues::FastQueryValues for a description of how to use the field map.

Many data sources use spatial indexes or other spatial organization methods. If strictSearch is false, these data sources should return a cursor containing all the records which are in indexes or blocks within the query envelope. If strictSearch is true, the cursor should contain only the records within the envelope. Data sources that don’t use indexes or blocks may ignore this parameter.

Remarks

The FetchByEnvelope function returns all records in the Dataset if the Envelope parameter given is Nothing.
