Need clarification on the ANSI joins

• Need help with the ANSI Join syntax

  Version: 11.1.0.7
  
  I have my select statement that returns 3000 lines and looks like
  

  select ..
  from tab1 a,tab2 b,tab3 c
  where a.c1=b.c1 and
  b.c2 = c.c2(+)
  and ...
  group by
  ..

  I want to convert it to ANSI SQL, because it must be able to Hibernate, and the developer says that Hibernate include only ANSI SQL. I tried something like
  

  select ..
  from tab1 a INNER JOIN tab2 b
  ON a.c1=b.c1 
  LEFT OUTER JOIN tab3 c
  ON b.c2=c.c2
  where ...
  group by
  ..

  I felt bad and it turned out to be the same. It returns no rows. Please help with the correct syntax.

  I'm not sure, sorry, because it's certainly the ANSI equivalent to the non-ANSI.

  Would you have examples of queries and data that you can reproduce the problem with, and that we could analyze?

  Published by: Seanmacgc on July 15, 2009 12:48

  If there is no Clause WHERE conditions in the original that are included in the ANSI version of the query in the WHERE Clause for the EXTERNAL table itself joined, then that could transform the JOIN JOIN internally, that is, all the filters on the EXTERNAL joined table should be included in the JOIN predicate - IT (b.c2 = c.2 AND c.c3 = 'X').

• use the ansi join syntax

  From what I've been reading is preferable to use the new syntax (don't know how is it news)

  The ANSI join syntax was new to Oracle in Oracle 8i in 1998 - that is 15 years old.

  It can produce more readable code and is also much more readable and less human-source of errors for outer joins.

  The ANSI format allows an outer join between several tables in a way the old (+) syntax specific to oracle does not and introduced the JOIN FULL OUTER you should use very rarely.

  You should not use NATURAL JOIN in code - add columns not related to the tables involved can give very different results.

  There have not been important bugs for ANSI joins in Oracle from Oracle 10.2 set up about 8 years ago.

  As Paul says, the part on should be the criteria to join between the tables. Did clause should be the filtering of the joined tables.

  So assuming start_date and end_date in_property_id are variable

  SELECT resv_num, unit_date

  OF p_resv_unit ru

  INNER JOIN p_pm_unit_night pun

  ON pun.resv_unit_id = ru.resv_unit_id

  WHERE pun.property_id = in_property_id

  AND pun.unit_date BETWEEN start_date AND end_date

  AND pun.pm_unit_num = cvUnitNum;

  If start_date and end_date are the columns of p_resv_unit the query would be:

  SELECT resv_num, unit_date

  OF p_resv_unit ru

  INNER JOIN p_pm_unit_night pun

  ON pun.resv_unit_id = ru.resv_unit_id AND pun.unit_date BETWEEN ru.start_date AND ru.end_date

  WHERE pun.property_id = in_property_id

  AND pun.pm_unit_num = cvUnitNum;

  Inner join queries work with criteria in the wrong place, but they are harder to read. Outer joins do not work unless you put the criteria in the right place.

• Need clarification on the explanation of size on a DVD

  Hi all

  I did a certain DVD so far with yet. Some are as short as 1 hour, some are as long as 2.5 hours. I continue to expect again to say "too video for the project"... but is not. I look at the menu "Generate" and he always says the same thing in 'disc info '.

  Here is a screenshot:

  

  This project is of 2 hours 25 minutes. Is still somehow force on this 4 GB drive? Does this mean that certain quality will degrade? I bought a double disc burner layer thinking that soon I have to use it but so far I have burned projects that are big enough on my single layer.  Yet tell me when the project is too large for single layer?  Here is my system info:

  System: Mac OS X, version 10.6.8

  2.66 GHz Unknown processor

  Total physical memory: 8 GB

  Adobe still serial number: 976xxx

  Product version: 5.0.0.508

  First Media layer Version: -.

  Devices Blu - ray installed:

  None

  Installed DVD features:

  HL-DT-ST DVD - RW GA11N (Firmware KA19)

  Thank you guys!

  The answer will vary according to which challenge the material is (much higher than motion natures/low datarates needs movement), and the importance of quality is in your project.

  A rule of thumb is 2 hours is OK for a single layer, but some time at higher quality projects will be max on a disc single layer.

  And Yes, your 2 hours the project will be compressed to a high data rate (best quality) if still has two layers.

  Thanks for posting the CREATE TABLE and INSERT.
  It is more useful if you post the code that can be run without modification. You did not semicolons after INSERTION instructions.

  Three questions:
  (1) I don't want to return results where table_name = "table1". I can't get this to work.

  What have you tried? Post your best attempt.
  Here's one way:

  SELECT    u.table_name
  ,        u.column_name
  ,        c.constraint_name
  FROM             user_tab_col_test      u
  LEFT OUTER JOIN  all_cons_columns_test  c
                          ON    u.table_name     = c.table_name
                 AND   u.column_name     = c.column_name
                 AND   c.constraint_name IN ('primary')
  WHERE       u.table_name     = 'table1'          --  *****  NEW  *****
  ORDER BY  u.table_name
  ,            u.column_name
  ;
  

  You would not put this condition in the clause; who controls what is considered as a match between the tables, and "u LEFT OUTER JOIN c" means show all lines of u, even if they do not have a match in the c.

  (2) is my proper request and this is the best way to return my desired results? For example, I want all of the columns of user_tab_col_test and I want to only display the constraint_name from all_cons_columns_test argument if the argument constraint_name = 'primary '.

  Basically, this application is very well.
  It displays all the columns of user_tab_col_test; missing data_type. Just add u.data_type to the SELECT clause, or change the SELECT clause

  SELECT    u.*
  ,         c.constraint_name
  

  (3) will be the synatx be the same if I need to join a third table to all_cons_columns_test?

  Do you mean "" * add * one-third * column * to all_cons_columns_test '? "
  It depends on what results you want. Post new CREATE TABLE and INSERT and instructions the results you want new data.
  Most likely, the basic structure of what you've written will remain exactly the same.

  Thank you

  David,

  Two things. First, it makes it much easier if you put '{code}' (without quotes) around your SQL when you publish:

  SELECT rowid "EDIT", attr_code,ATTR_ATCL_CODE "Atcl Code", attr_description, attr_atcl_code,
                  attr_abbreviation,
                  attr_include_short_desc "Include short desc",
                  attr_include_long_desc "Include long desc",
                  attr_attr_type "AttrType", rowid "DELETE"
             FROM t_new WHERE EXISTS (SELECT 1 FROM APEX_APPLICATION_PAGE_IR_COND WHERE APPLICATION_ID = :APP_ID AND PAGE_ID = :APP_PAGE_ID AND CONDITION_ENABLED = 'Yes'
  AND APPLICATION_USER = :APP_USER) ORDER BY attr_description;
  

  If the spacing still needs work, it is a little easier to read.

  Second, your query exists clause checks just a State on, without checking the condition type. Without checking, I guess either APEX creates at least an inner State, or that your IR has a default condition on it (other than a filter). Try to add the constraint condition_type to your where clause to see if that solves it.

  Also, I noticed that you don't have additional code to get the report_id. It should not be necessary, because there are currently only supported for an IR by page, but you asked what are the differences.

• Need Clarification on the casting in Java

  Here's the question,
  
  class {Alien
  String invade (short ships) {return 'a little' ;}}
  Invade the string (... brief ships) {return 'a lot' ;}}
  }
  {Defender class
  Public Shared Sub main (String [] args) {}
  System.out.println (new Alien (.invade) (7));
  }
  }
  
  The answer is the compilation fails because the 7 argument must be cast for short.
  
  Now my doubt is that more short is 16 bits in Java, 7 can be stored in a variable short, why do we need to cast?
  If someone can clarify it?

  5.3 reading here:

  http://Java.Sun.com/docs/books/JLS/second_edition/HTML/conversions.doc.html

  The above explains why the narrowing conversions do not apply when choosing a method to call (from possible overloads).
  What they don't say is why they do not have an exception for the literal arguments, like 7.
  I guess that's for simplicity and consistency.

• Need clarification on the calculation IF statement script

  Hello guys,.

  
  

  Usually in my other projects, I used IF statement while writing scripts of calculation by mentioning some members in the LHS and assigning certain values to this member on the RIGHT side. But rrecently in one of my projects, I came with a new typical script which involves the IF function.

  Please find the script calc which is present in the system already below. Inviting you to give some idea on what it executes.

  Consider that I have seven Dimensions called account, Time_Period, JOBS, management, Source, Centre, matrix.

  DIFFICULTY ("no job, Apr)

  Fix (@UDA ("Account", "allowance"))

  DIFFICULTY (@RELATIVE ('A domestic', 0), @RELATIVE("Source A",0), @LEVMBRS("Centre A",0))

  SET CREATENONMISSINGBLK

  "Ratio" of the size of the matrix

  (

  IF ("BegBalance->" no branch "->" no Centre "->" input "of the size of the matrix == 1")

  'Ratio'->' value Allocated ' account dimension;

  ELSEIF ("BegBalance"-> "no branch"-> "No Centre"->"Input" == 2)

  'Ratio'->'value UnAllocate' account dimension;

  ELSEIF ("BegBalance"-> "no branch"-> "no Center"-> "Input" == 5)

  'Ratio'->'value Midalloc' account dimension;

  ENDIF;

  ON THE OTHER

  #Missing;

  ENDIF;

  )

  Here in the above script, after the condition of the IF statement, they did not mention any LHS = 'Ratio'-> "value Allocated"; but directly affected 'Ratio '->' value Allocated '... This means it applies to anywhere in the cube?

  Please explain.

  It is attributed to "Ratio", because it is the Member that you opened a calco block for with:

  "Ratio" (...)

• Need clarification on the export of an mxf with 8 audio channels Windows 7 first Pro CS 6.0.3

  I have read and followed the many discussions on this subject. I am grateful that the broadcaster has the patience to endure my test files. Yet once the broadcaster rejected my fifth test file, I am asking for help.

  I've set up a channel Master 8. Channel 1 is a frazzled left stereo mix. Channel 2 is a frazzled right stereo mix. Channel 7 is a copy of channel 1. Channel 8 is a copy of channel 2.

  The broadcaster said that there is no sound on channels 7 and 8, although I see these channels in my mixer as with audio. Posted you a screenshot of my setup of editing and mixing.

  Please tell me what I'm doing wrong. Thank you!

  

  Bring your export in PP.  If you add to that a sequence and see audio 7 and 8, then the problem lies in the diffuser.  If you don't see not audio it, post back with a screenshot of your export settings.

• Need Clarification on the deployment of customizations OFA

  Hi all
  
  I'm new to OAF and I have a question about the deployment of customizations in the OPS.
  
  The customizations are overwritten?
  
  If I make a change to the MyRequisitionsPG(for example), the MyRequisitionsPG.xml will contain the information together?
  
  As... Here is my scenario:
  
  I have a forum for production and two instances of development.
  
  The MyRequisitionsPG for the production and DEV1 are different.
  
  If I make changes to the DEV1 instance and deploy in my prod, how the page will look like? Will be my prod page crushed with all the other changes.
  
  MyRequisitionsPG (Prod) has a currency field.
  
  MyRequisitionsPG (DEV1) has date and currency fields.
  
  If I make changes to MyRequisitionsPG (DEV1) money on the ground and to deploy the Prod page, will be the date the field also comes in the prod?
  
  Thank you

  MyRequisitionsPG (DEV1) has date and currency fields.

  If I make changes to MyRequisitionsPG (DEV1) money on the ground and to deploy the Prod page, will be the date the field also comes in the prod?

  Yes, it will come to the Production instance as Dev1 page.xml is containing the date files and when you deploy that it will appear here.

• The ANSI syntax for the join 4 tables-is this correct?

  Hi, I'm new to these forums and I have looked everywhere and cannot find the syntax and examples on how to join the tables 2 and 3 using the ANSI standard, but I need to reach 4. For a traditional join, it would be:
  
  SELECT a.two b.one, b.three, b, a.one, d.seven
  Tablea, tableb b, c in tablec, deposited d
  WHERE a.one = b.one
  AND a.two = c.two
  AND c.six = d.six;
  
  Here are the tables:
  
  TableB
  one
  three
  four
  
  TableA
  one
  two
  
  TableC
  two
  six
  
  deposited
  six
  seven
  eight
  
  Anyone know how to do this by using an ANSI join or have all of the resources that can guide me in the right direction. I don't know if I wanted to join three tables, it would be:
  
  SELECT a.two b.one, b.three, b, a.one, c.six
  FROM tableb b JOIN tablea one WE b.one = a.one JOIN tablec c ON a.two = c.two;
  
  so join a fourth would:
  
  SELECT a.two b.one, b.three, b, a.one, d.seven
  FROM tableb b JOIN tablea one WE b.one = a.one JOIN tablec c ON a.two = d JOIN filed c.two ON c.six = d.six;?
  
  Is the above correct or is there another way to do this, use an ANSI join?
  
  Published by: user1076466 on October 17, 2009 17:40

  Hello

  your JOIN looks good,

  "FROM tableb b JOIN tablea one WE b.one = a.one JOIN tablec c ON a.two = d JOIN filed c.two ON c.six = d.six" you get a different result set?

• Need a Clarification on the installed component and run Simulator Configuration

  Help!

  I need clarification on what the plugin Eclipse is telling me. There are two parameters that are confusing me. For components installed (found under preferences/Window/BlackBerry JDE/Installed Components), I have a choice of 5.0.0 4.7.0,4.6.1, 4.6.0 4.5.0 and 4.3.0.

  Depending on which component I select when I go in the tab Configurations.../Simulator/course walk, I see a different mix of devices.  In all cases, there is a default Simulator.

  Initially, I assumed that each JDE component supports a mixture of different devices, and that is it compiled correctly, I would be assured that the app would work for all devices on the tab run Simulator Configuration.  In my tests, I found theopposite.  I also assume that, for each component of the JDE, there is a 'default' Simulator that was representative of all devices in the drop-down list run Configuration Simulator.  In my tests, am not sure what actually represents the Simulator 'by default'.

  Can someone clarify how to JDE and Configuration simulators run installed interact and a developer show how to ensure that their application is running on a mix of devices?

  When I finally get to the point where I am ready to deliver, what are the points of decision of installation?  Is it enough to simply require a specific version of an operating system (for example 4.7?) or do I have to create a grid and check the two model number and version of the operating system?

  Thanks for your help.
