• How to find the child level for each table in a relational model?

  Earthlings,
  
  I need your help, and I know that, "Yes, we can change." Change this thread to a question answered.
  
  So: How to find the child level for each table in a relational model?
  
  I have a database of relacional (9.2), all right?
  

  .
       O /* This is a child who makes N references to each of the follow N parent tables (here: three), and so on. */
      /↑\ Fks
     O"O O" <-- level 2 for first table (circle)
    /↑\ Fks
  "o"o"o" <-- level 1 for middle table (circle)
     ↑ Fk
    "º"

  Tips:
  -Each circle represents a table;
  -Red no tables have foreign key
  -the picture on the front line of tree, for example, a level 3, but when 3 becomes N? How is N? That is the question.
  
  I started to think about the following:
  
  First of all, I need to know how to take the kids:

  select distinct child.table_name child
    from all_cons_columns father
    join all_cons_columns child
   using (owner, position)
    join (select child.owner,
                 child.constraint_name fk,
                 child.table_name child,
                 child.r_constraint_name pk,
                 father.table_name father
            from all_constraints father, all_constraints child
           where child.r_owner = father.owner
             and child.r_constraint_name = father.constraint_name
             and father.constraint_type in ('P', 'U')
             and child.constraint_type = 'R'
             and child.owner = 'OWNER') aux
   using (owner)
   where child.constraint_name = aux.fk
     and child.table_name = aux.child
     and father.constraint_name = aux.pk
     and father.table_name = aux.father;

  Thought...
  We will share!

  Have you looked to see if there is a cycle in the graph of dependence? Is there a table that has a foreign key to B and B has a back of A foreign key?

  If you have a cycle, you have some problems.

  (1) it is a NOCYCLE keyword does not cause the error, but that probably requires an Oracle version which is not so far off support. I don't think it was available at the time 9.2 but I don't have anything old enough to test on

  (2) If you try to write on a table and all of its constraints in a file and do it in a valid order, the entire solution is probably wrong. It is impossible, for example, to generate the DDL for MY_EMP and MY_DEPT such as all instructions for a table come first, and all the instructions for the other are generated second. So even if NOCYCLE to avoid the error, you would end up with an invalid DDL script. If that's the problem, I would rethink the approach.

  -Generate the DDL for all tables without constraint
  -Can generate the DDL for all primary key constraints
  -Can generate the DDL for all unique key constraints
  -Can generate the DDL for all foreign key constraints

  This is not solidarity all the DOF for a given in the file object. But the SQL will be radically simpler writing - there will be no need to even look at the dependency graph.

• How to find the SID for DB Oracle 11g

  Someone installed a new database of Oracle 11 g on my machine. Now I'm opening "SQL Developer" and it asks username, password and sid. I don't know what is the SID for my case. How I know that?

  I checked the list of services in my machine. There is no service windows in my system named OracleService

  You mention that you are using Windows, but if you are and that you have installed the oracle database software and NO service like OracleService , then you do not have a database. But then, why the hell you you ask about this? If you do not want the database software, why don't you just go ahead and uninstall it? And how is it, someone can come and something on your server and have no idea about it?

• How to install the driver jdbc for sql server 2005 in sql developer 4.0?

  
  Hallo all

  I need to access the tables in a MS SQL Server 2005 database.

  The JDBC driver is possible.

  How to install this driver?

  Thanks a lot for your messages.

  Hello

  It's the documentation-

  Database: third-party JDBC Drivers

  The component drivers JDBC third party specifies drivers to use for connections to the third-party databases (non-Oracle), such as IBM DB2, MySQL, Microsoft SQL Server or Sybase Adaptive Server. (You don't need to add a driver for connections to Microsoft Access databases.) To add a driver, click Add an entry and select the path for the driver:

  For Microsoft SQL Server or Sybase Adaptive Server: jtds - 1.2.jar, which is included in the download of jtds - 1.2 - dist.zip

  To find a specific third-party driver, visit the appropriate site (for example, http://www.mysql.com for MySQL Connector/J JDBC driver for MySQL, http://jtds.sourceforge.net/ for the for Microsoft SQL Server and Sybase Adaptive Server jTDS driver, or search for Teradata JDBC driver to http://www.teradata.com/ ). For MySQL, use the driver in MySQL 5.0 not 5.1 or a later version with the version of SQL Developer 1.5.

  You must specify a third-party driver or install a driver using the check for updates feature before you can create a connection to a database to third parties of the associated type. (See the tabs to create connections to the databases of third parties in the Create/Edit/Select database connection dialog box).

  Alternative:

  As an alternative to the use of this preference, you can click Help, and then search for the updates install the for Microsoft SQL Server JTDS JDBC driver and the driver of JDBE of MySQL as extensions.

• How to find the rank lowest for each student using a Select query?

  Hey I'm having a little trouble here
  
  I have this table
  
  
  Student - Grade
  
  John - 8
  Richard - 9
  Louis - 9
  Francis - 5
  John - 13
  Richard - 10
  Peter - 12
  
  Shades may vary from 0 to 20.
  
  Name - varchar (50)
  Grade - wide
  
  I'm trying to generate a SQL search to search for each rank lowest for each student.
  
  So far, I did:
  
  Select s.name, s.grade
  s student
  where s.grade = (select min (grade) of student)
  
  The result of this search returns me only the rank lowest of all ranks posted above, which is Francis - 5.
  
  I want to find the lowest rank, but not only for Francis, but for all students in the table.
  
  How do I do that?
  
  Thank you in advance.

  Ok

  Now we head into analytical SQL:

  with student as (select 'John' name, 8 grade, 'fail' result from dual union all
                   select 'John' name, 13 grade, 'pass' result from dual union all
                   select 'Francis',     5 grade,  'fail' from dual union all
                   select 'Peter', 12, 'pass' from dual)
  -- End of your test data
  SELECT   name,
           MAX (result) KEEP (DENSE_RANK FIRST ORDER BY grade) result,
           MIN (grade) min_grade
  FROM     student
  GROUP BY name
  

  Please note that I passed ;)

• How to find the best log of SQL in the responses of the OBI?

  While I have an error by a request of the OBI in answers page, the error message in the result tab is usually not very useful, as:
  

  Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P:OI2DL65P
  State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 27005] Unresolved column: "Sales Facts Current Month"."Amount Sold (000) Current Month". (HY000)

  SQL Issued: SELECT "Sales Facts Current Month"."Amount Sold (000) Current Month", "Sales Facts"."Amount Sold", Calendar."Calendar Month Desc", Calendar."Calendar Month Name", Products."Prod Category" FROM SH

  I then go to the Session Monitor and click the view log. By doing so, sometimes, I got the complete sql statement. It is good and I can understand the problems. Sometimes, I have things like:

  -------------------- SQL Request:

  It is not enough that the selected tables are not entirely clear on. It appears like it find OBI the sql in the cache and process the request entirely.
  
  Is there a way I can force return OBI demand? Is there a way to get OBI newspaper the complete sql statement? This way I can copy the SQL to SQL * more and find exactly the problem
  
  Thank you.

  Physical SQL is not visible because it hits the cache.
  You can:
  (1) clear RPD physical cache and run the query again.
  or
  (2) copy the SQL logic, go to web Admin - number SQL - paste the SQL logic, then just change a setting or two, so it does not hit the cache. For example, to change a filter to Jan Feb... or just add a dummy column initially as select 1 or select 'a'... .rest of sql even.

  in this way, you can avoid hitting the cache and see the sql code (at the bottom of the results - view the journal)

  Make sure that you have enabled the option to cache presentation server and define the level of logging to 4 or more to see the details.

• How to find the exact motherboard for Satellite P100-347 model?

  Hello
  I hope someone could help me. I'm looking for a new motherboard for my computer toshiba laptop because it replaced needs.

  I own a laptop Satellite P100-347 of pspa6e-03302cen and have not been able to find this anywhere online forum. Although I found two suppliers of many motherboards of p100, they use numbers of alternative model in which I can't find anywhere in my documents or on the computer. The model numbers they use are something like A000008350 or a number starting with k. I'm sure that the supplier I found has the motherboard, I would need but I would need a list of all the numbers of the other party for my laptop, or a way to find the exact numbers. Any help on this is appreciated...
  Thank you

  To be honest I really don't think that someone here can offer you this info. As you know, this info is for internal use and you can try to get this info from service provider authorized in your country. Sorry, but I don't see a better solution, except to wait here and hope someone can help.

  Good luck!

  I'm playing a game that connects to live on steam. He asked my windows product key which I didn't, but I discovered how to get without going through it. I got about 5 + programs for giving me my product key number anyway. But I always get an error message. I checked it more than 10 times. Still does not work. Is it possible for a person to miscrosoft to give me or I can call and they can give me?

  Hello Elias1724,

  Steam ask the product key for the game and not your product key for the Windows operating system.

  Where did you buy the game to install it?
  You bought the game on Steam? If so, then they would need the product key.
  Have you received an email with a link to download the game?

  It is not your Windows product key.

• How to find the user oracle for a planning application search

  Hello
  I know how to take backup but I dnt seem to remember the user that I created in oracle to the planning application and there are many users that there are many applications on the sytem, how to know which is the user for a particular planning application
  Thanks in advance

  I would of thought you would name a name of data source with the same name as the planning application, it makes it a lot easier, the naming scheme of names with the same name also keeps everything the same.
  If you can not link the name of the data source for the name planning then you will need to look at the system of planning and HSPSYS_DATASOURCE and HSPSYS_APPLICATION tables, this allows linking by ID.

  See you soon
