When I am receiving a batch of message from a queue to process, does it matter if I order by the queuing_order or the message_sequence_number? I want to make sure my messages process in the order in which they were put into the queue, which I know will happen if I process messages one-by-one, but want to make sure that the data I pull and process execute in the order in which they were received.

Hi -
In my application, I need to be able to guarantee that processing for a re-used conversation is completed prior to starting processing the next (re-used) conversation. My application is based on the concepts from the sample posted on Remus's blog: http://blogs.msdn.com/remusrusanu/archive/2007/05/02/recycling-conversations.aspx#comments). Essentially (in this sample), we create a new conversation for each SPID and re-use the conversation, so that messages are sent through the queue (and processed in order) for each SPID. SPID was used in the sample code as an example of some application-specific "thing" that you care about message ordering for. To prevent a conversation from living forever (using up log/resources), they are ended after 1 hour using DialogTimer and a customer message type.
My conundrum is this:
Assume conversation 1 (on SPID 1) is flooded with a large number of messages just before the conversation timer expires. The DialogTimer then expires before the target queue is drained. The sample code (mentioned above) then creates a new conversation for the same SPID (with a DialogTimer of 1 hour). Until the queue for conversation1 is drained, we have 2 conversations being processed for the same SPID. This same problem would occur in any application where you re-use conversations for a period of time (using DialogTimer), and then start a new conversation when the DialogTimer expires.
So although I like having the idea fof being able to re-use conversations, I would need to guarantee that conversation 1 is finished processing before conversation 2 starts processing (for the same SPID, to be consistent with the sample above). If I could get these 2 conversations into the same conversation group on the target queue, the CG locking would solve the problem. But because conversation groups only apply to the initiator queue (when you begin dialog with related conversation), I have no "out of the box" way to control how the conversation groups are associated on the target queue. Remus posted an idea here (bottom of thread): http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=182646&SiteID=1, which was to just send a special message at the beginning of each new conversation (containing the conversation group to use), and then doing a move conversation to conversationgroupid on the target queue. I've tried this solution, and the problem is 1.) if the set convo message fails for some reason, the conversation group is not set and 2.) if the target queue seems to reject most of my move conversation commands with the error "The destination conversation group '<conversation guid>' is invalid." - which I am guessing is due to the fact that this convo group id is being used on the initiator as well.
Any ideas?
Thanks!

In my SQL Server, I see the below message in the Application Event Viewer
"18265 :
Log backed up: Database: HSD, creation date(time): 2007/01/06(05:05:05), first LSN: 1439:495055:1, last LSN: 1439:496675:1, number of dump devices: 1, device information: (FILE=1, TYPE=DISK: {'D:MSSQLBACKUPHSDHSD_tlog_200707141300.TRN'})."
When I save the application event viewer and open it in another server, I do not see the above message, instead I get the following message:
" Can't find or load message DLL. Message DLL must be in path or in current directory."
Any thoughts to overcome this problem is appreciated.

I run SB between 2 SQL servers. In profiler on an initiator side I see next error: 'This message could not be delivered because its message timestamp has expired or is invalid'. For the conversation we use best practice, i.e. target closes a conversation. Target side succeed to close conversation, but initiator still stay in DO (disconnect_outbound).
What is a reasone for the error? What to do?
I see in profiler this error: "This message could not be delivered because its message timestamp has expired or is invalid"

Hi there!
We are experiencing a problem using order clause in the statement below:
SELECT
person.pkey
, first_name
FROM
person
, private_person
WHERE
fkey_person = person.pkey
AND first_name = 'A'
ORDER BY
first_name
, person.pkey
Where person table contains the following columns:
pkey, name etc
and private_person
pkey, fkey_person (indexed), first_name (indexed)
The output is:
STEP 1
The type of query is SELECT
FROM TABLE
private_person
Nested iteration
Index : i$private_person$first_name
FROM TABLE
person
Nested iteration
Using Clustered Index
pkey first_name
----------- ---------------------
2000512 A

2299 A
1097 A

5133 A
1329 A
1387 A
1465 A
7532 A
5513 A
1884 A
512 A
591 A
(14 row(s) affected)
STEP 1
The type of query is SETOFF
Why SQL server does not order by pkey? Is there any information about it somewhere? Is it a bug or what?
If we are ordering by fkey_person everything is Ok. Can anybody help?
Thanks a lot!

I have an int field - that will hold number for an ordering system. It's a databound field to a textbox in a grid, I want the default to be empty, however not all fields are required so i may have 1-6 as bound values, and the rest should fall in line behind them - the only thing i can think of to do is default the values to 9999 so they come after 1,2,3,4,5,6 etc... I don't like seeing 9999 in my bound fields.
thanks for any suggestions you may have.

Hello.
I want to order a resultset from a table by two columns in another table. Here's how it looks:
[Books]
ID
Title
[linkBookAuthor]
BookID (Books.ID)
AuthorID (Authors.ID)
[Authors]
ID
Firstname
Lastname
AuthorOrder
As you can see it's a many to many relationship. Is there a way to order the books by Authors.Lastname (the first if there are several authors) with one query ? If not, what is the fastest way ? I don't need the names in the resultset so I only want to order the books by Authors.Lastname, not include Authors.Lastname.
Thanks for any help.
Hiya!
I've got a little stored procedure:
CREATE PROCEDURE rICDCode @param1 char(15) = 'Description'
AS
SELECT DiagCode, ICD9ID, Description
FROM ICDCodes
ORDER BY @param1
and SQL is returning error 1008 - "The SELECT item identified by the ORDER BY number %d contains a variable as part of the expression identifying a column position. Variables are only allowed when ordering by an expression referencing a column name."
I want to be able to use the same stored procedure for several different functions which all need the same rowset sorted differently. Any way to do this?
Thanks,

Hi guys.
I want to create a top 20 product list from a few thousand products. I want the rest of the products to be grouped into 'others'...
I also want the products to be ordered by the facts in the cube. Thus the product dimension would dynamically change depending on the Time dimension thats being selected.
is this plausible ?
Thanks

Is it possible without using CASE statements, to order a result set by one field (if the second field return value is null) or another (if the second field return value is not null)
This would be on datetime fields.
Let's say I have 5 records with 2 date fields
sched_dt and arriv_dt.
sched_dt will always have a value, arriv_dt may or may not have a value.
In a single result set I would like to have the records with an arriv_dt sorted by arriv_dt and the ones without an arriv_dt sorted by sched_dt.
*Hope that makes sense*
Thanks
I have a table that has 4 dates for each record (birthday, anniversary, policy_start & policy_end). What I want to do is cycle through each record and then do some calculations using the gaps between the dates. So it
might be Calc1 using (birthday->anniversary), Calc2(anniverary->policy_start), Calc3(policy_start->policy_end), etc. BUT the dates might be in different orders (ie the birthday could come first - or the anniverary could, etc).
In VBA in Excel, I can use the SMALL function within my calcs and this returns the minimum date, the next smallest, the next & then the biggest. But how can I do this in SQL. I guess I can push the 4 dates out to a temp table, order it and then suck them back in - but I have no idea how to do this for all the records in my primary table
I've also tried using various WHERE statements (ie do Calc1 using Birthday & Anniversary WHERE Birthday < Anniversary and ........ - but the code gets awfully long.
Is it possible to write my own SMALL function which uses a bubble sort on the 4 dates & then returns the smallest, next smallest, etc
Any thoughts ?
Hi all,
Ive got a table with a field called 'morder' which orders a menu based on the values in this field (1 for position 1, 2 for position 2 etc...) for example
1 - menu item 1
2 - menu item 2
3 - menu item 3
4 - menu item 4
If I want to add a record to this table and put it at number 2 in the list, i need to update the table to then read...
1 - menu item 1
2 - NEW menu item 2
3 - menu item 2
4 - menu item 3
5 - menu item 4
I want to use a mssql or php function to re-order this field... is it possible??
Hope you can help, and hope it makes sense...

Hi, I was wondering, I have several columns of data that are able to be sorted on - the user just clicks on the column name. However, we have 1 column called order status where we don't want the order to be alphabetical (and it is a text field - a couple current possible values are Processing...In Production...Waiting For Approval). This order is not good for logical sorting - we would want to be able to specify what value would get order. Does that make sense? So we would want to be able to say that Processing is first in the display, Waiting For Approval would be next, then In Production would be next, and so on. Is there any possible way of doing this in a SQL query? Or am I going to have to manually modify all the data adding numbers to the beginning of each data so that it will sort on the numbers? Thanks everyone.

Hi,I'm streaming data monitoring histories of components into a database table with the following three columns: Hour (DateTime), Id (Int64), and Value (Int32). The Value entry is an aggregate of all values sent from component Id during, and 59 minutes and 59 seconds after, the time listed in the Hour column.I had rather not have to sort the queries after pulling them from the database by date. So I tried to index the DB by the Hour column. Any column will inevitably have duplicates, since the uniqueness depends on a combination of Hour and PortId. But Indexing the Hour column doesn't result in INSERTs being in order as I had expected. Instead, every entry is listed in order of insertion.So. . .how can I keep such a table ordered by date on the disk? I'm afraid this will become very inefficient if this isn't nipped in the bud right now.Thanks so much for your help!-Brandon

Hi all,
Ive got a bit of a problem,
I have two tables:
CATEGORY
id
name
parent_CATEGORY_id
RECORD
id
CATEGORY_id
Stock_Held_Number
ps. Ive stripped out any non relevant fields
I also have the following query (again ive stripped out the non-relevant fields)
SELECT TOP (100) PERCENT SUM(dbo.RECORD.Stock_Held_Number) AS TotalStock, CATEGORY.Name AS FundName
FROM CATEGORY
LEFT OUTER JOIN dbo.RECORD ON CATEGORY.ID = dbo.RECORD.CATEGORY_id
GROUP BY CATEGORY.Name, RECORD.Stock_Held_Number
At the moment its grouping all the CATEGORIES and giving me a sum total for each which is great.
The problem I have is the CATEGORY table, there is an optional join to parent CATEGORY records on the table.
What Im trying to do is to provide a fully ordered result within the CATEGORIES and I don't have a clue.
For example:
The CATEGORY table has the following values
ID Name Parent_Category_id
1 Pens
2 Animals
3 Rocks
4 Horses 2
5 Dogs 2
When I currently run the query I get:
Name TotalStock
Pens 20
Animals 30
Rocks 40
Horses 50
Dogs 60
It's technically correct because I don't want the parent to calculate the total value of the children
What Im really trying to do is order them within the hierarchy though and indent (if possible) the result so I would get
Name TotalStock
Animals 30
---Dogs 60
---Horses 50
Pens 20
Rocks 40
Does anybody have any pointers as to how I can achieve this.
Many thanks
Mike

Hello,
I'm attempting to run three separate queries and have them returned as one recordset. I need to show the top 10 customers based on the number of orders they placed for each of three months, then combine them to give a representation of which customers have been within the monthly top 10 for the overall period of three months. My problem is when I run a count on the number of orders they have placed and order by that count, it is in ascending order which in escence shows me the bottom 10, not the top 10. To resolve this issue, I can specify descending order. This works fine with one query, but when I run all three queries using union statements, I can only have one order by which returns incorrect results. Here is my query. In this example, I get the combination of the three recordsets as expected, but each of the individual queries is not ordering descending, so I get the wrong end of the table. I am not bound to union, but do not know where to go. I do not believe I can use joins or concatenate queries because I have multiple where clauses. Any help would be greatly appreciated.
Please note that I am using a view to convert the cryptic field names which are used by a third party software tool into more friendly names. We will call this view Friendly_View for this example.
USE MyDB
SELECT TOP 10 CustName, Location, Phone, COUNT(Orders) AS TotalOrders

WHERE MONTH([Order Date]) = MONTH(GETDATE())-1 AND YEAR([Order Date]) = YEAR(GETDATE())

hi, i'm using a similar code for a recursive relationship in sql server
written @
http://www.eggheadcafe.com/articles/sql_server_recursion_with_clause.asp.i'm using the Table of Contents Hierarchy code in the article.
However, instead of ordering by the sort order, i'm using the TOC
instead. My problem is, i know TOC is of varchar type, therefore, if
the sort order has an integer of more than 10, the order sequence would
be 1.01.11.101.111.2etc.so how do i make it so that it is1.01.11.21.3......1.10 instead? Thank you
