How to find database duplicates

I have a dynamic site that I made using Dreamweaver 802. It
has a database that has really grown and as I enter new names into
the database, I have found that there are some duplicates.
Is there a way to find duplicates in either Dreamweaver or
maybe PHPMyAdmin?
BTW, I have an admin menu that I setup to sort several
different ways, but none that works well for finding dupes. The
database has over 8,000 names and addresses and has become very
difficult to find these dupes.

I think you said you are using PHP so I'm not sure if this
applies as I do
ASP, but I would use SQL DataShaping.
I would create my "parent" recordset with the below Query and
then the
"child" recordset would display all the records using the
"parent" as the
criteria. It's actually pretty easy, check out this tutorial:
http://www.4guysfromrolla.com/webtech/092599-1.shtml
You could also create a nested repeat.

Hi,
as Daan said, set the variable in Advanced tab but not on loglevel..
because, our problem is to bypass the bi-server cache.
Do this:
1. Go to Advanced tab.
2. In Prefix field(scroll down to see this field) , enter this:
SET DISABLE_CACHE_HIT = 1;
Note: Make sure that you're ended up above statement with semicolon and do not click on Set SQL option...
3. Save report, then run it..
4. After you see the query, i recommend you to take take out that prefix tag then save it again..

Hi Experts,
For my project I have written a program for flat file upload.
Requirement 1
In the flat file there may be some duplicate record like:
Field1   Field2
11        test1
11        test2
12        test3
13        test4
Field1 is primary key.
Can you please let me know how I can find out the duplicate record.
Requirement 2
The flat file contains the header row as shown above
Field1   Field2
How our program can skip this record and start reading / inserting records from row no 2 ie
11        test1
onwards.
Thanks

How to find database table for field in CRMD_ORDER?

Hello,
in CRMD_ORDER there is a field CRMT_7850_SERVICE_UI-DURATION.
The structure is CRMT_7850_SERVICE_UI
The fieldname is DURATION
How can i find out in which database table content of this field is stored?
Thanks a lot
Best regards
Manfred

Hi,
When you execute report CRM_ORDER_READ (trx. se38), entering your order nr, you will get
an overview of all the underlying tables and their entries of the order.
E.g. you will find structure ET_SERVICE_H, corresponding to table CRMD_SERVICE_H;
structure ET_SERVICE_I, corresponding to table CRMD_SERVICE_I.
I expect your field (duration) to be in CRMD_SERVICE_I.
regards,
Wim

How to find database attribute names that correspond to page labels

I've been tasked with creating one or more views to be used in creating reports. The users know data items by the labels on pages, not the database attribute names. So my dilemma is how to correlate the page labels to the database attributes.
For example, there's a course details web page. It includes items labeled "Replacement Course", "Inherited Competency Update Setting" and "Attachments", among others.
Focusing on "Inherited Competency Update Setting"... there's no database attribute called that. I've found COMPETENCY_UPDATE_LEVEL, but I don't know if that is it. And is an "inherited" one different than a non-inherited.
I've googled about, and discovered that "Inherited Competency Update Setting" can be set by using a workflow named OTA_COMPETENCE_UPDATE_JSP_PRC and setting an attribute named HR_APPROVAL_REQ_FLAG. Further research has lead me to determine that HR_APPROVAL_REQ_FLAG is used only within the workflow system. I've found in SYS.ALL_SOURCE a package OTA_COMPETENCE_SS with a function that gets that attribute's value. It includes a query against WF_ACTIVITY_ATTR_VALUES which retrieves values of YES_DYNAMIC, APPROVAL, NO, YES or NOTIFYONLY. I've not found any code that uses the function.
Using ALL_TAB_COLUMNS, I'd found COMPETENCY_UPDATE_LEVEL in OTA_OFFERINGS, which contains "APPROVAL" or null. So that may be what I seek, but I can't confirm it.
I also have been unable to find the translation from "APPROVAL" to "Notification, Automatic Update after Approval" (assuming I'm correct and this is the field)
I've found a Training Administration Technical Reference Manual for Release 11i, which contains information about the database, but I've found no corresponding document for Learning Management for 12.1 (Only installation and user guides).
And this is many days' research to find one attribute. Which I'm not certain I've found.
So, in this case in particular, or any case in general, how does one find the database name for an attribute, given the page label's text??
Thank you
Cornell

Whoa, easier than I'd thought...
When the page first shows up, there's the About This Page link, at the bottom, clicking it you get to the About Page.
I noted two sections, Page Definition and Business Component References Details.
I expanded Business Component References Details and found View Objects. There's a list of views used. I was dismayed that the views don't appear to be in the database. Of course, they're camelCased Java names of Java objects, not database names (although sometimes some of the camelCased tokens might correspond to parts of view names). They are, however, clickable and when clicked the definition shows up, and I was thinking that it would take a long while to find what I was seeking.
But... Hit the Expand All link in Page Definition, do a find on page for the desired label, and there it is... a row with the label, view object name and attribute! Pay dirt!
Then go to the Business Component References Details, find the View Object, click it, and there's the view :-) Find the attribute, then the table... easy peasy!
Thank y'all again

How to find database files location (from system flat files)

Hi all,
Is there anyone who could help me to understand the Oracle database starting mechanism. I'm looking the doc for a few days, but it lacks some details...
I'm currently using Oracle 10g on RedHat, and my database has been created using DBCA. While the installation process, DBCA allows to use a customized location for "*all the database files*". I've chosen */data*.
Now, when I'm looking in my /etc/oratab file, I can see: mydb:$ORACLE_HOME:N
I guess the startup process of Oracle reads /etc/oratab (or I didn't understand its utility...) and then goes to $ORACLE_HOME to find the database infos. In this directory, I can see a directory named hostname_mydb/ and dbs/
The dbs/ directory contains my pfile (initmydb.ora) which contains some parameters such as control files, but nothing about the parent directory of my database files, ie:
control_files= /data/oradata/mydb/control01.ctl,....*
but no DB_CREATE_FILE_DEST as I could expect if the db was created through OMF.
The hostname_mydb/ contains nothing but a sysman directory.
I wonder how Oracle process knows where are the .dbf files or the "parent directory of database files" ? Does anyone have a clue?
I know it is possible to ask through sqlplus for .dbf location but I don't think it's the way used for the startup process (or at least, I hope there is another way)
Thanks! (and sorry if the question seems obvious or stupid...)

Thank you very much CPKT for all these details. It helps me to see clearer!
You are right, I have configure an Oracle Enterprise Manager and I didn't notice this directory was related to it...
And as I first thought, many data are in the binary control file. I just thought Oracle was a more simple system :)
You mention an Architecture Guide for DBA, is it the Database Concepts manual mentioned in the first reply or is it another manual (I can't find it, but obviously I have to improve my searching technique...)

Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to tahiti.oracle.com.
Drill down to your product and version.
BOOKMARK THAT LOCATION
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- Read a chapter a day from the Concepts Manual.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them (listed in your alert log) in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- When you have finished reading the Concepts Manual, do it again.

2. scan the table and run the "combined" (means you combined every row from below separated by a space) the below output into name2 column
with t as (
 select 'Sachin Tendulkar Ramesh' col from dual
 select TRIM(substr (splitted,
 instr (splitted, ' ', 1, level ) + 1,
 instr (splitted, ' ', 1, level+1) - instr (splitted, ' ', 1, level) -1 )) as ret_row
 from (select ' '||col||' ' splitted
 from t)
 connect by level <= length(splitted)-length(replace(splitted,' ',''))+1
 and instr (splitted, ' ', 1, level+1) - instr (splitted, ' ', 1, level) -1 > 0 order by 1;
3. now run this
select name2,count(*)
the same like above but group by name2, then you will see it

How to find databases registered in recovery catalog!

I want to know how many databases registered in recovery catalog
How can i find it?
Thank you!

Log in as your catalog owner and execute select distinct db_name from dbinc; with this you will see all registered databases , In 11G onwards as virtual catalog owner you will only see the databases on which you have been granted access.
