Indexing table 2D

So I have a problem getting this table 2D simple vi to work the way I think it should. The vi is drawn from a larger that I am writing to provide movement control signals at a stage of position engine 3 stepper motor axes. In vi, the data written to the array element in the loop is detected among the stepper motors position value.

How does this vi is just out of the loop, only the final element in the 0 row has been updated, as opposed to each element of line zero, which is what I'm after.

What I am doing wrong?

The Ahh right. I just went and changed my full order of engine vi with SHIFT registers and verified that this is the way to go. Thanks for sorting that one out. I honestly would not have thought it was the change needed.

Performance when indexing table 1 d of table 2D

In the attached extract, I'm trying to store images from a camera in a pre-initialise table. The GetImages16 function is a wrapper of commercial for a DLL that takes a pointer to a 1 d array and writes the image of the camera. My Images in table must store 1500 ~ frames of images of 128 x 128 pixels, so I assigned a 2D of 16384 x 1500 table.

The problem I have is that table indexing Images significantly slows down that I increase the number of images, and I can't keep up with my camera. Three things correct this code:

1. reduction of the size of the Images of 1500 images to<400 frames="" or="">

2 image making a 1 d array and passing it directly.

3. moving code from indexing outside of the loop.

So, even if the location of the first image of Images should not change, it seems to take significantly longer (~ 5 ms) to perform indexing of Images when the pre-initialise table becomes large (> 400 frames). This suggests that I couldn't be very good memory management, but I'm a noice from LabVIEW relative in this area. I tried indexing column instead of line and get the same performance.

Suggestions?

Maybe I simply don't see, or maybe that is not visible in this picture, but I don't see anywhere that write you to the local variable of the "Perle of Images", so I don't see how it's helping you. Again, it would be useful to see the subVIs. Can you post a ZIP file containing all your screws, instead of just images?

To share a great picture between the loops, the best option is an action VI engine that stores the chart in an uninitialized shift register. At a minimum, it must have actions to initialize the table records an image in the table and retrieve an image. There also other treatment options, so you can operate directly on the data in the table.

Replacement after the specified index table

Hello

I am completely new to labVIEW as a student. I have a question to overwrite a table once received at a specified index.
In particular, I have to add up numbers in a table at all times and take the average of the last three values.

I wanted to make a new table that stores the three numbers and after that, began to replace the first, then the second, the third, first of all, the second you...

Can someone help me, showing me how to cut my tables up to a limit of 3 values?

Thanks in advance!

(Sorry for the bad English)

To take the average, the order of the array is unimportant. Here's what I'd do.

(With a little more code, it also works for the first couple of iterations.) See this old post)

There's also means ptbypt, which does the same thing!

Path to XML index table is full table scan

Hi all
I have a version of oracle 11.2.0.4.6 database
Try to implement partitioning on XML indexes.
Creates a table and index partitioned by time stamp as below.
Whenever I'm trying to find the path table makes a full table scan.
I have applied the fix as indicated ( Doc ID 13522189.8 ).
So the recovery is quite slow and partition pruning does not not on XML indexes.
Wondering if anyone has experienced the same problem?

Performance problem when inserting in an indexed table space with JDBC
We have a table named 'feature' that has a "sdo_geometry" column, and we created the spatial index on this column,

CREATE TABLE (ID, desc varchar, sdo_gemotry oshape) feature

CREATE INDEX feature_sp_idx ON feature (oshape) INDEXTYPE IS MDSYS. SPATIAL_INDEX;

Then we executed following SQL to insert some 800 records in this table (we tried this using the DB Viewer and)
our Java application, both of them were using JDBC driver to connect to the database oracle 11 g 2).

insert into feature (id, desc, oshape) values (1001, xxx, xxxxx);
insert into a values (id, desc, oshape) feature (1002, xxx, xxxxx);
...........................
insert into a values (id, desc, oshape) feature (1800, xxx, xxxxx);

We met the same problem as this topic
Performance of the insert with spatial index
It takes almost 1 dry for inserting a record, compared with 50 records inserted per second without spatial index.
which is 50 x slow performance when you perform the insertion with the spatial index.

However, when we copy and paste these scripts inserted in Oracle Client(same test and same table with spatial index), we got a completely different performance results:
more than 50 records inserted in 1 seconds, as fast as the insertion without having to build the spatial index.

Is it because that the Oracle Client not using JDBC? Perhaps JDBC has been something bad when updating of these tables indexed on the space.

JDBC normally use autocommit. So each insert can leads to a commit.
I know not all customer Oracle. In sqlplus, insert is just an insert,
and you run "commit" to commit your changes explicitly.
So maybe that's the reason.

ORA-06502: PL/SQL: digital error or value: the value of key NULL index table?

Hello

Can someone let me know what is the problem the code below and how can we avoid this? I get the error message as below

Change:

WHILE v_while_loop <> v_tabtype_result_values.COUNT

WHILE v_while_loop <= v_tabtype_result_values.LAST

best large association index table
Hello

I have an association table:

SURROGATE_ID, CONTENT_TYPE, OWNER_ID, REF_COUNT

The SURROGATE_ID is an auto-generated primary key.
There are about 5 numbers of different types of content.
There are a large number of long integers OWNER_ID, including a value of NOBODY_ID.
The refcount reflects the number of content for this type with this owner.

I need a quick query COUNT (*) which, for a given value of CONTENT_TYPE and a given value of OWNER_ID, counts the number of lines (zero or one) with REF_COUNT > 0.

My naïve ploy would be orthogonal CONTENT_TYPE, OWNER_ID and REF_COUNT index.

And to build a query reasonable not worry about the order of the conditions:
When CONTENT_TYPE =: mytype and OWNER_ID =: myowner and REF_COUNT > 0

Can someone tell me the wiser index to use?

fast, would be as fast as possible. Always the same query. Orthogonal means an index on each of the 2 columns, that no orthogonal while would mean to me, an index on the columns together. Moreover, maybe I need actually the value for a specific CONTENT_TYPE refcount, pair OWNER_ID: Yes, that's what I need.

Thanks for the explanation.

You want to do that (separate index), and IF you did you would index BITMAP, but I highly doubt that they are appropriate for your case so lets pretend that I never did :)

My suggestion for an index, which would use an analysis complete index, which means that you don't need to visit the table (as I thought he had a lot of other columns in the table) or Solomon would be the direction to head in.

When creating index table lock?
Hello

My db is oracle10g. My database is OLTP system. I wanted to create the index on one of the table. The table has 200 million recordings.

It locks the whole when table I create index? I think, its impact on the regular operations of the database when creating the index?

Any help is appreciated...
Hello

You have Enterprise Edition? If so, the online option is available.

So you can do:
```
create index my_new_index on my_tab(col1,col2) online;
```
or:
```
alter index my_existing_index rebuild online;
```
If you are not using the online option, then Yes, the table will be locked for updates, all traffic OLTP will serialize buttocks the index maintenance operation.

Hope that helps,

However, the longer name of my models is 23 characters, making it the longest name of characters 27A table (+ _TPL).
Is there a still shorter limit for the length of model name?

Thank you

Kind regards
Julien
Hi Julien,

In fact, the limit for a semantic model, created using the Jena adaptor is 19 characters. This is because the application table index uses TRIPLEIDX as a suffix.

Best,
Vlad

Start to monitor a whild using Index table?
Thank you for taking my question!

I have a very long running job and I first followed the clues he uses. Each index that I try to follow Gets a RESOURCE BUSY error when I try to change the index.

Can someone tell me - is - this means that the index is in use OR you can not change the index when the table is in use?

Thank you!
Kathie
You will need an exclusive lock on the table (or clue?-in this case, it's the same for me) to do ALTER INDEX MYINDEX CONTROL USE

This means that you can not enable monitoring as long as there are other sessions/transactions performing DML against the table.

Index + table pushes indefinetly although many lines remain constant

Indices during the insertion of the keys that are outside their borders previous to continue its growth. They free their "slots" only to reuse them, but never really free unless that forced. To analyze that I wrote a simple test script that emulates a typical scenario of sequence. What strikes me is the fact that table is also growing much more slowly than the index but still.

drop table t purge;

create table t ( n varchar2(4000) );
create index i on t(n);

set serveroutput on;

declare 
  n_numb number(20) := 100000;
  n_isize number;
  n_tsize number;
  n_count number;
begin 
  while n_numb < 350000 loop
    n_numb := n_numb + 1;
    insert into t values (rpad(n_numb,100,0));
    delete from t where n = rpad(n_numb-10000,100,0);
    if mod(n_numb,10000) = 0 then
      select bytes/ 1024 into n_tsize from user_segments where segment_name = 'T';
      select bytes/ 1024 into n_isize from user_segments where segment_name = 'I';
      select count(*) into n_count from t;
      dbms_output.put_line(n_numb||'# '||n_count||'rows table: '||n_tsize||'kb index: '||n_isize||'kb');
    end if;
  end loop;  
end;
/

output:

 drop table t succeeded.
create table succeeded.

Register shift when indexing tables in formula node

Hello

I cannot using the node form while my two paintings of indexing. I'm getting "NaN" for my output array. I think that the problem lies in my shift register. My guess is that for the first calculation is not a PreviousAngle is why it gives me "NaN." The first clue, I would like to than the value of PreviousAngle to 0. I'm new to LabView and know what to do.

Thank you!

A 0 to the N terminal wiring makes no sense. A for loop will iterate for the smallest N or the size of the array. Don't wire anything to N.

How do I loop stops then automatically indexed table is connected to the index of the loop = 0

I connected an array of 5 elements of a loop FOR with indexed auto activated (FOR the index of the loop is not no conthe second), IE after iteration 5 0-4 loop ends automatically ... HOW he gets himself finished?

Index table with scroll

I'm new to Indesign; but I'm looking to do the following:
I want to create a PDF file that has a table on the side left, that would be a clue with scrolling of the subjects for the PDF file. Is this possible in InDesign? And if so, how to create scrollable table?

Oh, it's certainly doable in PDF files. They can not the Language Javascript and do anything.

I don't think it's a good idea, however. Bookmark PDF interface provides the structure and a comfortable interface. If in doubt, invent your own user interface is almost always a bad idea... you will miss something subtle and annoys users and will not have the nice integration with the operating system, browser, or in this case, PDF Viewer, who they know.

It seems that you can do with bookmarks, so you should, in my opinion.

In addition, there are not exactly rich tools to develop the JavaScript in a PDF file. certainly InDesign isn't such a tool (so our Advisor in this forum is of limited use), and I'm not really sure Acrobat Pro is either.

How to get the name of the particular index table option.

Hello
Can any body tell how to get the name of the item to a particular array.i have a table within array.i must compare the name of Francesca in particular key.here is the table.
myArray= Array (@43b1e09)
[0] = object (@42b33f9)
Testing_1 = Array (@4428821)
[0] = object (@43adc19)
choice_id = '0 '.
delete = "N".
DownloadURL = "xyz".
selected = 'Y '.
translation = "2_486."
length = 1
length = "N".
Editable = 'Y '.
field_id = '388 '.
LanguageLink = 'Y '.
linked_definition_id = null
multiple values = "N".
name = "Photo".
otheroption = "N".
photovitlink = object (@43ad0d9)
required = "N".
step = '1 '.
translation = "Photo".
visible = 'Y '.
[1] = object (@43ad5d9)
[2] = object (@4490089)
Here is the structure of the table I get server side.i give table name of result as table myArray.This have several child as an object of object.each having .i table (Testing_1 in the first case) must get the name of this Testing_1 table and compare with my sort key that I perform an operation. But I am unable to get the name of this Testing_1 array(Since_it_is_dynamic_so_this_name_changes_some_times).can a body guide me how to get the name of this table.

Thanks and greetings
Vineet Sharma

Hi Vineet Osho,

You can browse your object using the loop and you can get the name of the table... as below...

for each (var obj:Object in myArray)
{
for (var str:String in obj)
{
If (obj [str] is array)
{
var arrayName:String = str;
}
}
}

Thank you
