size of table in query

• 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.

  '2' in your question means "to"? If so please do not use text instant message in this forum.

  Now I suppose that PRE_RATING_LEVELS is a table in your application. And you are trying to include this table in an existing query. But in doing so, you have found the Cartesian product, correct?

  In fact, how do you think someone a public forum without any knowledge of your table and data structure could help you?

  Lets see, here's your query. I formatted.

      by papf.employee_number 
  

  Now, you want to add the PRE_RATING_LEVELS in the list so that you can use the column NAME.

  First thing you need to do is to determine the relationship between PRE_RATING_LEVELS and other tables. A relationship can be

  1. one on one
  2 one-to-many
  3. - to-several

  So when you tried to join, your state of health has resulted in 2nd or 3rd type of relationship. If you arrive with someone who knows the business and the data and find the table that could uniquely identify a line of PRE_RATING_LEVELS.

• Refresh table-form query on table only for pages in .jsff

  I have a group being generated as a presentation of table form. I would like for the page of the table to always refresh, and submit the form to refresh page after.
  I saw a thread about how to do this on a .jspx page: Refresh table-form query on table only
  
  Unfortunately, this does not work for me because I use the .jsff pages and they do not have access to the facesContext. Does anyone know how to do this for a .jsff page?
  
  Thank you
  Michelle

  Michelle,

  The taskflow 11 ADF in the equivalent of the region of this expression would be

  #{jhsPageChanged and controllerContext.currentViewPort.viewId=='/MyGroupTaskFlow/MyGroupTable'}

  Unfortunately, this currently does not work because there is an error in the JhsNavigationHandlerImpl class we're going to fix in the next release.
  You can apply a work around by creating a subclass of JhsNavigationHandler and replace as follows:

  ' public Sub handleNavigation (FacesContext facesContext, string action,
  The string result)
  {
  String oldPageFragmentId = ControllerContext.getInstance () .getCurrentViewPort () .getViewId ();
  super.handleNavigation (facesContext, action, result);
  String newPageFragmentId = ControllerContext.getInstance () .getCurrentViewPort () .getViewId ();
  If (! oldPageFragmentId.equals (newPageFragmentId))
  {
  JsfUtils.storeOnRequest (JHS_PAGE_CHANGED, Boolean.TRUE);
  }
  }

  To use your subclass, create a custom template for the facesConfig.vm and modify the navigation Manager to use your subclass.

• Table sizing Query Help

  Hi all

  I'm working on a query to the tables of dimensions. I want to be able to retrieve the total number of bytes and unused bytes for tables and their indexes. I also want to be able to combine all the output in several long strings to paste into simple rows of an Excel for analysis later. I could get that day:

  DECLARE

I have SQL Server I would be cheating by using sp_MSforeachtable, that would allow me to keep the results of the stored procedure as a relationship.

  Thanks for any ideas or suggestions.

  So I thought about my own questions by using the following query instead of the stored procedure...

  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.
