SqlMethods.DateDiffSecond Method

Definition

Counts the number of second boundaries between two specified dates.

Overloads

DateDiffSecond(DateTime, DateTime)

Counts the number of second boundaries between two non-nullable dates.

DateDiffSecond(DateTimeOffset, DateTimeOffset)

Counts the number of second boundaries between two non-nullable dates.

DateDiffSecond(Nullable<DateTime>, Nullable<DateTime>)

Counts the number of second boundaries between two nullable dates.

DateDiffSecond(Nullable<DateTimeOffset>, Nullable<DateTimeOffset>)

Counts the number of second boundaries between two nullable dates.

Remarks

Corresponds to the SQL Server DATEDIFF function using second to specify the type of time boundary crossed. For more about this SQL Server function, see DATEDIFF.

DateDiffSecond(DateTime, DateTime)

Counts the number of second boundaries between two non-nullable dates.

public:
 static int DateDiffSecond(DateTime startDate, DateTime endDate);
public static int DateDiffSecond (DateTime startDate, DateTime endDate);
static member DateDiffSecond : DateTime * DateTime -> int
Public Shared Function DateDiffSecond (startDate As DateTime, endDate As DateTime) As Integer

Parameters

startDate
DateTime

The start date for the time period.

endDate
DateTime

The end date for the time period.

Returns

The number of second boundaries between the two specified dates.

Remarks

Corresponds to the SQL Server DATEDIFF function using second to specify the type of time boundary crossed. For more about this SQL Server function, see DATEDIFF.

Applies to

DateDiffSecond(DateTimeOffset, DateTimeOffset)

Counts the number of second boundaries between two non-nullable dates.

public:
 static int DateDiffSecond(DateTimeOffset startDate, DateTimeOffset endDate);
public static int DateDiffSecond (DateTimeOffset startDate, DateTimeOffset endDate);
static member DateDiffSecond : DateTimeOffset * DateTimeOffset -> int
Public Shared Function DateDiffSecond (startDate As DateTimeOffset, endDate As DateTimeOffset) As Integer

Parameters

startDate
DateTimeOffset

The start date for the time period.

endDate
DateTimeOffset

The end date for the time period.

Returns

The number of second boundaries between the two specified dates.

Remarks

Corresponds to the SQL Server DATEDIFF function using second to specify the type of time boundary crossed. For more about this SQL Server function, see DATEDIFF.

Applies to

DateDiffSecond(Nullable<DateTime>, Nullable<DateTime>)

Counts the number of second boundaries between two nullable dates.

public:
 static Nullable<int> DateDiffSecond(Nullable<DateTime> startDate, Nullable<DateTime> endDate);
public static int? DateDiffSecond (DateTime? startDate, DateTime? endDate);
static member DateDiffSecond : Nullable<DateTime> * Nullable<DateTime> -> Nullable<int>
Public Shared Function DateDiffSecond (startDate As Nullable(Of DateTime), endDate As Nullable(Of DateTime)) As Nullable(Of Integer)

Parameters

startDate
Nullable<DateTime>

The start date for the time period.

endDate
Nullable<DateTime>

The end date for the time period.

Returns

When both parameters are not null, returns the number of second boundaries between the two specified dates. When one or both parameters are null, returns a null value.

Remarks

static member DateDiffSecond : Nullable<DateTimeOffset> * Nullable<DateTimeOffset> -> Nullable<int>
Public Shared Function DateDiffSecond (startDate As Nullable(Of DateTimeOffset), endDate As Nullable(Of DateTimeOffset)) As Nullable(Of Integer)

Parameters

startDate
Nullable<DateTimeOffset>

The start date for the time period.

endDate
Nullable<DateTimeOffset>

The end date for the time period.

Returns
