Dear VB coders!
I have 8.000 or 16.000 products on my list in an sql table. It takes 8 or 16 secs to find the last item.
How could I make the search faster? Indexing? But how?
I created:
createTable1.CommandText = "Create TABLE products (ID int IDENTITY(0,1) PRIMARY KEY, name ntext)"
and I use simple WHERE to search.
Thank you!
I recently installed SQL2005 Express on a Dell Precision workstation to be accessed by 6 users. The PC has XP Pro, 2GB memory, and 2.0GHz core2due CPU. This PC is dedicated for the database only.
I also set XP Performance options in System Properties to Background services and System cache.
Now, the users are experiencing slow response from the database.
How can I make the database response faster?
Thanks for your input.
Hi.We have stored procedure update specific table
Each time it run it delete 5000- 6000 rows
from table then insert 5000- 6000 rows with different information.
It take up to 1 1/2 min execute.
1.Can force Sql server do not make entry for each insert and if yes would it increase speed of procedure ?
2. Is any other way increase speed of insert?
I need help makeing the following query run more efficently.
Code:
SELECT t1.ID,t1.firstName,t1.lastName,t1.address,t1.city,t1.state, t1.zip,t1.locationAddress,t1.locationCity,t1.locationState,t1.locationZip
FROM Landlord_tbl t1
left outer join Mail_tbl t2
ON t2.potentialSitesID = t1.potentialSitesID
WHERE t2.mailed_out_date is null and NOT(t1.firstName+t1.lastName) is Null
GROUP BY t1.ID,t1.firstName,t1.lastName,t1.address,t1.city,t1.state, t1.zip,t1.locationAddress,t1.locationCity,t1.locationState,t1.locationZip
ORDER BY t1.firstName, t1.lastName, t1.city, t1.state
Hi:
I have thousands of rows that I have to retrieve for my report. When I run my main report it returns my data as a reasonable time.
When I run my sub report (by its own) again data are returned in reasonable time.
When I build the sub report in my main report it takes forever (I have to stop). Are there any tricks that I can use to make this run faster?
Thank you in advance

Hi,
Here is the typical processing I do in Data Flow
1) read data file (data source)
2) do something with the data (e.g. derived column, script component, etc)
3) pass data as parameters into OLE DB command (stored proc) to take care of the rest.
Would it be faster if
I split the data into say 10 "chunks" (using split transform). Each chunk will go to its own OLE DB command (10 OLE DB command). Now I will have 10 concurrent processes running the stored proc ?
Am i misunderstanding concurrent process here ?
Thanks

Any ideas how to make reports faster when returning lots fo rows?
I know you would need to work on your sql query etc..
Or maybe cache it.
But i'm thinking of having a kind of middle tier thing that sits between your sql database and the reports itself.
Any ideas would be appreciated
It seems when I run the query with the set staticts IO on then statistic reports back with the 'work table', and the query takes 30+ sec. if the worktable is ommited(whatever the reason?) the query take less 1 sec.
Here is my take, I believe work table is created in tempdb...and if not then whole query is using the cached page, am I right?
if I am right then the theory is, if I increase the (via sp_configure) server min memory setting and min query memory, the query ought use the cached page and return in less 1 sec. (specially there is absolutely no one but me on the server), so far I can't make it go faster...what setting am I missing to make it run faster?
Another question is if the query can not avoid but use the tempdb, is it going to always be 30 sec+ time? why is tempdb involvement make it go so much slower?
Thanks in for you help in advance
Hello.
I have an OLTP database and alot of users that is querying against that.
I am thinking of a way to store a more denormalized version of some tables in another database, and use that for a search function that we have.
The problem is that the base tables are updated all the time with new and new data. And the search cannot have that long delay but a delay of 5-10 minutes for updates/insert is ok. deletes though cannot have any delay.
I was thinking of a SCD-setup and when a delete goes against the OLTP then we also run a delete against the SCD-database. But is it possible to create a SCD-database and have it update every 5-10 minutes?
I have also been thinking of a queue-table (and store updates/inserts) in the OLTP-database and then run a query every 5 min against the queue-table and update the denormalized version of the table. But isnt this a longer way? Why not update the denormalized version of the table directly when the OLAP-tables is updated?
I have also been thinking of to truncate and then fill the denormalized version every 5-10 minute from the OLTP-version. Maybe have two tables and after the fill is complete do a rename of the two tables, so that we wont lock the table that long while filling it up with the new data.
The denormalized version would contain around 200k rows.
Any suggestions is appreciated.
Thanks

I intend to develop a web based application, which uses SQL server 2005 at back end and Visual studio 2.0 as front end.
Application serves two functionalities
Requirement1: It carryout a search (In SQL server) for a particular name entered from front end .net application against a huge DataBase of size about 1 million records.
Scenario: The above requirement can be complemented by following example
Consider we have a bank database which has its existing customer DataBase having containing attributes like Name, Age, and Profession e.t.c.
Now if some new customer want to open a new account in bank, then bank officials want to know whether the
new customer is one of the existing customer or not(without asking to customer itself).
System should be able to detect the combination of name also i.e if we enter "Jhon" from front end .net interface
then application should be able generate all list of all customer having "Jhon" as part of their name at any location(firstname, middlename, lastname).
Requirement 2: If some time change is detected in bank's extisting customer's DataBase then each record of this DataBase is searched against a external dataBase(having almost 2 -3 million records).
Scenario: The above requirement can be complemented by following example
If new user is added to bank's existing customer database(database change) then this new updated database's every record is serarched against another bank's database.
I would like to hear experts voice for database design of such application for optimal performance,and types of searches I should look for application.
Hello everybody,
I have installed SQLServer 2005 for take advantage of full text seach features.
When I start full population, there are some rows that cause error and not are indexed.
I see the log in C:ProgrammiMicrosoft SQL ServerMSSQL.1MSSQLLOGSQLFT0000700005.LOG. In this file there are seven rows that have error and for everyone a line that say:
"Error '0x8004fd01: The IFilter::Init() function call failed.' ... full-text key value 0x495532303045594154504B55. Attempt will be made to reindex it. The component 'pdffilt.dll' reported error while indexing. Component path 'C:ProgrammiFoxit SoftwareFoxit PDF IFilterpdffilt.dll'."
With different full-text key value for every line.
My question is:
1) Start from a full-text key (ie. 0x495532303045594154504B55), how I arrive to the record in the source table for understand which is the problem?Otherwise how can I examine the problem if I don't know the row that cause the error?
2) What is the error 0x8004fd01?
3) Could be that the PDF filter of Foxit is better than Adobe? With Adobe filter (version 6) my full pupulation is endless!
Thanks!
I am about to heavily index a table and have to include atleast 3 to 4 olumns in the fulltext index for this table.
The table is updated very frequently and the also the columns that are involve in the fulltext indexing undergo frequent updates.
As of now, I can't avoid using full text indexing as these columns are very very lengthy and basically contail text.
The users of the database will give some key words as the search criteria
to get infomation as to what they are looking for.
How frequently should I update my full text catalog.
This is a scenario where the full text is operating on various tables and
each of thses table might be containingaround 300,000 to 800,00 rows.
I would appreciate an intelligent siggestion as I need it as soon as possible.
Thanks and have a wonderful time ahead.
We have an iFilter to extract text on emails and their attached files. I have encountered 5 emails that receive the following error code, but I cannot find anything on the error code: Error '0x80fc7586' occurred during full-text index population for table or indexed view '[RIA_Unindexed].[dbo].[Emails]' (table or indexed view ID '485576768', database ID '31'), full-text key value 'E11264A2-A17D-E511-80E0-005056B240B1'. Attempt will be made to reindex it.After a number of retry attempts they will fail to index.what does error code  '0x80fc7586' refer to, I have not found it.
Since the first two bytes of the error code are the severity and facility reporting the error, I stripped off that information and looked for error 0x7586 or 30086. That error reported "Too Many products".Theses emails being indexed contain attachments with large attachments that then the attachment chunks are being called for from the fdhost may result in too many chunk segments, or more likely there are some repeating words in the extracts like 4 million occurrences so right now I am testing that condition. To see if the word breaker is throwing the error.
Hi
I have a Full Text index on a table with an image field that is successfully indexing .doc, .pdf and .rtf files.
Keyword searching this is no problem.
What i want to be able to do is perform a similarity search. by this i mean pass in a Key_ID (documentID) and have the database return a list of Key_IDs (documents) which are similar.
By similar i mean contain mostly the same keywords in roughly the same quantities
Thanks
Hi, I was wondering if any SQL Server gurus out there could help me...I
have a table which contains text resources for my application. The text
resources are multi-lingual so I've read that if I add a html language
indicator meta tag e.g.<META NAME="MS.LOCALE" CONTENT="ES">and
store the text in a varbinary column with a supporting Document Type
column containing ".html" of varchar(5) then the full text index
service should be intelligent about the language word breakers it
applies when indexing the text. (I hope this is correct technique for
best multi-lingual support in a single table?)However, when I come to query this data the results always return 0 rows (no errors are encountered). e.g.DECLARE @SearchWord nvarchar(256)SET @SearchWord = 'search' -- Yes, this word is definitely present in my resources.SELECT * FROM Resource WHERE CONTAINS(Document, @SearchWord)I'm a little puzzled as Full Text search is working fine on another table that employs an nvarchar column (just plain text, no html).Does the filter used for full text indexing of html expect certain tags to be present as standard? E.g. <html> and <body> tags? At present the data I have stored might look like this (no html or body wrapping tags):Example record 1 data: <META NAME="MS.LOCALE" CONTENT="EN">Search for keywords:Example record 2 data: <META NAME="MS.LOCALE" CONTENT="EN">Sorry no results were found for your search.etc.Any pointers / suggestions would be greatly appreciated. Cheers,Gavin.UPDATE: I have tried wrapping the text in more usual html tags and re-built the full text index but I still never get any rows returned for my query results. Example of content wrapping tried - <HTML><HEAD><META NAME="MS.LOCALE" CONTENT="EN"></HEAD><BODY>Test text.</BODY></HTML>I've also tried stripping all html tags from the content and set the Document Type column = .txt but I still get no rows returned?!?

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?

Hi all, I m new to this forum and this is my first question. I m having 2 pages in my web site ... page 1 query directly to db using sqldatasource, the second page query through a BLL then DAL by following the step in this tutorial (http://www.asp.net/learn/dataaccess/tutorial02vb.aspx?tabid=63).... Page 1 is using a "Like" query search and the Page 2 is the normal displaying some product detail.... Under normal circumstances, one will expect Page 1 will be way fastest than the Page 2... however the problem is Page 1 is in thunder speed while Page 2 takes 10 secs to load... 10 seconds is really not acceptable... I really couldnt figure out what happens... both Page 1 and Page 2 are using the same connection string which connection through a DSN.... How is the connection different by using sqldatasource and DAL?? Could someone please help.... ThanksP.S. I m using a Pervasive database
