  How the nested table that is stored in the database?
  The nested table column is stored with the table main or separate in the database?

  A nested table is a table that is stored in the structure of another table. It is used to support the columns that contain multivalued attributes.

  If you want to use the same type in multiple places, create them on a global scale and these will be discussed under 'Types'.

• How the repeating table inside a control valve?

  Hello

  Does anyone know how to make the repeating table inside a control valve in LabWindow CVI? I see that there is option for a Panel to scale content in resizing, but not available for a tab control. Any ideas?

  Thank you very much!

  Weiming

  I don't know, I understand what you're trying to do, but you can set ATTR_SCALE_CONTENTS_ON_RESIZE on each tab panel.

  GetPanelHandleFromTabPage (panelHandle, PANEL_TAB, 0, & tabPanel);
  SetPanelAttribute (tabPanel, ATTR_SCALE_CONTENTS_ON_RESIZE, 1);

  These numbers are the number of rows in each table (in other words, the 'SELECT COUNT (*) FROM countries' output would be 100)?

  If so, and if you're happy with an account may be estimated from the last time statistics were gathered, you can do something like this:

  SELECT table_name
  num_rows
  From all_tables
  Owner WHERE = 'SCOTT '.

  ;

  If you want the exact number at run time, you need dynamic SQL statements.  Here's a way to do it:

  SELECT table_name

  , EXTRACTVALUE (XMLTYPE (dbms_xmlgen.getxml (' SELECT COUNT (*) AS num ")))

  || 'FROM ' | owner | '.' || table-name

  )

  )

  , ' / LINES/LINES/NUM.

  ) AS num_rows

  From all_tables

  Owner WHERE = 'SCOTT '.

  ;

  Whatever it is, you get results like:

  TABLE_NAME, NUM_ROWS

  ------------------------------ ----------

  DEPT                                    4

  EMP                                    14

  BONUS                                   0

• How can I make sure that changes in a primary key (in the parent table) would also appear directly in the FOREIGN KEY in the child table?

  Forgive my question. I am very new to Oracle.

  How can I make sure that changes in the key primary supplier_id (concerning the supplier table) would also appear directly in the FOREIGN KEY (supplier_id) in the products table?

  Is that not all the primary key and FOREIGN KEY on?

  My paintings:

  I created 2 tables and connect to apply in the data base referential integrity, as I learned.

  CREATE TABLE - parent provider

  (the numeric (10) of supplier_id not null,)

  supplier_name varchar2 (50) not null,

  Contact_Name varchar2 (50).

  CONSTRAINT supplier_pk PRIMARY KEY (supplier_id)

  );

  CREATE TABLE - child products

  (the numeric (10) of product_id not null,)

  supplier_id numeric (10) not null,

  CONSTRAINT fk_supplier

  FOREIGN KEY (supplier_id)

  REFERENCES beg (supplier_id)

  );

  I inserted the following text:

  INSERT INTO provider

  (supplier_id, supplier_name, contact_name)

  VALUES

  (5000, 'Apple', 'first name');

  I expect that the supplier_id (5000) to the provider of the table also appears in the products table under key supplier_id having the same value which is 5000. But this does not happen.

  How to get there?

  Thanks in advance!

  Hello

  What is a foreign key in Oracle?

  A foreign key is a way to ensure referential integrity in your Oracle database. A foreign key means that the values of a table must appear also in another table.

  Ok!??

  What is now the right way to implement referential integrity in your Oracle database that the values of a table must also be included in another table?

  A foreign key referential integrity indeed enfore in ensuring that the value in the child table must have a corresponding parent key (otherwise you will encounter an error, as evidenced by "SomeoneElse"). However, it will never automatically insert a row in the other table.

  If you are looking for a solution that automatically inserts a record in the other table, maybe you should go for triggers:

  See:

• By the numbers, how do the list tables on the side?

  By the numbers, how do the list tables on the side? It used to be on the side, now it is on the top which is a huge pain.

  This changed in the transition from Numbers2.x too 3.x.

  Unless you explicitly removed numbers 2.x, it is always installed and usable on your computer.  You can locate it in the folder "/ Applications/iWork ' 09.

  You should be aware, that numbers 2.x cannot open files saved numbers 3.x - you can export files from Numers3.x back to Numbers2.x by using the item of menu numbers 3.x "file > export to > number ' 09»

  without using a loop, it is possible.using labview8.2

  Let's say that LabVIEW integrates a function to do it for you.  The underlying logic will use a loop.  Why?  Because it's a rather strange restriction put in place to prevent loops when you want to make an option that requires several almost identical iterations.

  Why are you trying to avoid using loops?

  Let's take a look at the code that can do what you ask.  Then we'll take a better look at it, and why we want to return to the question in bold?

  

  This will take your picture, splitting one line at a time, use the table 1 d inverse function (which will run an inner loop) on each line, build the lines in the 2D table and the output result.

  Now, what happens if you want to add a fourth row of this table 2D?  You must descend again to the same logic, wiring in the line concerned, extend the table construction, etc.  This could be something, you can manage.  But what happens if you want to extend it to a table with 100 rows?  Now, the work happens to be a little more and the code becomes essentially impossible to read.  You don't get any value here avoiding the loop.

  Let's take it a bit further.  What happens if you want to work with arrays of variable size?  Now, what will you do?  Your code is designed to work with a table size (and rather awkward doing).

  So we go back to the same question that we had this time together.  Why, exactly, you try to avoid loops?  Doing this without a loop is bad programming.  Don't limit yourself to bad practices to solve something that can easily be manipulated in a loop.  Write the code you maintain, scale and read.  If the loops are the best option, use them.  You're basically saying ' how can I use this screw if I don't want to use a screwdriver?  Of course, you can nail the it.  But stop being stupid.  Use the tool to the job.

  You can certainly use formula node for it. What you would do is to create a constant for the lookup table.

• How to configure the partition table for SSD?

  Drive: 32 GB SSD

  I accidentally delete without backup partition table information and would like to know how to put the partition table, I can access the tools of partition table, but do not know how to define.

  Does anyone have any suggestions?

  Thanks in advance for your suggestions

  Hello

  Thanks for posting your query in Microsoft Community.

  The SSD could be seen in the disk management window, and you could name and set up as another hard drive internal. To create a partition or volume on a hard disk, you must be logged in as an administrator, and there must be unallocated disk space or free space in an extended hard disk partition. To repartition your hard drive, please consult the following link and check if it helps.

  I can I repartition my hard disk?

• How to delete several lines in the details Table with PRIMARY KEY = ("VID", "LINEITEM")?

  Mr President

  My worm Jdev is 12.2.1.

  I have master tables / details.

  I have 2 lines for each PRIMARY KEY = ("VID", "LINEITEM") as below in the Details table.

  

  Please help how to get a button on a jsf page to remove these two lines at a time.

  Concerning

  So, in your app (data model) module, you have a master relationship / typical retail:

  

  And the relationship between them is based on some ViewLink

  Now go to the ViewLink, relationship, accessor.

  Take a look at the Destination accessor.

  Generate accessor object to check and give a name Acessor

  

  Then go to the master VO, Java and Include accessor, the class generate a display line:

  

  Go to the class view Java generated line, you'll find a method with the name of the accessor of the previous step, in the form of:

  public RowIterator getYourDetails...or_whaterever_IsAccessorName..() {
  }
  

  Now, in the same Java class, write the following Java method:

  public void removeDetails(){
    RowIterator details = getYourDetails...or_whaterever_IsAccessorName..(); // it is RowIterator over all details
    Row r = details.first();
    while (r != null) {
        r.remove();
        r = details.next();
    }
  }
  

  This method on the Cilent export line Interface:

  The new logical table is right click on the MDB itself, for the join you generally in the business model diagram (again right click on objects).
