• Change of shape joining multi tables SQL...

  I need to be able to join the tables in the detail section of my master-detail form. Since I have more than three paintings to join, I think that APEX needs to use "ROWID" to track the value of the key of the primary table. When I try substitute basic sql generated for the report to my own joined table I get an error return "IMPOSSIBLE of ANALYSER. If I remove "ROWID" in the statement, then fine. Here's the statement from the apex generated:
  
  Select
  "ROWID",.
  "PO_ID."
  "PO_DET_ID,"
  "CHANGE_ORDER,"
  'START_DATE ',.
  'END_DATE ',.
  "PO_DET_AMT,"
  "SCOPE."
  "PO_STATUS,"
  "MRS."
  of ' #OWNER # '. " PO_DETAILS ".
  where "PO_ID" =: P240_PO_ID
  
  However, I need for the statement as follows:
  
  Select "ROWID",.
  po_details.po_id,
  po_details.po_det_id,
  po_details.change_order,
  po_details.start_date,
  po_details.end_date,
  po_details.po_det_amt,
  po_details. Scope,
  po_details.po_status,
  po_details. WBS
  of PO_DETAILS, IN., WBS, PROJECT
  where po_details.po_id = po.po_id
  and po.po_number = wbs.po_number_id
  and po_details.wbs = wbs.wbs_number_id
  and substr (wbs.wbs_number_id, 1, 6) = project.wbs_sequence
  and project.project_number = nvl(:F101_FPC_NUMBER,project.project_number)
  and po_details.po_id =: P240_PO_ID
  
  Then, I get the following ORACLE error:
  
  •Query cannot be parsed in the generator. If you believe that your query is syntactically correct, check the generic "columns" box below the source of the region without analysis. ORA-00918: column ambiguously defined
  
  I'm guessing that the column "defined ambiguous ' is ROWID.
  
  SELECT the query aspect works fine if I remove ROWID, but I then cannot update the table when the user needs to change the data. I get an exception defined by the user.
  
  I am new to APEX, so I do not know there are certain aspects that I'm missing.
  Any tips?

  There is no way to use a join of multiple tables in the APEX?

  Of course you can. Have you tried again (with the help of PO_DETAILS ROWID in the select statement)?

  I tried with a form on EMP and then modified the query to:

  select
  e."ROWID",
  e."EMPNO",
  e."ENAME",
  e."JOB"
  from "#OWNER#"."EMP" e, dept d
  where e.deptno = d.deptno
  and d.deptno = :P14_DEPTNO
  

  IMHO, it's simply more transparent if you use a view as the source. You select a view, and you update the same point of view.

• Retrieve all records in the selected master child multi tables

  Hello
  I use JDeveloper 11.1.1.4 version and using ADF - BC in my project.
  I have a one-to-one simple child master [several] in my project.
  In my view page, I display this master child [Ex: EmpVo1-> DeptVo2] in the form of tables.
  
  I have multi-selection enabled for the main table.
  My requirement is that, on the multi by selecting the lines in the main tables, I want to get all the child records in my grain of support.
  If a master has 3 child records line and another main line has 4 child records and on the selection of several of these two records in the primary table, I should get all the child records in my grain of support.
  I need it to implement the cascade delete feature.
  Here is the sample code coin
  --------------------------------------------
  
  (1) called on selecting rows in the master table
  
  {} public void onRSCGrpSelect (SelectionEvent selectionEvent)
  Add the code in the event here...
  ADFUtil.invokeEL ("#{bindings.") RscGroupVO1.collectionModel.makeCurrent} «»
  new class [] {SelectionEvent.class},
  (New Object() {selectionEvent});
  
  RowKeySet rowKeySet = (RowKeySet) tblRSCGrp.getSelectedRowKeys ();
  CollectionModel cm = (CollectionModel) tblRSCGrp.getValue ();
  
  for (object facesTreeRowKey: rowKeySet) {}
  cm.setRowKey (facesTreeRowKey);
  RowData = JUCtrlHierNodeBinding
  (JUCtrlHierNodeBinding) cm.getRowData ();
  Line = rowData.getRow ();
  System.out.println ("\n" +)
  row.getAttribute (0) + ":" + row.getAttribute (1) +.
  (":" + row.getAttribute (2));
  
  System.out.println ("display the child records");
  displayChildRecords (row.getAttribute (0));
  
  }
  
  }
  
  2 private void displayChildRecords (Object rscGrp) {}
  ViewObject rscMapVo = getRscMapViewObj();
  RowSetIterator rsI = rscMapVo.createRowSetIterator (null);
  While (rsI.hasNext ()) {}
  Line = rsI.next ();
  System.out.println ("\n" +)
  row.getAttribute (0) + ":" + row.getAttribute (1) +.
  (":" + row.getAttribute (2));
  }
  rsI.closeRowSetIterator ();
  }
  
  But the problem is that he is always giving me the last selected lines child details.
  
  Please suggest the error that I do.
  
  Thank you
  Praveen

  Your problem is to use makecurrent, which should not be used on a multi selection table. Then, if you have a relationship master detail you should have a view link between them. In this case, you can expose a method as you master to get the related child line. Not need to get the VO itself you can use the accessors of child iterator to obtain registration of the child.

  public void onRSCGrpSelect(SelectionEvent selectionEvent) {
  // Add event code here...
  RowKeySet rowKeySet = (RowKeySet)tblRSCGrp.getSelectedRowKeys();
  CollectionModel cm = (CollectionModel)tblRSCGrp.getValue();
  
  for (Object facesTreeRowKey : rowKeySet) {
  cm.setRowKey(facesTreeRowKey);
  JUCtrlHierNodeBinding rowData =
  (JUCtrlHierNodeBinding)cm.getRowData();
  Row row = rowData.getRow();
  //cast to the right row class
  EmpEmpVoRow empRow = (EmpEmpVoRow) row;
  // now you cann access the child row iterator
  RowSetIterator it = empRow.getDepVO();
  //now you cna iterate over the child rows
  System.out.println("\n" +
  row.getAttribute(0) + " :: " + row.getAttribute(1) +
  " :: " + row.getAttribute(2));
  
  System.out.println("Displaying Child Records");
  //use hte child rows here
  
  }
  
  }
  

  Don't know if the code compiles out of the box (do this on the train :-)

• JOIN the question... Join two tables without omitting lines

  I came across a problem that should be an easy fix (I hope), but I'm having a hard time to come up with a solution.

  Basically I have two tables, one with the actual amounts with the budget. I have to write a sql statement select that joins these tables together and includes all of their lines. I was able to join the tables by using JOIN, LEFT JOIN and RIGHT JOIN, but it always fails the lines I need.

  Below, I have examples of my tables (AMOUNT_TABLE and BUDGET_TABLE). For simplicity, I built the examples to show the same values in the first four columns, with the 5th and 6th columns (SUB_ACCOUNT, AMOUNT, BUDGET) as the only values that are different. My actual tables are not quite that simple, but I don't think it was relavent to this issue.

  AMOUNT_TABLE

  FISCAL_YEAR	PERIOD	ACCT_UNIT	ACCOUNT	SUB_ACCOUNT	AMOUNT
  2013

  111111555555000010020131111115555551000100201311111155555520001002013111111555555300010020131111115555554000100

  BUDGET_TABLE

  FISCAL_YEAR	PERIOD	ACCT_UNIT	ACCOUNT	SUB_ACCOUNT	BUDGET
  2013

  1111115555553000200201311111155555540002002013111111555555500020020131111115555556000200

  Here's what I hope. Note that SUB_ACCOUNTs 0000, 1000, and 2000 show without budget amounts since there is not a corresponding line in the BUDGET_TABLE. And same for SUB_ACCOUNTs 5000 and 6000, they show budgets with no amount because there is not a corresponding line in the AMOUNT_TABLE.

  (exit)

  FISCAL_YEAR	PERIOD	ACCT_UNIT	ACCOUNT	SUB_ACCOUNT	AMOUNT	BUDGET
  2013	1	11111	555555	0000	100	0
  2013	1	11111	555555	1000	100	0

  2013	1	11111	555555	6000	0	200

  If all goes well, my question is clear. Any help on this would be greatly appreciated. Thanks in advance.

• Outer join complete Multi Table

  What is the syntax to make a full outer join on three tables. All the examples I can find use using the clause, but in my case, the column names are not the same in the three tables

  Hello

  Use IT instead of USE.

  Assuming that all the 3 tables will have a common value in a column (whatever it is called):

  ...
  FROM           table_x  x
  FULL OUTER JOIN      table_y  y     ON     y.idy     = x.idx
  FULL OUTER JOIN      table_z  z     ON     z.idz     = COALESCE (x.idx, y.idy)
  

  When comes the time to join table_z, you won't know which of the previous tables match, so you must use COALESCE to try them all.

  If you need to join several tables in this way, the expression of COALESCE for the nth table will have (n - 1) arguments.

• difference between Inner Join join natural r

  Experts,

  I'm trying to understand the difference between Natural Join and inner join.

  Inner join: the following query provides 106 lines based on two tables

  SQL > SELECT EMPLOYEE_ID EID, last NAME, DEPT_NAME DEPARTMENT_NAME

  2 EMPLOYEES A, B MINISTRIES

  3. WHERE A.DEPARTMENT_ID = B.DEPARTMENT_ID

  4 order employee_id;

  Natural Join: This is the combination or combined result of all the columns in both tables.

  When I run the Sub statement, it combines employees and the table from department of a HR schema and provides only 32 ranks

  SQL > select employe_id, first_name, department_name

  2 departments of NATURAL JOIN employees;

  
  

  EMPLOYEE_ID NAME DEPARTMENT_NAME

  question: why the NATURAL JOIN query omit the employee_id 103 and on what basis it omit a few other employee_id

  Thanks in advance

  Hello

  The main difference is that INNER JOIN is used in real life; NATURAL JOIN is used only in textbooks.

  More rigorously, FRANCKLIN JOIN is an inner join, involving all the columns that have the same name.  The hr.departments and hr.employees have 2 columns with the same name: department_id and manager_id, so

  OF hr.departments d

  NATURAL JOIN e hr.employees

  is equivalent to

  OF hr.departments d

  INNER JOIN hr.employees e ON e.department_id = d.deparment_id

  AND e.manager_id = d.manager_id

  or, using the old join syntax

  OF hr.departments d

  e hr.employees

  WHERE e.department_id = d.deparment_id

  AND e.manager_id = d.manager_id

  Normally this site does not display the <>inequality operator; He thinks it's some kind of beacon.
  Whenever you post on this site, use the other inequality operator (equivalent), *! = *.

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and INSERT, only relevant columns instructions) for all the tables involved and the results desired from these data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.
  You will get better results faster if you always include this information whenever you have a problem.

• Join of tables?

  Hello
  
  
  My 1st question
  

  Sometimes i have hard time in deciding the weather to use equi join or left join or right join ?? 
  
  After looking at the data model i can understand how the tables can be joined on what attribute but i lack in making decision weather to use left join or right join for one to many or many to one relationships 
  
  I know the concept of right join and left join but i get confused in what scenario i need to use left join or right join and what join to use for one to many relationships or many to one relationships
  
  If you have any techniques or suggetions how to use them that will be great!!

  My 2nd question
  
  
  
  
  ___Table1___ TableA
  | | | |
  Table2, table3 table 4 < - TableC - TableB-|
  
  Table 1 a 1 of many relationships of table2, table 3, table 4
  
  I, e Table1-> table 2, table 3, table 4
  
  Table A has many relationships in table 1 B, i, e TableA-> table B
  
  Table B has 1 in-several in Table C, i, e table B-> table C
  
  Table C has many relationships in table 4, i, e 1 C table-> table 4
  
  
  I know the attributes to use to join these tables, but my question is what join what I use left join or right join or Equi join (I don't think I can use this)
  
  
  Something like that in my SQL query in where clause (I don't know if this is right).
  
  Where
  Table1. ID = table2. ID
  or table1.my_field = table3.id
  or table1.my_field = table4.id
  or tableA. ID = tableB.id---(ce que je dois opérateur OR ou opérateur AND???)
  or tableB.id = TableC.id
  or tablec.id = table4.id
  
  I don't know if this right or do I have to use the left join on right join or and or operator operator 'OR' is something I m really confued subject.
  
  
  
  
  Any advice greatly appriciated thank you!

• Case Based Condition of inner join in SQL query

  Hi Experts,
  

  CREATE TABLE PRODUCT_PRICE(PRODUCT_ID INTEGER,PRICE FLOAT);
  INSERT INTO PRODUCT_PRICE VALUES(1,1);
  INSERT INTO PRODUCT_PRICE VALUES(2,2);
  INSERT INTO PRODUCT_PRICE VALUES(3,1);
  INSERT INTO PRODUCT_PRICE VALUES(4,1);
  INSERT INTO PRODUCT_PRICE VALUES(5,3);
  INSERT INTO PRODUCT_PRICE VALUES(0,4);

  CREATE TABLE PRODUCT_TABLE (PRODUCTID INTEGER,OTHERID INTEGER);
  INSERT INTO PRODUCT_TABLE VALUES (1,0);
  INSERT INTO PRODUCT_TABLE VALUES (2,0);
  INSERT INTO PRODUCT_TABLE VALUES (3,1);
  INSERT INTO PRODUCT_TABLE VALUES (4,1);
  INSERT INTO PRODUCT_TABLE VALUES (5,2);

  I need to match the product_id = 0 to get the price of the product when there is othersid in the product table (otherid > 0). For this I created the query below.
  

  SELECT 
      PRODUCT_ID,
      PRICE 
  FROM 
      PRODUCT_TABLE
      INNER JOIN PRODUCT_PRICE ON PRODUCT_ID=PRODUCTID
  WHERE
      OTHERID=0
  UNION ALL
  SELECT 
      PRODUCT_ID,
      PRICE 
  FROM 
      PRODUCT_TABLE
      INNER JOIN PRODUCT_PRICE ON PRODUCT_ID=0
  WHERE
      OTHERID>0;

  My Question is, is that any way the SQLQuery above can be simplified in CASES and INTERNAL CONDITION JOIN in a single SQL QUERY?
  
  I can work around something like that,
  

  SELECT 
      PRODUCT_ID,
      PRICE 
  FROM 
      PRODUCT_TABLE
      INNER JOIN PRODUCT_PRICE ON * CASE WHEN OTHERID>0 THEN PRODUCT_ID=0 ELSE PRODUCT_ID=PRODUCTID END*

  Thank you

  SELECT CASE WHEN PT.OTHERID = 0 THEN PT.PRODUCTID ELSE 0 END AS PRODUCT_ID, PP.PRICE
    FROM PRODUCT_TABLE PT,  PRODUCT_PRICE PP
      WHERE CASE WHEN PT.OTHERID =0 THEN PT.PRODUCTID ELSE 0 END = PP.PRODUCT_ID
  

  Should it?

• 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),
    primary key(id)
  );
  
  create table class(
   id number not null,
   name varchar2(80),
   day number,
   course_id number not null,
   primary key(id),
   foreign key(course_id) references course(id)
  );
  
  create table student_course(
    id number not null,
    student_id number not null,
    course_id number not null,
    class_id number,
    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?

  Thanks in advance for any help.

  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.

• Join the tables in the responses

  I would like to know if it is possible to join the tables together as below in the answers?
  
  Select a.Field1, b.Field1
  FROM tableA an outer join left tableA b on
  a.Field1 = b.Field

  If you want to make an INNER JOIN, and then type INNER JOIN instead of LEFT INNER JOIN.

  If you want to left outer join and LEFT OUTER JOIN instead of INTERNAL LEFT JOIN type.

  Nothing asked as a left inner join. That is why it gives error + [nQSError: 27002] near +.

  Thank you

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

  Hi all
  
  I'm Ann.
  
  I have a select statement that is used to calculate statistics for a month (October 2012 in this example)
  Select ph.phase_number
  sum ((case
  WHEN ph.date_finished IS NULL or ph.date_finished > last_day (TO_DATE (' ' Oct 2012 ', ' MY YYYY' "))
  THEN last_day (TO_DATE (' ' Oct 2012 ', ' MY YYYY' "))
  Of OTHER ph.date_finished
  END)
  (-ph.date_started + 1) / count (def.def_id) as avg_days
  Ph phase_membership
  inner join court_engagement this on ph.mpm_eng_id = ce.engagement_id
  join in-house defendant def on ce.defendant_id = def.def_id
  where def.active = 1
  and ph.date_started < = last_day (TO_DATE (' ' Oct 2012 ', ' MY YYYY' "))
  and ph.active = 1
  and UPPER (ce.court_name) LIKE '% '.
  Rollup Group (phase_number)
  ;
  
  The result is as below
  Phase_Number AVG_DAYS
  Phase One 8.6666666666666667
  Phase two 14.6
  Phase three 12
  11.4615365
  
  I have another list of selection mainly the list of months between two date value.
  Select to_char (which_month, 'LUN YYYY') as display_month
  de)
  Select add_months (to_date (' ' August 2012 ', ' MY YYYY' "), rownum-1) which_month
  of object
  where
  rownum < = months_between (to_date (' ' Oct 2012 ', ' MY YYYY' "), add_months (to_date (' ' August 2012", "MY YYYY"), - 1))
  order of which_month)
  
  The query result is as below
  
  DISPLAY_MONTH
  
  AUGUST 2012
  SEP 2012
  OCT 2012
  
  Is it possible I can join these two select statement above to generate a comparable result:
  
  Days of month Phase number Avg
  August 2012 Phase One 8.666
  Sep 2012 Phase One 7.66
  Oct 2012 Phase One 5,66
  August 2012 Phase two 8.666
  Sep 2012 Phase two 7.66
  Oct 2012 Phase two 5,66
  August 2012 Phase three 8.666
  Sep 2012 Phase three 7.66
  Oct 2012 Phase three 5,66
  
  Or
  Days of month Phase number Avg
  August 2012 Phase One 8.666
  August 2012 Phase two 7.66
  August 2012 Phase three 5,66
  Sep 2012 Phase One 8.666
  Sep 2012 Phase two 7.66
  Sep 2012 Phase three 5,66
  Oct 2012 Phase One 8.666
  Oct 2012 Phase two 7.66
  Oct 2012 Phase three 5,66
  
  And it can be controlled by Phase number or month.
  My other colleague suggested I should use a left outer join, but after having tried many ways, I'm still stuck.
  
  I tried select is
  Select a.display_month, b.* in)
  Select to_char (which_month, 'LUN YYYY') as display_month

  (Select to_char (ph.date_finished, 'MY YYYY') as join_month, ph.phase_number)
  sum ((case
  WHEN ph.date_finished IS NULL or ph.date_finished > last_day (TO_DATE (a.display_month, 'MY YYYY'))
  THEN last_day (TO_DATE (a.display_month, 'MY YYYY'))

  and UPPER (ce.court_name) LIKE '% '.
  To_char (ph.date_finished, 'MY YYYY'), group (phase_number) rollup) b
  On a.display_month = b.join_month
  
  but then I get an error
  SQL error: ORA-00904: "A." "" DISPLAY_MONTH ": invalid identifier
  
  I need to view a report on the APEX with option for people to download at least format CSV.
  Already 1 inteactive report in the page, so I don't think adds another interactive report without using the iframe trick.
  
  If any of you have any ideas, please help.

  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:
  MONTH    PHASE_NUMBER           AVG_DAYS
  -------- -------------------- ----------
  Aug 2012 PHASE ONE                     0
  Aug 2012 PHASE THREE                   0
  Aug 2012 PHASE TWO                     0
  Sep 2012 PHASE ONE                    12
  Sep 2012 PHASE THREE                   1
  Sep 2012 PHASE TWO                     9
  Oct 2012 PHASE ONE                     8
  Oct 2012 PHASE THREE                   0
  Oct 2012 PHASE TWO                    14
           PHASE ONE                    11
           PHASE THREE                   1
           PHASE TWO                  11.5
                                9.71428571
  

  I don't know if that's really what you want. In the case check it and let me know.

  Kind regards.

  The title you chose for this thread is "inner join is not eliminating duplicates!
  Inner joins (or other types of joints) are not supposed to remove duplicates. Use SELECT DISTINCT to remove duplicates, which is exactly the same lines.
  You don't have to duplicate. For example, these lines of your result set:

  `        CNAME     CNAME
  1     Perira     Hoffman
  10     Hoffman     Perira
  

  are not identical; Indeed, the two columns are different.

  Ideally, it should up to 5 rows, but it does not return these lines for an e.g. Hoffman perish since I'm Perira Hoffman already.

  Please report the exact output of the sample data you want. (As said by Hoek, post CREATE TABLE and INSERT statements for the sample data too.)

  values (3,5,4,0);
  insert into hotel_service (hotel_id, qty_room, qty_people,qty_people_extra)
  values (4,6,2,1);
  insert into hotel_service (hotel_id, qty_room, qty_people,qty_people_extra)
  values (4,12,3,1);

  As you can see I have Hotels with basic information, persons of type hotel_people (1:baby, 2:young and 3:Adult), which contains the type of people that each hotel can accommodate with min max age and hotel_service that contains the info from the number of rooms and the amount of people that can be in each room.
  I'm trying to get the records that match my condition as:
  1. I want to get the hotels that can accommodate 4 pieces with adults of 3 for each room.
  2 get hotels that can accommodate 6 rooms 2 where 2 of the bedrooms can have 1 young (3 people per room) and young people 9 years.
  
  For 1:

  select h.hotel_id, h.hotel_name, ss.qty_room, t.type_des, ss.qty_people, p.age_min, p.age_max
  from hotel h
  inner join hotel_service ss on h.hotel_id = ss.hotel_id
  inner join hotel_people p on h.hotel_id = p.hotel_id
  inner join people_type t on p.people_type_id = t.people_type_id
  where ss.qty_room >= 4
  and t.people_type_id = 3
  and ss.qty_people >= 3

  For 2:

  select h.hotel_id, h.hotel_name, ss.qty_room, t.type_des, ss.qty_people, p.age_min, p.age_max
  from hotel h
  inner join hotel_service ss on h.hotel_id = ss.hotel_id
  inner join hotel_people p on h.hotel_id = p.hotel_id
  inner join people_type t on p.people_type_id = t.people_type_id
  where ss.qty_room >= 6
  and ss.qty_people >= 3
  and t.people_type_id in (2,3)
  and 9 between p.age_min and p.age_max

  This does not work, the start of the query becomes more complex if I try to search for multiple rooms with a different number of people and children of different ages.
  Can anyone help with this?
  Thank you

  ... Yes, what I need is a hotel that can accommodate TWO adults and youth. What do you mean by two copies?

  Right now I read something on the Grand Duke by Gilbert. I also have a book with the complete works of Gilbert, so I can leave it open, and when I see a reference in the commentary, I see exactly what the author is talking about in the book. However, when the comment compares some parts of this game to the other plays of Gilbert, The Yeomen of the Guard , it gets hard, because I have to keep changing the pages in the complete works, and I can't see both at the same time. It would be much easier if I could get a full second copy of the work; then I could leave a copy of the Grand Duke and leave the other copy open to The Yeomen of the Guard . This is similar to what you should do with the table of hotel_people, and what I do with the table scott.emp below.

  Imagine (using tables in the scott schema) you have to find the departments where both an analyst and a clerk to work.
  This:

  SELECT DISTINCT
            d.*
  FROM       scott.dept     d
  JOIN       scott.emp     e  ON     d.deptno     = e.deptno
  WHERE       job          IN ('ANALYST', 'CLERK')
  ORDER BY  d.deptno
  ;
  

  product

  DEPTNO DNAME          LOC
  ------ -------------- -------------
      10 ACCOUNTING     NEW YORK
      20 RESEARCH       DALLAS
      30 SALES          CHICAGO
  

  because all these departments have either an analyst or a clerk. However, only deptno = 20 a time .
  If, instead of a single table of big job, you have a separate table for each Olympic Games, then you might do something like this:

  SELECT DISTINCT
            d.*
  FROM       scott.dept     d
  JOIN       analyst     a  ON     d.deptno     = a.deptno
  JOIN       clerk          c  ON     d.deptno     = c.deptno
  ORDER BY  d.deptno
  ;
  

  Of course, you don't have tables separated like that, but you could generate result sets who behaved as separte tables, for example:

  WITH     analyst          AS
  (
       SELECT  *
       FROM     scott.emp
       WHERE     job     = 'ANALYST'
  )
  ,     clerk          AS
  (
       SELECT  *
       FROM     scott.emp
       WHERE     job     = 'CLERK'
  )
  SELECT DISTINCT
            d.*
  FROM       scott.dept     d
  JOIN       analyst     a  ON     d.deptno     = a.deptno
  JOIN       clerk          c  ON     d.deptno     = c.deptno
  ORDER BY  d.deptno
  ;
  

  Note that the main request is exactly what I posted earlier.
  What produces the right output:

  DEPTNO DNAME          LOC
  ------ -------------- -------------
      20 RESEARCH       DALLAS
  

  There is no need to actually generate separate result sets, however. You can use two copies of the table scott.emp in the same query, as follows:

  SELECT DISTINCT
            d.*
  FROM       scott.dept     d
  JOIN       scott.emp     a  ON     d.deptno     = a.deptno
  JOIN       scott.emp     c  ON     d.deptno     = c.deptno
  WHERE       a.job          = 'ANALYST'
  AND       c.job          = 'CLERK'
  ORDER BY  d.deptno
  ;
