In This Topic

Initializes a new instance of the DynamicsDataAdapter class with the specified DynamicsCommand as the %% property.

Syntax

Visual Basic
C#

'Declaration
 
Public Function New( _
   ByVal selectCommand As DynamicsCommand _
)

public DynamicsDataAdapter( 
   DynamicsCommand selectCommand
)

Parameters

selectCommand: A DynamicsCommand that contains SQL SELECT statement, and is set as the SelectCommand property of the DynamicsDataAdapter.

Remarks

This implementation of the DynamicsDataAdapter constructor sets the SelectCommand property to the value specified in the parameter.

When you create an instance of DynamicsDataAdapter, 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 DynamicsDataAdapter, sets some of its properties, retrieves data from a table, and displays it.

csharp

public void CreateDataAdapter(DynamicsConnection dynamicsConnection)
{
  DynamicsCommand dynamicsCommand = new DynamicsCommand("SELECT DeptNo, DName FROM contact", dynamicsConnection);
  DynamicsDataAdapter myAdapter = new DynamicsDataAdapter(dynamicsCommand);
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
  DataSet myDataSet = new DataSet();
  myAdapter.Fill(myDataSet,"contact");
  //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();
  }
}

Visual Basic

Public Sub CreateDataAdapter(ByVal dynamicsConnection As DynamicsConnection)
  Dim dynamicsCommand As DynamicsCommand = New DynamicsCommand("SELECT DeptNo, DName FROM contact", dynamicsConnection)
  Dim myAdapter As DynamicsDataAdapter = New DynamicsDataAdapter(dynamicsCommand)
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey
  Dim myDataSet As DataSet = New DataSet
  myAdapter.Fill(myDataSet, "contact")
  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
