How To Handle Scoring In Search Feature?
Feb 15, 2007
Good day all,
I'm looking for suggestions on how to handle the calculating of scores for search results from data. Primarily if it would be best to calculating the score on the SQL server side or in the application's logic itself after the results have been retrieved? I already have an idea of the calculations I want to do which will be pretty simple, just a basic point system for containing all the queried terms and additional points for the number of times those words appear on the page.
Feedback or links to articles on this would be appreciated. I'm leaning towards doing so on the SQL side myself but my SQL skills are not as polished as I would like for jumping into that, so examples could be good.

Hi!We have Sql Server 2000 in our server (NT 4). Our database have now about+350.000 rows with information of images. Table have lot of columnsincluding information about image name, keywords, location, price, colormode etc. So our database don?t include the images itself, just a path tothe location of every image. Keywords -field have data for example likethis:cat,animal,pet,home,child with pet,child. Now our search use Full-TextSearch which sounded like good idea in the beginning but now it have hadproblems that really reduce our search engine?s performance. Also searchresults are not exact enough. Some of our images have also photographer?sname in keywords -column and if photographer?s name is, for example, PeterMoss, his pictures appears in web-page when customer want to search "moss"(nature-like) -pictures.Another problem is that Full-Text Search started to be very slow when queryresult contains thousands of rows. When search term gives maximum 3000rows, search is fast but larger searches take from 6 to 20 seconds tofinish which is not good. I have noticed also that first search is alwaysvery slow, but next ones are faster. It seems that engine is just"starting" when first query started to run.Is there better and faster way to handle the queries? Is it better torebuild the database somehow and use another method to search than Full-Text Search? I don?t know how to handle the database other way when everyimage have about 10 to even 50 different keywords to search.We have made web interface and search code with Coldfusion. ColdfusionServer then take care of sending all queries to Sql Server.I hope that somebody have some idea how to speed up our picture search.--Message posted via http://www.sqlmonster.com

I am currently faced with developing a search function (ASP.NET 1.1
based user interface) to a database (SQL Server 2000 ), and I am
wondering how best to handle the logistics of it.
The search can take anywhere from one to 9 parameters. The search would be executed against three related tables.
The main problem, as I see it at this stage, is how to handle
parameters that have not been selected, it's easy enough to do a search
with all 9 parameters, but as soon as there is an unpredictable
variable number of search criteria, I just don't know how best to
handle this in a stored procedure for example.
I would be very grateful for some guidance.
Thanks.

I have a scoring query already. However, I need to count how many cases belong to each score. I was not sure how would I write a statement for that. Please see example below:
Column Name: 10 columns (Score1, Score2, Score3, Score4, Score6, Score5, Score6, Score7, Score8, Score9, Score10 and TotalScore)
Each column was range from score 10 to 100, such as:
1) Score1:
case when score1 is null then 0
when score1 >10000000 then 100
when score1 > 1000000 then 90
when score1 > 100000 then 75
when score1 > 10000 then 50
when score1 > 1000 then 25
when score1 > 0 then 10
else 0 end as Score1
Same thing for other score columns.
I already wrote case statement for 10 scored columns, and totalscore = (score1 + score2 + ...score10. But now I need to count how many cases in the below range:
1. How many cases > 199?
2. How many cases from 150 to 199
3. How many cases from 100 to 149
4. How many cases from 50 to 99
5. How many cases from 25 to 49
6. How many cases from 1 to 24
7. and how many cases <1
Can anyone help me to write this statement? Thank you very much!

Hi
I'm using service broker and keep getting errors in the log even though everythig is working as expected
SQL Server 2005
Two databases
Two end points - 1 in each database
Two stored procedures:
SP1 is activated when a message enters the sending queue. it insert a new row in a table
SP2 is activated when a response is sent from the receiving queue. it cleans up the sending queue.
I have a table with an update trigger
In that trigger, if the updted row meets a certain condition a dialogue is created and a message is sent to the sending queue.
I know that SP1 and SP2 are behaving properly because i get the expected result.
Sp1 is inserteding the expected data in the table
SP2 is cleaning up the sending queue.
In the Sql Server log however i'm getting errors on both of the stored procs.
error #1
The activated proc <SP 1 Name> running on queue Applications.dbo.ffreceiverQueue output the following: 'The conversation handle is missing. Specify a conversation handle.'
error #2
The activated proc <SP 2 Name> running on queue ADAPT_APP.dbo.ffsenderQueue output the following: 'The conversation handle is missing. Specify a conversation handle.'
I would appreceiate anybody's help into why i'm getting this. have i set up the stored procs in correctly?
i can provide code of the stored procs if that helps.
thanks.

I'm just wonder if this is a bug in MS Search or am I doing something wrong.
I have a query below
declare @search_clause varchar(255)
set @Search_Clause = ' "hepatitis b" and "hepatocellular carcinoma"'
select * from results
where contains(finding,@search_clause)
I don't get the correct result at all.
If I change my search_clause to "hepatitis" and "hepatocellular carcinoma -- without the "b"
then i get the correct result.
It seems MS Search doesn't like the phrase contain one letter or some sort or is it a know bug?
Anyone know?
Thanks

We have implemented our service broker architecture using conversation handle reuse per MS/Remus's recommendations. We have all of the sudden started receiving the conversation handle not found errors in the sql log every hour or so (which makes perfect sense considering the dialog timer is set for 1 hour). My question is...is this expected behavior when you have employed conversation recycling? Should you expect to see these messages pop up every hour, but the logic in the queuing proc says to retry after deleting from your conversation handle table so the messages is enqueued as expected?
Second question...i think i know why we were not receiving these errors before and wanted to confirm this theory as well. In the queuing proc I was not initializing the variable @Counter to 0 so when it came down to the retry logic it could not add 1 to null so was never entering that part of the code...I am guessing with this set up it would actually output the error to the application calling the queueing proc and NOT into the SQL error logs...is this a correct assumption?
I have attached an example of one of the queuing procs below:
Code Block
DECLARE @conversationHandle UNIQUEIDENTIFIER,
@err int,
@counter int,
@DialogTimeOut int,
@Message nvarchar(max),
@SendType int,
@ConversationID uniqueidentifier
select @Counter = 0 -- THIS PART VERY IMPORTANT LOL :)
select @DialogTimeOut = Value
from dbo.tConfiguration with (nolock)
where keyvalue = 'ConversationEndpoints' and subvalue = 'DeleteAfterSec'
WHILE (1=1)
BEGIN
-- Lookup the current SPIDs handle
SELECT @conversationHandle = [handle] FROM tConversationSPID with (nolock)
WHERE spid = @@SPID and messagetype = 'TestQueueMsg';
IF @conversationHandle IS NULL
BEGIN
BEGIN DIALOG CONVERSATION @conversationHandle
FROM SERVICE [InitiatorQueue_SER]
TO SERVICE 'ReceiveTestQueue_SER'
ON CONTRACT [TestQueueMsg_CON]
WITH ENCRYPTION = OFF;
BEGIN CONVERSATION TIMER ( @conversationHandle )
TIMEOUT = @DialogTimeOut
-- insert the conversation in the association table
INSERT INTO tConversationSPID
([spid], MessageType,[handle])
VALUES
(@@SPID, 'TestQueueMsg', @conversationHandle);
SEND ON CONVERSATION @conversationHandle
MESSAGE TYPE [TestQueueMsg] (@Message)
END
ELSE IF @conversationHandle IS NOT NULL
BEGIN
SEND ON CONVERSATION @conversationHandle
MESSAGE TYPE [TestQueueMsg] (@Message)
END
SELECT @err = @@ERROR;
-- if succeeded, exit the loop now
IF (@err = 0)
BREAK;
SELECT @counter = @counter + 1;
IF @counter > 10
BEGIN
-- Refer to http://msdn2.microsoft.com/en-us/library/ms164086.aspx for severity levels
EXEC spLogMessageQueue 20002, 8, 'Failed to SEND on a conversation for more than 10 times. Error %i.'
BREAK;
END
-- We tried on the said conversation, but failed
-- remove the record from the association table, then
-- let the loop try again
DELETE FROM tConversationSPID
WHERE [spid] = @@SPID;
SELECT @conversationHandle = NULL;
END;

Service Broker will let you create two services with the same name (one with contract and another without)
CREATE SERVICE [Order Msg Recieve] AUTHORIZATION [dbo] ON QUEUE [dbo].[Order Return Msg Queue]
CREATE SERVICE [Order Msg Receive] AUTHORIZATION [dbo] ON QUEUE [ODS].[Order Return Msg Queue] ([OrderSubmission])
When you delete the service....
drop service [Order Msg Recieve]
It will only drop the first one. In the BOL there is no syntax for telling it to delete the second one, however you can drop it from SQL Management Studio.
I stumbled over this by accident. Just FYI

When upgrading a database from MSDE to Visual Studio 2005 Express, I've noticed that the system tables in the MSDB database don't get upgraded. For example, the SYSSCHEDULES table doesn't get added. Is this by design or a bug?

Try this in sql server 2005:
select COALESCE(a1, char(254)) as c1 from
(select 'Z' as a1 union select 'Ya' as a1 union select 'Y' as a1 union select 'W' as a1) as b1
group by a1
with rollup order by c1
select COALESCE(a1, char(255)) as c1 from
(select 'Z' as a1 union select 'Ya' as a1 union select 'Y' as a1 union select 'W' as a1) as b1
group by a1
with rollup order by c1
The only difference is that the first one uses 254 and the second one uses 255. The first sorts like this:
WYYaZþ
The second one sorts like this:
WYÿYaZ
Is this expected behavior?

Has anyone noticed that if you created DTS package and try to
change connection properties (i.e. change DSN or redirect
DTS to different server or Database), as soon you click OK
it does not save new password and hence does not work
anymore. In my case to move Database from Development to
Production server I would have to recreate all DTS packages.
Is there any way around it?
Any ideas greatly appreciated.

We desperately require the RetainSameConnection to be set to True on our ADO.NET - ODBC connection manager. Unfortunately RetainSameConnection always defaults back to False when you open the package.
* Is RetainSameConnection supposed to work for the ADO.NET - ODBC combination?
* Is it a bug that it defaults back to false for the ADO.NET - ODBC combination?
Quick responses much appreciated!

I posted this over on, I guess, the other SQL Server forum (msdn.microsoft.com/newsgroups). Sorry if it's a cross post or better answered there.
Does anyone know if the feature packs are included in SP1 or still need to be installed separately.

Hi!
I am having a terrible time with the report feature. First of all, my queries through it do not match my queries thru SQL server 2005 Express Management. When I enter my fields, through the auto query function, it moves them. When I try to put them where I think they belong (by editing the SQL code, my queries get all messed up).
Is there a way to import my SQL query and run it through the report feature?
I am using windows XP Pro
Microsoft Visual Studio 2005 version 8.0.50727.42
Microsoft SQL Server Reporting Services Designers version 9.00.2047.00

Theres a feature in oracle that allows you to modify tables, colums, values and the data from its enterprise console the same way that you can in sql server. In oracle however theres a button called 'show sql' that allows you to see and copy/paste the resulting sql for the changes made via the console.
I would imagine that sql server has a similar option. The reason i ask is that i would like to more fully learn how to do this through the query analyser and get more familiar with sql involved and I would be able to do this if I could see the resulting sql from enterprise manager.
Hope this makes sense.
I did find something in sql server called 'generate sql' but this doesnt update during changes you make automatically.
Thanks

Hi,
While reading (I have come across what seems to be maybe a powerful and useful feature) available in MSAS and thus this related question:
Can someone briefly explain the use of this feature and how it can come in handy.
So far I have skimmed through BOL and it says that "Only parent-child dimensions support this dimension characteristic" i.e. Write-enabled feature.
Thanks.

Has anyone seen this strange behaviour?
I have a package which loads the fact data from Stage into Warehouse database. This packages normally handles early arriving facts. In that package I use lookup to check the dims which exists, and where they don't I populate the dimension and use the surrogate key to load the facts. This works fine.
I had a request to load 7 years worth of historical data. Instead of re-writing the package I took the package which handles early arriving facts and deleted the section which handles early arriving facts. I knew all the dimensions already exists and I don€™t want to hinder the performance when I load millions of rows. During testing I found something very interesting.
If you have configured error path in the lookup component and removed the error path later, the package will NOT fail (won't produce error) even if the lookup can't find matching values.
Correct Behaviour Example 1:
[1] Stage fact table has 2 records, with product code 1 and 2.
[2] Warehouse Product table has only product code 1.
[3] Source - Lookup - Destination in the data flow task. Error port on lookup is not configured.
[4] From source we read 2 records, and the package will fail at lookup as it can't find Product Code 2.
Correct Behaviour Example 2:
[1] Stage fact table has 2 records, with product code 1 and 2.
[2] Warehouse Product table has only product code 1.
[3] Source - Lookup - Destination in the data flow task. Error port on lookup is configured to go to RowCount.
[4] From source we read 2 records, and the package will run successfully. It will put one record into warehouse table and send the invalid record into RowCount.
Incorrect Behaviour Example 3:
[1] Stage fact table has 2 records, with product code 1 and 2.
[2] Warehouse Product table has only product code 1.
[3] Source - Lookup - Destination in the data flow task. Delete the configured error port from lookup.
[4] From source we read 2 records, and the package will run successfully. It will put one record into warehouse table and discard the other.
My understanding if the error port is NOT configured as shown in example 2, it should fail as shown in example 1.
Am I missing a point or is this suppose to be a correct behaviour or is it a bug?
Thanks

I tried SQL mirroring in beta 1 , then it was gone, until SP1.
Now I can not setup mirror, it is fine if it is just hard to setup, but it seems it is full of bug! The mirroring has to be stable, since I am trying to mirror product db, what a diaster if something goes wrong.
I am trying two servers, both has 9.0.3042. First I tried to setup on my home machine, I VPN to my network, After I config security, I see two connection strings:
TCP://sql8.mydomain.netsql2005:5022
TCP://sql5.mydomain.netsql2005:5022
and I click start mirroring, then I got error - Alter failed due to invalid connection string. Hard to figure it out, right?
Then I tried the same thing on a server in the network, this time I get
TCP://sql8.mydomain.net:5022
TCP://sql5.mydomain.net:5022
and it doesn't show that error anymore, I am not sure why the connection should be like the latter format, but in anyway, how come SMO can not make it right?
then I get another error, SQL server doesn't exist or can not access, I search on the Internet, it seems that error could mean anything, include that the mirror db is not in restore mode.
But I did set the mirror db in restore mode and both sql5 and sql8 are under same domain, pysically close.
So what else I can check?
Any suggestion?
thanks

Hi there,
I am trying here to get a situation going which includes both transactions and checkpoints to make sure that when something goes wrong I don't get a) data corruption (hence the transactions and b) I don't have to completely restart my 2hr run (hence the checkpoints). However I ran into something of which i cannot see whether it is intended behaviour or simply a bug.
Here's the deal:
I have a SSIS-package in which I enable checkpoints (CheckpointUsage: IfExists and SaveCheckpoints: True).
I have 2 Dataflows which follow eachother (the first dataflow prepares data for the second dataflow to edit).
Because I want to make sure that my data is secure I put a separate transaction on both the dataflows.
And here my problem arises. If I run my package now and the second dataflow breaks then my checkpoint sends me back to the first dataflow and my initial insert is executed again, which isn't meant to happen (I enabled checkpoints to prevent rerunning items). Somehow my checkpoint does not register the fact that the first dataflow has already been executed and it will execute that one again upon rerun.
However: if I put a random task between the 2 transacted dataflows (for example an empty script-task) it will work as intended. Just as long as this inserted item doesnt have a transaction; because if it does then the problem comes back
Now if I execute the package then my checkpoint shows that the first dataflow has already been executed and thus it will not execute this one again and it starts at the second dataflow upon re-execution.
I can work around it (with the empty script-task) but still I am wondering as to why this is happening. I am very interested to hear whether this is really a bug or if it is intended behaviour (and if it is then why is it intended?)

Hi,
I have two input columns (both DT_I4) in a column collection to a Aggregator transform. Now I am doing a group by to one and Count to another column.
To my surprise the output's column datatype is changed for Count Transform (DT_UI8) and I have to put extra Data Conversion Transfrom to get my DT_I4 datatype back.
Is this a bug or feature.

A new developer tried to import a data file using the ImportExport wizard. Unfortuantely, the file had several format errors and the process aborted after reading one bad line. (I imported it using a BIDS package with error handling. The file had 454 bad rows.)
Are there any options in the I/E Wizard to logskip errors but continue processing? After all, the I/E Wizard is designed for quick-and-dirty use and if it can't "handle" erroneous data "gracefully", it is not a very practical tool.
TIA,

I am currently using the SSIS Logging feature in my SSIS package. Currently, I have defined a destination log file, and each time the package is executed the log file gets appended with that days log.
Im trying to figure out how best to keep the log file name static (it gets emailed out, and my email client looks for a particular log file name) yet include only todays log information and append the rest of the log information to a history log file or something like that.
Has anyone tried doing something similar, or have any ideas on how best this can be accomplished?

Hi - I'm short of SQL experience and hacking my way through creating a simple search feature for a personal project. I would be very grateful if anyone could help me out with writing a stored procedure. Problem: I have two tables with three columns indexed for full-text search. So far I have been able to successfully execute the following query returning matching row ids: dbo.Search_Articles @searchText varchar(150) AS SELECT ArticleID FROM articles WHERE CONTAINS(Description, @searchText) OR CONTAINS(Title, @searchText) UNION SELECT ArticleID FROM article_pages WHERE CONTAINS(Text, @searchText); RETURN This returns the ArticleID for any articles or article_pages records where there is a text match. I ultimately need the stored procedure to return all columns from the articles table for matches and not just the StoryID. Seems like maybe I should try using some kind of JOIN on the result of the UNION above and the articles table? But I have so far been unable to figure out how to do this as I can't seem to declare a name for the result table of the UNION above. Perhaps there is another more eloquent solution? Thanks! Peter

Our clients want to be able to do full text search with a single letter. (Is the name Newton, Nathan, Nick?, Is the ID N1, N2...). Doing a single character full text search on a table work 25 out of 26 times. The letter that doesn't work is 'n'. the WHERE clause CONTAINS(full_text_field, ' "n*" ') returns all rows, even rows that have no 'n' in them anywhere. Adding a second letter after the "n" works as expected.
Here is an example
create table TestFullTextSearch (
Id int not null,
AllText nvarchar(400)
)
create unique index test_tfts on TestFullTextSearch(Id);
create fulltext catalog ftcat_tfts;
[Code] ....
