Powerful Search Technique..
Apr 14, 2007
hello.
How to do Search in the method which is done in MSDN library 2005 (local application)?
i.e enabling a search filter and then (most incredibly) as you type the criteria, the
list gets updated depending on the characters entered.
for eg. you type: loo
and obtain the following display:
Look in dialog box
Look tab
lookaheads
l
l
l
l

Hi,
I need to implement a search procedure for my site that is able to traverse so many tables for results but at the same time making sure not to expose information that is sensitive and I sort of need help to do this as I have not actually done one as big as this one. I need to go through data on Petitions, users, schools and so many other tables in my database to find strings that match the search criteria but I am also conscious that this may cause some security problems with the way I think of it now and i was wondering if any one has a better idea on how to write a search procedure to allow user's to search my site for information.
Thanks in Advance

If you put an index on an integer type column named 'test_column' in a table that had 1,000,000,000 rows in it, and you said select top 50 * from test_table WHERE test_column = 1 since 'test_column' has an index, that would perform extremly fast wouldn't it? Cheers

I have an existing Access database that I need to transfer over to a more powerful back-end due to the need for larger size capacity. We need to be able to have a backend that can exist up to just about any size due to us scanning in documents by ODBC. With Access I know I was limited to about 4gb size and when split onto my current SQL server I have heard I will be stuck at 10gb? If so can you recommend a better backend, but my question is about the front end. I hear Windows WPF can be linked into SQL server but does this limit the size as well?

Hi,
We have recently upgraded our production server from a dual pentium II 400mhz server with 384Mb of RAM to a triple 700mhz Pentium III system with 2gb of RAM . However, since switching over, all of our Access queries on the SQL7 databases are either running extremely slowly or not at all despite the DSN's being set up correctly . Does anyone have any ideas why, and more importantly, how I can resolve this???
Thanks

Hello Members and Contributors and All the Peoples, Assalamualikum;
I am a Univesity Student and Currently i am creating my own website on ASP.
I have little bit of problem in Personal Message or Private Message Section.
What i want is that my Message Box Field of PM Should render HTML tags.. like here , in this website, Message Box renders HTML tags.. also here it has option to see the HTML view...
ALSO in my SQL Database the maximum length of my PM is 4,000... obviously that field will not store if it increases the limit. So how i increase my PM Field Length. Because i have put the option of replying the message... and old message will be shown as quoted message so all the text is very much important and what technique should use to STOP <a href> tags

I'm a newbie when it comes to the SQL Server side of things. I've been doingAccess on and off for years.I've got a form that is the main point of entry for all data.As a matter of technique, should I use one stored procedure to validate data(testing for uniqueness mostly) then another one to actually write the datato the tables?Does it make a difference one way or another to the performance?Do I gain any flexibility in my app dong it that way (Access Data Project)?Your help is appreciated.--Jake

Hi, we currently use binding to bind data from an SQL Query to a DataGrid, the problem is that we offer the choice to the user to choose the field that he want to see in the grid.
We currently include ALL optional field in the query even if they are not used by the grid, that make a realy big query with MANY inner and left outer join.
Whats the best techinique to dynamicaly construct my query with the field that the user choose.
All suggestion or webpage link will be appreciated.
Thanks a lot.

I need to write a query in an SP that returns either yes or no. Is it bad technique to use the return value of the SP for this? Should I use a scalar or output parameter instead? If so which?

Hi AllI'm creating some SPs and I've got a query which is inserting datainto a table with a a unique constraint:CREATE TABLE [fil_Films] ([fil_ID] [int] IDENTITY (1, 1) NOT NULL ,[fil_Film] [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOTNULL ,CONSTRAINT [PK_Tfil_Film] PRIMARY KEY NONCLUSTERED([fil_ID]) ON [PRIMARY] ,CONSTRAINT [IX_fil_Films] UNIQUE NONCLUSTERED([fil_Film]) ON [PRIMARY]) ON [PRIMARY]GOWhen I insert data, should I check in the SP to see if there is anexisting record or simply catch the error if it already exists? Whichis the better technique? My current SP looks like:CREATE PROCEDURE spAddFilm (@Type varchar(50)) ASDECLARE @Count intSET NOCOUNT ONSELECT @Count = Count(fil_ID) FROM fil_Films WHERE fil_Films.fil_Film= @TypeIF @COUNT IS NULLBEGININSERT INTO dbo.Tfil_Film (Tfil_Type) VALUES (@Type)RETURN 1 -- OKENDELSEBEGINRETURN 2 -- ExistsENDGOThanksSam

Been handed a system which inserts millions of records per day into a single table with a composite 'wide' index (they tell me it's the only way to achieve uniqueness) and they run large financial reports from this 300,000,000 row table and of course we are I/O is an understatment.
I wish to split the data feed (inserts) workload away from the reporting tables however I need method to transfer the feed data into the report tables and control the volume of traffic. first choice is replication but is this sufficiently robust enough for a commodeties system? If not any ideas?

Looking for some insight from the professionals about how they handlerow inserts. Specifically single row inserts through a storedprocedure versus bulk inserts.One argument are people who say all inserts (and updates and deletionsI guess) should go through stored procedures. The reasoning is thatthe developers that code the client side have no reason to understandHOW the data is stored, just that it is. Another problem is an insertthat deals with multiple tables. It would be very easy for thedeveloper to forget a step. That last point also applies to businesslogic. In my case, adding a security to our SecurityMaster can touch 1to 4 tables depending on the type of security. Also, certain fieldsare required while others are set to null for depending on the type.Because a stored procedure cannot be passed datasets but only scalarvalues, when you need to deal with multiple (i.e. bulk) rows you arestuck using cursors. This post is NOT about the pros and cons ofcursors. There are plenty of those on the boards (some of themprobably started by me and showing my understanding (or morecorrectly, lack of) of the way to do things). Stored procedures alsogive you the ability to abort and/or log inserts that cannot happenbecause of contraints and/or business rule failures.Another approach is to write code (not accessible from outside thedatabase) that handles bulk inserts. You would need to write in rulesto "extract" or "exclude" rows that do not match constraints orbusiness rules otherwise ALL the inserts would fail because of one badrow. I guess you could put the "potential" rows into a temp table.Apply your rules to the temp table and delete / move rows that wouldfail. Any rows left can that be bulk inserted. (You could also use therows that were moved to another temp table for logging why theyfailed.)So that leaves use with two possible ways to get data into the system.A single row based approach for client apps and a bulk based forinternal use. But that leaves use with another problem. You now havebusiness logic in TWO separate areas. You have to remember to modifycode or fix bugs in multiple locations.For those that are still reading my post, my question is...How do you handle this? What is the approach you take?

I've been asked to turn our single-user database system into a multi-usersystem. At present, each user has a copy of the MSDE on their desktopmachine and uses our program to access it. In future, we would like tocentralise our MSDE instance and allow multiple users to access it. Inorder to facilitate this, we are going to only allow one user write accessto the system at a time (I know, its a kludge, but the system was neverdesigned for multiple users in the first place).I have a single, simple question this being the case: can I update a single"read-only" bit field in a table of the database in order to flag to otherusers that the system is in read-only mode in a way that avoids concurrencyissues? ie. does an "UPDATE" query lock and unlock? ( I suspect the answeris yes! ). If anyone else has experience of these things, I would alsoappreciate some tips on how best to proceed.ThanksRobin

Hi folks, I have implemented this technique to simplify SCD loads and also to maintain consistent units of work during update/insert of a single row. Wanted to get your feedback on this technique: performance, transaction issues, etc.
I send all rows to an OLE DB Command that performs both update and insert for a single row in a single command:
Code Snippet
UPDATE PROPERTY SET ORD_TERM_DT = ? WHERE ACCOUNT_NBR = ? AND ORD_TERM_DT = '9999-12-31 23:59:59';
INSERT INTO PROPERTY (
ACCOUNT_NBR
, APPRAISAL_COMPANY_CD
, .....
, ORD_TERM_DT
) VALUES (?, ...,?);
This way I can guarantee that if the termination (update) of an old row (say, row 10) succeeds, but insert of the new row 10 fails, that it will roll back. Otherwise, row 10 will get terminated without being replaced with a current record...
Performance: load of 7,734 changed records into a table of 6.8M existing records was roughly 8 seconds. The data flow task container TransactionOption = Required.

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

Colleagues:
I'm working through the DM tutorials and I can't select a data mining technique when creating a new mining structure in BI Studio - BI Studio locks up totally. Have installed SQL Svr 20005 SP1 and components from feature pack. Analysis Server service is running, have set the properties in the DM project properties to the running instance of Analysis Services. Have read the various posts on the forum and have double checked my configuration - all seems as it should be.
All suggestions appreciated - very much looking forward to working with the technology.

Hello geniuses
First of all I would like to announce that this is my first time I post here.. However, I'm pretty sure that I'm in the best place to ask what I want. To cut the story short, I'm querying SQL database on a remote machine and having the result saved (mapped) to another table on another database on the same remote machine. The thing is the destination table was empty before the query was run the first time. I have been searching for some smart way so that when I modify the source tables that my query is based on, it doesn't affect except the modified rows. In other words, it should be like if the row is already there, do nothing. otherwise, it updates the existig record. else, it's a new record and it's inserted. I think what i need will include some coding for sure, yes? I don't know if i'm clear about the requirement or not though! but I know that you are experts and can direct me. Waiting for your valuable replies.

Hi All,
We have this SSIS package that serves a ETL role, but sometimes when the package crashes we wanted our support personnel to be aware of it, so we did implement an Event handler Package, executable is the package and Event Handler on taskFailed. The idea is if any of the Tasks fail, then trigger the event handler.
Now recently I found out while debugging the package, one of the DFT's failed, and the control went to the Event handler. But thenrest of the Task's are executing and the package finished successfully.
How do I ensure that if at all some Tasks fail, the control should invoke the task at the event handler and end the package run.
One more query, what is the ideal and best way of Event handling to be followed in case of ETL jobs ?
Thanks in Advance.

Hi,Env: MS SQL Server 2000DB Info (sorry no DDL nor sample data):tblA has 147249 rows -- clustered index on pk (one key ofdatatype(int)) andhas two clumns, both are being used in joins;intersecTbl4AB has 207016 rows -- clustered index on two fks andthis intersection table has six colums but only the two fks are beingused for joins;tblB has 117597 rows -- clustered index on pk (one key ofdatatype(bigint)) andhas four columns but only its key are being used for joinsA complex query involving the above the three tables includes innerand outer joins, aggregate, sorting, predicate, math function, derivedtable etc.On the first run, the query takes about 4200ms to finish;after some research on index optimization, I provided some index hint,then the query runs atabout 3000ms. (That was yesterday).Just now I realized that MS SQL Server 2000 is quite "intelligent", Ithink it saves search termsinto cache because the second time search of the a same term is muchmuch faster. Now, a couple of questions:a) if I construct a long long list of "common" terms andprogrammatically let the sql server to cache them would it speed upthe overal query performance in my case? (Or it may depend on thequality of the "common" terms?) and if your answer is yes (supposedlyyou've been there, do you have to know where I could find such a"common" term list, for everyday life or the general public?)b) what other techniques out there to speed up the above describedquery? Bring it down to 1000ms would be most desirable.Thanks.

I had a problem with the ntext datatype. I need to strip the HTML tags out of a ntext datatype column. I have sample query for that, which works fine for STRING, as stuff is the string function, what to do for ntext field.
=======The Process follows like this =========
--**************************************
--
-- Name: A relational technique to strip

-- Description:A relational technique to
-- strip the HTML tags out of a string. Th
-- is solution demonstrates how to use simp
-- le tables & search functions effectively
-- in SQL Server to solve procedural / ite
-- rative problems.
-- This table contains the tags to be re
-- placed. The % in <head%>
-- will take care of any extra informati
-- on in the tag that you needn't worry
-- about as a whole. In any case, this t
-- able contains all the tags that needs
-- to be search & replaced.
CREATE TABLE #html ( tag varchar(30) )
INSERT #html VALUES ( '<html>' )
INSERT #html VALUES ( '<head%>' )
INSERT #html VALUES ( '<title%>' )
INSERT #html VALUES ( '<link%>' )
INSERT #html VALUES ( '</title>' )
INSERT #html VALUES ( '</head>' )
INSERT #html VALUES ( '<body%>' )
INSERT #html VALUES ( '</html>' )
go
-- A simple table with the HTML strings
CREATE TABLE #t ( id tinyint IDENTITY , string varchar(255) )
INSERT #t VALUES (
'<HTML><HEAD><TITLE>Some Name</TITLE>
<LINK REL="stylesheet" HREF="/style.css" TYPE="text/css" ></HEAD>

go
-- This is the code to strip the tags out.
-- It finds the starting location of eac

Hi I have a production table in SQL Server 2005 that has approx 500,000 records---every 6 hours this table needs to be truncated and filled
The basic SSIS package uses a script compentant and imports the data into a staging table which has the same structure as the production table. I have a final Execute SQL Task that Truncates the production table and does a Insert into production-select * from stage table.
Takes around 30 seconds to run this last Execute SQL Task--problem is there is a risk that our webservice will query this table during the Execute SQL Task and return incorrect results.
Q1: In this last Execute SQL Task if I used a BEGIN TRANSACTION and COMMIT TRANSACTION; will this be any quicker ?
Q2: In this last Execute SQL Task- would it be better to use a RENAME TABLE technique in TSQL--any code examples ??
Q3:Is there any way in TSQL I can compare EVERY FIELD in two tables ie Stage and Production which have identical data structures and figure out a way to update only the records that changed? Is SQL Server Replication the best way to do this
thanks kindly
Dave

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] ....

I have a scenario of where the standard Full-Text search identifies keywords but Semantic Search does not recognize them as keywords. I'm hoping to understand why Semantic Search might not recognize them. The context this is being used in medical terminology and the specific key words I noticed missing right off the bat were medications.
For instance, if I put the following string into a FT indexed table
'J9355 - Trastuzumab (Herceptin)'
AND
'J9355 - Trastuzumab emtansine'
The Semantic Search recognized 'Herceptin' and 'Emtansine' but not 'Trastuzumab'
Nor in
'J8999 - Everolimus (Afinitor)'
It did not recognize 'Afinitor' as a keyword.
In all cases the Base of Full-Text did find those keywords and were identifiable using the dmvsys.dm_fts_index_keywords_by_document.It does show the index as having completed.
why certain words might not be picked up while others would be? Could it be a language/dictionary issue? I am using English and accent insensitive settings?

would you use sql server "full text search" feature as your site index? from some reason i can't make index server my site search catalog, and i wonder if the full text is the solution. i think that i wll have to you create new table called some thing like "site text" and i will need to write every text twice- one the the table (let's say "articles table") and one to the text. other wise- there is problems finding the right urlof the text, searching different tables with different columns name and so on...
so i thought create site search table, with the columns:
id, text, url
and to write every thing to this table.
but some how ot look the wrong way, that every forum post, every article, album picture or joke will insert twice to the sqr server...
what do you think?
