• JavaScript Confirm box depends on the results of query

  Hello
  
  I use Apex version 3.2.1 and I'm looking for a way to do the following, any help much appreciated:
  
  A javascript confirm will appear when the user sends a page if the result of a query returns something, the query should look like this...
  
  SELECT * FROM LINKEDPROJECTS
  WHERE ENV_ID =: P18_ENV_ID
  AND ID_COMP =: P18_COMP_ID
  AND DATE_FROM < = to_date (: P18_DATE_TO, 'DD-MON-YY')
  AND DATE_TO > = to_date (: P18_DATE_FROM, 'DD-MON-YY')
  
  If it returns no data page will present as usual, if it does not return the data from the confirmation box will appear, and the message will be also the result of a query-driven.
  
  If the message would be something like...
  
  Project (s) + "select the NAME OF PROJECTS WHERE ID IN (SELECT PROJ_ID FROM LINKEDPROJECTS WHERE ENV_ID =: P18_ENV_ID +)"
  + AND IDENTIFIANT_COMPOSANT =: P18_COMP_ID +.
  + AND DATE_FROM < = to_date(:P18_DATE_TO, 'DD-MON-YY') +.
  + AND DATE_TO > = to_date (: P18_DATE_FROM, ' MON-JJ-AA "") "+ have this environment for the dates you selected.  Do you want to continue with the reservation?
  
  By selecting Yes submits the page, select no hands it to the page.

  Had this work now, if it can help someone else out there that's what looked like my javascript in the end...

  Hello

  Single quotes used for CLERKS are very probably the origin of the problem.
  C:\Documents and Settings\ITL > exp scott/tiger@orcl tables = (emp) QUERY ='"WHERE deptno 10 > and job!" = 'CLERK' ' ' LOG = log011.log FILE = Exp01.dmp.

  try to replace this
  C:\Documents and Settings\ITL > exp scott/tiger@orcl tables = (emp) QUERY ='"WHERE deptno 10 > and job!" = "REGISTRAR" "' LOG = log011.log FILE = Exp01.dmp.

  Two single quotes (no quotes) to place an apostrophe for CLERK.

• Want to Elimate 'SYS. ODCIVARCHAR2LIST"by the result of query

  Hello
  
  Oracle Version installed is 11.0.2r6. I have a dummy table with data as below:
  
  STID ADDRESS Type_de_fichier
  -------- ------------------ ----------------
  SALES of ABC 9927 has 0
  TRANSFER of XYZ 9927 b 0
  TRANSFER of ABC 9927 has 0
  TRANSFER of XYZ 9927 b 0
  
  I want that the output voltage:
  
  STID ADDRESS Type_de_fichier
  -------- ------------------ ----------------
  9927-0 ABC SALES, TRANSFER
  TRANSFER of XYZ 9927 b 0
  
  I used 2 methods to achieve the same result, but face some problems.
  
  Method 1:
  --------------
  SELECT STID, ADDRESS, LISTAGG (File_Type, ',') within THE GROUP (ORDER BY Type_de_fichier) AS file_type
  MODELING
  STID GROUP, ADDRESS;
  
  I got the output as:
  
  STID ADDRESS Type_de_fichier
  -------- ------------------ ----------------
  9927-0 ABC SALES, TRANSFER
  9927b 0 XYZ, TRANSFER
  
  Method 2:
  -------------
  SELECT STID,
  ADDRESS,
  CAST (COLLECT (SEPARATE File_Type) AS SYS. ODCIVARCHAR2LIST) AS File_Type
  FROM (SELECT STID, ADDRESS, MODEL Type_de_fichier)
  STID GROUP, ADDRESS;
  
  I got the output as:
  
  STID ADDRESS Type_de_fichier
  -------- ------------------ ----------------
  9927-0 ABC SYS. ODCIVARCHAR2LIST (SALES, TRANSFER)
  9927b 0 XYZ SYS. ODCIVARCHAR2LIST (TRANSFER)
  
  Same method 2 gave good result which I like, "SYS. ODCIVARCHAR2LIST"is coming as a prefix in the result. I tried to use the replace, but it does not work. I tried to use the "wm_concat" method, but it does not work.
  
  Can someone help me please to get there? I want a simple Select statement, not the functions/procedures etc.
  
  Thank you
  Stéphane.

  And what about:

  SELECT STID, ADDRESS, LISTAGG(File_Type, ',') WITHIN GROUP (ORDER BY File_Type) AS file_type
  FROM (
       SELECT DISTINCT STID, ADDRESS, File_Type
       FROM DUMMY
       )
  GROUP BY STID, ADDRESS;
  

• To access the results of query XML MSSQL

  
  
  I use MS SQL Server with a query of the form: SELECT * FROM tablename FOR XML AUTO [, XMLDATA]
  (The brackets above to indicate optional use of the XMLDATA option and are not explicit)
  I'm capable of outputting the result in passing the name of the query to CFDUMP so I know that the SQL statement returns the correct information. However, I want to store the XML in a string variable, in the end to go to XMLParse (for example).
  
  How to access the ResultSet? Columns in the table are not relevant in the case of XML output.

  Nevermind, sorted it.

  For anyone interested, the answer is that the query can be serialized to a string via CFWDDX.

  If you do not need to display the dates, the above query can be shortened a little.

  Etbin showed how to get 3 days in response #1, usinng the analytical SUM function totals.  The analytic RANK function, estimated above, which of the totals is higher (or, in the event of a tie, lines 2 or more have the largest number).  Because you cannot nest analytic functions, the analytical SUM function should be called in a separate subquery before calling the analytic RANK function.  Since the analytical functions are calculated after the WHERE clause has been applied, you cannot use in a WHERE clause. That is why RANK is compuuted in another subquery and its results used in the WHERE clause of the main query.

• Automate the name of file with form data

  We seek to use Adobe sign for our forms of active release in our office - everything is going well so far, I was just wonder if there is a way to change the file name of the completed form using the form data?

  For example, once the form has been signed, it is just registered as 'agree active form' - However, before signing, we find the serial number of the asset and the user, it is associated with. Is it possible for the file name automatically and then say "Okay - USER - active form SERIES" or even simply the username if possible?

  Thanks in advance.

  Sorry, it is not clear what you want.

  If the table contains only "Ben", then you can get the output above using a query like this:

  SELECT name. '' my name is' ' AS name_plus

  FROM tbl_name;

  I hope that answers your question.

  Consider the following tables

  create table student (

   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?

  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.
