Hi,
I have 3 tables : Products, Orders and OrderDetails.
The Products table has a ProductCode field
The Orders table has an AccountNumber, DeliveryDate field and an ID field
The OrderDetails has a foreign key that points to the ID field in Orders
The OrderDetails has a foreign key that points to the ProductCode in Products
I need to get a list of all ProductCodes
For each ProductCode I need to get the most recent Orders.DeliveryDate and OrderDetails.Quantity where Order.AccountNumber equals a given AccountNumber
For example assume each table contains the following records:
Products Table
ProductCode
A1
B2
C3
D4
E5
OrderDetails Table
ID ProductCode Quantity
1 A1 1
1 B2 2
1 D4 4
2 C3 1
2 E5 2
Orders Table
ID AccountNumber DeliveryDate
1 1234 03/07/2008
2 6789 26/06/2008
Assume I want information for AccountNumber 1234. The results I need are as follows:
ProductCode DeliveryDate Quantity
A1 03/07/2008 1
B2 03/07/2008 2
C3 NULL NULL
D4 03/07/2008 4
E5 NULL NULL
Assume I want information for AccountNumber 6789. The results I need are as follows:
ProductCode DeliveryDate Quantity
A1 NULL NULL
B2 NULL NULL
C3 26/06/2008 1
D4 NULL NULL
E5 26/06/2008 2
I know that I could get a datatable with a list of products and then write some code to loop through it and lookup Orders and OrderDetails to get the other two fields but I'd rather get all the information that I need in one call.
Any ideas how to go about writing the SQL Select statement?
Thanks,

Have you tried one? Try a query and if it doesn't work, ask for help.

First result for accountnumber 1234
SELECT OD.ProductCode, O.DeliveryDate, CASE WHEN O.DeliveryDate IS NULL THEN NULL ELSE OD.Quantity END AS quantity<br />
FROM dbo.Products P INNER JOIN<br />
dbo.OrderDetails OD ON P.ProductCode = OD.ProductCode LEFT OUTER JOIN<br />
dbo.Orders O ON OD.ID = O.ID AND O.AccountNumber = 1234
Second result for accountnumber 6789
<br />
SELECT OD.ProductCode, O.DeliveryDate, CASE WHEN O.DeliveryDate IS NULL THEN NULL ELSE OD.Quantity END AS quantity<br />
FROM dbo.Products P INNER JOIN<br />
dbo.OrderDetails OD ON P.ProductCode = OD.ProductCode LEFT OUTER JOIN<br />
dbo.Orders O ON OD.ID = O.ID AND O.AccountNumber = 6789

Hi to all,
Hope I'm posting this in the right discussion group.
I wonder if anyone can tell me if VS 2008 brought in support for rich text formatting or HTML in reports of Reporting Services?
I did see some reports on the possibility but would like to know for sure.
Hope you can help.
Kind regards

i have a column its values must started with 1 and incrementing by 1
this column repeatly looses his rows
so i can not use identity here
so i tried to raise a trigger to do the job
but i have some probelems with the following statments
create trigger dbo.insertNum
on testIcreTrigger --table name
for insert
AS
begin
declare @insVal int --value to insert
declare @MaxVal int
select @MaxVal= Max(Num) from hitTheatre
select @insVal=@MaxVal+1
insert into testIcreTrigger (Num)
values (@insVal)
End
Go
|
|
|
|
|
Have you tried
SET @MaxVal= (select Max(Num) from hitTheatre)
SET @insVal= (@MaxVal+1)
Just guessing..
|
|
|
|
|
Another solution is to run DBCC CHECKIDENT('[table name]', RESEED, 0) when you flush the table and just use an identity.
|
|
|
|
|
You should replace *for insert* with *INSTEAD OF INSERT*.
When FOR is the only keyword specified, AFTER is used by default.
CREATE TRIGGER dbo.insertNum
ON testIcreTrigger
INSTEAD OF INSERT
AS
BEGIN
INSERT INTO testIcreTrigger (Num)
SELECT MAX(Num)+1 FROM hitTheatre
END

Hi,
I am not sure whether SQLServer 2000 and SQLServer 2005 can be installed in same folder. But they can be installed on same machine in different folders. However, you can not have two default instances of any version of SQL Server but you can have ten different installations of SQLServer 2000 and SQLServer 2005 as long as they are all named differently, they can co-exist with out an issue.
Hope this helps.

I am going to assume you are trying to create a key field for your employee, if so then:
DO NOT ADD INTELLIGENCE TO A PRIMARY ID/KEY FIELD, you are doing this by adding the first character of the surname. This is wrong, it should simply be the record identifier, use the surname field for search/sorting NOT the ID field.
Generating an employee number for human consumption (timecards or something) is a different matter. I would put it in the inserting stored procedure (I never use triggers)
Before the insert get the count of existing surnames with the 1st char
Select @N = (count(*) + 1) From Employee where Surname like 'A%' (this fails when the employee changes surnames - gets married and is the reason for the initial comment)
or
Select top 1 employee where ENO like 'A%'
order by ENO desc
Add the text to the ENO field

Hi,
I need to creat a trigger on 'myTable' after 'insert' new records...I need to send an email every 30 minutes if Insert happenned...Any one plz can help???
I searched over the Internet, but nothing is useful for this purpose.
And in the future, my goal is to send this email depending on the time specified by the user after Insert.
Kind Regards

This is not a "trigger" or an procedure operation. You would need to create and schedule a job in SQL Server to acheive this. It would have to poll the target table to identify the records inserted say every 2 minutes and if there are records then execute the mailing stored proc.
