'Declaration
 
Public Function New( _
   ByVal selectCommand As DB2Command _

   DB2Command selectCommand
)

Parameters

selectCommand: A DB2Command that contains SQL SELECT statement, and is set as the SelectCommand property of the DB2DataAdapter.

Remarks

This implementation of the DB2DataAdapter constructor sets the SelectCommand property to the value specified in the parameter.

When you create an instance of DB2DataAdapter, 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 DB2DataAdapter, sets some of its properties, retrieves data from a table, and displays it.

csharp

public void CreateDataAdapter(DB2Connection db2Connection)
{
  DB2Command db2Command = new DB2Command("SELECT DeptNo, DName FROM Dept", db2Connection);
  DB2DataAdapter myAdapter = new DB2DataAdapter(db2Command);
  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();
  }
}

Visual Basic

Public Sub CreateDataAdapter(ByVal db2Connection As DB2Connection)
  Dim db2Command As DB2Command = New DB2Command("SELECT DeptNo, DName FROM Dept", db2Connection)
  Dim myAdapter As DB2DataAdapter = New DB2DataAdapter(db2Command)
  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
