ContainsTable Function Searching Only One Column Per Record

Oct 25, 2007

Hello all,

I am using the ContainsTable function to search a database from my (c#) app. This works relatively well and all fields of the table are indexed and searched. That is, any column, but per record only one column.
What I mean is this: when searching for "chris 2007", I want to retrieve all items where author contains chris and year contains 2007. Currently, a search for chris brings up all items where author (or any other field) contains chris, a search for 2007 works as well, but chris 2007 fails as there is no -one- field where chris and 2007 are located.
Can anybody help me achieve this? My code is:




Code Block
SELECT FT_TBL.ID, FT_TBL.Type, FT_TBL.Author, IsNull(FT_TBL.Author, FT_TBL.Editor + ' (Ed.)') AS CorrectedAuthor, FT_TBL.Editor, FT_TBL.Title, FT_TBL.Abstract, FT_TBL.Comments, FT_TBL.Year, FT_TBL.City, FT_TBL.Publisher, FT_TBL.ISBN, FT_TBL.Pages, FT_TBL.Journal, FT_TBL.Issue, FT_TBL.Hyperlink, FT_TBL.Tags, KEY_TBL.RANK
FROM Sources AS FT_TBL
INNER JOIN CONTAINSTABLE(Sources, *, @searchQuery) AS KEY_TBL ON FT_TBL.ID = KEY_TBL.[KEY]
ORDER BY KEY_TBL.RANK DESC;



What am I doing wrong?

Thanks in advance,

Chris

Full Text Search And CONTAINSTABLE - Can I Weight By Column?

Aug 8, 2006

I'm trying to use CONTAINSTABLE to do a product search on a number of columns. I want matches on some columns to be weighted higher than for other columns.

It seems like there should be a way to do this with CONTAINSTABLE - I know I can search by multiple strings and weight those matches variably, but what I want is to vary the weight by which column a single term matched. What I have now is a series of UNION queries, which are quite slow:
===================
SELECT m.TitleCode, m.ShortName, m.ShortDescription, a.Rank, 50 as theWeight
FROM CONTAINSTABLE (Product, ShortName, @theSearchTerm) as a, Product m(NoLock)
WHERE a.[KEY] = m.TitleCode

UNION ALL

SELECT m.TitleCode, m.ShortName, m.ShortDescription, a.Rank, 40 as theWeight
FROM FREETEXTTABLE (Product, ShortName, @theSearchTerm) as a, Product m(NoLock)
WHERE a.[KEY] = m.TitleCode

UNION ALL

SELECT m.TitleCode, m.ShortName, m.ShortDescription, a.Rank, 30 as theWeight
FROM FREETEXTTABLE (Product, MatchKeywords, @theSearchTerm) as a, Product m(NoLock)
WHERE a.[KEY] = m.TitleCode

UNION ALL

SELECT m.TitleCode, m.ShortName, m.ShortDescription, a.Rank, 20 as theWeight
FROM FREETEXTTABLE (Product, ShortDescription, @theSearchTerm) as a, Product m(NoLock)
WHERE a.[KEY] = m.TitleCode

ORDER BY 'theWeight' DESC, m.ShortName

===================

What is the better way?

T-SQL (SS2K8) :: Searching For Allowed Characters From Table Using Function?

Aug 10, 2015

I want to create a function that searches for allowed characters within a table range (that contains the allowed characters) and replace any characters outside this range with a space.

For example -

'Bill123?', 'Jones12.z-'
'John&12/', 'QWERT123&4'

Wanted results – the single quotes are there to show the space for the replaced characters.

'Bill123 '
'Jones12.z '
'John&12 '
'QWERT123 4'

Example SQL data

CREATE TABLE [Common].[AllowedCharacters] (
[Character] [varchar](1) NOT NULL,
[Replacement] [varchar](10) NULL,
[AlwaysInclude] [bit] NOT NULL)
GO
SET ANSI_PADDING OFF

[code]....

The function will wrap around the column names and I know it can be done without a table validate the characters but it must be done this way.

could I search for rows that contain 'adventure' in the column searched (lets call it columnA).  I tried:
select * from tbl_test where columnA LIKE 'adventure'    and got no results.
what is the way to do this?
 
Thank-you,

Column Locked In Record Even Though No One Accessing Record

Mar 18, 2008



Hello. I have a database with a record that has two columns locked. descrip1 and descrip2. they are both nvarchar(max) columns. These are the only two columns of the record that remain locked. I am certain no user is accessing the record. I have even moved a backup of the database to my testing computer and the lock still exists. How do I remove the lock from these two columns on that particular record.

I can edit these two columns on other records. I have researched "Unlock" on MSDN but it doesn't seem to apply to t-sql. Any help would be greatly appreciated.

Thanks. Gary.

Searching A Column For A Value To Avoid Inserting A Duplicate Value

Jul 17, 2007

Hi there, newbie here.
I'm building a web application that allows for tagging of items, using ASP.NET 2.0, C# and SQL Server.
I have my USERS, ITEMS and TAGS separated out into three tables, with an intersection table to connect them.
Imagine a user has found an item they are interested in and is about to tag it. They type their tag into a textbox and hit Enter.
Here's what I want to do:
I want to search the TagText column in my TAGS table, to see if the chosen tag is already in the table. If it is, the existing entry will be used in the new relationship the user is creating. Thus I avoid inserting a duplicate value in this column and save space. If the value is not already in the column, a new entry will be created.
Here's where I'm up to:
I can type a tag into a textbox and then feed it to a query, which returns any matches to a GridView control.
Now I'm stuck... I imagine I have to use "if else" scenario, but I'm unsure of the code I'll have to use. I also think that maybe ADO.NET could help me here, but I have not yet delved into this. Can anyone give me a few pointers to help me along?
 Cheers!

Searching For Dates In A Column Of Type Varchar

Feb 22, 2008



I have a DB named zCIFRecord with a column named CIFUpdateDate which is of datatype varchar. The data is a date MM/DD/YYYY 01/30/2008, this is al that is in this column. I can search this colum for individual dates and for a range of dates. My problem is with a range of dates that is not within the same year, such as;


SELECT [CIFPan]

,[CIFMemNum]

,[CIFLName]

,[CIFFName]

FROM [FutureSoft].[dbo].[zCIFRecord]

WHERE [CIFUpdateDate] between '12/01/2007' and '01/30/2008'


will return nothing because it seems to only search on the 12 then the 01 then the 2008. this search can be performed properly on dates within the same year such as;

SELECT [CIFPan]

,[CIFMemNum]

,[CIFLName]

,[CIFFName]

FROM [FutureSoft].[dbo].[zCIFRecord]

WHERE [CIFUpdateDate] between '01/01/2008' and '01/30/2008'

will return the proper values because now all the numbers are in correct order. How can i create a search that lets me perform the first query as well as the second query. I tried to convert to a float but you cant convert a varchar to a float.

Can I do something like this in RS -

I would like to call a function in a calculated field like
=code.GetNHW(Fields!id1.Value,Fields!date1.Value)
where the GetNHW() function would return a double value based on some conditions-
The code I would like to write in Code window-

Dim dsDTConfig As New DataSet
Dim NHW As Double
dsDTConfig = GetDS("tblEmployee_DailyTimingsConfig", "id=" & ID & " and '" & attDate & "' between configStartDate and configExpiryDate", False)
If dsDTConfig.Tables(0).Rows(0)("allowUnscheduledBreaks") = True Then
NHW = 0.01
ElseIf dsDTConfig.Tables(0).Rows(0)("allowUnscheduledBreaks") = False Then
NHW = 0.05
End If
Return NHW
End Function
What I am looking for is - I would want to get the record(dataset) within the function from the database
and based on the values got, I would check few conditions and calculate NHW.

Help: UNION Vs. CONTAINSTABLE

Jul 8, 2007

I have n Tables: T_1, T_2, ... T_n that all have the same exact fields/columns.
Ultimately, I want to search through ALL n tables and return a single table of relevant results from all tables, arranged in order by rank.
I'm not sure if this is possible. So far, I have:
 1 SELECT RANK, field_1, field_2, ..., field_m FROM
2 (
3 SELECT RANK, field_1, field_2, ..., field_m FROM T_1,
4 CONTAINSTABLE(T_1, field_i,@searchText) searchTable
5 WHERE KEY = T_1.field_i
6 UNION
7 SELECT RANK, field_1, field_2, ..., field_m FROM T_2,
8 CONTAINSTABLE(T_2, field_i,@searchText) searchTable
9 WHERE KEY = T_2.field_i
10 UNION
11 .
12 .
13 .

16 CONTAINSTABLE(T_n, field_i,@searchText) searchTable
17 WHERE KEY = T_n.field_i
18 )
19 ORDER BY RANK DESC

 I haven't tried it yet, but it seems wrong. How do we actually do this?

Is There A Way To Have List Of NOT Words With Containstable?

Nov 6, 2007

This works when @searchString is used in containstable (provided searchString has value)...

set @searchStringNoneOfWords = 'not(Airplane)'
SET @searchString = @searchString + ' AND ' + @searchStringNoneOfWords

This does NOT work when @searchString is used in containstable...

set @searchStringNoneOfWords = 'not(Airplane)'
SET @searchString = @searchStringNoneOfWords

I understand it is because the syntax is AND NOT, but what if I have a list of words that I do not want included? How do I start out with a NOT using containstable? It is kind of like Google's advanced search except that if you enter a word in the "without words" section with the other fields blank it would return everything under the sun except for things found with those words.

Difference Between FREETEXTTABLE And CONTAINSTABLE

Apr 8, 2008

Can somebody help me in identifying the difference between FREETEXTABLE and CONTAINSTABLE statements?


I have recently started experimenting with the free text search and I feel that FREETEXTTABLE can look for the search string into multiple columns by breaking it into tokens.

For example

select ft_tbl.saon, ft_tbl.paon, ft_tbl.street, ft_tbl.postcode
,key_tbl.rank
from temp as ft_tbl
INNER JOIN freetextTABLE(temp, (saon, paon, street), '80 ridge avenue', 15) as key_tbl
ON FT_tbl.ID = key_tbl.[key]

Now in my case €œ80€? is in PAON column and €œRidge Avenue€? is in STREET column. Among the resulting rows it also displays the required row. If I try to achieve this with CONTAINSTABLE using

select ft_tbl.saon, ft_tbl.paon, ft_tbl.street, ft_tbl.postcode
,key_tbl.rank
from temp as ft_tbl
INNER JOIN containsTABLE(temp, (saon, paon, street, postcode), '80 ridge avenue') as key_tbl
ON FT_tbl.ID = key_tbl.[key]

It gives me error
Syntax error near 'ridge' in the full-text search condition '80 ridge avenue'.

If I make search string as €˜€?80 ridge avenue€?€™ instead of €˜ridge avenue€™ then it doesn€™t give me error but also displays no results because 80 ridge avenue does not appear as whole in any single column. If I search by only specifying €œridge avenue€? in search string then I get a full list where street is ridge avenue.

My question is Does FREETEXTTABLE can search in all listed column by breaking the search string into tokens and CONTAINSTABLE only in one as whole?

Code That Return Correct Number Of Record When Run Without Aggregate Function

Nov 26, 2013

I have sql code that returns the correct number of record when run without an aggregate function like count(myfield) and group by myfield. It always returns 86 row which is correct when Select DISTINCT is used. As, expected when DISTINCT is not used I get double the number if rows or 172. But when I count(myfield) and group by myfield the count is 172 and not 86. The strangest thing about this is that when I am grouping a set of items

Group 1

Group 2

Group 3

The other group sum up correctly while others don't. What can explain this? Here is the code.

Select DISTINCT ws.p4Districtnumber, ws.cycle, ws.worksetid, count(msi.MeterSessionInputKey) as ASND
from fcs.dbo.WorkSet as ws
left outer join fcs.dbo.WorkAssignment as wa
on ws.WorkSetID = wa.WorkSetID
left outer join fcs.dbo.MeterSessionInput as msi
on wa.worksetkey = msi.worksetkey

CONTAINSTABLE: Query Multiple Columns With AND

Oct 9, 2003

Is there a simple and direct way to perform a fulltext query in a table with multiple columns, and to use AND over multiple columns? I've noticed that AND only works within one column.

Example: Take a column 'lastname' with 'jones' and 'smith' in it. Another column 'firstname' with 'alan' where lastname=smith. Search for 'alan and smith', and no results are returned because they are in different columns. If you would have a lastname 'alan smith', that would be found.

SELECT *

FROM tblTest t

Result is both records returned, but since the search is in quotes as an exact phrase, should not just the first record be returned?

Containstable Queries Not Making Sense.

Jan 2, 2008

I have a few questions related to using CONTAINSTABLE in a query that I hope someone can help with.

I am working on a project to add document search capabilities to my companies product using fulltext indexing. Part of this requirement is an ability to breakdown the component parts of of the search query and provide information on *why* documentX ranked higher than documentY.
This is a bit convoluted, but taking this (very simple) example - the user wishes to search for 2 skills - "HTML" and/or "XML".
The generated query looks a little like :-

Select DOC.DOC_ID, RANK1.RANK, RANK2.RANK, RANK3.RANK
from DOCS DOC
inner join CONTAINSTABLE(docs, doc, 'HTML AND XML') as RANK1 on RANK1.DOC_ID=DOC.DOC_ID
inner join CONTAINSTABLE(docs, doc, 'HTML') as RANK2 on RANK2.DOC_ID=DOC.DOC_ID
inner join CONTAINSTABLE(docs, doc, 'XML') as RANK3 on RANK3.DOC_ID=DOC.DOC_ID

This returns the "overall" rank, and a rank for the 2 component parts, so I can say this doc ranked XXX overall because it scored "rank1" for HTML and scored "rank2" for XML etc....

My question on this part is about the values for the "overall rank". If the query contained an OR it always seems to return the highest of the "rankX" values, and if it doesnt, it returns the lowest.
e.g. for the example
for java and word and excel and access - the overall ranking is 2 , java=36, word=2, excel=16 and access=36
for java and word or excel and access - the overall ranking is 16 , java=36, word=2, excel=16 and access=36
for (java and word) or (excel and access) - the overall ranking is 16 , java=36, word=2, excel=16 and access=36

So in the first example, regardless of what the other values are, the rank returned is always 2 (the score for "word"). My resultset has 100ish rows, all with a rank of < 5 for word, but all with ranks of 18-100 for the other 3 values - yet the "overall" rank always matched the "word" rank.....??
This doesnt feel right to me somehow, I would expect a different value as if the document ranked really highly for one value but low for the other, it doesnt feel right the value is clamped to the lowest? Or am I just understanding it wrong?
If I use "freetexttable" the overall rank is a little more meaningful - but unfortunately I also need to use weighting, which brings me to my next question . . .


This question is about rankings returned from the ISABOUT function.
In the following example,
select * from documents as DOC
inner join containstable(docs,doc,'project') as doc0 on DOC.DOC_ID=doc0."key"
inner join containstable(docs,doc,'ISABOUT (project weight (1.0))') as doc1 on DOC.DOC_ID=doc1."key"
inner join containstable(docs,doc,'ISABOUT (project weight (0.5))') as doc2 on DOC.DOC_ID=doc2."key"
inner join containstable(docs,doc,'ISABOUT (project weight (0.1))') as doc3 on DOC.DOC_ID=doc3."key"
inner join containstable(docs,doc,'ISABOUT (project weight (0.0))') as doc4 on DOC.DOC_ID=doc4."key"
order by doc0.rank desc

The values I get from the doc1/2/3/4.RANK columns dont seem right.
In this example,

doc0.rank = 133
doc1.rank = 150
doc2.rank = 330

doc3.rank = 924

doc4.rank = 0

These values dont make any sense to me, as the rank seems to go UP when the documentation on ISABOUT says it goes down (I think it says somewhere the calculated rank is multiplied by the weight?).
Once again, is there something I missed or am I understanding it wrong?

Thanks in advance for any help into understanding the whys of this...
