java.lang.Object
- com.supermap.data.Recordset

```
public class Recordset
extends java.lang.Object
```
The recordset class.

Using this class, you can perform operations on the data in the vector dataset.

For the data that is stored in a file, the spatial geometry information and attribute information are stored separately. Actually, record set treats the file the same way as the database, that is to say, for the record set, it assumes all data are stored in a table, where the geometry and attribute information are stored together in the fields like a DBMS table does. Of course, there may be some background operations on the file data to make this assumption work, which we do not need to know, and this way, the record set is a subclass of that table, so that modifications can be done to the data in the record set. We can see that the record set provides a way to operate the data in the storing table. A row in the record set represents a feature or a record (for tabular vector data) , while a column of the record set is called a field.

There are two ways to get the recordset: one is selecting several geometric objects in the MapControl and converting the selection to the Recordset; the other is getting the recordset from a vector dataset. You can either return a recordset from a vector dataset through the DatasetVector.getRecordset() method , or with the query statement. The difference is that the DatasetVector.getRecordset() method returns all spatial and attribute information of all records of the dataset; however, the query statement returns the records satisfying the statement. .
Note: Once the Recordset object is got by user, the resources occupied by this object should be released.
Example:
The following example demonstrates how to delete and add a record. Suppose opening a workspace object which contains a datasource object. workspace .
```
 public void recordsetTest() {
        // Get the World region dataset and Example region dataset.
        DatasetVector dataset_world = (DatasetVector) datasource.getDatasets().get("World");
        DatasetVector dataset = (DatasetVector) datasource.getDatasets().get("Example");
 
        //Gets all recordsets related to "Example" and the record whose SmID is 1 in the World dataset
        Recordset recordset = dataset.getRecordset(false, CursorType.DYNAMIC);
        QueryParameter parameter = new QueryParameter();
        parameter.setAttributeFilter("SmID=1");
        parameter.setCursorType(CursorType.STATIC);
        Recordset recordset_world = dataset_world.query(parameter);
 
        //Move the record position to the first one
        recordset.moveFirst();
 
        //Deletes the current record
        recordset.delete();
 
        //Add the record whose SmID is 1 in the World dataset to the recordset and commit it
        Geometry geometry = recordset_world.getGeometry();
        recordset.update();
        recordset.addNew(geometry);
        recordset.update();
 
        // Close recordset and release geometry and recordset.
        recordset.close();
        geometry.dispose();
        recordset.dispose();
        recordset_world.dispose();
 }
 
```
