Property Value

A SqlCeCommand that is used during Fill to select records from data source for placement in the DataSet.

Remarks

When SelectCommand is assigned to a previously-created SqlCeCommand, the SqlCeCommand is not cloned. The SelectCommand maintains a reference to the previously-created SqlCeCommand object.

If the SelectCommand does not return any rows, no tables are added to the DataSet, and no exception is raised.

Example

The following example creates a SqlCeDataAdapter and sets some of its properties.

Dim da As New SqlCeDataAdapter()

Dim conn As New SqlCeConnection("Data Source = MyDatabase.sdf")
Dim cmd As New SqlCeCommand("SELECT * FROM Customers WHERE Country = @country", conn)

cmd.Parameters.Add("@country", SqlDbType.NVarChar, 15)
cmd.Parameters(0).Value = "UK"

da.SelectCommand = cmd

SqlCeDataAdapter da = new SqlCeDataAdapter();

SqlCeConnection conn = new SqlCeConnection("Data Source = MyDatabase.sdf");
SqlCeCommand cmd = new SqlCeCommand("SELECT * FROM Customers WHERE Country = @country", conn);

cmd.Parameters.Add("@country", SqlDbType.NVarChar, 15);
cmd.Parameters[0].Value = "UK";

da.SelectCommand = cmd;
