Inline query vs cross join

• Difference between a CROSS JOIN and a Cartesian product of the noted comma?

  Hello everyone,
  
  Oracle version: Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64 bit
  OS: Linux Fedora Core 17 (x86_64)
  
  I was practicing on recursive subquery factoring based on oracle examples available in the documentation
  http://docs.Oracle.com/CD/E11882_01/server.112/e26088/statements_10002.htm#i2129904
  
  I was working on an example that displays the hierarchy of each manager with related employees. Here's how

  WITH tmptab(empId, mgrId, lvl) AS
  (
      SELECT  employee_id, manager_id, 0 lvl
      FROM employees
      WHERE manager_id IS NULL
      UNION ALL
      SELECT  employee_id, manager_id, lvl+1
      FROM employees, tmptab
      WHERE (manager_id = empId)
  )
  SEARCH DEPTH FIRST BY mgrId SET order1
  SELECT LPAD(' ', lvl * 3, ' ') || empId AS empId
  FROM tmptab;

  Which gives the desired result

  SQL> 

  However, by chance, I noticed that if I put CROSS JOIN instead of put a comma between table names, the same query behaves differently.
  
  In other words, if instead of writing

  . . .
  UNION ALL
      SELECT  employee_id, manager_id, lvl+1
      FROM employees, tmptab
      WHERE (manager_id = empId)

  I am writing

  . . .
  UNION ALL
      SELECT  employee_id, manager_id, lvl+1
      FROM employees CROSS JOIN tmptab
      WHERE (manager_id = empId)

  I get the following error message

  ERROR at line 4:
  ORA-32044: cycle detected while executing recursive WITH query

  Any idea?
  Correct me if I'm wrong, but I remember, oracle supports as many JOIN CROSSROADS notation for Cartesian product (vector product =). For example

  SQL> WITH tmptab1 AS

  So if the two rated commas and CROSS JOIN have the same semantics, why do I get a cycle mentioned above cites recursive subquery factoring while the same query works pretty well with comma between table instead of CROSS JOIN names? Because if a cycle is detected (= current element ancestor) it means that the product with the CROSS JOIN notation produces duplicates which are absent in the result of the Cartesian product rated comma.
  
  I would appreciate it if you could kindly shed some light.
  
  Thanks in advance,

  There is no doubt that a Cartesian product (also called cross join) is a join. If loops in a WITH recursive clause are detected after completing the joins, but before other conditions apply, the relevant question here is "what are the requirements to join?
  In the ANSI syntax, the distinction is always clear. Join conditions occur in the... Clause WE

  SELECT  employee_id, manager_id, lvl + 1
  FROM      employees
  JOIN        tmptab          ON  (manager_id = empId)     -- Join condition
  ;
  

  and other conditions occur in the WHERE (or HAVING or CONNECT BY) clause.

  SELECT  employee_id, manager_id, lvl + 1
  FROM            employees
  CROSS JOIN         tmptab
  WHERE  (manager_id = empId)     -- NOT a join condition
  ;
  

  In the joins of the former, it seems to be the case that any condition involving 2 or more tables (or the + indicator of outer join) is a condtion of join:

  SELECT  employee_id, manager_id, lvl + 1
  FROM      employees
  ,         tmptab
  WHERE  (manager_id = empId)     -- Join condition
  ;
  

• Extract multiple lines using the technique of the cross join

  Hello.
  
  Can someone suggest a method to return 3 lines of a query when otherwise would return only one line?
  
  I am trying to reach the analog SQL logic to this topic-

  SELECT x.foo, p.id, p.name FROM people p CROSS JOIN (SELECT 1 AS foo UNION ALL SELECT 2 UNION ALL SELECT 3) x;

  Reason: I want a result three rows (n) force and use GROUP BY with case statements to create 3 levels summary.
  
  Here is a simple SQL logical expression that works for my setup - OBI

  SELECT
       "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".Repair_Number saw_0,
       "- Nx_CSDG0_Repair_Orders (Depot Repair Views)".SR_Operating_Unit_Name saw_1

  Hi CSeelig,

  The BI server uses the ANSI SQL standard. Then all the SQL that follows this specification in OBIEE will work.

  I did an example with intensification:
  http://gerardnico.com/wiki/dat/OBIEE/logical_sql/obiee_sql_densification

  You will see a cross join to make a densification.

• Pivot + cross join

  Hello
  
  I wrote the following query, which works very well:

  select * from
  (
       select
            to_char(SCB_OPENTIME, 'YYYY-MM') as curr_date,
            SCB_TASK
       from EM_DATA_MSR_SC
  )
  pivot
  (
       count(SCB_TASK) for curr_date in

  );

  Now, I need to apply a cross thereon join:

  select * from

      select 2, 'Open' from DUAL
  ) status;

  When I try to run this query, I get this error message:

  "STATUS"."NAME": invalid identifier

  However, SQL is supposed to have brought on a deep level table references.
  I'm doing something wrong?

  Hello

  If this is what you want, then you don't want a cross join. The inner join in the view online with no name is the only reference to beaches you need.

  with ranges as
  (
      select 0, 0 as mini, 20 as maxi from DUAL union
      select 1, 21, 50 from DUAL union
      select 2, 51, 300 from DUAL
  )
  select * from
  (
       select  r.mini,
            r.maxi,
            to_char (t.DAT, 'YYYY-MM')     as curr_date,
            t.NUM
       from      TEST     t
       join      RANGES     r     on      t.NUM >= r.mini
                      and      t.NUM <= r.maxi
  )
  pivot
  (
       count(NUM) for curr_date in
       (
            '2011-01',
            '2011-02',
            '2011-03',
            '2011-04',
            '2011-05',
            '2011-06',
            '2011-07',
            '2011-08',
            '2011-09',
            '2011-10',

            '2011-12'
       )
  )
  ORDER BY  mini
  ;
  

  Depending on your data and your needs, you might want an outer join, not an inner join, like this:

  ...     from          RANGES     r
       LEFT OUTER JOIN     TEST     t     on      t.NUM >= r.mini
                           and      t.NUM <= r.maxi

• [8i] need help with full outer join combined with a cross join...

  I can't understand how to combine a full outer join with a different type of join... is it possible?
  
  Here are some create table and insert for examples of database:

  ,     my_value     NUMBER

  ,     my_tab2 t2

  So, what I want, it's a full outer join of t1 and t2 on workstation and a cross join of one with the t3. I wonder if I can't find examples of it online because it is not possible...
  
  Note: I'm stuck dealing with Oracle 8i

  Hello

  The query I posted yesterday is a little more complex that it should be.
  My_tab2.workstation is unique, there is no reason to make a separate subquery as mt1. We can join my_tab1 to my_tab2 and get the SUM in a subquery.

  SELECT       foj.workstation
  ,       foj.sum_my_value
  ,       foj.wkstn_name
  ,       mt3.my_nbr1
  ,       mt3.my_nbr2
  FROM       (     -- Begin in-line view foj for full outer join
            SELECT        mt1.workstation
            ,        SUM (mt1.my_value)     AS sum_my_value
            ,        mt2.wkstn_name
            FROM        my_tab1   mt1
            ,        my_tab2   mt2
            WHERE        mt1.workstation     = mt2.workstation (+)
            GROUP BY   mt1.workstation
            ,        mt2.wkstn_name
                          --

            ,      0      AS sum_my_value
            ,      wkstn_name
            FROM      my_tab2
            WHERE      workstation     NOT IN (     -- Begin NOT IN sub-query
                                             SELECT      workstation
                                     FROM      my_tab1
                                     WHERE      workstation     IS NOT NULL

  She, exactly!
  The trickiest part is when and how get SUM (my_value). You could address the question of exactly what my_tab3 must be attached to a cross that's exactly what should look like the result set of the full outer join between my_tab1 and my_tab2 to. To do this, take your desired results, remove columns that do not come from the outer join complete and delete duplicate rows. You will get:

  workstation     sum(my_value)     wkstn_name
  -----------     -------------   ----------
  ABCD          30          WKSTN 1
  A123          35          WKSTN 2
  B456          0          WKSTN 3
  ????          5          NULL          
  

  So the heart of the problem is how to get these results of my_tab1 and my_tab2, which is done in the subquery FOJ above.

  I tried to use auto-documenté in my code names. I hope you can understand.
  I could spend hours explaining the different parts of this query more in detail, but I don't know that I would lose some of that time, explain things that you already understand. If you want an explanation of the specific element (s), let me know.

  Why 10 gr 2 we have error ORA-00918 (same self-join) and 11 g works, but the wrong result?

  Why don't you ask Oracle via a support request, it's a bug.

  You can't say he is working on 11g "but which gives bad result."  Clearly if it is to give a wrong result then it doesn't work.

  What happens on 11g is the fact that it runs without the exception of ambiguous column.  There are a few known bugs in the way SQL ANSI has implemented compared to the regular SQL Oracle syntax.  Oracle worked to correct.

  I don't have 12 c to test, but it may have already been corrected in this version.

• How create/update files when the original Version is based on a query of outer join?

  Hi gurus,
  
  
  I created a custom page where I use a table-style area where I question my VO records, based on a query of outer join. This query contains my table looks, where I would like to insert/update records, and joined the table of standard elements, which is external with my custom table.
  
  When I now question my files in the t, I have a record for each record in the table section, which is ok, but when I 'Refresh' some fields of my custom table and attempt to commit, I get the message "unable to complete the transaction on record. Cause: The record has been deleted by another user. "Action: cancel the transaction and re - query records to get new data.
  The reason why because a record is to be inserted rather than updating because in fact there is not yet in my custom table.
  
  The reason why I'm using the outer join, is because I don't want the user to create a record for each item one by one.
  There is no work around for this?
  
  Thanks in advance!

  Guy

  Hello
  You can try this.

  In your EntityImpl.java to extend OAPlsqlEntityImpl.

  Override the updateRow() method and coding your insert statement to insert into a table custom here.
  Don't forget, you must ignore the lines for which your custom table columns are null

• cross join?

  I was asked if the veiw (select what is wrttien to make the view) has a cross join and follwing some ANSI compliance. So my question is... as table 3 below is used by alias tp and same table3 is used by alias tp2... commandeer that be considered as a cross join?
  
  Sorry, I'm very new to SQL...
  

  select col1, col2, col3 from table1 t, table2 t1, table3 tp
  where
  ---
  ---
  ---
  AND tp.phs_id =
                        (SELECT tp2.phs_id
                           FROM table3 tp2
                          WHERE tp2.id = tsp.id
                           AND ROWNUM < 2)

  Published by: user11168115 on May 14, 2009 12:43

  Hello (and welcome)
  No, would not be a CROSS JOIN, since your alias tp2 JOINED tp (I guess you mean tp even if you have a TSP). A CROSS JOIN is where no JOIN condition at all is specified for a table (also known as the Cartesian product ), and if it's compatible ANSI SQL will actually be the words CROSS JOIN specified in the JOIN clause. For example:

  SELECT *
     FROM table1
   CROSS JOIN table2;
  

  Otherwise, non-compliant ANSI:

  SELECT *
    FROM table1, table2;
  

• Query SQL syntax - joins

  I hope it's a quick.

  I'm OK with standard inner joins that links the two tables, but what would the syntax to query three supports like this:

  tbl_Nominations

  NominationID (PK)

  Nomination

  LodgeID (foreign key to tbl_Lodges)

  tbl_Lodges

  LodgeID (PK)

  Lodge

  CountryID (Foreign Key to t/l_Countries)

  tbl_Countries

  CountryID

  Country

  Whereas for any given LodgeID I can show:

  Lodge, the appointment and the country?

  Thank you.

  Just to say that I figured it - left outer joins, no outer joins, so:

  SELECT * FROM nominations LEFT OUTER JOIN hosts designations. LodgeID = lodges. LodgeID LEFT OUTER JOIN continents we'RE staying. ContinentID is the continents. ContinentID

  gives me what I was looking for.

• 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)

  OCT 2012
  
  Is it possible I can join these two select statement above to generate a comparable result:

  Ann

  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

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

• How to get the inline query which is drawn from the TAB specific Application.

  Hi all I use 10.2.0.4.0 oracle version.
  
  I want to capture the sql that is raised in my prod database when an applicaton tab is hit as it takes about 5 minutes for the tab to be loaded. So is it possible, for the inline sql, which is the origin of the problem, directly from the prod environment.
  
  (Note: I looked through the browser session in PROD DB for the query, but there, I found a lot of meetings and a lot of requests, I do not know how to distinguish the session being created by the specific tab I hit).

  Please, please tell us that you have a Test environment? Log into that, then run a trace.
  No doubt you can either descend all test for a few miinutes and/or
  easily distinguish sessions on your Test System? That's exactly what the test
  the environments are for.

  The SQL execution will be the same - you can go try to find
  the root cause of the problem.

  Hi Tim,.

  In your request, you have just the dimensions? How about you have measure in this report and check if you still have the same error.

  I see your LTS settings well (as you have merged the individual facts in MDB). Generally, the query according to dimensions must go through setting relationships and so here, he must go through different facts well;). Could you post your request so that we can have a look?

  PX stuff, it's just the 'pipes' oracle uses to divide your table into pieces and the pieces of transformation. You don't have much control that beyond doing Oracle use parallel queries or not. I guess that you can specify a degree, but this isn't your problem, anyway. But if you're curious, PX is mentioned here. http://docs.Oracle.com/CD/B12037_01/server.101/b10752/ex_plan.htm

  Using index becomes a little more complicated with outer joins, because they return the rows that do not match the table conduct. If the index will be useful on the tables of conduct. It is possible to what I was looking to take advantage of the index because each row of the table is returned to the outer join. If you want to limit who then you need some sort of filter condition and an index on that column filter would be useful.

• Help of query SQL - inner joins and the separate results

  Hello
  
  ASP VB, SQL Server
  
  I have a structure of data base with 3 tables - users, albums and photos. each user has a identifier unique, each record has a unique albumid and also contains a column with the user name. each record in the photo has a unique id so that store the user name and the album in which the image belongs.
  
  I'm writing a query that returns a list of the albums for a particular user (based on a user name query string) and who will also bring back the id of the first record in the table for each of these albums photo.
  
  the closest I get is to run a query to select albumid albums where userid = varuserid with a join internal on the pictures table to remove the photo ID - problem I then it comes out all the photos from the photos table where userid = varuserid, so when I do a repeat region to display a list of albums for a certain user It produces a list of all the photos where userid = varuserid
  
  I really want to return just a list of ID album based on the username variable, but also to return the first record in the table of photos for each of these albumids
  
  I tried different combinations of inner joins, select distinct etc but no joy.
  
  any suggestion would be appreciated as am floundering here...
  
  
  
  
  

  First, you must define 'first' with regard to the photos. Is there a
  timestamp? They are numbered inside the album? Do you really care who is
  "first", or do you want simply a shot? You also neglected to indicate if they are
  empty photo albums have been allowed. I assumed that the empty albums are not
  allowed.

  Whatever you decide, the answer will be similar.
  SQL Server tends to get better results with joins with subqueries. You will have
  See such a written request more often with subqueries, and there isn't
  nothing wrong with that, but I'll use a join on a derived table. I have
  have not all column names (hint, hint), so I made them, but the
