Answer 1

For your specific table, please try the code below. It assumes USERID is the "ID" from your original question and CHECKTIME is the "Time". Hope this works for you!

DECLARE @Seconds INT = 120
;WITH Logs AS (
    SELECT
        [USERID] AS ID,
        [CHECKTIME] AS [Time],
        ROW_NUMBER() OVER (PARTITION BY ID ORDER BY [Time]) AS RowNum
    FROM [NEWFP].[dbo].[CHECKINOUT] L
)
    DELETE L2
    FROM Logs L1
        INNER JOIN Logs L2
            ON L1.ID = L2.ID
                AND L1.RowNum = L2.RowNum - 1
    WHERE DATEDIFF(SS, L1.[Time], L2.[Time]) < @Seconds
