LessThan Method (TdPeriodTimestamp)



Teradata.Client.Provider Namespace > TdPeriodTimestamp Structure : LessThan Method
An instance of TdPeriodTimestamp.
An instance of TdPeriodTimestamp.
Compares two TdPeriodTimestamp structures to determine whether the left operand is less than the right operand.
Syntax
'Declaration
 
Public Shared Function LessThan( _
   ByVal left As TdPeriodTimestamp, _
   ByVal right As TdPeriodTimestamp _
) As Boolean
'Usage
 
Dim left As TdPeriodTimestamp
Dim right As TdPeriodTimestamp
Dim value As Boolean
 
value = TdPeriodTimestamp.LessThan(left, right)
public static bool LessThan( 
   TdPeriodTimestamp left,
   TdPeriodTimestamp right
)
public:
static bool LessThan( 
   TdPeriodTimestamp left,
   TdPeriodTimestamp right
) 

Parameters

left
An instance of TdPeriodTimestamp.
right
An instance of TdPeriodTimestamp.

Return Value

A boolean is returned that indicates the result of the comparison.
Remarks

In order to perform this comparison the beginning and ending bounds of the left and right operands are compared against each other. The left is less than the right if the following is true:

    left.Begin < right.Begin || (left.Begin == right.Begin && left.End < right.End)

The value returned is true if the left is less than the right, false otherwise.

Return Value Description
true left and right are not TdPeriodTimestamp.Null and left is less than right.
false

left and / or right is Null

-or-

left is greater than or equal to right.

Comparison operators always returns false if one of the operands is Null. Therefore, you must not assume that the reverse condition is true. For example you cannot assume that the left operand is greater than or equal the right operand if the LessThan operator returns false.
