    Syntax
    'Declaration
     
    Public Function New( _
       ByVal selectCommand As SqlCommand _
    )
    public SqlDataAdapter( 
       SqlCommand selectCommand
    )

    Parameters

    selectCommand
    A SqlCommand that contains SQL SELECT statement, and is set as the SelectCommand property of the SqlDataAdapter.
    Remarks
    This implementation of the SqlDataAdapter constructor sets the SelectCommand property to the value specified in the selectCommand parameter.

    When you create an instance of SqlDataAdapter, the following read/write properties are set to their default values, as shown in the table.

    Properties Default Value
    MissingMappingAction MissingMappingAction.Passthrough
    MissingSchemaAction MissingSchemaAction.Add

    You can change the value of any of these properties through a separate call to the property.

    Example
    The following example creates a SqlDataAdapter, sets some of its properties, retrieves data from a table, and displays it.
    public void CreateDataAdapter(SqlConnection myConnection)
    {
      SqlCommand myCommand = new SqlCommand("SELECT DeptNo, DName FROM Test.Dept", myConnection);
      SqlDataAdapter myAdapter = new SqlDataAdapter(myCommand);
      myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
      DataSet myDataSet = new DataSet();
      myAdapter.Fill(myDataSet,"Dept");
      //Get all data from all tables within the dataset
      foreach(DataTable myTable in myDataSet.Tables)
      {
        foreach(DataRow myRow in myTable.Rows)
        {
          foreach (DataColumn myColumn in myTable.Columns)
          {
            Console.Write(myRow[myColumn]+"\t");
          }
          Console.WriteLine();
        }
        Console.WriteLine();
      }
    }
    Public Sub CreateDataAdapter(ByVal myConnection As SqlConnection)
      Dim myCommand As SqlCommand = New SqlCommand("SELECT DeptNo, DName FROM Test.Dept", myConnection)
      Dim myAdapter As SqlDataAdapter = New SqlDataAdapter(myCommand)
      myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey
      Dim myDataSet As DataSet = New DataSet
      myAdapter.Fill(myDataSet, "Dept")
      Dim myTable As DataTable
      Dim myRow As DataRow
      Dim myColumn As DataColumn
      ' Get all data from all tables within the dataset
      For Each myTable In myDataSet.Tables
        For Each myRow In myTable.Rows
          For Each myColumn In myTable.Columns
            Console.Write(myRow(myColumn) & Chr(9))
          Next myColumn
          Console.WriteLine()
        Next myRow
        Console.WriteLine()
      Next myTable
    End Sub
