Gets the value of the specified field (column) as an Int64.

Syntax

'Declaration
 
Public Overrides NotOverridable Function GetInt64( _
   ByVal ordinal As Integer _
) As Long

'Usage
 
Dim instance As TdDataReader
Dim ordinal As Integer
Dim value As Long
 
value = instance.GetInt64(ordinal)

public override long GetInt64( 
   int ordinal
)

public:
int64 GetInt64( 
   int ordinal
) override

Returns the value of the specified field represented as a System.Int64 type.

Exceptions

Exception	Description
System.IndexOutOfRangeException	ordinal is less than zero or ordinal is equal to or greater than TdDataReader.FieldCount.
System.InvalidCastException	The field cannot be converted into System.Int64. A null field will result in an exception.
System.OverflowException	Conversion overflow. For example Teradata DECIMAL(38) might result in Overflow when converted to Decimal.
System.InvalidOperationException	CommandBehavior is set to SchemaOnly, or there is no data for the row or column, or preceding columns are no longer accessible.
System.ObjectDisposedException	The TdDataReader is closed.
TdException	The Advanced SQL Engine returned an error, or .NET Data Provider for Teradata detected an error.

Remarks

The .NET Data Provider for Teradata uses the .NET Framework class libraries to convert the underlying field to a System.Int64.

The Advanced SQL Engine does not have direct support for an eight-byte singed integer. The closest Teradata data type is DECIMAL(18,0).
