OracleDataAdapter.InsertCommand Property

Gets or sets an SQL statement or stored procedure used to insert new records into the database.

Namespace: System.Data.OracleClient
Assembly: System.Data.OracleClient (in system.data.oracleclient.dll)

'Declaration
Public Property InsertCommand As OracleCommand
'Usage
Dim instance As OracleDataAdapter
Dim value As OracleCommand

value = instance.InsertCommand

instance.InsertCommand = value
/** @property */
public OracleCommand get_InsertCommand ()

/** @property */
public void set_InsertCommand (OracleCommand value)

public function get InsertCommand () : OracleCommand

public function set InsertCommand (value : OracleCommand)

Property Value

An OracleCommand used during an update operation to insert records in the database that correspond to new rows in the DataSet.

When the InsertCommand property is assigned to a previously created OracleCommand object, the OracleCommand is not cloned. Instead, InsertCommand maintains a reference to the previously created OracleCommand.

During an update operation, if InsertCommand is not set and primary key information is present in the DataSet, you can use the OracleCommandBuilder class to automatically generate InsertCommand, and additional commands needed to reconcile the DataSet to the database. To do this, set the SelectCommand property of the OracleDataAdapter. The generation logic also requires key column information to be present in the DataSet. For more information see Automatically Generating Commands.

NoteNote

If execution of this command returns rows, these rows may be added to the DataSet depending upon how you set the .Data.OracleClient.OracleCommand.UpdatedRowSource property of the OracleCommand object.

The following example creates an OracleDataAdapter and sets the SelectCommand and InsertCommand properties. It assumes you have already created an OracleConnection object.

[Visual Basic]

Public Shared Function CreateCustomerAdapter(conn As OracleConnection) As OracleDataAdapter 
  
  Dim da As OracleDataAdapter = New OracleDataAdapter()
  Dim cmd As OracleCommand

  ' Create the SelectCommand.

  cmd = New OracleCommand("SELECT * FROM Dept " & _
                       "WHERE DName = :pDName AND Loc = :pLoc", conn)

  cmd.Parameters.Add("pDName", OracleType.NVarChar, 14)
  cmd.Parameters.Add("pLoc", OracleType.NVarChar, 13)

  da.SelectCommand = cmd

  ' Create the InsertCommand.

  cmd = New OracleCommand("INSERT INTO Dept (DeptNo, DName) " & _
                       "VALUES (:pDeptNo, :pDName)", conn)

  cmd.Parameters.Add("pDeptNo", OracleType.Number, 2, "DeptNo")
  cmd.Parameters.Add("pDName", OracleType.NVarChar, 14, "DName")

  da.InsertCommand = cmd

  Return da
End Function

[C#]

public static OracleDataAdapter CreateCustomerAdapter(OracleConnection conn)
{
  OracleDataAdapter da = new OracleDataAdapter();
  OracleCommand cmd;

  // Create the SelectCommand.

  cmd = new OracleCommand("SELECT * FROM Dept " +
                       "WHERE DName = :pDName AND Loc = :pLoc", conn);

  cmd.Parameters.Add("pDName", OracleType.NVarChar, 14);
  cmd.Parameters.Add("pLoc", OracleType.NVarChar, 13);

  da.SelectCommand = cmd;

  // Create the InsertCommand.

  cmd = new OracleCommand("INSERT INTO Dept (DeptNo, DName) " +
                       "VALUES (:pDeptNo, :pDName)", conn);

  cmd.Parameters.Add("pDeptNo", OracleType.Number, 2, "DeptNo");
  cmd.Parameters.Add("pDName", OracleType.NVarChar, 14, "DName");

  da.InsertCommand = cmd;

  return da;
