I have to perform a weighted search. I have 2 criteria and each will be weighted on a 100 sum(e.g 25/75, 50/50). I am just wondering if there is an easy way to encompass a weighted value on SELECTS. Sorry if this is a dumb question.
Thanks,

SQL Server 2005:
Anyone know how best to rewrite this SQL string to perform a weighted search on my table?
here's my code:
SQL="SELECT RecipeName FROM recipeList WHERE FREETEXT(*,'ISABOUT " & ing01 & " WEIGHT (.1) or " & ing02 & " WEIGHT (.2) or " & ing03 & " WEIGHT (.3) or " & ing04 & " WEIGHT (.4) or " & ing05 & " WEIGHT (.5)')"
the idea is to get a list of recipes most pertinant to the ingredients entered.
table 'recipeList' contains the ingredients in several columns. so column 2 might say '5oz of flour', column 2 - '2oz butter' etc.
at the moment it returns the correct recipes but not in the right order.
If I use 'CONTAINS' it returns nothing.
hope that's not too vague!
I need to run some statistics on a dataset. I've never used SUM or COUNT(*) before, but I'm pretty sure I need them for this. If this is my table:
GROUP nvarchar(10) QTY tinyint TYPE smallint VALUE decimal(3,2)
g1 q1 t1 v1
g1 q1 t2 v2
g2 q2 t1 v3
g2 q2 t2 v4
g3 q3 t1 v5
g3 q3 t2 v6
g4 q4 t3 v7
and I need this output
v1 * q1 / (q1 + q2 + q3 + q4) + v3 * q2 / (q1 + q2 + q3 + q4) + v5 * q3 / (q1 + q2 + q3 + q4)
v2 * q1 / (q1 + q2 + q3 + q4) + v4 * q2 / (q1 + q2 + q3 + q4) + v6 * q3 / (q1 + q2 + q3 + q4)
v7 * q4 / (q1 + q2 + q3 + q4)
how can I query this? I think that I have to group by TYPE, but other than that I don't know how to do this. Thanks for your help.
Does anyone know if it's possible to calculate weighted averages on report level, based on 2 items in the report?
View 6 Replies View RelatedHi there... I've got an interesting one, that I can't seem to get my head around. Maybe some legend out there might be able to give me a hand...
I'm looking for a way to produce a weighted set of random numbers. I'm doing some work for a client at the moment, and they want to issue 3 random "reward cards" to their members at certain times. These are a bit like discount vouchers etc. The problem is some cards have need to have a higher frequency than the others. I guess a similar problem to baseball cards, you buy a pack of cards, you get mostly common cards, but every now and then, you get a rare card.
Here is the table setup:
CREATE TABLE [dbo].[Cards](
[CardID] [uniqueidentifier] NOT NULL CONSTRAINT [DF_Cards_CardID] DEFAULT (newid()),
[CardName] [nvarchar](50) NOT NULL,
[InsertRatio] [float] NULL,
CONSTRAINT [PK_Cards] PRIMARY KEY CLUSTERED
(
[CardID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 1', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 2', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 3', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 4', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 5', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 6', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 7', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 8', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Common 9', NULL) /* Null implies the card is a common card */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Rare 1', 0.02) /* 1:50 ratio */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Rare 2', 0.02) /* 1:50 ratio */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Rare 3', 0.02) /* 1:50 ratio */
INSERT INTO [dbo].[Cards]([CardName],[InsertRatio]) VALUES('Very Rare 1', 0.005) /* 1:200 ratio */
So what I need to do, is have a Stored Proc that I can execute and it returns back 3 random rows. Now in that single run, a card can't be duplicated.
Notice the Insert Ratio column? This has the ratio of the probability, eg a 1:50 insert ratio is equal to 0.02. For the common cards, a NULL value indicates it is a common.
Eventually, this table would have about 1000 rows in it, and about 200 of those would have various ratios (eg 1:50, 1:200, 1:1000, 1:8000 etc)
Any ideas or comments?
Thanks in advance.

Hi,Does anyone know of a script that will give "weighted job duration"?I want to use it, to identify which jobs are hogging the CPU. That isfor a given server, list the sql agent jobs ordered by:(avg job duration in minutes) times (avg num of times job runs in agiven day).
View 2 Replies View RelatedPerhaps is just brain drain but i cannot seem find an efficient query to join two tables (inv and supplier) such that an inv item can have multiple suppliers and i would like to choose the prefered supplier based on the current 'weight' column.
declare @inv table (item varchar(50), supplierid int)
declare @supplier table (supplierid int, weight int)
set nocount on
insert into @inv values ('item1', 1)
insert into @inv values ('item1', 2)
insert into @inv values ('item2', 2)
insert into @inv values ('item2', 3)
insert into @supplier values(1, 30)
insert into @supplier values(2, 20)
insert into @supplier values(3, 10)
-- the query should return the item and the supplierid associated to the lowest weight
-- item1 -> supplier 2
-- item2 -> supplier 3
select item, ps2.supplierid from @supplier ps2 join
(select item, min(ps.weight)'weight'
from @inv inv join @supplier ps on inv.supplierid=ps.supplierid
group by item) iw on ps2.weight=iw.weight
Is there a better alternative to this?
Thanks in advance,

I have a question about writing a prediction query against a clustering model that has the same column added more than once.
Per Jamie, I can accomplish some crude weighting by adding a column to my model multiple times. See this post for an explnation... Now that I have that worked out, I was wondering how my DM query would look? If I have Input_A1, Input_A2 , & Input_A3 all being source from the same column in my structure do I have to reference all three when writing my prediction query?
I have a table in `PowerPivot` which contains the logged data of a traffic control camera mounted on a road. This table is filled the velocity and the number of vehicles that pass this camera during a specific time(e.g. 14:10 - 15:25). Now I want to know that how can I get the average velocity of cars for an specific hour and list them in a separate table with 24 rows(hour 0 - 23) where the second column of each row is the weighted average velocity of that hour?
A sample of my stat_table data is given below:
count vel hour
----- -------- ----
133 96.00237 15
117 91.45705 21
81 81.90521 6
2 84.29946 21
4 77.7841 18
1 140.8766 17
[Code] ....
In a separate `PowerPivot` table I have 24 rows and 2 columns(column1 is for hours and column 2 for weighted averages) and when I enter my formula, the whole rows get updated with the same number. My formula is:
=sumX(FILTER(stat_table, stat_table[hour]=[hour]), stat_table[count] * stat_table[vel])/sumX(FILTER(stat_table, stat_table[hour]=[hour]), stat_table[count])
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
I am using Naive Bayes, Decision Trees, and Neural Net (SSAS 2005) to predict which of two states each record belongs to.
How can I enforce a different penalty for a false positive versus a false negative ? (I am assuming that in some sense the mining algorithms can then minimize the total penalty).
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
View 3 Replies View RelatedOur 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?

Here is my Stored Procedure creation sql:
CREATE PROCEDURE sps_searchTitles(@searchTerm varchar(255)) AS

I have a table that contains words that will be used to search another table where FullText index has been created on searchable columns. I'm basically trying to run something like this:
SELECT t1.col1, t2.col3
FROM tbl1 t1, tbl2 t2
WHERE CONTAINS (t1.col1, t2.col1)
I know this won't work but is there a way to join these two tables so the words (t2.col1) can be passed as search conditions? There is no common key on both tables so normal join won't work. I'm trying to find a way to pass the search words from one table to another.
I have Sql server 2005 SP2.
I enabled it for Full Text search. Substring search where i enter *word* doesn't return any row.
I have a table testtable where description has word Extinguisher.
If i run a query with *ting* it doesn't return any row.
select * from testtable where contains(description,'"*xting*"') ;
But it works if i do
select * from testtable where contains(description,'"Exting*"') ;
The Full text search document says it supports substring search.

I am using Sql Server 2014 Express edition.I have a table with a varchar(max) column. I have created a full text search that use the stoplist "system". column has this struct: xxx.yyy.zzz.... where xxx, yyy, zzz... are numbers, like 123.345.123123.366456...I can have rows like that:

select * from Mytable where
contains(MyColumn, '123.345.')

select * from MyTable where

My site uses a text box to allow visitors to search products. I'm trying to design the SQL Statement to allow search's on full words, part words, and words/phrases regardless of the order the words are in.
E.g.
megger
meg
mft megger (proper order in the database is megger mft)
mft1710 (using 1710 should find the product)
This is my select statement (classic ASP)
Code:

RSResults__param5 = "xxx"
If (Request("searchme") <> "") Then
RSResults__param5 = Request("searchme")

Hi guys
I need to create an "advanced search" which will allow the user to narrow down his results.
Ideally I'd want him/her to use the same search criteria form for each iteration, with a checkbox called "Search within results" type of thing.
Now what I was wondering if there was any existing literature on how to effectively do this. I have tried doing it just through SQL Statements but they are becoming very messy and large.
Is it possible to do this by searching the initial dataset, returning dataset #2 and then if a 3rd "search within results" is done apply the search against dataset #2 and return dataset #3 etc?
Many Thanks
John
