• Using PL/SQL function

  I need expert advice on writing a function of this requirement.
  Guess it's my table named, SEARCH
  
  STORE_ID PART_ID PART_NAM
  
  1 100 "AAA".
  1 200 'BBB '.
  1 300 "CCC".
  2 900 'MMM '.
  OF 2 800 'YYY '.
  3 400 'DDD '.
  3 200 'BBB '.
  3 100 "AAA".
  
  I have only 3 stores separate with the ID 1, 2 and 3
  
  I need to write a function such that I'll pass store_id and part_id and it should return the part_name.
  
  my_fun (1,100) returns "AAA".
  
  But there are chances that store_id went the calling procedure is incorrect, something like this... my_fun (4,900), there is no store with ID = 4. In this case, I need to watch the part_id assuming store_id is 2. If found return to part_name, if no data, assume that the base id is 3 and get the part_name, another newspaper error.
  
  My_Func (4,900) should return "MMM", and
  My_Func (5,400) should return "DDD".
  
  Well, I wrote the work function, but it is ugly. Everything I do is every time, I take the County.
  
  SELECT count (1)
  in v_count
  SEARCH
  where part_id = p_part_id
  and store_id = p_store_id;
  
  County IF > 1 - indicates the existence of a record
  
  THEN
  
  SELECT part_nam
  in v_part_name
  SEARCH
  where part_id = p_part_id
  and store_id = p_store_id;
  
  RETURN part_nam;
  
  ON THE OTHER
  
  SELECT count (1)
  in v_count_2
  SEARCH
  where part_id = p_part_id
  and store_id = * 2 *;
  
  IF v_count_2 is > 1 - indicates the existence of the piece in store - 2
  
  again use select it in to get the part_nam else
  
  SELECT part_nam
  in v_part_name
  SEARCH
  where part_id = p_part_id
  and store_id = * 3 *;
  
  
  While working, he looks very ugly. I don't know there's a better way to do this. Can anyone help?
  
  Thank you

  So, everything you need inside a function would be something like...

  select coalesce(t1.part_nam, t2.part_nam, t3.part_nam, 'Not Found') as part_nam
  into v_result
  from (select p_store_id as store_id, p_part_id as part_id from dual) r
       left outer join lookup t3 on (t3.store_id = 3 and t3.part_id = r.part_id)
       left outer join lookup t2 on (t2.store_id = 2 and t2.part_id = r.part_id)
       left outer join lookup t1 on (t1.store_id = r.store_id and t1.part_id = r.part_id)
  

  where p_store_id and p_part_id are the parameters passed to the function and the v_result is a variable to the output of the query to

  You can then test 'Not found' in your code and do whatever logging you must make as appropriate and take again the result of the function.

• Can I use the SQL function while setting of passage in the links?

  4.2.1
  
  Hello
  
  I have a report that is a hypertext link (using the column binding feature standard apex) to another page. One of the parameters (columns) I spend is a varchar column with & values. Now, there is a restriction on the passage, & in the apex in 4.2.1. I was wondering if we can use something as a replacement (COLUMN1 # #, ' & ','-')) in the connection settings?
  
  Unfortunately, the column does not have an equivalent id that can be used.
  
  All of the suggestions.
  
  Thank you

  You can create another field in your query that might contain the value "prepared" - you set this to be a hidden column in the report definition and use it in the URL.

• assign a value to a text element using the PL/SQL function body

  Hello

  Your body of the function doesn't return anything.
  Maybe it works

  declare
    l_name varchar2(100);
  begin
    if v('P3_CREHIDD') = 'Edit' then
      select ename
      into l_name

• APEX shortcuts using the source of the body of the PL/SQL function

  Hi all
  
  Recently, I came across the feature of "Shortcuts" in the "Shared components" section of the APEX and thought great, somewhere to set the common/standard items once, then use these several times in different pages of my application.
  
  This seemed to work correctly when you use the 'Source' of "HTML Text" or "HTML text with special characters escaped", but then I wanted to explore the use of the "Body of the PL/SQL function" option to create a more dynamic shortcut/variable on the base.
  
  This is where I came across a particular problem in the APEX (Version 3.2.1.00.10 on GR 11, 2 on Oracle Enterprise Linux). When I set my shortcut, and then perform a reference to my shortcut (using "MY_SHORTCUT") in an area of a page, the value of shortcut is back, but is added with the reference variable (ie. the 'MY_SHORTCUT' chain).
  
  For simplicity, my example looks like this (of course, my real world example is a bit more complicated, but this example produces the same error):
  (a) I define my shortcut called "MY_SHORTCUT" and using the body of the PL/SQL function under "Source Type", define my procedure as "htp.p(:USER)."
  (b) I then create a new page (basic HTML page), and a new region of the 'type'-> 'HTML Text (with shortcuts).
  (c) in the "Source region", I define my shortcut like - "MY_SHORTCUT".
  (d) I apply changes and then run the page.
  
  I'll be back will be name of the current user with "MY_SHORTCUT" appended/added immediately after the user name - for example. the string:-' BRAD «MY_SHORTCUT»»
  
  Question is - how to stop the shortcut/reference text "MY_SHORTCUT" to be added to the variable you want to see the and thereafter on your page? I am just wanting the variable, NOT the reference for the shortcut.  I do something wrong using the HTP package, and if yes, what should I use?
  
  If "MY_SHORTCUT" is defined as "HTML text with special characters escaped" (where I can refer to elements of application using the syntax '& USER.') so that everything works correctly. My reason for using the PL/SQL is to generate a more dynamic output variable, based on elements of application throughout the entire application - and of course the use of shortcuts to minimize coding and duplication.
  
  
  Thanks in advance,
  Brad

• PL/SQL functions as LOV to use in another display object

  Hello

  We had a custom search to extract data from a display object and the data displayed as a Table of ADF. Now, there are few requests for searches on this report. Go see criteria and Panel request if we allow saved search. But the fields used in the research are going through a lot of logic and thus the PL/SQL functions are implemented. We used to call these functions and lists separated by commas and then divided the list into individual elements and put in the component "select options".

  The value (String) returned by the pl/sql function is something like - APAC, EMEA, NORTH AMERICA, FDA

  I am creating a LOV based on SQL-query "Select getRegions() from dual;

  Now, I want the list separated by commas to divide so that I could use this LOV in an another view and try the display criteria and saved searches.

  I tried to assign as LOV just to check and the criteria drop-down view for region displays same value as single element - "APAC, EMEA, NORTH AMERICA, LAD."

  I want it to be 4 separate - elements

  APAC

  EMEA

  NORTH AMERICA

  DVL

  Is there anyway to achieve this?

  Or better is at - it another way to do this (maybe I'm wrong)

  Thank you.

  JDev: 11.1.2.4

  Instead of a programmatic VO of PL/SQL, I found sometimes easier to write PL/SQL functions that return a table - need to CREATE a TYPE for the data items to be returned and a TYPE of TABLE IMBRIQUE tabular form of the first kind.  The function returns the type of table, and can even be a PIPElined table function.  Then I create a VO with the following text:

  SELECT * from TABLE (my_function_returning_table)

  The function can even take parameters, which you fill with variable BIND your VO.

• SQL using the analytic function

  
  Hi all

  I want a help in the creation of my SQL query to retrieve the data described below:

  I have a test of sample table containing data as below:

  State ID Desc

  MICHAEL 1 T1

  ACTIVE 2 T2

  T3 3 SUCCESS

  DISABLE THE T4 4

  The thing I want to do is to select all the lines with an ACTIVE status in the table but is there is no ACTIVE status, my request will give me the last line with MICHAEL status.

  I can do this in a single request by using the analytical function for example, if yes can yiu help me on the request of unpacking.

  Kind regards

  Raluce

  Something like that?

  I had to fix it.

  with testdata until)
  Select 1 id, "T1" dsc "DISABLED" status of Union double all the
  Select 2 id, 'T2' dsc, the status "ACTIVE" of all the double union
  Select id 3, "T3" dsc, the status of 'SUCCESS' of all the double union
  Select 4 id, "T4" dsc "DISABLED" status of double
  )

  Select
  ID
  dsc
  status
  of testdata
  where
  status =
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then 'ACTIVE '.
  Another 'DISABLED '.
  end
  and)
  ID in (select id from testdata where status = ' ACTIVE')
  or
  ID = (select max (id) in testdata when status = 'DISABLED')
  )

  STATE ID DSC

  '2' 'T2' 'ACTIVE '.

  Maybe it's more efficient

  Select
  ID
  dsc
  status
  of testdata
  where
  status =
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then 'ACTIVE '.
  Another 'DISABLED '.
  end
  and
  ID =)
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then id
  on the other
  (select max (id) in testdata when status = 'DISABLED')
  end
  )

• Use of the function of group in orcl:query sql - database - urgent

  All,
  
  Version: 10.1.3.4
  Two requirements for me:
  1. I want to use the sum function in orcl:query - database. How to use it?
  
  For ex: I tried the following
  
  < xsl: value-of select ='orcl:query - database ("select sum of emp", false (), false (), "jdbc/DB1")'/ >
  I got the following error
  oracle.xml.sql.OracleXMLSQLException: character ')' is not allowed in an XML tag name.
  When I tried without the sum function, it works fine
  2. I used the same table, but without the sum works as below
  
  < xsl: value-of select ='orcl:query - database ("select emp salary", false (), false (), "jdbc/DB1")'/ >
  This time, it returns the first salary employees! I don't understand this logic. I expected, either the query returns all rows, otherwise it throws the error, but none of them were real!
  
  Can pls someone explain what behavior? I want your answer to both queries!
  
  I am currently in a project where I work in the same scenario, so guru of let me know as soon as POSSIBLE.
  
  Thank you

  No - this 'thing' you got is a hidden type of SQL Oracle automatically created to match the type of PL/SQL, that you used. SQL can only work with the SQL types defined at the schema level. But for functions PIPELINED Oracle allows you to specify the types of PL/SQL and it will create SQL HIDDEN types to make it work.

  A pipeline function should be treated as a table. You must use the SCOREBOARD operator

  Select * from table (myFunction);

  Try this simple example

  -type to match record emp

  create or replace type emp_scalar_type as an object

  (EMPNO NUMBER 4,

  ENAME VARCHAR2 (10),

  USE VARCHAR2 (9).

  MGR NUMBER 4,

  HIREDATE DATE,

  NUMBER OF SAL (7, 2)

  NUMBER OF COMM (7, 2)

  DEPTNO NUMBER (2)

  )

  /

  -records of the emp table

  create or replace type emp_table_type to table of emp_scalar_type

  /

  -function of pipelined

  create or replace function get_emp (p_deptno number)

  return emp_table_type

  PIPELINED

  as

  TYPE EmpCurTyp IS REF CURSOR RETURN emp % ROWTYPE;

  emp_cv EmpCurTyp;

  l_rec emp % rowtype;

  Start

  Open emp_cv SELECT * from emp where deptno = p_deptno;

  loop

  extract the emp_cv in l_rec;

  When the output (emp_cv % notfound);

  line of conduct (emp_scalar_type (l_rec.empno, LOWER (l_rec.ename),

  l_rec.job, l_rec.mgr, l_rec.hiredate, l_rec.sal, l_rec.comm, l_rec.deptno));

  end loop;

  return;

  end;

  /

  Select * from table (get_emp (20))

  See use of the SCOREBOARD operator?

• Parse the JSON using PL/SQL string

  I created a script that reads data from the Mobile App DB (which is based on MongoDB) of Oracle SQL Developer. The result is the string JSON stored in l_response_text VARCHAR2 (32767);

  The string has the format such as:

  
  

  [{"Postcode":"47100","OutletCode":"128039251","MobileNumber":"0123071303","_createdAt":"2014-11-10 06:12:49.837","_updatedAt":"2014-11-10 06:12:49.837"}, {"Postcode":"32100","OutletCode":"118034251", ..... ]
  
  
  
  
  

  However, I need to analyze this l_response_text such that each table will in his column in a table called appery_test. appery_test table has the same number of columns pairs JSON and in the same order (e.g. name of the first column is 'postal Code')

  I searched and I found most of the results on the analysis of the Oracle in JSON table and not the other way around. I found, however, that link which is somewhat similar to my problem. However, the library suggested in the answer doesn't have an example on how to use it to insert JSON into conventional table using PL/SQL.

  N.B.: I use g 11 and not 12 c. If the functions built by are not available for me.

  Thank you very much

  Sorry, I am a novice in this area too.

  However, it worked for me:

  declare

  l_list json_list;

  l_data CLOB;

  Code postal clob;

  l_val json_value;

  Start

  -json data recovery

  Select the data in l_data from jsons where id = 1;

  l_list: = json_list (l_data);

  I'm looping 1.l_list.count

  l_val: = json_ext.get_json_value (json (l_list.get (i)), 'Postcode');

  DBMS_LOB.CREATETEMPORARY (zip, true, 2);

  json_value.get_string (l_val, postal code);

  Back AFTER using the exception block is fine as long as your code actually REACHED the exception block.

  When there are no errors, then your code will not enter the exception block, but you still NEED to return a value, since it is what functions a function wants to return a value, that's what the functions are made for.

  Spot the differences between the following 3 functions. Understand how they work.

  The first function has only a return in the exception block but runs correctly. Result: error, because the back is missing in the code block.

  The second function has a return in the exception block and one in the block of code and runs correctly. Result: no error, because the return is not missing in the code block.

  The third function has a return in the exception block and one in the block of code and is forced into an error. Result: no error, because the return of the exception handler is used (instead of retriggering of the error, which you would normally do).

• PL/SQL function to calculate the non-working days

  Hello

  I have the following pl/sql function which generates a number of days between two selected dates (i.e. excluding weekends). However, I also need to exclude specific holidays - day of Christmas etc. These holiday dates are stored in a table in our database (11 GR 2) called "HOLIDAY".

  How can I integrate the holidays which is held in the table of holidays in the following query to exclude these dates as well? I know how to write a separate funtion pl/sql for a number of days between two dates using SELECT... BUT I can't work out how to bring together them in a single query.

  Could someone show me how with the pl/sql / dates below please?

  Hello

  the link is on MOSC, not OTN... Here's a copy:

  This function calculates the number of days between two dates, ignoring weekends and holidays (if requested and if the holidays are stored in a table)

  I give an example of table 'public_holiday' with sample data, but users must ensure that their table contains the relevant data (all holidays within the maximum range of use of the service)

  CREATE TABLE public_holiday (calendar_day, DATE, text VARCHAR2 (30));

  FUNCTION to CREATE or REPLACE nb_days (p_date_from IN DATE

  p_date_to DATE by DEFAULT TRUNC (sysdate)

  , p_public_holidays in CHAR DEFAULT 'Y '.

  ) RETURN NUMBER

  Nothing to do with the Muse at all. You have things backwards. If you use a dynamic interface, you work in the API hooks and predefined functions and that he don't just slap on an arbitrary HTML façade. It is simply not how it works.

• Help SQL function

  Hi all

  I have a table which includes

  ID, first_name, last name and date of birth

  I want to retrieve all the records that have the same name and DOB

  for example.

  ID, first_name, last name, DOB

  1 xyz abc 01/01/2012

  hij 2 efg 15/05/2012

  3 xyz abc 01/01/2012

  4 xyz abc 01/01/2012
  

  so in the output of 1, 3 and 4 rows will appear only.

  can someone advise please on the appropriate SQL function

  Thanks in advance

  Hello

  One way is to use the analytical COUNT function:

  WITH got_num_rows AS

  (

  SELECT id, first_name, last_name, dob

  , COUNT (*) OVER (PARTITION BY first name

  last_name

  ,             dob

  ) AS num_rows

  FROM table_x

  )

  SELECT id, first_name, last_name, dob

  OF got_num_rows

  WHERE num_rows > 1

  ;

  The subquery is needed here, because the analytical functions are calculated after the WHERE clause has been applied.  To use the results of an anlytic function in a WHERE clause, you must calculate the function in a subquery, then you can use the results where you want (including the WHERE clause) of a Super query.
