   value : Object
);

parameterName

The name of the parameter.

dbType

One of the OleDbType values.

size

The width of the parameter.

direction

One of the ParameterDirection values.

isNullable

true if the value of the field can be null; otherwise, false.

precision

The total number of digits to which Value is resolved.

scale

The number of decimal places to which Value is resolved.

srcColumn

The name of the source column.

srcVersion

One of the DataRowVersion values.

value

An Object that is the value of the OleDbParameter.

The following example initializes an OleDbParameter and displays the ParameterName.

public void CreateOleDbParameter ( ) {
   OleDbParameter myParam = new OleDbParameter ( "Description", OleDbType.VarChar,
      11, ParameterDirection.Output, true, 0, 0, "Description",
      DataRowVersion.Current,"garden hose" );
   Response.Write ( myParam.ToString ( ) );
}

Public Sub CreateOleDbParameter ( )
   Dim myParam As New OleDbParameter ( "Description", OleDbType.VarChar, _
      11, ParameterDirection.Output, True, 0, 0, "Description", _
      DataRowVersion.Current, "garden hose" )
   Response.Write ( myParam.ToString ( ) )
End Sub
