• Clear on how the table of Index OpenG works with a 2D Arrray

  Hello

  I don't understand how to use the undex OpenG table with a table entry 2D. I joined the contest help window, said that aid

  "For 2D tables, connect the clues and indices 0 1 entries to specify the items you want.

  So what does really mean? I wired the vi as requested and the vi always puts a 1 d table. So are the lines of entries in table two indexes and columns or what?

  I am sure that you send in your line indices table and the table of the column indices and get out of your table 1 d of elements.

  (i.e. rank table [1,5,7] and table column [4,8,10] gives you a table 1 d elements (1,4), (5.8), (7.10))

• How FLASHBACK all TABLEs and indexes in a certain pattern for a restoration of p?

  Today I read a few web pages on how to use FLASHBACK to restore to a Restore Point.
  
  Unfortunately, all of these examples show just how to restore a single TABLE for example
  
  FLASHBACK TABLE t to RESTORE POINT before_we_do_anything;
  
  But how can I FLASHBACK all TABLEs (and indexes and other dependent objects) in a certain pattern to a one-step restore point)?
  
  FLASHBACK myschema.* to before_we_do_anything POINT of RESTORATION;
  
  does not work.

  There is nothing like that. However, you could flashback the entire database to a point in time. It would of course have implications through patterns all the good.

• 10.1.3: how the client ID of the elements in a specified af:table?

  Hi all
  
  I have an af:table (let's say the departments) with some columns (say DeptName) is one of them and (say) a range of 15 ranks. Normally, modulo naming containers, the clientId of the field DeptName is of the form:
  
  Departments: 0_indexed_row_in_af_table:DeptName
  
  So, for example, DeptName field in the third row of the table will be
  
  Departments: 2:DeptName
  
  The problem occurs when, due to, say, a data change and refresh, a partially separate set of lines appears in the table when updating. Then, all the old lines reappear will keep their old , but News clientIds lines will get new numbers, from 15. So, if the update the first and third rows in the first and fourth, retains, and retrieves new lines for the second and third position the client ID for the first fields in four departments such as they appear in the table will be:
  
  
  Departments: 0:DeptName
  
  Departments: 15:DeptName
  
  Departments: 16:DeptName
  
  Departments: 2:DeptName
  
  If new data completely , the table will be rendered starting with departments: 15:DeptName.
  
  My question: is there a way to understand, by program, what the customer for a particular area of DeptName ID will be, assuming that the table could have been refreshed with partially or completely new data in an arbitrary number of times?
  
  Thanks much for any help.

  Hello

  Try something like the following:

  RichTable table = // Get the table component instance somehow;
  int rowIndex = // Find the right row and get its INDEX in the ResultSet and/or data, not the row key
  
  // Save row state
  Object oldRowKey = table.getRowKey();
  try
  {
      table.setRowIndex(index);
      UIComponent field = table.getChildren().get(columnIndex).getChildren().get(0); // Get the field from column columnIndex
      field.getClientId(FacesContext.getCurrentInstance()); // Since setRowIndex was called, the id should be correct
  }
  finally
  {
      // Restore state
      table.setRowKey(oldRowKey);
  }
  

  The idea of rowKey vs rowIndex is rowKey is stable to ensure that a key to the given line is always the same line (very useful to avoid a strange problem with sorting), while the line index change with the position of the line.

  Kind regards

• Write only the range specified 2D table data to a string worksheet?

  Hi all

  My problem today is a simple, but for the life of me, I can't find an answer using search. I have a table of 2D data points (values of Y) with their corresponding index numbers. When I start my VI, I retrieve a table of 10's of thousands of values, but I want to be able to extract only a few hundred values (specifically, one or two periods of a periodic sound of the waves) at the most to display in a string of spreadsheet for further calculations in Excel.

  I managed to get the data written to the string of spreadsheet easily, but I'm stumped on how to specify the range (using the index values) to allow to write in the worksheet line. I tried "delete table", but I must be missing some functionality, because I can't seem to remove all values above one index max and min specified index below (in order to simply get the values between max and min).

  Help a beginner?

  Appreciated.

  I am using Oracle 11 g R2 (11.2.0.1.0) for Microsoft Windows (x 64), running on Windows 7.

  An extension to what Sybrand said:

  There is a parameter called differed_segment_creation, who runs the behavior.

  If it is set to TRUE (the default), no segments will be allocated until you fill your table / index.

  Try to insert a row. You will see your table and index in dba_segments.

• Partitioned Tables and indexes

  Hello
  
  
  I have a question on the table and index partitioning. My scenario is:
  
  Charge 2 mio records in table T once a month. Loaded records are added to existing records, and once loaded data is never changed.
  At some point, I want to delete the older recordings, so I intend to this partition table.
  
  T table looks like:
  

  create table t (id       number(10) not null  constraint t_pk primary key,
                  period   number(10) not null,
                  contract number(10) not null,
                  attr     number(10) not null);
  
  create unique index t_ux1 on t(contract,period);
  
  create index t_ix2 on t(period);

  My plan is to partition T over the period, and I'm trying to read through the concepts
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14220/partconc.htm#g471747
  
  
  My question is now, how to manage the indexes, the t_pk, the t_ux1 and the t_ix2. Concepts of say,
  
  «1. If the table partitioning column is a subset of index keys, use a local index.»
  
  "2. If the index is unique, use a global index. If this is the case, you are finished. »
  
  
  So, that's how I read it
  -t_pk is unique, so this should be global
  -t_ux1 of columns is a subset, unless I have misunderstood (?), which should be local
  -index t_ix2 column is the same as the partitioning column, so it must be local
  
  Is this right, this t_ux1 should be a local partioned index, even if the period is the second column in the index?
  
  If true, what will happen when a partion fell?
  
  
  I am new in this area, so please feel the comment as you wish.

  Is this right, this t_ux1 should be a local partioned index, even if the period is the second column in the index?

  A partitioned index locally can only be defined as unique if the partition key is part of the columns in the index. Imagine what the database would have to do if this is not the case: in order to verify if a newly added or updated value violates the uniqueness, it will have to travel all the partitions in a serialized operation - means that no one else could do the same thing at the same time. Since he is a killer of serious scalability in terms of locking and contention, this is not allowed.

  So: Your T_UX1 index can be defined as a unique index that is local because it contains the partition key. Although the index is not prefixed ("Prefix" means that it is divided by the left side of the columns in the index) which means that there may be access patterns where all partitions should be scanned or the optimizer cannot use a method of size of effective partition according to the way the index is reached.

  Your T_PK index cannot be set as local because it must be unique (you can not use a local non-unique index in this case), but does not contain your partition key. It must be a global index. An overall index can be partitioned as well (different from the underlying table) but it doesn't have to be.

  Depends on how you access your data you have not T_IX2 index when partitioning by this key because it corresponds to the partition key and therefore could not actually be used by the mechanism of partition pruning that limit your query to the scores of individuals.

  If you have more than one MAS environment where running queries are used longer, you should be fine with the index the in general (because they could be analyzed in parallel in parallel operations), but if you have an OLTP environment, then you should avoid local no prefix indexes due to the potential problem that you need to analyze all partitions.

  Be borne in mind that with partitioning adds an important layer of complexity to other areas: in particular the options available to the optimizer and analyze cost optimizer statistics. Depends on how you access your statistical data must be maintained on several levels now (level of score and at the global level, in the case of subpartitioning may be still at this level). If your data is important and you rely on "global" level statistics (these are always the case when the optimizer at the time analysis cannot limit access to a single partition) then in the pre - 11 g databases analyze these "global" level statistics can take a lot of time and resources, since actually , you need data several times (once for the partition and even global level).

  Presenting this partitioning may mean other potential problems in terms of execution that change (not for the better sometimes) plans and how to effectively collect statistics. Note that g 11 addresses the issue of 'statistics' by introducing the so-called "extra" global statistics. Greg Rahn wrote a [blog note | http://structureddata.org/2008/07/16/oracle-11g-incremental-global-statistics-on-partitioned-tables/] on this nice feature.

  >

  If true, what will happen when a partion fell?

  Since you're already on 10g, you can specify the database to update the scores of the local index using the UPDATE of the INDEX clause, while 9i could maintain only an overall index and it is up to you to rebuild the local index partitions after the partition DDL on the table (according to the DDL operation).

• How to build a table of TDMS file open

  Hello

  Examples NI TDMS - Express write data .vi (time domain), I can build a PDM file with 2 channels (sine and square waveforms) data, which are stored as test.tdms.

  Using Express read .vi data (time domain), 2 channels of waveform data are read. How to build a table later? How to separate the 2 channels of data in the tables 1-2 and manipulate the data using table functions?

  For example,.

  I want to collect 100 from index100 between channel 0 and their average. I want to take 50 samples from the channel 50 1 index and double each element.

  Thank you for your help.

  Bing@NCL

  Hey Bing.

  You can perform operations on different channels in the 2D table using the table to index. This will allow you to choose the channel to operate on, then you can perform the operation inside a loop on each element. In the included code snippet, I used a shift register to find the total cumulative values in channel 0 and then divided by the number of samples.

  I recommend you read some tutorials LabVIEW and bases of knowledge on topics that are related to yours. These could help a lot.

  I hope that my suggestions help,

• How to create a table in if/else or structure without 0-case?

  Hello

  I tried to do for a while now.

  I only managed to think about this in three ways:

  1. (what I'm doing right now create the table through a loop for, fills the table in automatic indexing.) Filled it with many of if true and with a '0' if the value false. The idea was to remove the 0 later in the code. However, this seems very inefficient.

  2 make use of a registry change, which automatically adds the correct number of a table. The problem is that the table will keep growing and growing and at the very least would enormously slow down my program. At worst, it would break.

  So my question is: how to create a table that if a comparison is true, it puts the item in and if not, it does nothing?

  I have attached a PNG of my code snippet.

  Kind regards

  David.

  If you want to only affect exactly as much memory as you need for the table, you can count the number of true elements in the table of Boolean everything first and then assign one of exactly this size. In this way, you are more memory and time-efficient whether overuse (such as allocation of an array of I32 as big as the whole table boolean) or underallocating (from zero element and let it grow automatically whenever you add on).

  Count the true values, allocate an array only the great and then replace each value in this new table with indexes / "I ' value where the real exists." An excerpt from VI:
