Table consists of:
Area|Date|Employee|Qty where Area|date|employee are the key
On "Sunday" someone will complete these for Monday. The probability is that the key fields will remain constant for the next 4 days.
Is it possible that is could filter the key fields where Date = "today", and then copy the records * 4 each time incrementating the date?
I have thought about copying "Today" out to a temp table, dateadd + 1 and then inserting these back into the table. I guess i need to loop, but as am i newbie, a point in the right direction would be appreciated.
I can run these as storedprocedure overnight so when they arrive on Tue, the entries are already in.
Thanks 🙂

I seriously doubt you need a loop for this. Take a look at the first link in my signature for best practices on posting questions. After you post ddl, sample data and desired result we can knock this out pretty easily.

It's easy...

INSERT INTO yourtable

(Area, Date, Employee)

SELECT Area, Date = DATEADD(dd.t.N,Date), Employee

FROM yourtable yt

CROSS JOIN (SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4) t (N)

WHERE yt.DATE = DATEDIFF(dd,0,GETDATE())

;

This is the code which i am using, but i am getting incorrect syntax near 4 which is on the cross join line...

INSERT INTO mytable

([Area],[Employee No_],[Date]

SELECT

[Area],[Employee No_],[Date]= DATEADD (dd,4,[Date])

FROM mytable

CROSS JOIN (SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4)[Date] (4)

WHERE [DATE] = DATEDIFF(dd,0,GETDATE())

in your example, what does t mean?

I have managed to solve the syntax error, by doing:

CROSS JOIN (SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4) as T (N)

and i do now have the additional lines - however these all have the same date.

what should be happening is

today = 30/04/2012

so the additional lines should be

01/05/2012

02/05/2012

etc

Again if you want detailed help you need to provide ddl, sample data and desired output. This is pretty straight forward code but without something to work we are shooting in the dark. We can get close sometimes like Jeff did above, but not exact.

Try this

INSERT INTO mytable

([Area],[Employee No_],[Date]

SELECT

[Area],[Employee No_],[Date]= DATEADD (dd,N,[Date]) -- Replace the hard coded 4 with "N"

FROM mytable

CROSS JOIN (SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4) AS T (N)

WHERE [DATE] = DATEDIFF(dd,0,GETDATE())

t is the alias for the derived table. You'll need that to name the table and you'll also need to put it back in the dateadd calc.

The code I wrote for you worked just fine. Why are you trying to rewrite it?

Actually, there's a typo in the original which probably threw him off.

DATEADD(dd.t.N,Date)

Thanks all. Changing the 4 backup N sorted it.

The reason I rewrote was due to getting syntax so I tried to resolve before asking.

I didn't post the original table set up etc was the first solution was exactly what I was after, only I needed help in doing the slight tweak.

Again thanks for your help, and I will be back !
