Of course you could combine the formulas to use less cells. If Date2 is an earlier date than Date1, the result is a negative number. Now you can use them to your heart's content. DAYS (date2 date1) Calculates the difference, in days, between two date values.

the last combines date+time into one cell (internally date and time are just float numbers, so you can add).

The next two (DATEVALUE,TIMEVALUE) parse a string as a date / a time.

The first two formulas (LEFT, RIGHT) split up the string into date and time, to parse them separately.

Then use DATEVALUE to convert the date, and TIMEVALUE to convert the time.

So first, you need to split your date+time string into two columns. It's just that there's no parsing function to parse date+time in one go. a day on the calender), or a time (wallclock time), not both.Įdit: Not true, this works just fine. In addition to that, a cell can only be a date (i.e. SET startdaydiff = datediff(ss, CASE d.specialinstanceĮnddaydiff = datediff(ss, convert(time(0), d.endday),ĪND convert(date, d.startday) = convert(date, si.startday)Įrland Sommarskog, SQL Server MVP, Table #draftĪND convert(date, d.startday) = convert(date, si.As Chris answered, your problem ist that your worksheet stores the dates as a text string, not as a date. Some of Calc's date and time functions return a 'date' or a 'time' ( for example TODAY() ). In Tools - Options - General you may set the range of years for which Calc will recognise years given 2 digits. Insert Into #draft (name, nameid, startday, endday, specialinstance) VALUES If we only enter 2 digits of the year (for example 07 instead of 2007) Calc needs to know whether we mean 2007 or 1907.

My desired updates would be since #draft.startday = 08:15 I want to update #drat.Startdaydiff with Select DATEDIFF(SS,' 08:00:00.000',' 08:15:00.000') If #draft.endday < 16:00:00.000 then update #draft.enddaydiff with the differenceĪnd this is DDL of both of the tables being used Create Table #draft If #draft.startday > 08:00:00.000 then update #draft.startdaydiff with the difference If #draft.startday is > #SI.startday then update #draft.startdaydiff with the difference I need to verify that the following criteria is met with date/time fields in my table.

I have a situation where I am not certain how to make the desired update.
