override this.Add : System.Data.OracleClient.OracleParameter -> System.Data.OracleClient.OracleParameter

Public Function Add (value As OracleParameter) As OracleParameter

Parameters

value: OracleParameter

The OracleParameter to add to the collection.

Returns

OracleParameter

A reference to the new OracleParameter object.

Exceptions

ArgumentException

The OracleParameter specified in the value parameter is already added to this or another OracleParameterCollection.

ArgumentNullException

public void CreateOracleParamColl() {
    OracleCommand command = new OracleCommand(
        "SELECT Ename, DeptNo FROM Emp WHERE EmpNo = :pEmpNo", connection);
    OracleParameterCollection paramCollection = command.Parameters;
    object parameter = new OracleParameter("pEmpNo", OracleType.Number);
    int pIndex = paramCollection.Add(parameter);
 }

Public Sub CreateOracleParamColl(connection As OracleConnection)
  Dim command As New OracleCommand( _
    "SELECT Ename, DeptNo FROM Emp WHERE EmpNo = :pEmpNo", connection)

A reference to the new OracleParameter object.

Examples

The following example creates an OracleParameterCollection, adds instances of OracleParameter to the collection, and returns a reference to the new OracleParameter.

public void CreateOracleParamColl() {

Caution

Add(String parameterName, Object value) has been deprecated. Use AddWithValue(String parameterName, Object value). http://go.microsoft.com/fwlink/?linkid=14202

Adds an OracleParameter to the OracleParameterCollection given the parameter name and value.

public:
 System::Data::OracleClient::OracleParameter ^ Add(System::String ^ parameterName, System::Object ^ value);

public System.Data.OracleClient.OracleParameter Add (string parameterName, object value);

[System.Obsolete("Add(String parameterName, Object value) has been deprecated.  Use AddWithValue(String parameterName, Object value).  http://go.microsoft.com/fwlink/?linkid=14202", false)]
public System.Data.OracleClient.OracleParameter Add (string parameterName, object value);

member this.Add : string * obj -> System.Data.OracleClient.OracleParameter

[<System.Obsolete("Add(String parameterName, Object value) has been deprecated.  Use AddWithValue(String parameterName, Object value).  http://go.microsoft.com/fwlink/?linkid=14202", false)>]
override this.Add : string * obj -> System.Data.OracleClient.OracleParameter

Public Function Add (parameterName As String, value As Object) As OracleParameter

Parameters

parameterName: String

The name of the parameter.

value: Object

The Value of the OracleParameter to add to the collection.

Returns

OracleParameter

A reference to the new OracleParameter object.

Attributes: ObsoleteAttribute

Exceptions

InvalidCastException

The value parameter is not an OracleParameter.

Remarks

Use caution when using this overload of the Add method to specify integer parameter values. Because this overload takes a value of type Object, you must convert the integral value to an Object type when the value is zero, as the following C# example demonstrates.

parameters.Add("pname", Convert.ToInt32(0));

If you do not perform this conversion, the compiler will assume you are attempting to call the OracleParameterCollection.Add (string, OracleType) overload.

Applies to

Add(String, OracleType, Int32)

Adds an OracleParameter to the OracleParameterCollection given the parameter name, data type, and column length.

public:
 System::Data::OracleClient::OracleParameter ^ Add(System::String ^ parameterName, System::Data::OracleClient::OracleType dataType, int size);

public System.Data.OracleClient.OracleParameter Add (string parameterName, System.Data.OracleClient.OracleType dataType, int size);

member this.Add : string * System.Data.OracleClient.OracleType * int -> System.Data.OracleClient.OracleParameter

override this.Add : string * System.Data.OracleClient.OracleType * int -> System.Data.OracleClient.OracleParameter

Public Function Add (parameterName As String, dataType As OracleType, size As Integer) As OracleParameter

Parameters

parameterName: String

dataType: OracleType

One of the OracleType values.

size: Int32

The length of the column.

Returns

OracleParameter

A reference to the new OracleParameter object.

public void CreateOracleParamColl(OracleConnection connection)
{
    OracleCommand command = new OracleCommand(
        "SELECT Ename, DeptNo FROM Emp WHERE EmpNo = :pEmpNo", connection);
    OracleParameterCollection paramCollection = command.Parameters;
    OracleParameter parameter = paramCollection.Add(
        "pEmpNo", OracleType.Number, 4);
}

Public Sub CreateOracleParamColl(connection As OracleConnection)
  Dim command As New OracleCommand( _
    "SELECT Ename, DeptNo FROM Emp WHERE EmpNo = :pEmpNo", connection)
  Dim paramCollection As OracleParameterCollection = command.Parameters
  Dim parameter As OracleParameter = paramCollection.Add( _
    "pEmpNo", OracleType.Number, 4)
End Sub

Applies to

Add(String, OracleType, Int32, String)

One of the OracleType values.

size: Int32

The length of the column.

srcColumn: String

The name of the source column.

Returns

OracleParameter

A reference to the new OracleParameter object.

Examples

    OracleCommand command = new OracleCommand(
        "SELECT Ename, DeptNo FROM Emp WHERE EmpNo = :pEmpNo", connection);
    OracleParameterCollection paramCollection = command.Parameters;
    OracleParameter parameter = paramCollection.Add(
        "pEmpNo", OracleType.Number, 5, "EmpNo");
}

Public Sub CreateOracleParamColl(connection As OracleConnection)
