-- step-by-step workings: calculate 7am of monday last week and 7am of monday this week
SELECT *
FROM (SELECT DTToday = GETDATE()) d
CROSS APPLY (SELECT NoOfDaysSinceMonday = DATEDIFF(DD,0,DTToday)%7) x1
CROSS APPLY (SELECT DTMondayLastWeek = DATEADD(DD,-(NoOfDaysSinceMonday+7),DTToday)) x2
CROSS APPLY (SELECT MondayLastWeek = DATEADD(HH,7,CAST(CAST(DTMondayLastWeek AS DATE) AS DATETIME))) x3
CROSS APPLY (SELECT MondayThisWeek = DATEADD(DD,7,x3.MondayLastWeek)) x4
-- solution:
SELECT *
FROM dbo.DocketTB
CROSS APPLY (
SELECT MondayLastWeek = DATEADD(hh,7,CAST(CAST(DATEADD(DD,-((DATEDIFF(DD,0,GETDATE())%7)+7),GETDATE()) AS DATE) AS DATETIME))
) x1
WHERE Docket_EngFinish BETWEEN x1.MondayLastWeek AND DATEADD(DD,7,x1.MondayLastWeek)
