In-Order/Level Order Etc. Traversal Using CTE
Apr 16, 2008
Hi,
I have some hierarchical data in a table. Say for example:
Parent Child
------------------------
NULL 1
1 2
1 3
2 4
2 5
3 6
3 7
5 8
5 9
7 10
7 11
11 12
11 13
Now I want to be able to use CTE's to be able to traverse this tree in
1) level by level order 1,2,3,4,5,6,7,8,9,10....
2) in order 1,2,4,5,8,9,3,6,7,10,11,12,13...
What would be the aueries for this. Using the following i get: 1,2,3,6,7,10,11,12,13,4,5,8,9 (interesting and potentially useful) but I would like to be able to experiment with the aforementioned orders as well.
with Tree (id)
as
(
select id from WithTest
where parent is null
union all
select a.id
from Tree b join WithTest a
on b.id = a.parent
)
select * from Tree
Any ideas? Thanks.

Finding the "pieces of information" I need to successfully install the SQL Server Express edition is so complex. Uninstalls do "not" really uninstall completely, leading to failure of SQL install. Can you suggest a thorough, one-stop site for directions for the order of app uninstalls and then the order for app installs for the following...
SQL Server Express edition
Visual Studios 2005
Jet 4.0 newest upgrade
.Net Framework 2.0 (or should I use 3.0)
VS2005 Security upgrade
Anything else I need for just creating a database for my VS2005 Visual Basic project?
I was trying to use MS Access as my backend db but would like to try SQL Express
Thank you, Mark

In SQL sERVER 2008, I have two fields - Depatment and Employees. I need to sort the result set by employee number ascending order, with following exception
1)when department number = 50 - the preferred order is Employee # - 573 followed by 551-572 (employee # belong to Dept 50 = 551-573)
2)When Department number = 20 – the preferred sort order is Employee # 213-220, followed by Employee # 201-213 (employee # belong to Dept 20 = 201-220)
How shall I achieve this?

I never paid much attention to this before but I noticed this today in a new table I was creating.
For tables defined in the tabular model the table properties have something like SELECT Blah FROM TableName ORDER BY Blah Then in the tabular model the table's data is in the same order it was ordered by in the data source for the table.
I have a date table I setup and I noticed it is NOT respecting the sort order.
I have it sorted by DateID which sorts with the oldest date first and newest date as last row.However, the table that is imported and stored in the data model is not in that order.
I can of course manually sort the rows in BIDS/DataTools, but I find this discrepancy odd.
Would this have negative impacts on the EARLIER function for example if the data rows are not in the order specified?

I have a query that calculate the total amount of order details based on a particular order:
Select a.OrderID,SUM(UnitPrice*Quantity-Discount)
From [Order Details]
Inner Join Orders a
On a.OrderID=[Order Details].OrderID
Group by a.OrderID
My question is what if I wanted to create a formula to something like:
UnitPrice * Quantity - DiscountAmount Where DiscountAmount = UnitPrice Quantity * Discount
Do I need to create a function for that? Also is it possible to have m y query as a table variable?

Hi!
I recently run into a senario when a procedure quiered a table without a order by clause. Luckily it retrived data in the prefered order.
The table returns the data in the same order in SQL Manager "Open Table"
So I started to wonder what deterimins the sort order when there is no order by clause ?
I researched this for a bit but found no straight answers. My table has no PK, but an identiy column.
Peace.

Hi,
We got a problem.
supposing we have a table like this:
CREATE TABLE a (
aId int IDENTITY(1,1) NOT NULL,
aName string2 NOT NULL
)
go
ALTER TABLE a ADD
CONSTRAINT PK_a PRIMARY KEY CLUSTERED (aId)
go
insert into a values ('bank of abcde');
insert into a values ('bank of abcde');
...
... (20 times)
select top 5 * from a order by aName
Result is:
6Bank of abcde
5Bank of abcde
4Bank of abcde
3Bank of abcde
2Bank of abcde
select top 10 * from a order by aName
Result is:
11Bank of abcde
10Bank of abcde
9Bank of abcde
8Bank of abcde
7Bank of abcde
6Bank of abcde
5Bank of abcde
4Bank of abcde
3Bank of abcde
2Bank of abcde
According to this result, user see the first 5 records with id 6, 5, 4, 3, 2 in page 1, but when he tries to view page 2, he still see the records with id 6, 5, 4, 3, 2. This is not correct for users. :eek:
Of course we can add order by aid also, but there are tons of sqls like this, we can't update our application in one shot.
So I ask for your advice here, is there any settings can tell the db use default sort order when the order by column value are the same? Or is there any other solution to resolve this problem in one shot?

I have created view by jaoining two table and have order by clause.
The sql generated is as follows
SELECT TOP (100) PERCENT dbo.UWYearDetail.*, dbo.UWYearGroup.*
FROM dbo.UWYearDetail INNER JOIN
dbo.UWYearGroup ON dbo.UWYearDetail.UWYearGroupId = dbo.UWYearGroup.UWYearGroupId
ORDER BY dbo.UWYearDetail.PlanVersionId, dbo.UWYearGroup.UWFinancialPlanSegmentId, dbo.UWYearGroup.UWYear, dbo.UWYearGroup.MandDFlag,
dbo.UWYearGroup.EarningsMethod, dbo.UWYearGroup.EffectiveMonth
If I run sql the results are displayed in proper order but the view only order by first item in order by clause.
Has somebody experience same thing? How to fix this issue?

I am getting the resultset sorted differently if I use a column number in the ORDER BY clause instead of a column name.
Product: Microsoft SQL Server Express Edition
Version: 9.00.1399.06
Server Collation: SQL_Latin1_General_CP1_CI_AS
for example,
create table test_sort
( description varchar(75) );
insert into test_sort values('Non-A');
insert into test_sort values('Non-O');
insert into test_sort values('Noni');
insert into test_sort values('Nons');
then execute the following selects:
select
*
from
test_sort
order by
cast( 1 as nvarchar(75));
select
*
from
test_sort
order by
cast( description as nvarchar(75));
Resultset1
----------
Non-A
Non-O
Noni
Nons
Resultset2
----------
Non-A
Noni
Non-O
Nons
Any ideas?

I noticed the StockDate is not sorted in proper order, like ascending order...
Code:
select top 1000 CONVERT(char, StockDate, 101) AS StockDate, timestamp from tblpurchaseraw where accountid = '119' order by stockdate desc
I noticed that StockDate is a datetime datatype so why does the month get ordered 1st, then day get ordered 2nd and year get ordered 3rd...
The sample data is MM/DD/YYYY...
So, how do I get it ordered propery by Year, Month then Day??

Lets say I have a table named [Leadership] and I want to select the field 'leadershipName' from the [Leadership] Table.
My query would look something like this:
Select leadershipName
From Leadership
Now, I would like to order the results of this query... but I don't want to simply order them by ASC or DESC. Instead, I need to order them as follows:
Executive Board Members, Delegates, Grievance Chairs, and Negotiators
My question: Can this be done through MS SQL or do I need to add a field to my [Leadership] table named 'leadershipImportance' or something as an integer to denote the level of importance of the position so that I can order on that value ASC or DESC?
Thanks,
Zoop

Hi!
For the Orders table (let's assume for the Northwind database), I'm trying
to get the order id of the latest order for every customer.
That means that the result should be one record per customer and that would
display CustomerID and OrderID.
Any ideas?
Thanks,

The data file is a simple Unicode file with lines of text. BCPapparently doesn't guarantee this ordering, and neither does theimport tool. I want to be able to load the data either sequentially oradd line numbering to large Unicode file (1 million lines).

Hello
I am not sure of the correct syntax.
I know that the first part works:
******************************
SELECT Extn, Domain_Name, Price
FROM Domains_DB
****************************
I am trying to add a WHERE clause is equal to com and an ORDER BY assending order.
I have tried all sort of combinations, where am I going wrong with the following:
SELECT Extn, Domain_Name, Price
FROM Domains_DB
[WHERE Extn = com [ORDER BY Domain_Name ASC ]]
Thanks.

I need to BCP out from a table and guarantee the "ORDER BY" with a key column.
When using BCP, are the records guaranteed to be returned in a specific order?
If not, how can I specify?
(BOL says selecting without an ORDER BY clause cannot guarantee order of result set.)

In a stored procedure MS-SQL I am trying to write an order by expression that is a function of the incoming paramters.
SO for example
CREATE PROCEDURE test
@sortby varchar(10)
AS
SELECT * FROM table WHERE condition
ORDER BY @SORTBY
Gives an error (1008) but the error message implies that you can use a variable in the order by expression.
I have tried every combination I can think of
with the variable as varchar = column name, as integer .
I have also tried variations of
Order by COL_Name(OBJECT_ID('item"), variable) and I ether get errors or no errors but no order either.
Any leads appreciated.
