Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Overrides NotOverridable Function GetBoolean( _
   ByVal ordinal As Integer _
) As Boolean

'Usage
 
Dim instance As TdDataReader
Dim ordinal As Integer
Dim value As Boolean
 
value = instance.GetBoolean(ordinal)

public override bool GetBoolean( 
   int ordinal
)

public:
bool GetBoolean( 
   int ordinal
) override

Parameters

ordinal: Column ordinal (see TdDataReader.GetOrdinal).

Return Value

Returns the value of the specified field represented as a System.Boolean 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.Boolean. A null field will result in an exception.
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

Teradata does not directly support the Boolean data type. Therefore, the .NET Data Provider for Teradata uses the .NET Framework class libraries to convert the underlying field to System.Boolean.

Requirements

Target Platforms: Windows 8.1, Windows 10, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019
