Problem with MySQL Full-Text Search

31-Jul-12 11:14

one more question please..

if I have the string as

jassim rahma

jassim ali rahma

or anything else

how can split that to be:

<pre>SELECT file_no, old_file_no, account_number, id_number, full_name, date_of_birth FROM patients WHERE MATCH(full_name) AGAINST('jassim' WITH QUERY EXPANSION) and MATCH(full_name) AGAINST('rahma' WITH QUERY EXPANSION) ORDER BY full_name;</pre>

I am using the following statement:

SQL

SELECT * FROM patients WHERE MATCH(full_name) AGAINST('jassim ali' WITH QUERY EXPANSION) ORDER BY full_name;

what I want to display all records contains jassim and should also contains ali but getting totally different result! here are names I am getting in the result:

Abdul Rahma Salma
Ali Jassim
Jassim Rahma
Jassim Rahma
Mohd Ali Ahmed
Mohd Jassim Maki

Never tried that. But I guess, and AND with two clauses could do the trick:

SQL

SELECT * 
FROM patients 
WHERE MATCH(full_name) AGAINST('jassim' WITH QUERY EXPANSION) 
  AND MATCH(full_name) AGAINST('ali' WITH QUERY EXPANSION) 
ORDER BY full_name;

Please try, and report failure or success.

Visual C# not showing up in my project type choices

31-Jul-12 11:18

I tried it but still the same problem. I am getting result which has no relation to the string entered! here is my result:

Abdul Rahma Salma
Ali Jassim
Jassim Rahma
Jassim Rahma
Mohd Jassim Maki

because it's returning Jassim OR Rahma but I want Jassim AND Rahma

Get the value of the texbox, split it into a string[] and use the elements of the array as parameters into your SQL query. Note, do not use string concatenation to create your query but proper SQL parameterisation.

One of these days I'm going to think of a really clever signature.

what is self hosting and IIS hosting?is there any difference of it

One difference of of course is that in one case one uses IIS (Internet Information Server) and in the other you don't.

Besides that, having used self hosting quite a bit but having never used IIS (in any way) my take (guess) is that there is some non-trivial part of WCF that is more apt for IIS than for self hosting. For example, the idea that a service 'restarts' isn't applicable for self hosting because the host app itself is either running or not running and that has nothing to do with WCF.

Also there is a WCF forum.

Hi
I need to run a query on a stock table. Each product may exist in either one or many warehouses. I am trying to find all items where the cost of the product is not the same in warehouse 01 and 02.

Example

Wh Prod Cost
01 A 10.00
02 A 10.00
01 B 64.00
01 C 98.00
02 C 10.00

In the example data above, I would like to get the last two rows returned.

This is what I have tried, but get lots of the same product code

SELECT stockm.warehouse, stockm.product, stockm.standard_material FROM
(SELECT product, standard_material FROM scheme_stockm WHERE warehouse = '01') AS A,
(SELECT product, standard_material FROM scheme_stockm WHERE warehouse = '02') AS B,
scheme_stockm AS stockm
WHERE (A.product = B.product AND A.standard_material <> B.standard_material)
ORDER BY stockm.product, stockm.warehouse

I think you are close ... but try this:

SQL

SELECT A.warehouse, A.product, A.standard_material,B.warehouse, B.product, B.standard_material FROM
(SELECT product, standard_material FROM scheme_stockm WHERE warehouse = '01') AS A,
(SELECT product, standard_material FROM scheme_stockm WHERE warehouse = '02') AS B
WHERE (A.product = B.product AND A.standard_material <> B.standard_material)
ORDER BY A.product, A.warehouse

I believe you included the scheme_stockm too many times in your original query.

Thanks David

I had to add warehouse in the two select statements for warehouse '01' and warehouse '02' since they were referred to in the outer SELECT as below and now it works.

SELECT A.warehouse, A.product, A.standard_material,B.warehouse, B.product, B.standard_material FROM
(SELECT warehouse, product, standard_material FROM scheme_stockm WHERE warehouse = '01') AS A,
(SELECT warehouse, product, standard_material FROM scheme_stockm WHERE warehouse = '02') AS B
WHERE (A.product = B.product AND A.standard_material <> B.standard_material)
ORDER BY A.product, A.warehouse

I also got mine to work by adding an additional 'join' as below on stockm.product = A.product, but I prefer yours, since the result is one record per error, whereas mine is two records per error

SELECT stockm.warehouse, stockm.product, stockm.standard_material FROM
(SELECT product, standard_material FROM scheme_stockm WHERE warehouse = '01') AS A,
(SELECT product, standard_material FROM scheme_stockm WHERE warehouse = '02') AS B,
scheme_stockm AS stockm
WHERE (A.product = B.product AND A.standard_material <> B.standard_material AND stockm.product = A.product)
ORDER BY stockm.product, stockm.warehouse

Cool

Your query will only work if you have 2 warehouses. What happens if there are 3 or more? Try:

SQL

SELECT
    a.warehouse,
    a.product,
    a.standard_material
FROM
    scheme_stockm AS a
WHERE
    EXISTS (SELECT * 
            FROM scheme_stockm 
            WHERE product = a.product AND 
                  standard_material <> a.standard_material)
ORDER BY
    a.product,
    a.warehouse

Hi Michael

I had wondered about multiple warehouses Smile | :)

In this particular case the product can exist in other warehouses, however the cost in the others does not need to be the same - only warehouse 01 and 02 must be the same.

I did test your query, and it works perfectly!

Thanks as I'm sure I'll need something like this in the future

Searching Content of Documents in Database

Hi all,
If I were an employer searching for resumes which contain skill sets that match my search criteria, how is that done from a programmer's perspective. Can we actually go inside of text documents in a database and search their contents? If not, I will have to add a Skills field to the database so that it can be searched. Any suggestions will be greatly appreciated, thanks in advance.

That wouldn't be very efficient.

What type of documents do you expect, besides PDF, Word and the OpenOffice format? Whenever your end-user uploads a document, save it twice; once the original document, once a text-only version. Each of those formats can be "read" with the help of some libraries, and the text can be extracted. The text-version of the document can easily be searched, and once you find a "match", you display the original document.

For searching the text-versions of the uploaded documents, take a look at the Full Text Search[^] article on MSDN. If you're using another version than Sql2008, you can change it to match your specific version with a drop-down list at the top of the page.

Including a "Skills" field might still be beneficial, besides the FTS. Keep in mind that users will have different labels for the same role/function/job, and that managing those is the hardest part. For example, one of the major Dutch websites has different entries for "Software Developer", "Software Engineer" and the dutch word for "Software Developer".

Hope this helps a bit Smile | :)

When I wrote one of these in the 90s we required word docs only, then we compared each word in the document with a list of skills, if there was a kit it was added to the skills set for that document.
