SqlCeResultSet Class

An updateable, scrollable, and bindable cursor.

Namespace: System.Data.SqlServerCe
Assembly: System.Data.SqlServerCe (in system.data.sqlserverce.dll)

Public Class SqlCeResultSet
	Inherits SqlCeDataReader
	Implements IEnumerable, IListSource
Dim instance As SqlCeResultSet

public class SqlCeResultSet extends SqlCeDataReader implements IEnumerable, IListSource
public class SqlCeResultSet extends SqlCeDataReader implements IEnumerable, IListSource

In previous versions of SQL Server CE, to bind controls to data you had to use a DataSet. While a SqlCeDataReader provides better performance than a DataSet, it is a forward-only, non-updateable cursor. In SQL Server 2005 Mobile Edition, the SqlCeResultSet provides a combination of functionality: the updateability and scrollability of the DataSet plus performance similar to a SqlCeDataReader.

To create a SqlCeResultSet, you must call the ExecuteResultSet method rather than using the object's constructor.

The ResultSetOptions let you specify the scrollabilty, updatability, and sensitivity (which determines if the SqlCeResultSet sees changes made by itself or others) of the SqlCeResultSet.

In the following example, a new SQL Server Mobile database is created. A SqlCeResultSet is then initialized to populate the dataset with data.

Dim conn As SqlCeConnection = Nothing


    Dim engine As New SqlCeEngine("Data Source = Test.sdf")

    conn = New SqlCeConnection("Data Source = Test.sdf")

    Dim cmd As SqlCeCommand = conn.CreateCommand()
    cmd.CommandText = "CREATE TABLE myTable (col1 INT, col2 MONEY, col3 NVARCHAR(200))"

    cmd.CommandText = "SELECT * FROM myTable"

    Dim rs As SqlCeResultSet = cmd.ExecuteResultSet(ResultSetOptions.Updatable Or ResultSetOptions.Scrollable)

    Dim rec As SqlCeUpdatableRecord = rs.CreateRecord()

    rec.SetInt32(0, 34)
    rec.SetDecimal(1, System.Convert.ToDecimal(44.66))
    rec.SetString(2, "Sample text")

Catch e As Exception
End Try
