OracleParameter()

Initializes a new instance of the OracleParameter class.

public:
 OracleParameter();

public OracleParameter ();

Public Sub New ()

Applies to

OracleParameter(String, OracleType)

Initializes a new instance of the OracleParameter class that uses the parameter name and data type.

public:
 OracleParameter(System::String ^ name, System::Data::OracleClient::OracleType oracleType);

public OracleParameter (string name, System.Data.OracleClient.OracleType oracleType);

new System.Data.OracleClient.OracleParameter : string * System.Data.OracleClient.OracleType -> System.Data.OracleClient.OracleParameter

Public Sub New (name As String, oracleType As OracleType)

Parameters

name: String

The name of the parameter.

oracleType: OracleType

One of the OracleType values.

Exceptions

ArgumentException

The value supplied in the oracleType parameter is an invalid back-end data type.

Examples

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

public void CreateOracleParameter()
{
   OracleParameter parameter = new OracleParameter("DName",OracleType.VarChar);
   parameter.Direction = ParameterDirection.Output;
   parameter.Size = 14;
}

Public Sub CreateOracleParameter()
    Dim parameter As New OracleParameter("DName", OracleType.VarChar)
    parameter.Direction = ParameterDirection.Output
    parameter.Size = 14
End Sub

Applies to

OracleParameter(String, Object)

Initializes a new instance of the OracleParameter class that uses the parameter name and an OracleParameter object.

public:
 OracleParameter(System::String ^ name, System::Object ^ value);

public OracleParameter (string name, object value);

new System.Data.OracleClient.OracleParameter : string * obj -> System.Data.OracleClient.OracleParameter

Public Sub New (name As String, value As Object)

Parameters

name: String

The name of the parameter.

value: Object

An OracleParameter object.

Remarks

When you specify an Object in the value parameter, the DbType is inferred from the Microsoft .NET Framework type of the Object.

Use caution when you are using this overload of the OracleParameter constructor. 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 Microsoft Visual C# example demonstrates.

Parameter = new OracleParameter("pname", Convert.ToInt32(0));

If you do not perform this conversion, the compiler will assume that you are trying to call the OracleParameter(string, OracleType) constructor overload.

Applies to

OracleParameter(String, OracleType, Int32)

Initializes a new instance of the OracleParameter class that uses the parameter name, data type, and length.

public:
 OracleParameter(System::String ^ name, System::Data::OracleClient::OracleType oracleType, int size);

public OracleParameter (string name, System.Data.OracleClient.OracleType oracleType, int size);

new System.Data.OracleClient.OracleParameter : string * System.Data.OracleClient.OracleType * int -> System.Data.OracleClient.OracleParameter

Public Sub New (name As String, oracleType As OracleType, size As Integer)

Parameters

name: String

The name of the parameter.

oracleType: OracleType

One of the OracleType values.

size: Int32

The length of the parameter.

Exceptions

ArgumentException

The value supplied in the oracleType parameter is an invalid back-end data type.

Examples

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

public void CreateOracleParameter()
{
   OracleParameter parameter = new OracleParameter("DName",OracleType.VarChar,14);
   parameter.Direction = ParameterDirection.Output;
}

Public Sub CreateOracleParameter()
    Dim parameter As New OracleParameter("DName", OracleType.VarChar, 14)
    parameter.Direction = ParameterDirection.Output
End Sub

Applies to

OracleParameter(String, OracleType, Int32, String)

public:
 OracleParameter(System::String ^ name, System::Data::OracleClient::OracleType oracleType, int size, System::String ^ srcColumn);

public OracleParameter (string name, System.Data.OracleClient.OracleType oracleType, int size, string srcColumn);

new System.Data.OracleClient.OracleParameter : string * System.Data.OracleClient.OracleType * int * string -> System.Data.OracleClient.OracleParameter
