SqlCeResultSet Class

An updateable, scrollable, and bindable cursor.

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

public class SqlCeResultSet : SqlCeDataReader, IEnumerable, IListSource
/** @attribute DefaultMemberAttribute("Item") */ 
public class SqlCeResultSet extends SqlCeDataReader implements IEnumerable, IListSource
public class SqlCeResultSet extends SqlCeDataReader implements IEnumerable, IListSource

In earlier versions of SQL Server Compact 3.5 SP1, 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 Compact 3.5 SP1, 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.

The default position of the SqlCeDataReader is prior to the first record. To begin accessing any data, you must call Read. The first Read will position the cursor to the first record. The behaviour is different from that of SqlCeResultSet.Read method. The default position of the SqlCeResultSet is the first record. Calling SqlCeResultSet.Read method immediately after creating the SqlCeResultSet will move the cursor to the second record.


In the following example, a new SQL Server Compact 3.5 SP1 database is created. A SqlCeResultSet is then initialized to populate the dataset with data.

SqlCeConnection conn = null;


    SqlCeEngine engine = new SqlCeEngine("Data Source = Test.sdf");

    conn = new SqlCeConnection("Data Source = Test.sdf");

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

    cmd.CommandText = "SELECT * FROM myTable";

    SqlCeResultSet rs = cmd.ExecuteResultSet(ResultSetOptions.Updatable | 

    SqlCeUpdatableRecord rec = rs.CreateRecord();

    rec.SetInt32(0, 34);
    rec.SetDecimal(1, (decimal)44.66);
    rec.SetString(2, "Sample text");
