Wildcard In Simple Sql Search.
Mar 30, 2005
I'm very new to SQL so please forgive my ignorance...
I've made a simple .net search page which queries an sql database with the following query, (in a stored procedure):
SELECT Category, Number, RegisteredUser, DeptName, Surname, Forename, Site, IDFROM tblTelephonesWHERE (@surname IS NULL OR Surname LIKE @surname) AND (@site IS NULL OR Site = @site) AND (@deptname IS NULL OR DeptName LIKE @deptname)
This works fine, as expected if i leave fields null or enter an exact match, but I (of course) have to add a wildcard in my search string for a wildcard search. For example, looking for 'duncan' i need to enter 'du%' or 'duncan'.
What I really want is for all searches to have wildcards behind them so only the first few characters need be inputted, and I could just search for 'd' or 'dun' without adding the '%' to get 'duncan'. I think I am aware of the implications of this approach and do want to go ahead as there are only about 850 records.
Any help or links to useful articles would really be greatly appreciated.

Hi all, I am currently using SQL Server 2000and am having some issues when searching a CHAR column and using the WildCard character '%'. The problem is that when I use this WildCard character, the results returned (if any!) are incorrect. For example, I know that there are many rows in the DB that have the following data in a column, 'ABERYSTWYTH CEREDIGION', but when I using the following SQL...'(WHERE (UPPER(AddrLine3) = 'ABERYSTWYTH%')' I get no results returned.Is there a known issue with the WildCard character in SQL Server 2000?ThanksTryst

Hi,
I have a doubt about using a wildcar(% or *).
Can we use the the wildcard in query in the following way...
Select name from abcd where
(name like'%moh%'or name like '%raj%'or name like '%san%')
Is it allowed to use the wildcard at the biginning of the string. If any one says yes :Using the full text search is it possible to improve the query performance.
I thinking of that it is not allowed to use the wildcard at the beginning of the string.
Your comments and recommendation will be highly appreciated...
Thanks,
Mohammed.

hello,
i want to search for "any phrase here*" where i want it to match the exact same phrase and followed by anything. but the problem is that when using the following syntax: contains(myTbl,'"my phrase here*"') i will get results like "my123 phrases here" so the wildcard will be applied to the consecutive words and not the last word.
How can i search for an exact phrase followed by anything?
ps: i cant omit the wildcard becoz the last word is not exact
so treating the space as any other character and not as a seperator in the search_expression may be a solution but how to do it
Thanks

Hi All,
I have a company table with CompanyName and Address details.
In the Company Name field - I have got companies with names like - 'The 1% Club', '99% Pure Water', 'The 1% Golfer' etc...
I want to search for Companies with % using the LIKE clause - Say for ex.
SELECT CompanyName from Company WHERE CompanyName LIKE 'The 1%%'
I was expecting the above query to return - All Companies starting with 'The 1%' - So from the above list - I expected it to return - 'The 1% Club' and 'The 1% Golfer'.
Unfortunately the query isn;t accepting % in the WHERE LIKE clause except for the wildcard character.
Is there a way out to escape the Wildcard Characters present in the Field Values while searching.
Thanks,
Loonysan

Hi there,
I am trying to get the do a full text search using the CONTAINS operator and the asterisk wildcard prefix and apparently it is returning inconsistent results. I have a full-text enabled table named Content which contains an AutoId field with a clustering index built on it, a column named ContTitle which is fulltext indexed and a couple of other columns. The fulltext catalog has been fully populated.
When I perform this sample query:
SELECT AutoId, ContTitle FROM [Content] WHERE CONTAINS(ContTitle, ' "Live Band From Colombia" '),
it returns me a row, however when i change the sample query to include the asterisk wildcard behind the search phrase:
SELECT AutoId, ContTitle FROM [Content] WHERE CONTAINS(ContTitle, ' "Live Band From Colombia*" '),
it returns no rows.
I tried the to change the search phrase to "Excellence Service Award", for e.g.
SELECT AutoId, ContTitle FROM [Content] WHERE CONTAINS(ContTitle, ' "Excellence Service Award" '),
and
SELECT AutoId, ContTitle FROM [Content] WHERE CONTAINS(ContTitle, ' "Excellence Service Award*" '),
both queries will return rows with the content title Excellence Service Award
Does anyone know if I'm missing out on any anything, like the full text indexed is not populated correctly for e.g? It's just weird that the same kind of search will work on some rows and not for the rest. Thank you very much.

I am developing for a customer and they want a search facility that uses boolean logic and special characters. So they want to be able to add "AND" "OR" "NOT" "*" and "?". And for this to effect the search in the predicted way and ranked. I was wondering if there is any examples of this type of search implemented?

Hi, Im trying to create a simple search page to return a list of products from a table in a sql database. Id like to be able to search a product description column in a table I have called products using the contents of a text box. I was wondering how i can go about getting the search to check for all words the user types in rather than just a single word or an exact phrase. Im currently using the following sql query
SELECT [product_title], [product_description] FROM [products] WHERE ([product_description] LIKE '%' + @product_search + '%')
this works fine for single words and exact phrases but if i had product called 'fred w bloggs' and i enter 'fred bloggs' it will not return anything.
Please could anyone suggest how i shoud go about this?
Im not sure if my web hosting company will enable full text search or will this be required?
Thanks for any help!

Hi all I need to implement a search function in Asp.net. Its nothing complicated, just find out whether a value exists in a particular table and return a boolean accordingly. However, the table has about 300,000 records. Is simply querying the table from the web (SELECT barcode FROM tblProducts where ID=123) the best way considering the releant column has been indexed.Any pointers would be appreciated. Thanks

I have a table of articles:
-------------------------------------
Articles
-------------------------------------
ID | Date | Headline | Body
-------------------------------------
I'm trying to write a stored procedure that will search for a given keyword. Here's what I have:
CREATE PROCEDURE sproc_SearchArticles
(
@keyword varchar(50)
)
AS
SELECT ID, Date, Headline, Body
FROM Articles
WHERE Body LIKE %@keyword%
ORDER BY Date DESC
RETURN
That keeps giving me an error. If I put quotes around it, it will literally look for the term @keyword anywhere in the body.

I'm not trying to do anything too fancy; given a string, I just wanna see if anything in the column of my database matches the string. I'm using an SQL query that takes a string, then selects the data using LIKE %searchword%.This works fine when the user enters only one word. But I guess you can see that a problem arises when they enter more than one word.So how can I implement a very simple search that will take more than one word?

This question probably applies to Visual Web Developer but I don't know if it belongs in this Forum or that, sorry if you have to move it.
Hi there kind person reading this
I've created a stored procedure in SQL2000 that selects records where (name = @name) AND (site = @site). It works as I have tested it with Enterprise Manager.
I have also created a page with VWD that has a drop-down list populated with the site records and a text box. I have put an SQL data source on the page that is configured to select from the stored procedure. However, I can't set the @name and @site variables to collect from the ddl and txtbox through the wizard! I've tried selecting a Control as the source for @site but neither the ddl or txtbox appear in the control dropdown list. So I want to crack it with handwritten code.
Does anyone know of a post or article that can help me link the ddl and txtbox to a search button, which calls the stored procedure with the chosen variables allowing me to put the returned data into a gridview? I've been through a great walkthrough for VWD (Student Activities) but it doesn't seem to apply to the latest version - or there's something wrong with my (seems fine though) instalation. Thanks if you can help, I owe you a

I have a table of news articles:
-------------------------------------
Articles
-------------------------------------
ID | Headline | Article
-------------------------------------
I'm trying to write a search function that will search through the text in the Article column. Here's my stored procedure:
ALTER PROCEDURE sproc_SearchNews
(
@keyword varchar(50)
)
AS
SELECTID, Headline, Article
FROMArticles
WHEREArticle LIKE '%' + REPLACE(@keyword, '%20', '%') + '%'
RETURN
There's a few problems with this however...
1. If I enter "Dog" into the search, it will skip over the article if it contains "dog". I need to convert the search term and the article text to lowercase.
2. If I enter "iron" into the search, it will find articles containing "iron", but it will also find articles containing "environment". How can I fix that without affecting my multiple word search in the WHERE clause?

Hello,
I have a search form in an ASP.NET/VB page. The form has the input text box and the button "search". The keywords are passed in the URL to results.aspx.
Here is an example of what I get in the URL, when I write the keywords "asp", "book" and "london" in the input text box and click "search":
results.aspx?search=asp%20book%20london
The database table has 3 fields: "id", "title" and "description".
I want to display all the records where at least one of the keywords is found in any of the 2 fields "title" and "description".
1. I suppose I need to get the words out of the URL to be used by SQL.
Maybe: string[] searchString = request.queryString("search").split('search'); ???
How can i make this run when page loads? I supose i need it. Right?
2. How should the SQL look? I supose i need to use the "Like" command
SELECT * FROM books WHERE title LIKE ...
But how to I use it if I can have 1, 2, 3, ... keywords?
Can someone help me?
Thanks,
Miguel

I've got an nvarchar(max) column that I need to transform with some simple text processing: insert some markup at the very beginning, and insert some markup just before a particular regular expression is matched (or at the end, if no match is found).
Since the SSIS expression language doesn't support anything like this, is a Script Component the only way to go? Does Visual Basic .NET provide regular expression matching?
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

Hello everyone and thanks for your help in advance. I am working on an application that does a property search off of a database that contains approximately 40000 records. The search criteria allows the use to specify a minimum and maximum price, subdivision name, number of bedrooms, etc. I set up a stored procedure to query the databse. if one of the parameters is not specified, i simply pass it a "%". However, when i execute this sproc in Query Analyzer, it takes in excess of 10 seconds to return the records, even if only one or two are returned. I am assuming this is due to the use of the wildcard character when the user does not have a preference, but I am not sure of any other way to do this. Any help on this topic would be grealy appreciated.

I am trying to control how users view records. I want to create a solution that would, for instance permit:user A to view Store 1user B to view store 2 and store 3user C to view store 5 and store 6and User D to view all stores even if more stores were added in the future (in other words user D would have access to all records)
I want to create an 'authorization table' so that different users can see different records. I think the easiest way to do this is to pass a parameter to the where clause, but the problem that I face is the how can I use a wildcard in a SQL 'IN' clause? Does anyone have any suggestions. Perhaps I am taking the wrong approach. I would appreciate any guidance.
