OracleDataAdapter Constructor (OracleCommand)

Initializes a new instance of the OracleDataAdapter class with the specified SQL SELECT statement.

Namespace:  System.Data.OracleClient
Assembly:  System.Data.OracleClient (in System.Data.OracleClient.dll)

public:
OracleDataAdapter(
	OracleCommand^ selectCommand
)

Parameters

selectCommand
Type: System.Data.OracleClient::OracleCommand

An OracleCommand that is an SQL SELECT statement or stored procedure, and is set as the SelectCommand property of the OracleDataAdapter.

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

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

Properties

Initial value

MissingMappingAction

MissingMappingAction.Passthrough

MissingSchemaAction

MissingSchemaAction.Add

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

The following example creates an OracleDataAdapter and sets some of its properties.

[Visual Basic]

Public Sub CreateOracleDataAdapter()
    Dim myOracleConnection As OracleConnection = New OracleConnection("Data Source=Oracle8i;Integrated Security=yes")
    Dim myOracleCommand As OracleCommand = New OracleCommand("SELECT DeptNo, DName FROM Dept", myOracleConnection)
    Dim custDA As OracleDataAdapter = New OracleDataAdapter(myOracleCommand)
    custDA.MissingSchemaAction = MissingSchemaAction.AddWithKey
   
    custDA.InsertCommand = New OracleCommand("INSERT INTO Dept (DeptNo, DName) " & _
                                            "VALUES (:pDeptNo, :pDName)", myOracleConnection)
    custDA.UpdateCommand = New OracleCommand("UPDATE Dept SET DeptNo = :pDeptNo, DName = :pDName " & _
                                            "WHERE DeptNo = :pDeptNo", myOracleConnection)
    custDA.DeleteCommand = New OracleCommand("DELETE FROM Dept WHERE DeptNo = :pDeptNo", myOracleConnection)

    custDA.InsertCommand.Parameters.Add("pDeptNo", OracleType.Number, 2, "DeptNo")
    custDA.InsertCommand.Parameters.Add("pDName", OracleType.VarChar, 14, "DName")
 
    custDA.UpdateCommand.Parameters.Add("pDeptNo", OracleType.Number, 2, "DeptNo")
    custDA.UpdateCommand.Parameters.Add("pDName", OracleType.VarChar, 14, "DName")
    custDA.UpdateCommand.Parameters.Add("poldDeptNo", OracleType.Number, 2, "DeptNo").SourceVersion = DataRowVersion.Original

    custDA.DeleteCommand.Parameters.Add("pDeptNo", OracleType.Number, 2, "DeptNo").SourceVersion = DataRowVersion.Original
End Sub
