Gets or sets a Transact-SQL statement or stored procedure used to select records in the data source.

[Visual Basic]
Public Shadows Property SelectCommand As SqlCommand
[C#]
public new SqlCommand SelectCommand {get; set;}
[C++]
public: __property SqlCommand* get_SelectCommand();
public: __property void set_SelectCommand(SqlCommand*);
[JScript]
public hide function get SelectCommand() : SqlCommand;
public function set SelectCommand(SqlCommand);

Property Value

A SqlCommand used during Fill to select records from the database for placement in the DataSet.

Remarks

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

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

Example

[Visual Basic, C#] The following example creates a SqlDataAdapter and sets the SelectCommand and InsertCommand properties. It assumes you have already created a SqlConnection object.

[Visual Basic] 
Public Shared Function CreateCustomerAdapter(conn As SqlConnection) As SqlDataAdapter 
  
  Dim da As SqlDataAdapter = New SqlDataAdapter()
  Dim cmd As SqlCommand

  ' Create the SelectCommand.

  cmd = New SqlCommand("SELECT * FROM Customers " & _
                       "WHERE Country = @Country AND City = @City", conn)

  cmd.Parameters.Add("@Country", SqlDbType.NVarChar, 15)
  cmd.Parameters.Add("@City", SqlDbType.NVarChar, 15)

  da.SelectCommand = cmd

  ' Create the InsertCommand.

  cmd = New SqlCommand("INSERT INTO Customers (CustomerID, CompanyName) " & _
                       "VALUES (@CustomerID, @CompanyName)", conn)

  cmd.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID")
  cmd.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName")

  da.InsertCommand = cmd

  Return da
End Function

[C#] 
public static SqlDataAdapter CreateCustomerAdapter(SqlConnection conn)
{
  SqlDataAdapter da = new SqlDataAdapter();
  SqlCommand cmd;

  // Create the SelectCommand.

  cmd = new SqlCommand("SELECT * FROM Customers " +
                       "WHERE Country = @Country AND City = @City", conn);

  cmd.Parameters.Add("@Country", SqlDbType.NVarChar, 15);
  cmd.Parameters.Add("@City", SqlDbType.NVarChar, 15);

  da.SelectCommand = cmd;

  // Create the InsertCommand.

  cmd = new SqlCommand("INSERT INTO Customers (CustomerID, CompanyName) " +
                       "VALUES (@CustomerID, @CompanyName)", conn);

  cmd.Parameters.Add("@CustomerID", SqlDbType.NChar, 5, "CustomerID");
  cmd.Parameters.Add("@CompanyName", SqlDbType.NVarChar, 40, "CompanyName");

  da.InsertCommand = cmd;

  return da;
}
