Hi folks,
I have a database table named ProcessTest1. I would like to get the deadline dates of business processes. This table contains parametric values of the sequential business processes.The table structure is like below:
CREATE TABLE [dbo].[ProcessTest1](
[ProcessID] [char](4) ,
[ProcessName] [char](50) ,
[FabricType] [char](1) ,
[ProductType] [int] NULL,
[ProductStyle] [char](1) ,
[StockType] [int] NULL,
[ProductLine] [char](1) ,
[DayCount] [int] NULL,
[OverlappedTo] [char](4) ,
[OverlapDayCount] [int] NULL,
[ProcessAfter] [char](4)
) ON [PRIMARY]
------------
--------------------------------------
My sample data is like below:
INSERT INTO ProcessTest1 VALUES ('001','Process1','D',1,'T',2,'W',12,NULL,NULL,NULL)
INSERT INTO ProcessTest1 VALUES ('002','Process2','D',1,'T',2,'W',1,'001',1,'001')
INSERT INTO ProcessTest1 VALUES ('003','Process3','D',1,'T',2,'W',2,'001',2,'002')
INSERT INTO ProcessTest1 VALUES ('004','Process4','D',1,'T',2,'W',2,'001',2,'003')
INSERT INTO ProcessTest1 VALUES ('005','Process5','D',1,'T',2,'W',4,NULL,NULL,'001')
INSERT INTO ProcessTest1 VALUES ('006','Process6','D',1,'T',2,'W',4,NULL,NULL,'005')
-----------
Expected Result is:
'001', '21.06.2008' (Root Process)
'002','10.06.2008' (OverlappedTo root process)
'003','12.06.2008' (OverlappedTo root process and Sequential to previous process '002')
'004','14.06.2008' (OverlappedTo root process and Sequential to previous process '003')
'005','25.06.2008' (Sequential to previous process '001')
'006','29.06.2008' (sequential to previous process '005')
If I enter the current date and then how can I get the final deadline time by using this database table?
I mean, I would like to get a new resultset that contains 2 columns such as:
ProcessID and DeadLine
Please help..

Where are you entering the Current date and also there is no deadLine COlumn in this table.

Are you trying to calculate the DeadLine based on the Given Current Date using some calculations. Can you give some Samole Datas and Expected Results

I should enter getdate() (or another date value) as an input parameter. The sub-process final dates will vary based on this input parameter.And there should be a recursion in this query.Right?

I see that now.

I responded to a PM and saw that OP posted same question on the forums.

Didn't notice the version.

Oh god!!!!!

Where were you :):):)

Well, viewer count exceeded 700 🙂

Thank you very much for your replies (also thanks to all readers..:) ).If it possible I would like to ask another question based on this query.

How can I use a date parameter instead of GetDate() ?

Thanks for the feedback, Peter... Op seems happy with the excellent 2k5 solution. Too bad... was putting the final touches on the 2k solution but I'll quit now. I, too, was responding to a PM... guess I won't respond to those types of PM's anymore.

It works like a ferrari... 🙂

Now I will try to extend this procedure by using "business days=working days" of a week..Is it possible to use working days of a week?

THANK YOU VERY MUCH......

I just clicked OP's "all post" to see if I didn't invent the wheel again.

If I hadn't, both you and me would present a working solution. What a waste of time.
