Size of table

• Reg: size (conceptual) table-

  Hi Experts,

  I have a conceptual doubt about the size of a table.

  Tell - we got 500 k. I can store them in a table unique (say "table_x") containing all the lines.

  Is another way they can be stored in 5 tables (say 'table_x1', 'table_x2'... "table_x5") each holding 100 k records.

  So, which of the above data-storage-strategies will consume more space?

  My understanding is that-

  While creating a table, on a bigger picture, he uses segments. Say the segment size = 32K

  Table_x guess that consumes - 25K

  So, in this segment, left out space = (32-25) = 7K

  In the other approach, assume that each table takes 5K and due to some reasons the other (32-5 = 27 K) space remains unused.

  AFAIK, size of tables is calculated by the SUM of the areas of segment. Right?

  Please advise, correct if I am wrong anywhere.

  Thank you and best regards,

  Well, the problem is that you think that table is like the pizza box and lines are the pieces of pizza in the box when in fact it is the only pizza that you have in the database and there is no container for it. If you divide 100 GB of space in one go using a single segment or 10 segments of 10 GB each, you always set 100 GB of space only. There is nothing which contain these 10 pieces in itself which could devote additional space compared to the creation of a single segment of 100 GB. The example is not correct. It won't happen will be assigned to you a 100 GB space at once. Oracle allocates extents for this purpose only that you won't be wasting space. Your given scenario would occur when you have a segment or segments N created to allocate the necessary space and now might be to delete the data. It would create the space that would be unused but which would also be taken in charge by the LMT.

• Exact size a table takes

  Hello
  
  Can someone show me how to get the EXACT size a table currently occupies.
  
  
  Thank you.

  Heres something I've implemented for a client recently who wanted the object sizes, it breaks down the by object type (tables, indexes, lobtables, lobindexes) and see the percentage against total db size used in the segments... throw a table_name in if you want to limit the search... to remove the commentary on the inscription 'account' below to exclude all smaller then 50 MB

  as noted above, the blocks are different, but its close enough. could get some use out of it.

• Reset do default sets a size of table to zero?

  What is the function reset 2D game table size to default to zero? Aid is not explicit on this.

  Otherwise, what is the best way to set a table 2D zero size?

  The "it takes less time to try just to post a message asking if it is": the answer is Yes. But only if the default value is an empty array to start. Obviously.

  Wire a constant empty array to your choice of a local variable or a node of 'Value' property, in view of the elimination of any potential race condition.

• Generate several plots according to the size of table

  Hi all

  I'm relatively new to LabView and I read several threads that are similar to my problem, but I don't know how to implement it yet.  Basically I have a large table that stores the raw data read from multiple text files.  This large painting size would vary based on the number of text files generated by a data acquisition system.  I would like to draw each line of the table a new field.  Instead of manually wiring, is there an easier way around?

  Thank you

  Lynniz,

  If you need a separate chart for each parcel then can determine you at least in advance what the maximum number of locations could be and show/hide your graphics programmatically based on data. All the graphs could be in a Subvi that appears separate from your main application window, or you could use a secondary.

  I'm just brainstorming here. There could be a more elegant way to do it, but the graphic masking that already exist is the only thing I can think of right now.

• Dynamically adjust the size of table control panel

  Hello

  I have a combo box control that I drag within a table.

  Since my request depends on the size of the initialized array, I'm having a problem with the car, adjust the number of items to display on the control panel.

  Say for example, I wanted to have 4 zones of drop-down list on my table, I drag the table to show the 4 combo boxes.

  The problem is that if I wanted to change this moment of execution at 2 or 6 elements, it still shows 4 items in the control.

  Is there a way to adjust based on the number of items?

  I found it... must be a day tired... Since the solution is too simple

• Edge of metering size buffer/table problem (VC ++)

  Hello

  Accidentally, I posted this in the multifunction DAQ forum so forgive me for posting this again here.

  I'm trying to make an edge stamped with PCI-6115 of counting for the application that I'm developing.

  Ideally, I initialize a buffer array, then use a sample clock time and acquire the values of a counter which will then be stored in a buffer.  After a number of samples, I would then use the DAQmxReadCounterU32 function to extract this data and perform calculations.

  However, windows gives me an error when I try to initialize the size of the stamp of table is larger than 255001, I need 264000 +.

  Essentially, it seems that only this part of the code to execute:

  error int = 0;

  TaskHandle taskHandle = 0;

  TaskHandle taskHandleCtr = 0;

  given uInt32 [260000];

  After trying initialize the array of uInt32 my program crashes saying there was an error with my exe with a popup asking me if I want to send an error report to Microsoft.

  That would be a problem of windows not afford to allocated more 255000 32bits samples for this table?  If so how can I put the table on the memory embedded amount?

  Sorry guys, it actually had nothing to do with the DAQ card.

  He was apparently C++ that limits the size of the array that I called him, which was the traditional "int a [size]".

  I used this rather to solve my problem:

  int * a = NULL;
  a = new int [10000000];

  Problem solved.

  Sorry for posting in the wrong forum and thanks to all who read this.

• Format mask for the size of table cells

  Hi all

  I'm working on a catalog with a lot of products, and each product has a table for its specifications.

  The catalogue is ready for printing, but now the customer asks me to enlarge certain parts of the text in the table.

  This means that I have to give some cells more space. The cells have different sizes, and that's the problem:

  Is there a way to define the new cell widths and heights as a sort of "master format" so that I can change the tables
  for the design of new without marking of each column and adjusting by hand?

  Unfortunately, the layout is too complex to have tables on a master page, as they are not on a particular coordinate

  throughout the catalog.

  I hope I described my problem quite clearly I'm no native speaker

  I thank very you much in advance!

  Max

  The script linked in the post one of this thread will allow you to adjust automatically to match - table column widths it allows to save the widths of a table in the style of the table and then apply them to other tables of this style.  I don't know about heights, but if all the heights will be the same within a given table, you can select all the lines and enter the exact height of the cell.

• Get the sizes of tables with the same name but from different schemas

  There are two patterns in my database: HAND and ARCH.
  Each of these schemas contains a table named SPOITEMS. I would like to get the size of the table "SPOITEMS" of patterns one and another.
  I found this script:
  
  Select
  nom_segment table_name,
  Sum (bytes) /(1024*1024) table_size_meg
  Of
  user_extents
  where
  segment_type = 'TABLE '.
  and
  nom_segment = "SPOITEMS".
  Table_name group
  
  but it returns only a single element with the name of the table "SPOITEMS" (owner ARCH).
  
  Any ideas?
  
  Thanks in advance

  I assume that you run the query in the ARK? Use ALL_EXTENTS or DBA_EXTENTS instead of USER_EXTENTS

• Limit the size of tables in excel

  Hi everyone, I'm trying to export a table to excel and I am having trouble.

  First of all, I used 'Write to worksheet File.vi' to create a file .xls and has perfectly worked, but now I need to export a table to another sheet of the same xls file (whose name we should be able to choose), so I started to use ActiveX controls.

  I can create the new worksheet with the desired name and write the data into it, but the problem is that it does not show my table only, but also ALL the cells (65536 x VI) with the value # n/a.

  I can solve the problem in one of the dimensions, but not in both entities. This is the first time I use the ActiveX functions (I built this VI with the help of other examples I found in the forum), so I think I'm missing something important.

  What can I do to not show THAT my table?

  Thank you very much for your time and knowledge.

  In addition, you close twice the _Workbook reference, thus generating an error. Here's how to do it. The neck line to Format.vi beach is drawn from here.

• Dynamically set the size of table

  Hello world!

  I have a table of cluster (each cluster contains 4 values) and according to the interactions between users, new groups are added to the table. I would like to set up a 'Clear' button which removes all elements inside the table, but I can't find a solution so far. The best I can do is put all the elements of the cluster to 0 but the cluster itself is always in the table.

  Does anyone know how to do?

  Thank you very much

  Julien

  Hi jfcors,

  the cluster must be in the table, because it defines the type of data in the table.

  You also seem poorly understand the term "empty array": a table is empty when there is no elements inside!

  Extracted from:

  

  @aCe:

  Your example only removes an element of an array, but not the entire table! Sorry, it's okay...

• Given the reference to an order, how can I get size of table programmatically

  If a reference to a command is passed to a sub - vi, how to get the current length of the array in the sub - vi?  I tried two properties: "NumRows", such as documented, with the visible number of rows in the table control.  'IndexVals' contains the index of the array element in the upper left corner of the table control.  There seems to be no method to obtain the length of the current array.  I tried to change the class of the reference to a matrix to regroup before using the property of '[] 'checks... but this has generated a runtime error.  What Miss me?  Thank you.
