skeleton for this need

With the help of dynamic
Creating a procedure with three parameters p_colname varchar2, varchar2, p_ref ref_cursor p_value emp_data

Based on the value in the p_colname and the emp table p_value query and return the result set in a cursor.

Validate the value of the p_colname, you need a valid column_name in emp table

can u give the skeleton for that... I'm nt get how to REF Cursor as a parameter

Oracle's solution for this need for specific research.

Hello

We are on Oracle 11.2.0.2 on Solaris 10. We need to be able to search on data that have diacritics and we should be able to make the serach ignoring this diacritical. That is the requirement. Now, I could hear that Oracle Text has a preference called BASIC_LEXER which can ignore diacritics and so only this feature I implemented Oracle Text and just for this DIACRITIC search and no other need.

I mean I put up preferably like this:

  ctxsys.ctx_ddl.create_preference ('cust_lexer', 'BASIC_LEXER');
  ctxsys.ctx_ddl.set_attribute ('cust_lexer', 'base_letter', 'YES'); -- removes diacritics


With this I set up like this:

CREATE TABLE TEXT_TEST
(
  NAME  VARCHAR2(255 BYTE)
);

--created Oracle Text index

CREATE INDEX TEXT_TEST_IDX1 ON TEXT_TEST
(NAME)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('LEXER cust_lexer WORDLIST cust_wl SYNC (ON COMMIT)');
--sample data to illustrate the problem

Insert into TEXT_TEST
   (NAME)
 Values
   ('muller');
Insert into TEXT_TEST
   (NAME)
 Values
   ('müller');
Insert into TEXT_TEST
   (NAME)
 Values
   ('MULLER');
Insert into TEXT_TEST
   (NAME)
 Values
   ('MÜLLER');
Insert into TEXT_TEST
   (NAME)
 Values
   ('PAUL HERNANDEZ');
Insert into TEXT_TEST
   (NAME)
 Values
   ('CHRISTOPHER Phil');
COMMIT;

--Now there is an alternative solution that is there,  instead of thee Oracle Text which is just a plain function given below (and it seems to work neat for my simple need of removing diacritical characters effect in search)
--I need to evaluate which is better given my specific needs -the function below or Oracle Text.

CREATE OR REPLACE FUNCTION remove_dia(p_value IN VARCHAR2, p_doUpper IN VARCHAR2 := 'Y')
RETURN VARCHAR2 DETERMINISTIC
IS
OUTPUT_STR VARCHAR2(4000);
begin
IF (p_doUpper = 'Y') THEN
   OUTPUT_STR := UPPER(p_value);
ELSE
   OUTPUT_STR := p_value;
END IF;

OUTPUT_STR := TRANSLATE(OUTPUT_STR,'ÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÑÒÓÔÕÖØÙÚÛÜÝàáâãäåçèéêëìíîïñòóôõöøùúûüýÿ', 'AAAAAACEEEEIIIINOOOOOOUUUUYaaaaaaceeeeiiiinoooooouuuuyy');

RETURN (OUTPUT_STR);
end;
/



--now I query for which name stats with  a P%:
--Below query gets me unexpected result of one row as I am using Oracle Text where each word is parsed for search using CONTAINS...
SQL> select * from text_test where contains(name,'P%')>0;

My need any only had to be able to do a search that ignores diacritical characters. To implement Oracle Text for this reason, I was wondering if it was the right choice! More when I find now that the functionality of the TYPE is not available in Oracle Text - Oracle text search are based on chips, or words, and they differ from the exit of the LIKE operator. So, maybe I just used a simple like function below and used that for my purpose instead of using Oracle Text:

Just this feature (remove_dia) removes diacritical characters and maybe for my need is all what is needed. Can anyone help to revisit that given my need I better do not use Oracle text? I need to continue to use the feature of as operator and also need to bypass the diacritics so the simple function that I satisfied my need while Oracle Text causes a change in the behavior of search queries.

Thank you
OrauserN

If what you need is AS feature and you do not have one of the features of Oracle complex search text, then I would not use Oracle Text. I would create an index based on a function on your name column that uses your function that removes diacritical marks, so that your searches will be faster. Please see the demo below.

I can't update Firefox, my computer is claiming that I need permission admin (everything else to date very well) I am the admin for this computer and I have the password. Any ideas?

I can't update Firefox, I tried to disable Firewall etc. My computer says I need permission admin to update Firefox, even if I am the owner and the administrator of this computer. There are updates available and know the password for this computer. It all started when I installed the Noscript tool (that I tried to disable them with the same results)

This has happened

If you have Mac OS X 10.5 or newer then follow these steps:

"You are not allowed to change the settings for this printer. If you need to change the settings, contact your system administrator.

XP Pro, SP3. I downloaded the free Bullzip pdf printer. Somehow my old printer pdf in my printer disappeared list which I have used for years. I get this message when installing - "you are not allowed to change the settings for this printer. If you need to change the settings, contact your system administrator. I click ok and it ends, but it doesn't work. It does not appear in the printer control panel as a printer to change anything.

I built this computer at home and I'm the only one using it. What is this function 'administrator '? I've never had to administrator on any program. Never. That is what it is?

CNET is infamous for the grouping of things in its downloads as much a / v programs report as junk (I went through the same thing using eSet NOD32 has / v). I seem to remember that if you ignore the warning and download the exe file and then use a tool like the free 7-zip to extract only the file necessary to run the program you want, you can work around the problem.

For a pdf printer free which is not CNET - and works well - go here--> http://www.cutepdf.com/products/cutepdf/writer.asp

Aspire laptop DVD player GONE! SlimType DVD A D58A4SH need a fix for this DVD player

Is there a fix out there for a problem loading the driver for CD/DVD Acer Aspire of the laptop drive? I have the Aspire 5334 with DVD Super Multi DL drive.

I have a Slimtype DVD A D58A4SH player. He worked for a short time when I got the notebook and then it stopped completely. There was an exclamation point on the list of devices and when I checked to see if the pilot that it has been updated, he said it was the last updated, etc. BUT still does not. I tried to roll back - which did not work. So I uninstalled the drive completely. Did a restart and it recognizes the DVD drive and started to install the driver for it. Says the driver installation failed. The dvd player is no longer listed in Device Manager. I tried to go to the download page of support/driver from the Acer website for this brand and the computer model - it does not list DVD drivers at all. So now I'm confused. It was a Christmas gift from 2011. So I think that the warranty has expired. So I'm pretty ticked if I need to replace a failed drive which is just came out barely a month outside the warranty of the year. Someone out there who has a fix for this problem it will be greatly appreciated. Thank you.

I found a FIX for this problem! Yay!

I had an error Code 39 and did a search on the Microsoft Web site. Here is the link. I followed the "method 2" and it worked Finally, got my rear DVD player. Phew!

Your Internet drivers are not part of XP. If you bought the device from Dell, you have other records besides that reinstall drive? I had 3 machines from Dell and they all came with the CD of drivers among others.

You can do in PSE.
1. Do the math to see how much space you'll need on your canvas to the image and text.
2. Navigate to the file queue > new.blank. Enter the width & height, background color, resolution 72 px / in. It is your canvas, and in the layers palette will be the background layer.
3. Copy and paste the image. It turns on a separate layer
4. Activate the tool move, position the image and resize if necessary
5. Activate the text tool, and then type your text. It will be on a separate so layer
6. Position the text.
7. Flatten layers and go to file > save for web. I'm usually on the long side about 800 px. Don't forget to check "constrain proportions". Adjust the quality slider to suit. You will probably want the type of JPEG file for web work.

You probably want confirmation from an Adobe employee and I do not work for the company, but its completely legal to post images and videos done with and on Photoshop that you use a legal version of the software. Of course if you copy videos from someone else so they can possibly file a lawsuit against you for plagiarism or copyright violation, but I suspect that your not likely to do
