MATH HEAVY - SQL and PLSQL - PROCEDURE/FUNCTION

Hello

I have a chart with lines more million. In this table, I have a lot of members associated with 60-70 facility_names.
Unique index is on CMPNY, FNAME, M_ID MONTHS.

Below, I have some EXAMPLES OF 3 facilities, ADIOS DAOMATO, NADA CAPETOWN and NADA NEW DIAMONDS.

These companies have two different contract.

For example, NADA CAPETOWN & NADA NEW DIAMOND
-As soon as total Amount_1 CDA for a member associated with above facilities will more $2,000 and total Amount_2 passes over $4000, installation gets insurance protection for 90% of the sum, he surpassed in each categories.

In example below, M0001 of NADA CAPETOWN, CDA AMOUNT_1 total more than $2,000 to 1 October 2009 (total $2160), installation gets recoveries of $144 ((2160-2000) * 90%).
Similarly, in November 1, 2009, total of CDA is $2180 and installation gets recoveries of $18 ((2180-2160) * 90%). I subtracted $2160 because installation has already received $144 for having exceeded $160, more than 2000 back on October 1, 2009.

Very similar, total if Amount_2 CDA exceeds 4000, TI $ receives 90% of the amount after $4000. (the calculations are the same as above)
The column of recoveries should summarize recoveries exceed amount_1 and amount_2 per month.

During this time,.

ADIOS DAOMATO has a different contract. When single member of this facility (CDA AMOUNT_1 + AMOUNT_2 CDA) is greater than 5000, the plant recovers 90%.

In the case of sum CDA Member Unique of ADIOS DAOMATO of AMOUNT_1 & AMOUNT_2 (combined) will more than $5,000, then installation gets insurance protection for 90% of the amount it exceeded.
In the example below, total ADIOS DAOMATO CDA exceeds $5,000 in October 1, 2009 by $540 ($11080 total YTD), so installation retrieves ((11080-10000$) * 90%) = $972. After months of November 1, 2009, $40 ($20 + $20) added more than $5,000, so installation recoveres (($5580-5540 $) * 90%) = $36...

* I don't mind saw these two distinct processes. Please note that the calculation of recoveries ($) are by a single member of the installation by month/year, but the result should be to ease a month. So far I have annually. But I really need every month for financials.*

Purpose: I need to know what level of insurance protection the installation receives monthly.
For the duration of the contract 1 the Reisurance Total must be entered in the column "RECOVERIES" (COLLECTIONS of REINSURANCE OF AMOUNT_1 + the RECOVERIES of REINSURANCE OF AMOUNT_2).

For the duration of the contract 2, there is only 1 recovery mode.

As the I mentioned, that's a CALCULATION for a YEAR when the year changes, everything resets all members. *
_ I would greatly appreciate your help. _

I think he might have an error in your example output. I think 3150 is the correct value. The sample data for 2009 and 2010 are the same.

interesting SQL and plsql problem.

The web application has a function to generate reports based on what the user selects, which includes this as the fields to display in the report, what order to display those selected fields, etc.

Now, one of the field called suffix field is need removed the drop-down lists SELECT and ORDER BY. Please advise on how to solve the problem when the suffix record is removed from the database, and how we can increase the index [#] of these later OrderByField?

reportId reportField reportValue
====================
1 orderByField fname [0]
1 orderByField [1] MI
1 lname orderBytField [2]
1 orderByField [3] suffix

lname orderBytField 2 [0]
suffix of orderByField 2 [1]
2 orderByField fname [2]
2 orderByField [3] MI

In the example above, delete suffix will not affect reportId 1, but for reportId 2, if we remove the suffix, how do we record like the following?
lname orderBytField 2 [0]
2 orderByField fname [1]
2 orderByField [2] MI

I am open to any suggestion, using sql and plsql. The database is 9i.

I want to improve my skills in sql and plsql

Hello friends,
I finished the course SQL and PLSQL a few weeks back. Since then I've been hunting for a relevant work for SQL / PLSQL developer.
However I really want to improve my writing of the subprogrammes, build effective SQL queries to become a skilled oracle developer.
My current work is not linked to this use so all my free time to improve my knowledge in this area.
I know the basics of SQL and PLSQL concepts and can write queries simple, subprogrammes, but to become employable, according to me, that I need to learn a lot more.
Please suggest me some good sources be it no books / sites Web, etc. anything that would really help me become a good developer.
I'm desperate to make a career out of Oracle SQL / PLSQL!
Thanks in advance.

Do what most of the experts do... start at the bottom.

Find a job in a junior role (and yes it will be low wages initially) where the company may see your potential and enthusiasm to learn and will give training and let you learn on the job. If you have the skills to do it, then you will learn quickly and prove you are competent and deserve to be promoted to better roles.

When I started (in the same after having a university degree in it), I always had to start at the bottom, in a junior role, on a 3 month temporary contract. Who got so extended that they identified some new work roles that were needed, and then I had to get one of these new jobs, where I got a permanent role. Within 18 months, they had sent me on the training, and I was promoted to a role of DBA/programmer, working alongside other programmers and hardware team to manage database servers... everything just because I had shown the ability, willingness to learn and the professional approach to my work.

Don't think you can just get some training or the qualities of the review, but have no experience and just get into some senior roles or an expert, as most of the companies are wise to such things... they want to know what you have for the roles of the experience.

need to get sql and plsql certifications

Dear Sir
I did the track developer oracle 9i in 2008 and not not taken any which certificate online, but right now I want to get this certificate to provide to my new employer which depends on, could you pls tell me who exact route because I saw the site of oracle certification, but some are for those who already made in the past as a dimming etc but no accreditation for those who have not "taken previously.
All Certifications | Certifications | Oracle
Please advice.
Thank you.

As a general rule, I recommend that candidates continue 1Z0-144: Oracle Database 11g: program PL/SQL rather than the exam 1Z0-147. They are equivalent regarding certification obtained the passage, but 144 is newest and best essay in general. Discuss the two in this article here:

Oracle PL/SQL Developer Certification: 1Z0-147 or 1Z0-144?

Studying the materials, I have compiled links to documents of study of certification secure for a number of reviews of Oracle on my site. Links for 1Z0-047 and 1Z0-144 are:

Updated APEX collection error ORA-04044: procedure, function, package, type
Hi all

I am trying to update the APEX MEMBER of the COLLECTION and encounter errors:

1 error has occurred
ORA-06550: line 9, column 8: PL/SQL: ORA-04044: procedure, function, package or type is not allowed here ORA-06550: line 7, column 3: PL/SQL: statement ignored

The PLSQL code are as below

DECLARE
entire x;
v_date_started VARCHAR2 (255);
v_date_finished VARCHAR2 (255);
BEGIN
SELECT c.seq_id
X
OF APEX_COLLECTION c
WHERE collection_name = "PHASE_COLLECTION."
AND c001 =: P41_MPM_ID
and rownum = 1;
v_date_started: =: P41_DATE_STARTED;
v_date_finished: =: P41_DATE_FINISHED;

APEX_COLLECTION. () UPDATE_MEMBER
p_collection_name = > 'PHASE_COLLECTION '.
, p_seq = > x
, p_c004 = > v_date_started
, P_c005 = > v_date_finished
);
END;

The process will take place after SUBMIT and validation.

The code I used to add a colletion APEX will work perfectly and is as below

-Initialization Collection PHASE_COLLECTION
BEGIN
IF THIS ISN'T APEX_COLLECTION. COLLECTION_EXISTS('PHASE_COLLECTION') THEN
APEX_COLLECTION. CREATE_COLLECTION ('PHASE_COLLECTION');
ON THE OTHER
APEX_COLLECTION. TRUNCATE_COLLECTION ('PHASE_COLLECTION');
END IF;
-Add members to the COLLECTION PHASE of table PHASE_MEMBERSHIP
IF: P41_MPM_ENG_ID IS NOT NULL THEN
FOR x IN (SELECT mpm_id, mpm_eng_id, phase_number, date_started, date_finished, date_created
OF phase_membership
WHERE mpm_eng_id =: P41_MPM_ENG_ID
AND active = 1
ORDER BY date_created)
LOOP
APEX_COLLECTION. ADD_MEMBER
(p_collection_name = > 'PHASE_COLLECTION')
, p_c001 = > x.MPM_ID
, p_c002 = > x.MPM_ENG_ID
, p_c003 = > x.PHASE_NUMBER
, p_c004 = > x.DATE_STARTED
, p_c005 = > x.DATE_FINISHED
, p_c006 = > x.DATE_CREATED

);
END LOOP;
END IF;
EXCEPTION
WHILE OTHERS THEN
Logger.Error (p_message_text = > SQLERRM)
, p_message_code = > SQLCODE
, p_stack_trace = > dbms_utility.format_error_backtrace
);
LIFT;
END;

What I tried to use APEX_COLLETION to check the overlap between the date_range.
The requirement is just to display a warning if the user adds a record to the new phase or update record of current phase may overlap between the order of phase together.
Table PHASE_MEMBERSHIP script is

CREATE TABLE 'PHASE_MEMBERSHIP '.
(
ACTIVATE THE "MPM_ID" NUMBER NOT NULL,
ACTIVATE THE "MPM_ENG_ID" NUMBER NOT NULL,
ACTIVATE THE "PHASE_NUMBER" NUMBER (2.0) NOT NULL,
"DATE_STARTED" DATE NOT NULL ACTIVATE.
DATE OF THE "DATE_FINISHED."
'NOTES' VARCHAR2 (2000 BYTE),
'DATE_CREATED' DATE NOT NULL ACTIVATE.
ACTIVATE THE 'CREATED_BY' VARCHAR2 (20 BYTE) NOT NULL,
NUMBER (2.0) 'ACTIVE' DEFAULT 1 ACTIVATE NOT NULL)

So, basically, I want to fill the documents associated with a particular to a collection of APEX called PHASE_COLLECTION MPM_ENG_ID.
Then when the user specify date_started and date_finished, it will update/insert the APEX collection first.
Then the rank based on audit collection date
http://www.Oracle-base.com/articles/Misc/overlapping-date-ranges.php
then display the warning to ask the user to confirm message.

But then I'm stuck at the step of updating COLLECTION of APEX.

If anyone has any ideas on what is wrong, please help.

Thanks in advance.

Ann
Your syntx error line number should give you the trick - it is not a member of the update, rather the SQL - you are referring to apex_collection, not apex_collections view dictionary.

SQL and BI

Hello Experts;
I used some tools like Microstrategy bi, however it is still not comparable to a coding in SQL, PL/SQL, which gives a lot of flexibility, transparency, etc. So, how is it I always get customers pushing to have all of the BI process done on BI tools. Why SQL and PL/SQL, not at the forefront instead. I know that the graphical side of things put it at a disadvantage, but beside that I'm still why a little distraught.

SQL and PLSQL can scare companies, many see a black magic (which, in some respects, can be), and it is not something that many customers feel able to learn or even tend to. On the face of things, this may seem complicated and used wrongly, can cause MAJOR problems with buinesses (poor performance, use excessive resources that affect other sessions). Many have invested time in getting to know point and click graphical tools that can get results without feeling lost and confused by SQL, they prefer.

However, as you rightly remember, nothing can replace SQL or PL/SQL.

I suppose that the element of fear is a bit like why a lot of people using MS Paint to edit an image, many feel uncomfortable with it, he can do the basics, but not much, and they'll settle for that, but you could do much more with Photoshop - it's simply too scary to learn properly for most of the people so that they avoid it - they stick to what is simple and familiar.

Procedure or the view to return the list and uses inline functions?
I have read about this for a while and do not know what is the easiest way to move forward. I need to execute a sql select statement that calculates some of the columns using the functions I wrote. Run the sql and functions within a procedure or a view would be nice, depending on what is more simple.

With sql server you can return the result of a statement select a procedure. You can also include custom online functions.

Say I wrote a fnEvalIsNumber function that returns 1 or 0 if the parameter passed in a certain number or not.

Say I created a table named t_values with a single column, varchar2, containing values such as "Merced" and "Pixie" and 452.

I want to be able to call a proc or view that returns a list of list this:

Value IsNum
Merced 0
Pixie 0
1 452

Fairly basic but my reading here only took me something like a simple solution. I hope that the news that I had are not for some comment. Oracle 10g.

SQL VS PLSQL privileges and subsidies
Hi all

Is there a difference in the privileges of how are handled in SQL a PLSQL? I have a user who can choose a SQL table, but in plsql, the same query reports "table or view does not exist. Later, the same thing happened with another user who was DBA. The user can query the view v$ session, but cannot do PLSQL procedure.
Why is this?

DB is 10.2.0.2
It seems that you access through ROLES and not run like auser. If access to objects of a procedure you need direct rights. You can check if you have rights through roles as follows

SQL > role the value none;

SQL > "you want to test to see if it'll work in a declaration procedure.

If you select in SQL more with none of the roles you can do it in a procedure. If you can't, you must have the privilege to a role, you must have this privilege granted directly to you.

Thank you

The display of an image defined in an external PLSQL procedure that renders the code HTML and called in a region of the APEX

I have an external PLSQL procedure that dynamically creates a report out of the HTML tags that I then called an anonymous block APEX PLSQL. I'm making bad images with the following code:
in the external procedure. How do you get around that? (NOTE: the procedure is too big to store directly in the APEX)

....

' < style td = "width: auto;" "padding: 0px 5px 0px ' > '. spc_rec. SPC_VIABILITY_STATUS. "< table > ' |

"< style td =" width: auto; " text-align: left; "padding: 0px 5px 0px" > ' | spc_rec. SPC_VIABILITY_REASON. "< table > ' |

TD > < img src = "" #IMAGE_PREFIX #check2.gif "alt =" "/ > < table > '"

....

Thanks in advance

PaulP

Hi Paul,.

You can use the global variable of the APEX package below to get the image prefix in pl/sql. Of course, your procedure should be in APEX, schema analysis application.

APEX_APPLICATION. G_IMAGE_PREFIX

Master-detail functionality between the regions of PL/SQL and IR possible?

4.2.1
THM 2
Hi all
We have two regions in a page. The upper region is a region of PL/SQL that lists the 5 best wages by Dept. This was not done using traditional reports because management wanted a "dashboard" as the look and feel that is already existing and what is happening in that it is a pl/sql block that has the sliders and the necessary HTML, CSS in there.
Below that is an IR when the user clicks on the dept of region of PL/SQL, it will refresh the IR below to display all employees in this Department
Top of the page shows region of PL/SQL
EMP name Dept wage
Emp1 10 10000
EMP2 10 950
Emp3 20 800
The Dept field is a hyperlink.
When we click on Dept on this region of PL/SQL
The lower IR should be updated (without submit page)
Output
Emp1 10 10000
EMP2 10 950
It is a kind of master-detail relationship between PL/SQL and Report (Detail) (Master) area Interactive
We can hyperlink in the SQL in pl/sql area, but you wonder how trap line and pass the dept id to the IR and get this region to refresh account?
All suggestions from the experts?
Thank you
Ryan

It is a way to pass the info in connection

Perform the dynamic Action of the link column report

The dynamic action can submit the session state value, and then refresh the IR.

On either by the way, you must create dynamic PL/SQL region to solve this problem, see this

Business event does not trigger the PLSQL procedure... What should do?
We need to call a plsql procedure when the workflow approval GL ended with approval. I thought I could do it by customizing the relevant business event.

We are on EBS 12.1.3 with RDBMS: 11.2.0.3.0.

I see the event oracle.apps.gl.Journals.journal.approve company has been disabled currently. I've enabled and created a subscription for her. Subscription was a PLSQL procedure. Currently, for objective test only thing it does is to insert a row in a table.

Documentation (not sure what value to give the latter. I went with the values below).
Owner: Name of the company
Tag owner: custom Schema

Using query I can see the event company is called when occurs below approval (an added line each time approval that has happened). But I don't see all the lines in the table where to insert a line. What could go wrong? How can I make sure that the procedure was called?

Select * from WF_DEFERRED where corrid'art = 'APPS:oracle.apps.gl.Journals.journal.approve. '

Hello

This OWNER_TAG represents an actual application under license, as "DNF" without the quotes. The business event system will send subscriptions for licensed products.

Also, in order to detect any other possible errors please add a subscription of type error. In this way the BES will catch the error and will notify SYSADMIN of this failure, it's not silent.

Plan does not show the local procedures/functions

Hello
SQLD 4.1
I use the preview to a plsql procedure feature. The procedure provides a local procedure.
In the window structure the local procedure does not at all. Declared variables and cursors in the local procedure are displayed, but as if they where in the main proceedings.
Local procedures and functions should be displayed in the window structure. It would be nice if the declares the variables and cursors of a local proceeding would be arranged in suchs a means, it is visible that they belong to this local procedure, perhaps using an indentation.

Difference of procedure & function

Hi all
After citing some tutorials, I got to know that the difference between the procedure and the function is that the procedure may or may not return a value as the function must return a value to the calling program. Given below is my procedure. & He would compare the lower of the two numbers would be smaller than
create or replace procedure findmin
(
x in number,
there in numbers,
z series
)
is
Start
if(x<y) then
z: = x;
on the other
z: = y;
end if;
end;
declare
c number;
Start
findmin (23,45,c);
dbms_output.put_line (c);
end;
Here's my function even if it does the same thing.
create or replace function findmin_fun
(
x in number,
y number
)
Return number
is
number of z;
Start
if(x<y) then
z: = x;
on the other
z: = y;
end if;
Return z;
end;
declare
Start
dbms_output.put_line (findmin_fun (56,28));
end;
I would like to know under what are all the scenarios of the procedure and function would be used. And also I want to know could do dml as insert, update, and delete operations
If so, could you guys explain me with some examples to expose DML operations on functions

After citing some tutorials, I got to know the difference between the procedure & function is that the procedure may or may not return a value as the function must return a value to the calling program.

Not quite.

A procedure does NOT return a value - it can fill in the parameters OUT or INOUT but which is NOT considered to be "of return values.

A function ALWAYS returns a value that can be null. The only exception is if the function throws an exception.

My procedure is given below. It would be to compare the lower of the two numbers & would mean that smaller

Not quite - the procedure returns NO value. You use it to try to fill one OUT parameter, but it's NOT the same.

I would like to know under what are all the scenarios the procedure & function would be used.

Functions can be used in SQL; procedures cannot be used in SQL.

The functions return a value; procedures of does NOT return a value.

Use the functions when you need to return a value; Use the procedures when you do NOT need to return a value.

It is not possible to list 'all scenarios' for one or the other, because there may be ANY NUMBER of possible scenarios.

And also I want to know could do dml as insert operations, update & delete

What happened when you tried?

The best and fastest, to learn is to actually TRY THINGS. Don't be afraid to break the Oracle by actually writing code and tests of things yourself.

If so, could you guys explain me with some examples to expose DML operations on functions

The Oracle documentation have a LOT of examples of using functions and procedures and include the code of the example.

https://docs.Oracle.com/CD/E11882_01/AppDev.112/e25519/subprograms.htm#CHDBEJGF

The internet has even more examples of code.
