• Join the query in a dynamic list of values query

  I have a join query in a dynamic list of values query. The value does not return a value of text, but rather the value of the ID.
  
  Is it possible to use a join query in a dynamic list of values query?
  
  For example... in the query below, I expect to see ename in the drop-down list, but I see class_emp_id.
  
  Select b.ename d, a.class_emp_id r
  of class_emp a, b of the emp
  where a.class_cat_id =: CURR_CLASS_CAT_ID
  and a.emp_id = b.emp_id
  order by 1
  
  Thank you

  Hey Reid,

  The structure of the pairings/value of the item is incorrect - it should be: item1, item2, etc.: value1, value2, etc, so:

  ' f ? p = & APP_ID.: 50: & SESSION. ": P50_LP_ID, P50_LP_NAME, CURR_CLASS_CAT_ID: #LP_ID #, #LP_NAME #, #CLASS_CAT_ID #"

  I guess that CURR_CLASS_CAT_ID does not use the prefix P50_?

• Join the query

  Hello
  
  I have two tables Employee and EmployeeDetail
  
  Employee table of data as follows:
  EmployeeID
  1
  2
  
  
  EmployeeDetail table of data as follows:
  EmployeeDetailID FkEmployeeID EmployeeName
  1 1 a
  2 2 b
  3 2 b1
  
  
  Note: that in the table EmployeeDetail, detail of the employee was inserted not updated therefore for EmployeeID: exiists there are 2 previous entry in the EmployeeDetail table.
  
  I want to take the latest recordings as
  EmployeeID EmployeeName
  1 a
  2 b1
  
  
  
  I tried following query
  Select Employee.EmployeeID, EmployeeDetail.EmployeeName of the employee
  Left Join EmployeeDetail
  where Employee.EmployeeID = EmployeeDetail.FkEmployeeID
  
  But he has a problem... I do not know how to choose the last disc

  last disk would probably be more EmployeeDetailID, base on this point, as an easy way:

  Select *
  From   Employee e, EmployeeDetail ed
  where e.employee_id = ed.employee_id
      And ed.EmployeeDetailID = (select Max(EmployeeDetailID ) from EmployeeDetail ed2 where ed2.employee_id = e.employee_id)
  

  best solution would be a rank of the analytic function on the partition by but it is more understandable.

• [Help] Join the query from 3 tables

  Hi, I'm new to database. I have a question about joining 3 tables, forgive me for my bad English.
  
  My paintings look like this
  
  Table 1: person (id, firstname, lastname)
  Table 2: AssignPersonAddress (id, personid, addressid, type)
  Table 3: address (id, phone, street, etc.)
  
  I need AssignPersonAddress table, because in my data structure, a person may have more than 1 address and address type must be registered (for example: private, work)
  
  
  I want to do a select query to the State any person with his private phone and work phone, like this.
  NOBODY | PRIVATE | WORK
  
  
  
  Right now my query looks like this
  

  select p.name , a1.tel AS Private, a2.tel AS Work
  from person p, 
  addresse a1 , 
  AssignPersonAddress apd1, 
  AssignPersonAddress  apd2, 
  addresse a2
  
  where p.id  = apd1.person (+)
  and apd1.adresse  = a1.id 
  and apd1.art = 'Private' 
  and p.objectid = apd2.person (+)
  and apd2.adresse  = a2.id 
  and apd2.art = 'Work'

  the problem is that I only get the person who has a private address and the job. But what I want is all anyone no matter if the person has only 1 or 2 address.
  
  As you can see I put the left outer join in where condition, but I always get the wrong result.
  
  
  THX in advance
  
  
  Danny

• Internal XML to the query with join

  I have a CF page that reads an XML file in a query using < cffile > XMLParse and QueryAddrow.

  I then do a QoQ on the result and voila! I have my page.  I hide the query for 8 hours and the XML file is only reread this cache expires.  It works well.

  My problem now is that the file contains data from three tables of database instead of one, so I need to make an inner join on the tables.  But I can't do a t/t with an inner join.

  Does anyone know a way for me to do this?

  Oh, didn't know that.  How about interweaving of QofQ?  Join Query1 and Query2 requests in a new query, then join for 3 statement?

• How do the query select outer join to a report of the APEX

  Hello Ann,.

  Frank has done a very good job. I am also impressed.

  Is in regard to your correction to his question, the problem is on this replacement you did

  last_day(TO_DATE(am.which_month,'MON YYYY'))
  

  AM.which_month is already a date type, and you don't need to convert it to this day.
  Here is the correct way:

  last_day(am.which_month)
  

  There are also sometimes with the data you've posted have no line for this month. So I also added a function NVL to display 0 under avg_days for these cases.

  Here is my corrected query:

  DEFINE startmonth = "Aug 2012";
  DEFINE endmonth   = "Oct 2012";
  WITH  all_months  AS
  (
     SELECT ADD_MONTHS(to_date('&startmonth','MON YYYY'), ROWNUM-1) AS which_month
     ,      ADD_MONTHS(to_date('&startmonth','MON YYYY'), ROWNUM  ) AS next_month
     from all_objects
     where
     rownum <= months_between(to_date('&endmonth','MON YYYY'), add_months(to_date('&startmonth','MON YYYY'), -1))
  )
  SELECT TO_CHAR (am.which_month, 'Mon YYYY')  AS month
       , ph.phase_number
       , NVL(sum ( (CASE
                   WHEN ph.date_finished IS NULL OR ph.date_finished > last_day(am.which_month)
                   THEN last_day(am.which_month)
                   ELSE ph.date_finished
                END
               ) - ph.date_started + 1
             ) / count(def.def_id), 0) as avg_days
    FROM all_months am
         LEFT OUTER JOIN  a_phase_membership  ph  PARTITION BY (ph.phase_number)
            ON  am.which_month <= ph.date_started
            AND am.next_month  >  ph.date_started
            AND ph.date_started <= last_day(am.which_month)  -- May not be needed
            AND ph.active = 1
         LEFT OUTER JOIN  a_engagement  ce
            ON  ph.mpm_eng_id = ce.engagement_id
            AND ce.court_name IS NOT NULL  -- or something involving LIKE
         LEFT OUTER join  a_defendant     def
            ON  ce.defendant_id = def.def_id
            AND def.active = 1
   GROUP BY ROLLUP(phase_number, am.which_month)
   ORDER BY  am.which_month
          ,  ph.phase_number
  ;
  
  The output is:

• Rewrite the query with joins, and group by

  Hello
  
  It's an interview question.
  
  Table names: bookshelf_checkout
  virtual library
  
  And the join condition between these two tables is title
  
  We need to rewrite under request without using the join condition and group by clause?
  
  

  SELECT b.title,max(bc.returned_date - bc.checkout_date) "Most Days Out"
             FROM bookshelf_checkout bc,bookshelf b
             WHERE bc.title(+)=b.title
             GROUP BY b.title;

  When I was in College, I read most of SELECT statements can be replaced by operations base SQL (DEFINE the OPERATORS). Now, I am rewriting the query with SET operators, but not able to get the exact result.
  
  Kindly help me on this.
  
  Thank you

• The join SQL query help

  I'm just having a bit of troubel get a correct join query - I thought it was an Inner Join, but I don't get the results I expect.

  My table structure is:

  Table: lodges

  LodgeID (PK)

  Lodge

  etc.

  Table: implemented application

  NominationID (PK)

  Category

  LodgeID

  Year

  So I try to use this structure to replicate this page:

  http://www.safariawards.com/nominees12/

  That is to say a list of boxes for each category, they are appointed on.

  The query I've tried looks like this:

  SELECT appointments. LodgeID, lodges. Lodge, applications. NominationID, applications. Lodges INNER JOIN applications category IT lodges. LodgeID = nominated. NominationID WHERE category = "Best property of Safari in southern Africa" ORDER BY Lodge

  But this product:

  http://www.safariawards.com/nominees12/southernafrica.php

  Its the right number of results, but not the list on the right of the boxes - for example British Airwways is not LodgeID 786

  If anyone could help with the SQL right for what would be well appreciated.

  That you join on the wrong column. Try this:

  SELECT appointments. LodgeID, lodges. Lodge, applications. NominationID, applications. Lodges INNER JOIN applications category IT lodges. LodgeID = nominated. LodgeID WHERE category = "Best property of Safari in southern Africa" ORDER BY Lodge

• Need help in the optimization of the query with the Group and joins by clause

  I'm having the problem by running the following query... It takes a lot of time. To simplify, I added the two tables FILE_STATUS = stores the file load details and COMM table Board table job showing records treated successfully and which was communicated to the other system real. Records with status = T is trasnmitted to another system and traansactions with P is waiting.

  CREATE TABLE FILE_STATUS
  (FILE_ID VARCHAR2(14),
  FILE_NAME VARCHAR2(20),
  CARR_CD VARCHAR2(5),
  TOT_REC NUMBER,
  TOT_SUCC NUMBER);
  
  CREATE TABLE COMM
  (SRC_FILE_ID VARCHAR2(14),
  REC_ID NUMBER,
  STATUS CHAR(1));
  
  INSERT INTO FILE_STATUS VALUES ('12345678', 'CM_LIBM.TXT', 'LIBM', 5, 4);
  INSERT INTO FILE_STATUS VALUES ('12345679', 'CM_HIPNT.TXT', 'HIPNT', 4, 0);
  
  INSERT INTO COMM VALUES ('12345678', 1, 'T');
  INSERT INTO COMM VALUES ('12345678', 3, 'T');
  INSERT INTO COMM VALUES ('12345678', 4, 'P');
  INSERT INTO COMM VALUES ('12345678', 5, 'P');
  COMMIT;

  Here's the query I wrote to give me the details of the file that has been loaded into the system. He reads the table of State and the commission files to display the name of the file, total records loaded, total at the table of the commission and the number of records which has finally been passed successfully loaded (Status = T) with other systems.
  

  SELECT 
      FS.CARR_CD 
      ,FS.FILE_NAME 
      ,FS.FILE_ID
      ,FS.TOT_REC
      ,FS.TOT_SUCC
      ,NVL(C.TOT_TRANS, 0) TOT_TRANS
  FROM FILE_STATUS FS
  LEFT JOIN
  (
      SELECT SRC_FILE_ID, COUNT(*) TOT_TRANS
      FROM COMM
      WHERE STATUS = 'T'
      GROUP BY SRC_FILE_ID
  ) C ON C.SRC_FILE_ID = FS.FILE_ID
  WHERE FILE_ID = '12345678';

  In production, this request has several joins and takes a long time to deal with... the main culprit for me is the join on the COMM table to count the number of number of transactions sent. Please can you give me tips to optimize this query to get results faster? What I need to delete the Group and use the partition or something else. Help, please!

  Don't know if it will be faster based on the information provided, but analytical functions offer an alternative approach;

  select carr_cd, file_name, file_id, tot_rec, tot_succ, tot_trans
    from (select fs.carr_cd,
                 fs.file_name,
                 fs.file_id,
                 fs.tot_rec,
                 fs.tot_succ,
                 count(case
                          when c.status = 'T' then
                           1
                          else
                           null
                        end) over(partition by c.src_file_id) tot_trans,
                 row_number() over(partition by c.src_file_id order by null) rn
            from file_status fs
            left join comm c
              on c.src_file_id = fs.file_id
           where file_id = '12345678')
   where rn = 1;
  
  CARR_CD FILE_NAME            FILE_ID           TOT_REC   TOT_SUCC  TOT_TRANS

• How to indicate the query term not found using PHP server behaviors

  I try to use Dreamweaver server behaviors to a search for MySQL in a PHP environment and want to be able to tell the user that their search warrant was not found. I have a form that they fill and can use the server foundcount behavior to determine if the query data, they enter matches all records in the database (which works fine, as does to recover the data, if there is a match). But in my form, I want the fields of feedback to be uninhabited until they enter an order number and I do research. If there is a match, I have to return the data, but if there is no match, I want to send a message back saying that.
  Problem is that code PHP that includes the form being the action, if I try to set a flag to enable or disable a default condition (no error messages) to be to so display a message 'number command not found', the flag will reset when the form action is executed. I have to believe that this type of error reporting is common, so expect Dreamweaver to have this ability. Am I missing something? Thank you.

  You say that you have a record set if there are records. Just do a
  Recordset conditional that registers, the user sees records, remains a
  message no records have been found.

• How to specify an outer join in the query designer

  I quickly built a large query with the query designer, and it works very well, but does not produce 9 disks on 2200 - so I need to change to an outer join.
  
  My problem is that I can't find a way to specify an outer join. I tried to change the query, query builder formed, but it won't let me.
  
  I know that I can capture the query, edit and run it in sql developer and that works fine, but I want to use the Query Builder as it is the fastest way I know to quickly add and remove items - my users don't know exactly what that it to include.
  
  I know it's kind of a trivial question, but I searched the forum, manual, the web and no luck
  
  Thanks for any help you can give

  Hi Glenn,.

  When you use the query designer to create the sql statement, you must click on the empty box to the right of the fields in each table to create the join. When you are finished, you should see a line drawn between the two tables. Click on this line, and a small window appears allowing you to select inner outer or right outer joins, left.

  When the report was created, however, you must change the statement. For example, if you use the query designer to join DEPT at EMP based on the DEPTNO field on the two tables, you get:

  select      "DEPT"."DEPTNO" as "DEPTNO",
        "DEPT"."DNAME" as "DNAME",
        "DEPT"."LOC" as "LOC",
        "EMP"."EMPNO" as "EMPNO",
        "EMP"."ENAME" as "ENAME",
        "EMP"."JOB" as "JOB",
        "EMP"."MGR" as "MGR",
        "EMP"."HIREDATE" as "HIREDATE"
   from      "EMP" "EMP",
        "DEPT" "DEPT"
   where   "DEPT"."DEPTNO"="EMP"."DEPTNO"
  

  This is to change:

  select      "DEPT"."DEPTNO" as "DEPTNO",
        "DEPT"."DNAME" as "DNAME",
        "DEPT"."LOC" as "LOC",
        "EMP"."EMPNO" as "EMPNO",
        "EMP"."ENAME" as "ENAME",
        "EMP"."JOB" as "JOB",
        "EMP"."MGR" as "MGR",
        "EMP"."HIREDATE" as "HIREDATE"
   from      "EMP" "EMP"
        LEFT OUTER JOIN "DEPT" "DEPT" ON "DEPT"."DEPTNO"="EMP"."DEPTNO"

• Need help to understand the query result

  Hi gurus

  I was reading one of the question here in this forum and its link is below:

  Query required for scenario

  I had some confusion related to this code and don't understand the logic of the out put, see query below:

  Query

  with sub_services as

  (

  Select su_seq 12323, 'HLR1' so_id, 1 seq Union double all the

  Select su_seq 12323, "HLR2' so_id, seq 2 Union double all the

  Select su_seq 12323, "A09" so_id, seq 3 of all the double union

  Select su_seq 12333, "MO1" so_id, seq 4 Union double all the

  Select su_seq 12333, "MO2' so_id, seq 5 Union double all the

  Select su_seq 12333, "A09" so_id, 6 seq in union double all the

  Select su_seq 12333, 'M0CR' so_id, seq 7 Union double all the

  Select su_seq 12999, "LOL1' so_id, seq 8 Union double all the

  Select su_seq 12999, "LOL2' so_id, seq 9 double

  )

  Select *.

  of sub_services b

  where exists (select 1 from sub_services

  where su_seq = b.su_seq

  and so_id = 'A09.

  )

  order by 2;

  The query result

  12323 A09 3

  12333 6 A09

  12323 HLR1 1

  12323 HLR2 2

  12333 M0CR 7

  12333 4 MO1

  12333 5 MO2

  According to my understanding, the above query should return records in red only because of her is below command

  It exists (select 1 from sub_services

  where su_seq = b.su_seq

  and so_id = 'A09.

  but don't know why he's back 7 files, can someone help me understand the result...

  It is query is functionally identical to the PL/SQL block, but much more effective.

  declare

  number of l_res;

  Start

  for line (select *)

  sub_services) loop

  Start

  Select 1 from l_res

  of sub_services

  where su_seq = row.su_seq and

  so_id = "A09" and

  rownum = 1;

  exception when

  NO_DATA_FOUND then

  null;

  end;

  end loop;

  end;

  Essentially every row in the outer query are tested against him exists query.  Given the correlation between two requests is based only on su_seq each line with a su_seq value returned by him is returned in the output.

  Another way to think he uses instead a join condition.  This query is equivalent to the query to exist

  Select the main

  of main sub_services

  Join select (separate su_seq

  of sub_services

  where so_id = "A09") cond

  We main.su_seq = cond.su_seq;
