InsertCommand Property (OracleDataAdapter)

In This Topic

Gets or sets an Oracle statement to insert new records into the data source.

Syntax

Visual Basic
C#

'Declaration
 
Public Shadows Property InsertCommand As OracleCommand

public new OracleCommand InsertCommand {get; set;}

Property Value

A OracleCommand used during an update operation to insert records in the data source that correspond to new rows in the System.Data.DataSet.

Remarks

During an update operation, if InsertCommand is not set and primary key information is present in the System.Data.DataSet, you can use the OracleCommandBuilder class to automatically generate InsertCommand, and additional commands needed to reconcile the System.Data.DataSet to the data source. To do this, set the SelectCommand property of the OracleDataAdapter. For more information see "Automatically Generated Commands" in the Microsoft .NET Framework SDK documentation.

Note: If execution of this command returns rows, these rows may be added to the System.Data.DataSet depending upon how you set the Devart.Common.DbCommandBase.UpdatedRowSource property of the OracleCommand object.

Example

The following example demonstrates how to retrieve and manipulate data using OracleDataAdapter.

csharp

public void UseDataAdapter(OracleConnection myConnection)
{
  OracleDataAdapter myAdapter = new OracleDataAdapter("SELECT DeptNo, DName FROM Test.Dept", myConnection);
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
  DataSet myDataSet = new DataSet();
  myAdapter.Fill(myDataSet,"Departments");
  object[] rowVals = new object[2];
  rowVals[0] = 40;
  rowVals[1] = "Operations";
  myDataSet.Tables["Departments"].Rows.Add(rowVals);
  myAdapter.InsertCommand = new OracleCommand("INSERT INTO Test.Dept (DeptNo, DName) " +
    "VALUES (:DeptNo, :DName)", myConnection);
        myAdapter.InsertCommand.Parameters.Add("DeptNo", OracleDbType.Integer, 0, "DeptNo");
  myAdapter.InsertCommand.Parameters.Add("DName", OracleDbType.VarChar, 15, "DName");
  myAdapter.Update(myDataSet,"Departments"); 
  //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 UseDataAdapter(ByVal myConnection As OracleConnection)
  Dim myAdapter As OracleDataAdapter = New OracleDataAdapter("SELECT DeptNo, DName FROM Test.Dept", myConnection)
  myAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey
  Dim myDataSet As DataSet = New DataSet
  myAdapter.Fill(myDataSet, "Departments")
  Dim rowVals(1) As Object
  rowVals(0) = "40"
  rowVals(1) = "Operations"
  myDataSet.Tables("Departments").Rows.Add(rowVals)
  myAdapter.InsertCommand = New OracleCommand("INSERT INTO Test.Dept (DeptNo, DName) " & _
      "VALUES (:DeptNo, :DName)", myConnection)
  myAdapter.InsertCommand.Parameters.Add("DeptNo", OracleDbType.Integer, 0, "DeptNo")
  myAdapter.InsertCommand.Parameters.Add("DName", OracleDbType.VarChar, 15, "DName")
  myAdapter.Update(myDataSet, "Departments")
  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
