  Can someone tell me why I get this error?

  You get it because dims_t is an array of OBJECTS - not a table of scalars. But your SELECT statement returns scalar.

  There IS NO such object, named "dimension_id"; It is an ATTRIBUTE of the object DIM_O. DIMENSION_ID is a SCALAR which, as says the exception, is a "No nested table element; If you cannot select/Update lines of it.

  What you do is equivalent to the following:

  DECLARE

  dims_t dim_T;

  number of dim_id;

  dim_o design;

  BEGIN

  Design: = dim_o (3, 'ghi');

  SELECT DIM_O (DIM_ID, LABEL) BULK COLLECT INTO table DIMS_T (d_o);

  end;

  /

  PL/SQL: ORA-22905: cannot access the rows of a table not nested element

  This SELECTION is trying to design it as a table when it's a SCALAR - so the same exception you get.

• How to integrate the structures of different tables in different databases?

  Hello
  
  I am new to oracle... well help me with the below question...
  
  I have the same set of attributes linked together (a, b, c and d) in two different databases A and B.
  
  The structure of the tables at the same time the database are different, but they carry the same attributes in the same relationship.
  
  I have to integrate these attributes to object unique db such as any update to the base tables updates my object. How can I do this and what object will be useful?
  
  
  Thank you

  Hi Arun,

  Then as you say they are of different databases, we can create a link between the databases and
  can create view based on the Tables.

  (i.e.) if the data in the base table changes the data in the view should also change in real time.

  Arun, of course, the view will also change in real time, because the view is nothing more than a virtual table.

  When you query on a view, he questioned the details of the * "Base Table" * only. If the data will be updated, i.e.
  existing in the Base Table.

  Thank you

• How to compare the structure of multiple tables... have just TOAD & CAULK

  Hello
  
  Several times, I get a request to load the data in the tables of one schema to another. But before doing that I need to compare the structures of tables in the source and target schema.
  
  How can I do? The list of tables to continue to change every now and then. A TOAD there is no option to compare a selected table list. Comparing schemas whole is not an option before me that patterns are too huge and it takes a lot of time to do the level schema comparison.
  Note This is a client machine, and we are not allowed to install any s/w.

• pointer to the structure within a structure in LabVIEW

  I have not used the library feature LabVIEW call very often, so I quickly found myself on a problem that may, or may not, be easy to solve (for someone in C code).

  Calling a dll that requires a pointer to structure as input. This I can provide by creating a cluster and using "Adapt to the Type" for the dll call input terminal. It passes a pointer to the cluster (structure) of the dll. However, the structure is supposed to contain pointers to other structures.  So now I'm stuck because I don't know how to create LabVIEW clusters that contain pointers to other poles of LabVIEW.

  Is it still possible?

  In the source file, the definition of the structure looks like this:

  typedef struct DmtxEncode_struct {}
  int method;
  the int schema;
  int sizeIdxRequest;
  int marginSize;
  int moduleSize;
  int pixelPacking;
  int imageFlip;
  int rowPadBytes;
  DmtxMessage * message;<-- pointer="" to="" another="">

  DmtxImage * image;<-- pointer="" to="" another="">
  DmtxRegion region;
  DmtxMatrix3 xfrm;

  DmtxMatrix3 rxfrm;

  } DmtxEncode;

  My own experience with it is limited, but a pointer is basically just a number that represents an address in memory (a number of 32-bit in a 32-bit system).

  Depending on the function you call what with the pointer, you might be OK with him giving even a null pointer, but because you have no way to know with certainty what the function does, or will in the future, you should give the correct pointer.

  How do you do that? Well, you need get the pointer to the relevant structure and for that you will need to allocate the structure. If the DLL you are using has a function that allocates memory for the structure and returns a pointer to it, you're in luck - take this pointer and put it in the cluster. If it doesn't have such a function, I think you need to write and compile a c yourself.

  That said, others with more experience could have a simpler solution.

• Problem accessing the service within my Document class

  Hello
  
  I have a Document class that dynamically adds a MovieClip to my Florida the MovieClip in the library FLA and has "Export for ActionScript" installation for him and that's how I access the My Document class MovieClip.
  
  The problem is that when the MovieClip is finished (he has a scenario animation and a stop() method applied to the last frame of the animation), I want him to call a function that is placed in my Document class, but simply call the function (for example displayEnterButton()); an error of...
  
  1180: call to a method may be undefined displayEnterButton.
  
  Can anyone help here, I'm sure it's a simple problem to solve.
  
  Thank you very much!
  
  Kind regards
  M.

  Hello

  I managed a work around that.

  Basically, my Document class, after the code that adds the MovieClip to the display list, I then put in place since a timer that called a function every 100 milliseconds. This function would then check the current image of the loaded MovieClip. If the current framework of the MovieClip is equal to the last frame of the MovieClip I know animation had finished and calls the following function that I needed.

  I pasted the code below in case anyone was interested...

• Node property of a control inside the cluster within a table

  I created a control that has a cluster to a Boolean, a string, and a digital.  Then, in my front, I created a table of these custom controls.  I wish I had access to the property of the controls inside the cluster in the table.  That is to say, I want to change the color of the Boolean or blinking, or "disable and gray" text box.  I think I'm on the right track, or maybe I'm on the wrong track.  I joined and example VI (testtray.vi) and control that I use (UUT_Display.ctl).  Please excuse the use of a flat Structure of the sequence, I know it is bad programming practices, but I just wanted to throw something together.

  Any help would be appreciated.

  Kevin

  Items in a table can have different values, BUT each element of the table share the same properties.

  "Blink" is a property when you make one in tha table blink you will all Flash.

  This restriction does not apply to clusters.

  So in theory, you could develop an XControl that has a data type is an array, but the display is actually a cluster that resembles a table. But write an XControl is not a trivial task.

• How to access the rows in a table

  Hi Experts,
  I am a newbie to Oracle Forms. I use a tabular form that has 5 lines. I have an Insert button and clicking on it, I have to insert all the lines in the form of database. My question is how can I access 2nd, 3rd and other lines of tables inside my PL/SQL block.
  
  Look forward to hearing from you soon.
  
  Thank you

  Hello and welcome to the forum,
  If I understand, you have non-database block in your form and insert the record-by-record button. If the above code is fine but slight change just use the built-in function NEXT_RECORD inside the loop, otherwise it will get stuck on the first record as...

  LOOP
    ...
    EXIT WIEH ...
    NEXT_RECORD; -- Just add this built-in to move cursor to the next record in tabular block.
  END LOOP;

• How to get the ID within a table?

  Hello
  Suppose that a table has first ID column that stores the unique ID in this format: P000001, P000002, P000003... and so on.
  How can I get the next value via query? After obtaining this insert query ID will be applied.

  Just use an Oracle sequence and consult nextval.
  You can apply the format as follows:

  SQL> create sequence my_seq;
  
  Sequence created.
  
  SQL> select 'P'||to_char(my_seq.nextval, 'fm000000') new_id from dual;
  
  NEW_ID
  --------
  P000001
  
  SQL> select 'P'||to_char(my_seq.nextval, 'fm000000') new_id from dual connect by level <= 5;
  
  NEW_ID
  --------
  P000002
  P000003
  P000004
  P000005
  P000006

• To access the Tables using DB link.

  Hello friends,
  
  I have an env development and production.
  
  I created a public link to DB developing say mylink.
  
  Trying to access the development of production table using the following command say to access x table
  
  Table DEV to access the PROD x using dblink
  
  Select * from x@mylink;
  
  Got the error like:
  ORA-02019: description of the connection to the remote database not found
  02019 00000 - "description of the connection to the remote database not found"
  
  Any idea on why this error is coming...
  
  Thank you/kumar

  I have an env development and production.

  I created a public link to DB developing say mylink.

  Trying to access the development of production table using the following command say to access x table

  Table DEV to access the PROD x using dblink

  Select * from x@mylink;

  You try to run the query in the database of PROD. This query uses a DB link that points to the DEV database.
  Very simple to understand: as you use the LINK DB in the PROD database, obviously it should be in the area of PROD... right?
  Imagine you use a PROD ("DBLINK") object and it does not exist here. I have it?

  SELECT * FROM x@mylink;

  Here,
  x database DEV table
  myLink - DB LINK in the database of PROD (pointing to DEV)

  Please try this.

• To access the buttons in the table

  Difficulties with certain codes, Im trying to access the buttons in my table, but cant seem to figure it out.

  my intention is to trace the im button pressing.

  Here is my code

  var btns:Array = [bk_btn, red_btn, blu_btn, brw_btn, purp_btn, orn_btn, ylw_btn, grn_btn, wht_btn];

  var currentClip = "";

  for (var a = 0; a < btns.length; a ++)

  {

  inclinometer [a] .addEventListener (MouseEvent.CLICK, colorbtnEvnt);

  }

  function colorbtnEvnt(e:MouseEvent):void

  {

  trace ("a");

  }

  assuming that these objects in btns exist, use:

  var btns:Array is [bk_btn, red_btn, blu_btn, brw_btn, purp_btn, orn_btn, ylw_btn, grn_btn, btn wht_];.

  var currentClip = "";

  for (var a = 0;

  {

  inclinometer [a] .addEventListener (MouseEvent.CLICK, colorbtnEvnt);

  }

  function colorbtnEvnt(e:MouseEvent):void

  {

  trace (e.currentTarget.Name);

  trace (BTNS. IndexOf (e.currentTarget));

  }

• to access the items in tables: confusion

  Hi, to access the items in a table is fundamental, but I am confused because I thought that you should use getChildAt (i) in a loop etc to access their "do something for them." However, I have a code that does not use getChildAt - it simply loops through the table. So why should I use getChildAt if I do ' t need?

  most of the stuff you said is incorrect or starting point.

  It is really very similar between the tables and displayobjectcontainers except the two can be used to browse a few displayobjects.

• Get all the rows of a table control

  Hi all

  I have a table with a column control. What function can I use to extract all lines? I have to go row by row and read each line or is it possible to do in a function?

  Thank you

  Kanu

  Assuming that Garay in the column have all of the same data type, you can retrieve the entire column with a single statement:

  GetTableCellRangeVals (Panel, control, VAL_TABLE_COLUMN_RANGE (1), array, VAL_COLUMN_MAJOR);

  The array passed must be large enough to recover all data. Alternatively, you can replace the VAL_TABLE_COLUMN_RANGE with the appropriate statement of MakeRect macro. In the event that your table was built of dynamically, you can get the naked, imber of lines using GetNumTableRows and size your table accordingly.

  The above macro is defined in userint.h as well as some other useful macros that can be used to access the data in a table.

  There are a few precautions to be taken in the case of string values or a certain type of cell (ring, combo box, button...) that are described in the hell of the function.

• Returns the name of the object in a table

  Hello

  I received the canvas of the objects stored in a table. Each painting has its name property.

  Is it possible to return a specific name?

  Actually I need an index number of this table, where I spend a name property of the object within this table (the name is taken from the event). Something like this:

  x = array.indexOf (canvasName = event.currentTarget.name)

  Why can't you just to target the instance?  It's enough to tell the difference between different objects.

  x = array.indexOf (event.currentTarget);
