Accent insensitive Search - plz help me correcting this query

Hello,
I just realized that with that query, if I search for "Montreal" (without the accent), I have all the following results, which is what I want
SELECT
"ID","TIT"
from   "REGDOSSIERS" "RDO"
       where
         TRANSLATE(UPPER("TIT"),'ÀÂÉÈÊÎÔÛÙÜ','AAEEEIOUUU')
         like upper(nvl(replace('%' || "P1_REPORT_SEARCH || '%',' ','%'),"TIT"))
RESULTS
TIT
Annuaires Lovell (Montréal et banlieue)
Juridiction royale de Montréal. Dossiers, 1677-1769
Montreal Witness, 1845-1938
{code}
But how to change it so when I look for: "Montréal" (with the accent) , I have also the same results? Right now, with Montréal, I have nothing
thanks,
Roseline

If you are on Oracle 10g you can use regexp expressions to do the search.
Example
with testdata as (select 'Montreal' txt from dual
                  union all select 'Montréal' txt from dual
                  union all select 'Montreâl' txt from dual
                  union all select 'Montreaux' txt from dual)
/* end of test data creation */
select txt from testdata
where regexp_like (txt, 'Montr[[=e=]]al');
txt
Montreal
Montréal[[=e=]] would be an equivalence class for the letter "e" and includes also searches for é, è, ê etc.
The best solution mainly depends how your search string is build.
If you just want to sort, then the nlssort function would be useful.
Mentioning Nlssort I remembered there is a much better way to implement Accent insensitive search. You just need to set your NLS_SORT parameter correctly. Either to BINARY_AI (the AI means accent and case insensitiv) or add _AI to your nls langage.
example
ALTER SESSION SET NLS_COMP=LINGUISTIC;
alter session set nls_sort = 'FRENCH';
with testdata as (select 'Montreal' txt from dual
                  union all select 'Montréal' txt from dual
                  union all select 'Montreâl' txt from dual
                  union all select 'Montreaux' txt from dual)
/* end of test data creation */
select txt from testdata
where txt = 'MONTREAL';
no rows selects
/* now change the nls sorting */
alter session set nls_sort = 'FRENCH_AI';
with testdata as (select 'Montreal' txt from dual
                  union all select 'Montréal' txt from dual
                  union all select 'Montreâl' txt from dual
                  union all select 'Montreaux' txt from dual)
/* end of test data creation */
select txt from testdata
where txt = 'MONTREAL';
txt
Montreal
Montréal
MontreâlEdited by: Sven W. on Oct 2, 2009 8:34 AM

Plz help me design this query

Hi,
Can you’ll please help me with this query.
Here is a little bit of background:
One title can have multiple items associated with it.
Table: TITLE has the master list of titles. TITLE_ID is the primary key.
Table: ITEM has the master list of all items. ITEM_ID is the primary. This table also has the TITLE_ID which stores title for this item.
Table: ITEM_STATUS has fields ITEM_ID and STATUS_ID. This field contains statuses for items. But not all items contained in the table ITEM are in this table.
I want to find TITLE_ID’s whose all items (all ITEM_ID in table ITEM having same value for TITLE_ID) have a particular status (for example STATUS_ID = 2) in table ITEM_STATUS.
Let’s say TITLE_ID = 1 has 5 items in table ITEM_ID and only 4 items out of it in table ITEM_STATUS with STATUS_ID = 2, then this TITLE_ID should not come. OR
Let’s say TITLE_ID = 1 has 5 items in table ITEM_ID and all these 5 items are in table ITEM_STATUS but only 1 has STATUS_ID = 2, then this TITLE_ID should also not come
In the above case only if all 5 items are contained in table ITEM_STATUS have STATUS_ID = 2 then this TITLE_ID should be reported by the query.
What should be the query like for this one, I am fairly new to SQL so plz guide me.
Thank you,
Raja

I haven't tested the query below. Try it and let me know for any issues:
SELECT DISTINCT t.title_id
 FROM title t,
 item i,
 item_status its
WHERE t.title_id = i.title_id
 AND i.item_id = its.item_id
 AND NOT EXISTS (
 SELECT 1
 FROM item_status its1
 WHERE its1.item_id = i.item_id
 AND status_id <> 'YOUR_ITEM_STATUS'
 )

This seems to be a correlated query.
i tried using combined index on

and another index on
(LAN,VF_TYPE_CODE ,APPLICANT_TYPE ) but the plan or cost remains unchained.

At that point you're not too far off, you have most of what you need. In general, any time you see the use of DISTINCT it's a sign that either your query or your data model isn't designed quite right.
SELECT m.ename,
       d.dname,
       TO_CHAR (e.hiredate, 'YY') AS hire_year,
       COUNT(*) AS emp_count
FROM emp e, emp m, dept d
WHERE e.mgr = m.empno
   AND m.deptno = d.deptno
GROUP BY
       m.ename,
       d.dname,
       TO_CHAR (e.hiredate, 'YY');

And while writing query or any example so use the 6 digit before and after your query or example to keep the formatting in orignal format. Otherwise it becomes hard to read.

I'm not sure I understand your grouping goal, but...
select sales.product_id,
sales.quantity*sales.sales_rate sttl
pur.avgp
from sales
(select avg ( purchase_rate *
quantity) avgp,
product_id
from purchases
group by product_id) pur
where sales.product_id = pur.product_id
and sales.invoice_date between
'04-jun-1999' and '05-may-2001';
If you need more complex grouping, you can add it.

Hi,
Whenever you post fomatted text on this site (and code should always be formatted), type these 6 characters:
{code}
(small letters only, inside curly brackets) before and after sections of formatted text, to preserve spacing.
What is the problem?
Are you getting an error message?
Why not post the error message?
Are you getting the wrong results?
Post some sample data, and the results you want to get from that data.
NOT IN will never be TRUE if the sub-query includes any NULL rows. I can't tell if that's possible with your tables or not..

How to apply an accent-insensitive search to an interactive report?

Hello all!
I'm trying to put an accent-insensitive search on an interactive report here. For example, if I'm on the page that has the interactive report and if I click the column header of the interactive report, I get to see a search bar that dynamically shows the results that match your input. Now, when I enter "jager", I want to see *"Jägermeister"* as a search result. The search must be accent-insensitive, so that I don't have to enter the ä every time.
My code is as follows:
SELECT name
FROM food_1
WHERE name LIKE 'Jagerme%'
AND NLSSORT(name) IS NOT NULL
ORDER BY NLSSORT(name, 'NLS_SORT=GENERIC_M_AI');As you can see, I first tried getting a result through the SQL Command. It should return the row that has "Jägermeister" as name. However, it doesn't. It tells me "No data found". So, how do I alter my NLSSORT to search accent-insensitive?
Some extra information, I edited the interactive report source to the following:
SELECT DISTINCT a.name, a.foodid
FROM food_1 a INNER JOIN foodunit_1 c
ON a.foodid = c.foodid
WHERE a.foodlanguageid = :P17_SET_LANGUAGE
AND NLSSORT(a.name) IS NOT NULL
ORDER BY NLSSORT(a.name, 'NLS_SORT=GENERIC_M_AI');I also tried doing ALTER SESSION before the SQL code, but it still gives me the same result: No data found.
I'm using APEX version 4.1.1.00.23.
Help and suggestions are more than welcome. ;)
Thanks in advance,
Magali

I found it out!
It's really ridiculous, actually.
Remember this code?
execute immediate ('ALTER session SET NLS_COMP=LINGUISTIC');
execute immediate ('ALTER session SET NLS_SORT=BINARY_AI');Well, this code is perfectly fine. Only, it doesn't execute. This is because it was misplaced...This process is not executed when you place it in the current authentication scheme, under the "Post-Authenticatoin Process" part.
You might wonder why this is, but I have the explanation to that.
You see, when you use an interactive report, the page processing isn't executed when you use the search function of that interactive report... Because it's an interactive report, I guess.
BUT.
An ALTER SESSION from the security attributes, that will execute.
So, the solution to my problem was, in this case:
Go to "Application" --> "Shared Objects" --> "Security Attributes" --> "Database Session" --> "Initialization PL/SQL code". In there, you need to put:
BEGIN
EXECUTE IMMEDIATE 'ALTER session SET NLS_COMP=LINGUISTIC';
EXECUTE IMMEDIATE 'ALTER session SET NLS_SORT=BINARY_AI';
END;By doing this, there's no longer any need to edit the source code of the report!
So, that's the solution. I can finally enter text without special characters in it, and get the corresponding data, with special characters... Ahh. :)
I hope this is helpful to others as well now. ;)

Hi,
Welcome to the forum! You'll find that there are many qualified people (such as Tubby) willing to help you. Will you do what you can to help them? In order to simplify the query you posted,someone will first have to understand what it does, what the tables that it uses are like, and what tools you have to work with (that is, what version of Oracle, and any other software you are using). To actually test their ideas, people will need versions of your tables.
Many people, if they spent enough time, might be able to figure out roughly what you are doing, make some tables themselves and test a solution. You can help with all of that. I assume you already know what the appliction is, and what this particular query is supposed to do: you don't have to figure out any of that, you just have to say it. You know what all your tables are, what the datatypes of all the columns are, and what kinds of data are in the tables: you don't have to guess at any of that.
Describe what you're doing. Think about it: how do we know that
SELECT NULL
FROM dual;doesn't do what you want?
Post CREATE TABLE and INSERT statements for a little sample data.
Post the results that this query is supposed to produce from those results. (Is it producing the right output now? Then it should be easy to post the correct results.)
Describe, as well as you can, how the present query is doing it.
Format your existing code, so it's easy to see what the different branches of the UNION are, and what the main clauses are in each one.
When posting formatted text (code or results) type these 6 characters
\(all small letters, inside curly brackets) before and after each formatted section, to keep this site from compressing the spaces.
Say what versions of Oracle (e.g. 10.2.0.3.0) and any other relevant software you are using.
I know it's a lot of work, but it really helps. You can do it as well (probably better) than anyone else, and if you're unwilling to do it, why should anyone else be willing?

When you see something like ...
 7 - filter(TO_NUMBER("C"."RESTART_FLAG")=0) It means that Oracle had to do a conversion for you since you aren't using the proper data type in your query.
That would mean IF there is an index on that column, it won't be useable...

Accent insensitive Search - plz help me correcting this query
