ApEx 4.2 - Table query on a report

Similar Questions

• the SQL for apex 4.2 with 'apex_item.text' region report renders incorrectly

  In the APEX 4.2 page, I created region "report data.
  
  Type = "SQl query".
  
  'User interface'-> 'Template '=' area of reports.
  
  "Area Source 'is' select apex_item.text (1, '111') as double c1".
  The select query is actually much more complex, but generally simplified it is such, that it uses the function "select apex_item.text" construction HTML textfield.
  
  If I run in query Sql Developer
  

  select apex_item.text(1, '111') as c1 from dual;

  Then it results in:

  <input type="text" name="f01" size="20" maxlength="2000" value="111"  />

  But in APEX 4.2 the report is rendered thus:
  

  <td  headers="c1">&lt ;input type=&quot ;text&quot ; name=&quot;f01&quot; size=&quot;20&quot; maxlength=&quot;2000&quot; value=&quot;111&quot;  /&gt ;</td>

  ("for this forum poster correctly I had to put extra spaces between ' ' & gt ' and ';' and so on)
  
  And APEX 4.2 shows ugly html inside the cell of report/slot for me, showing characters/symbols ">". The reason is that APEX source HTML of the page has no symbol ">" but has "' & gt; '."
  
  The APEX 3 I have a similar query works fine, without such an anomaly.
  
  What attribute should I change in APEX 4.2 region to display the result of my query as needed?
  
  I need this 'apex_item.text' function, I can't remove it.

• Q: very simple you can add more than 1 table to a Word report? -If Yes, how

  Hi all

  As described in the topic, is it possible to add more than 1 table to a Word report?

  Very simply, I have some test data in a table and added to my report with the addition of the report table vi.

  I have the same thing again to send data to a different table which I would like to insert in my report in table form. I placed a second addition table report vi directly after the previous vi, but it doesn't work.

  ... Am I stupid? or this function is only meant to be used at the same time? Maybe I need an another vi after adding table vi before you can add another?

  Feel free to enlighten me because I am confused,

  Thank you!

  Change the width of two column Table add to Report.vi from 10 to 1. Setting the value to 10 (unit are inches) will throw an error.

  Many queries take less time the second time you run them. After the first performance, there may be many, if not all, lines in the buffer cache. Then the second round will not make any or all e/s physical but will obtain data from the buffer cache.

  Also, you haven't checked that the MV was even used for the second run.

  Drop the MV and make the query several times and means of the time. Then create the MV and do the same thing.

• Unique problem with selction on the table (Query Page)

  Unique problem with selction on the table (Query Page)
  
  I have a VO data Bulletin Board, with a transitional attribute for selction unique column.
  My requirement is that I need to identify the line that was selected in the table.
  
  I associated with fireAction singleSelection column, such that whenever the user selects the line
  I'm looking for that VO using some rowIterator.
  But when running the loop of the transient VO that is mapped to the singleSelection variable is the show as "n" / NUll
  for all the lines...
  
  So how do you identify the selected line in singleSelection to a table.
  
  -Sasi

  In the property inspector of the element for which you've put firePartialAction, you can find a property named "parameters". That mention primary key as your setting.

  You can get the arameter using pageContext.getparameter ();

• Forms and reports on apex 4.0 table

  Hi all
  
  I have installed 4 Apex in RDBMS 11R2 based on Linux, created a workspace, all went well.
  Now when I try to create a simple form and a report based on a table that I am running into problems.
  (I think I do something wrong, because I don't see any similar thread) Here's what I did:
  
  Table: master_hierarchy_level
  LEVEL_ID NUMBER (8.0) No.
  LEVEL_NAME VARCHAR2 (20 CHAR) NO.
  Yes LEVEL_DESC VARCHAR2 (320 BYTES)
  CREATION_DATE TIMESTAMP (0) WITH ZONE No.
  CREATED_BY VARCHAR2 (20 CHAR) NO.
  UPDATE_DATE TIMESTAMP (0) WITH ZONE Yes
  UPDATED_BY VARCHAR2 (20 CHAR) Yes
  VALID_FROM TIMESTAMP (0) WITH ZONE No.
  VALID_UNTIL TIMESTAMP (0) WITH ZONE Yes
  
  After you have created the 2 pages, I have change the data fields to the form page to display by default the date and time:
  one) mask format: DD-MON-YYYY HH24:MI:SS
  (b) source Type: SQL query...
  (c) value source: SELECT TO_CHAR(SYSDATE, 'DD-MON-YYYY HH24:MI:SS') FROM dual;
  
  For the created_by and updated_by fields, I did:
  (a) source Type: PL/SQL Expression or a function...
  (b) value source: APP_USER
  
  Nothing else, when I run the report and click on the button create, all goes well after having filled in the required fields and pushing the record button I get following error:
  
  ORA-01400: cannot insert NULL into ("MASTERDB_V01". "" "" MASTER_HIERARCHY_LEVEL '. "" CREATION_DATE')
  Error failed to process row in the MASTER_HIERARCHY_LEVEL table.
  
  I tried to find out why now already several hours and have no nails more to search,.
  can someone give me a hint :-)?
  
  Thanks in advance, Olaf

  OLAF,

  When you have changed the value of type/source of your date fields you deleted the connection of the page item in the database table/column.

  In other words APEX doesn't know that your date fields must be stored in the table.

  Please define the type of source to database column and use the default setting to set a default value for the date fields.

  brgds,
  Peter

• Apex 4.2, display image in the report.

  Hi all

  I'm a noob here Apex. I came across some problems with image display in a report. When I tried to have a report on a form of simple image download, it works perfectly with dbms_lob.getlength("IMAGEFILE") 'IMAGEFILE', workaround. Interactive report based on my table structure, already established the appropriate sections in report page for make my life easy.

  Problem when I tried to create the report of a SQL query combining three tables (Image3, CustomerDB, PATMAN2). The report now generates a page where I can not have any selection of BLOB. The textual part, appears perfectly.  I think my sql code is fine, but my generation of form Apex is faulty, but I need help to solve the problems.

  -----------------

  Here's the SQL code of the image gallery that works very well.

  ------------------

  Select "PUBLICATION_NO."

  "FILENNAME,"

  DBMS_LOB. GetLength ("IMAGEFILE") "IMAGEFILE",.

  "MIME TYPE"

  'PDFNAME '.

  DBMS_LOB. GetLength ("pdflink") "PDFLINK."

  "LASTUPDATED"

  "ID".

  of ' #OWNER # '. " IMAGE3.

  ---------------------

  And here is the one which does not show correctly the BLOB type.

  ---------------------
  

  Select PATMAN2.ID as ID,

  PATMAN2.PA as PA,

  PATMAN2. SUCH as TITLE,

  PATMAN2. OTHERS like the OTHERS,

  PATMAN2. TYPE as the TYPE,

  PATMAN2. PATENT_FAMILY as PATENT_FAMILY,

  CUSTOMERDB.COMPANY_ID as COMPANY_ID,

  PATMAN2. PUBLICATION_NO as PUBLICATION_NO,

  IMAGE3. FILENNAME as FILENNAME,

  DBMS_LOB. GetLength (IMAGEFILE) do IMAGEFILE,

  IMAGE3. PDFNAME as PDFNAME,

  DBMS_LOB. GetLength (pdflink) as PDFLINK,

  IMAGE3. MIMETYPE as MIMETYPE,

  PATMAN2. CUSTOMER_ID as CUSTOMER_ID

  of IMAGE3 IMAGE3.

  CUSTOMERDB CUSTOMERDB,

  PATMAN2 PATMAN2

  where PATMAN2. CUSTOMER_ID = CUSTOMERDB. CUSTOMER_ID

  and PATMAN2. PUBLICATION_NO = IMAGE3. PUBLICATION_NO (+)

  Sorry, no idea what you mean by that.

  Problem when I tried to create the report of a SQL query combining three tables (Image3, CustomerDB, PATMAN2). The report now generates a page where I can not have any selection of BLOB.

  Still, it is far from clear what you mean by "that the report now generates a page where I can't have no matter what selection for BLOB".

  where PATMAN2. CUSTOMER_ID = CUSTOMERDB. CUSTOMER_ID

  and PATMAN2. PUBLICATION_NO = IMAGE3. PUBLICATION_NO (+)

  Did you specify IMAGE DOWNLOAD and BLOB format masks for the IMAGEFILE and PDFLINK columns? Select "BLOB" in the column of the number/Date Format attribute, then fill the section attributes of Blob column as requires it.

  CONNECT BY PRIOR employee_id = manager_id

  Brothers and SŒURS of ORDER BY last_name;

  The output was as below:

• APEX in a table, add 3 default empty lines

  Hello

  I created a tabular presentation on my APEX page.

  Whenever he has some data in the table, it is displayed as below:

  I have to add 3 empty rows by default to the same when the first page load.

  In the dynamic actions, I tried to add a Java Script that add 3 blank lines by default on the page load event.

  JavaScript:apex.widget.Tabular.AddRow(); -This text is written by three times.

  However, the problem is when the page is loaded 2nd, 3rd time whenever 3 more empty lines gets added to the tab.

  I just WAN t 3 fault lines added only the first time when the page loads.

  Help please..!

  

  Hi David,

  Step 1:

  Create branch on the Page that deals

  Type: Branch to the page or URL

  Branch point: present now (after calculation, Validation and treatment)

  Target type: Application Page

  Page: same number of pages / / assume that you create the branch on page 2 and then give 2.

  for example:

  Page: 2

  Application: APPLY_REQ / / here you can write the query that you want to pass after clicking on the button apply.

  Step 2: Change your dynamic action and put this request in the part of the State as suggested in previous post

  Change the dynamic Action

  Conditional - > select "ask!" = Expression1.

  Under Expression1-> APPLY_REQ

  If you still not able to solve so please create the sample on apex.oracle.com?

  and share the workspace name credentials and connect with the name of the application.

  that won't be easy for us to solve your problem.

• Table of different status report

  Hello

  I need my report to show two situations in table form. A part of the table should show only the rows where inside the table database STATUS is 'Success' First table shows a few columns:

  Number_ID, name, surname, sex, etc...

  If there is a line with error in the STATUS column inside the table, second output table of report must show that, but only with the columns first name, last name and Message.

  Now, I had this arranged with GROUP BY, so that the word inside its group by STATUS, then table is divided into two parts, the first "success" and then if errors exist - lines with ERROR are grouped in the "second table". But this is not good, because both sides of table will have the same columns. For example, for the ERROR lines - Number_ID should not shown because these lines are not because they do not have spend in another table.

  I also think it would be good to show only what exists, the so no lines/table error if there is no error lines in the table.

  I know that I can show the conditional regions, as table based on <? If: >

  But I do not know how to implement this to display the output I want.

  I extract data from definition of XML data in the document, XML contains the SQL query that selects the lines in elements.

  Any ideas?

• Multi table query with key foreign null.

  Consider the following tables

  create table student (
   id number not null,
   name varchar2(80),
  primary key(id)
  );
  
  create table course(
    id number not null,
    subject varchar2(120),

  create table class(

    primary key(id),
    foreign key(student_id) references student(id),
    foreign key(course_id) references course(id),
    foreign key(class_id) references class(id)
  );
  

  The student may enroll in a course and then a Professor assign to a class, that's why foreign class_id key isn't a constraint not null.

  What I want is to write a query so that the student can see all courses, it is registered for the class, that he has been assigned and the day of the class, but the report should include courses where the student is not assigned to a class again.

  I wrote the following query.

  select
   course.subject,
   class.name,
   class.day
  from
    course,
    class,
    student_course,
    student
  where course.id = student.course_id
  and class.id = student_course.class_id
  and student_course.foititis_id = get_foititis_id
  

  However, I only get the lines where the student_course.class_id is not null.

  I tried various combinations of coalesce, nvl, decode in both the select statement and where statement, but the results where garbage.

  No idea if such a request is possible?

  8. student_course,
  9. Student
  10. where course.id = student.course_id
  11. and class.id = student_course.class_id
  12. and student_course.foititis_id = get_foititis_id

  However, I only get the lines where the student_course.class_id is not null.

  I tried various combinations of coalesce, nvl, decode in both the select statement and where statement, but the results where garbage.

  No idea if such a request is possible? ...

  It's logical.  The condition on line 11

  Class.ID = student_course.class_id

  will not be TRUE is student.course.class_id is null.

  As Someoneelse said, looks like you need an Outer Join.

  Inner joins, as you use above, produce results only when a row in a table has one matching row in another table.

  In this case (as far as I can tell without data sample or results), you want to display the rows in a table with their matching rows When THERE is a MATCHING ROWS, but you want to show each row of the first table in any case, if corresponding lines.  This is an outer join.

• SQL query for the report?

  Hi all
  I have a large table with column:
  the code, street, data_type, credit, debt, saldo, date
  
  I created query as
  
  sum (saldo), code of Select tableA where data_types = 1 and date < ' 201010 "group by code
  
  but cannot develop this request to be in the report as
  
  COLUMN1 COLUMN2 COLUMN3 COLUMN4
  Sum (saldo) - where type = 1 and date = '201201', sum (saldo) where type = 2, sum (saldo) If date = '201205', code
  
  What is the best solution for sums of report for diferent data_types on a single line with just one code per lines?
  concerning

  You can use CASE what

   
  
  sum(saldo) -, sum(saldo) where type=2, sum(saldo) where date ='201205' , code
  
  select code,
    sum(case when type=1 and date = '201201' then saldo else 0 end) AS COLUMN1,
    sum(case when type=2 then saldo else 0 end) AS COLUMN2,
    sum(case when  date ='201205' then saldo else 0 end) AS COLUMN3,
    sum(saldo)
   from tableA
  group by code

• Access APEX_APPLICATION. G_F01 in a SQL query for a report

  APEX 4.0.2.00.07
  
  I have a standard report with check boxes. The SQL along the lines of:

  SELECT APEX_ITEM.CHECKBOX(1,empno,'CHECKED') " ",
         ename,
         job
  FROM   emp

  Then I have another report below, I want to drive based on the items checked in the first report. I know that the values of the checkbox in the APEX_APPLICATION. Collection of G_F01. Normally, these are accessible using pl/sql such as:

  FOR I in 1..APEX_APPLICATION.G_F01.COUNT LOOP
      DELETE FROM emp WHERE empno = to_number(APEX_APPLICATION.G_F01(i));
  END LOOP;

  But is it possible that I can access the collection from the sql for my second report.
  
  that is, I want my sql to be something like:

  SELECT empno, day_of_service
  FROM   emp_timesheet
  WHERE emp_no in <get access to the collection here>

  I was hoping that the collection box would be available in the APEX_COLLECTIONS view, but it doesn't seem to be there.
  
  Thank you
  John

  John,

  If the goal is to keep the values checked for another treatment then you could add them to a collection yourself.

  create a process on your page that looks like this:
  This will create your collection if not exist or don't delete everything currently in it if it exists and then insert your new selections.

  DECLARE
     l_col_name varchar2(30) := 'EMP_SELECTED';
  BEGIN
      apex_collection.create_or_truncate_collection(l_col_name);
      FOR I in 1..APEX_APPLICATION.G_F01.COUNT LOOP
          apex_collection.add_member(
              l_col_name,
              to_number(APEX_APPLICATION.G_F01(i))
          );
      END LOOP;
  END;
  

  your second question might look like this:

  SELECT empno, day_of_service
    FROM emp_timesheet
   WHERE empno in (select C001 empno
                     from apex_collections ac
                    where ac.collection_name = 'EMP_SELECTED')
  

  Edit
  Some people choose to create a view of some collection queries ontop that will be repeated throughout the application so we can just

  create view selected_emps as
  select C001 empno
    from apex_collections ac
   where ac.collection_name = 'EMP_SELECTED'   
  

  and your new query will look like:

  SELECT empno, day_of_service
    FROM emp_timesheet
   WHERE empno in (select empno
                     from selected_emps)
  

  See you soon,.
