Index of the raised event boolean table

Hello fine people of the interwebs.

I'm in a bit of a pickle. I have an image analysis triggered Boolean that returns under a measure. I want to store the result whenever the process is triggered in a table, up to 6 items. The process would crush the steps in order, until another process is triggered to write the data to storage and clear the table. I downloaded an approximate example of what I'm trying to make (less data storage routine). Any help would be greatly appreciated

Looks like you're going to get something like that...

How it warns Oracle to use an index for the join of two tables...
How to prevent the Oracle to use an index for the join of two tables to get a view online that is used in an update statement?

O.K. I think I should explain what I mean:

When you join two tables that have many entries sometimes there're better is not to use an index on the column that is used as a criterion to join.

I have two tables: table A and table B.

Table A has 4,000,000 entries and table B has 700,000 entries.

I have a join of two tables with a numeric column as join criteria.

There is an index on this column in A table.

So I instead of
```
  where (A.col = B.col)
```
I want to use
```
  where (A.col+0 = B.col)
```
in order to avoid Oracle using the index.

When I use the join in a select query, it works.

But when I use the join as inline in an update statement I get the error ORA-01779.

When I remove the '+ 0' the update statement works. (The column is unique in table B).

Any ideas why this happens?

Thank you very much in advance for any help.

get the index of the same values in table

Hi guys,.
I'm trying to get the index of array elements with the same value but it can solve mine.
my case is:

array1 = [1,2,3,4]; <-here are the names of the pages, always in the order of CSA (these table I used only to check the results of my work, probably will not be for you but maybe...)
array2 = [1,1,2,2,2,3,4,4,4]; <-these numbers are random, but always in the CSA order (these are the names of pages for items in table 3)
array3 = [a, b, g, i, f, e, c, h, d]; <-these are all the values of the elements I want to work with later. number of articles is still the same as in array2, their indexes are corresponding.
array4 = [];
I need to remove array3 everything, but one of each issue of array2 (as I will remove duplicates) or push to array4 an article of array3 for each number of the array array2 (as I'm going to ignore duplicates)
don't know is my desc is clear enough, but the result I get is:
ex. [a, g, e, c]
above example for each number of array2 array3 items, but do not have to be first, can be second or third if etc exist, but have to be alone.
I thought that if I get duplicate values, the index in the array array2 and delete this index in array3 will get what I want, but can not solve.
You will appreciate all help.
Thank you

Try something like this:
```
var array2 = [1,1,2,2,2,3,4,4,4];
var array3 = ["a","b","g","i","f","e","c","h","d"];

var tempArray = [];
var resultArray = [];
var n , x ;

for(var n=array2.length-1;n>=0;n--)
{
    var string = ""+array2[n];
    tempArray[string] = array3[n];
}

for(x in tempArray)
{
    resultArray.push(tempArray[x]);
}

resultArray.reverse();
// a,g,e,c
```
Hope, that helps.

Parent index for the data in a table?

Is there a way to index a child table with a function to include a column from a parent table?
Example:
I want to see how many children live in a zip code (and their address is listed with their parents)
Select count (*)
class c of child, parent p
where c.parent_id = p.parent_id
and p.zipcode = "12345"
Is there a way to make an index of children with a function that gets parents zip code?
Thanks for the help?

An index on the child table can reference only the columns of the child table. You can't have an index on the child table that is based on information from the parent table.

There are the function-based index, but they may involve only constants and deterministic functions (and, of course, the columns of the table). For example, the child table could have a clue on UPPER (name), where last_name is a column of the table, but he could not have a clue about get_zip (parent_id), where get_zip is a function defined by the user who queries the parent table.

Well - you "might" have a functional indication if you did to be deterministic, but it is not recommended because if the changed zip_code parent would really not deterministic and the change would not be included in the index.

This apart from this code will work properly if the zip_code data does not change:

CREATE TABLE parent (COL1 number primary key, zip VARCHAR2 (5))

create the child table (col1 number, parent_key number);

create or replace function get_zip (number p_key) return deterministic varchar2 as
v_zip varchar2 (5);
Start
Select zip from v_zip of the parent where col1 = p_key;
Return v_zip;
end;

/

create indexes on children (get_zip (parent_key)) child_zip;

Boolean index in the array

In Matlab, often use a Boolean array to access the specific values in a table.

It is a good way to reduce the itterative loops and improve the speed of the code.

I'm trying to find a way to do this in a Mathscript node, otherwise the code takes forever to run.

Common code in Matlab and Mathscript:

a = [1,2,3,4,5]; % This is normally a much larger range

b = [1,0,1,0,1]; %I whether Boolean, but by default it's double

c = b > 0; b change % to boolean

d = [9,9,9,9,9];

The Matlab code is:

d (c) = a (c);

d

> d = [1 9 3 9 5]

If I run the above in Mathscript, I get the following error:

In Mathscript, to achieve the same result "d" I currently have this:

for i = 1:length (d)

If c (i) == 1

d (i) = a (i);

end

end

d

> d = [1 9 3 9 5]

A slightly faster version is:

for i = 1:length (d)

j = 1;

If c (i) == 1

e (j) = c (i);

j = j + 1;

end

end

d (e) = (e);

d

> d = [1 9 3 9 5]

Any ideas?

Thank you

Hello

The code you have posted works fine in the MathScript in LabVIEW 2009 node as well as in the MathScript window and the MathScript node in LabVIEW 8.6. As such, I'll assume that you have found an error in the window of MathScript in LabVIEW 2009. We have already identified this problem and currently filed the bug report 151999 for her. You see error message did not come through in your post, so I guess it is-90026: ' indexes for an indexing operation matrix must be real and positive integers. " The problem is that we do not treat the indexing variable 'c' as a boolean type. As a result, it reports an error when it tries to use the index 0 instead of a fake. We are working on a fix for a future version.

To work around the problem in the MathScript window, you can use find instead of any Boolean indexing command. It should integrate more quickly than the implementation of loop that reference you. Instead of
d (c) = AC;
use
d (Find (c)) = a (find (c));

Convert the Boolean table 1 d in Boolean

How to convert the Boolean table 1 d to Boolean? Actually, I take a digital input of sensor using data acquisition (NI USB 6009) and I give this digital input to a structure of case to change a condition, but the source type is table 1 d & sink is boolean(TRUE/FALSE).i have attached vi of the above condition, i only replaced Boolean table rather than real acquisition of input data.

Thanks for your suggestion, I couldn't open your vi cuz I use the 2009 version of labview, but I found the solution to this problem, we can use the table to index. I have attached the vi.

How can I connect 2D Boolean table at the entrance to the structure of the case?

Hello

I would like to know how to solve this problem. I try to connect the output of a digital 2D painting and a constant number of 'BIG' before you connect it to the entrance of the structure of the case. An error message appears and it shows ' the type of the source is a 2D boolean array. The sink type is Boolean "."

I tried to 'disable indexing' on the box of the structure of the case, but the error remains. Would appreciate any comments on it.

How to create indexes on the ordered collection of XMLTYPE table?

I use Oracle 11.2.0.2.

Basically, my XML documents have a 3-level hierarchy:

event

+ - action [1: n]

+ - param [1: n]

I try to create indexes on the tables of the orderly collection, but cannot get the right syntax...

I created a table with an XMLType object-relational column:

CREATE TABLE T_C_RMP_MNTRNG_XML_FULL_IL4 (
  MESSAGE_ID NUMBER(22,0) NOT NULL ENABLE,
  XML_EVAL_ID NUMBER(22,0),
  VIN7 VARCHAR2(7 BYTE),

  NOLOGGING TABLESPACE "CATALOG"
  ) RETURN AS LOCATOR
) RETURN AS LOCATOR
XMLTYPE XML_CONTENT STORE AS OBJECT RELATIONAL XMLSCHEMA "http://mydomain.com/cs.xsd" ELEMENT "monitoring";

I execute the SELECT statement:

SELECT EVENT_ID, ACTION_SUB_ID, MESSAGE_ID, ACTION_TYPE, UNIXTS_TO_DATE(ACTION_TIMESTAMP) ACTION_TIMESTAMP
FROM T_C_RMP_MNTRNG_XML_FULL_IL4, 
XMLTABLE( 
  'for $i1 in /monitoring , 
  $i2 in $i1/action            
  return element r {              
  $i1/eventId,              
  $i2            
  }' 
  PASSING XML_CONTENT COLUMNS 
  EVENT_ID VARCHAR(40) PATH 'eventId', 
  ACTION_SUB_ID INTEGER PATH 'action/actionSubId', 
  ACTION_TYPE VARCHAR2(100) PATH 'action/type', 
  ACTION_TIMESTAMP NUMBER(13,0) PATH 'action/time'

WHERE (

)

How can I create an index on these tables of the ordered collection to improve performance?

I found the example at http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb_rewrite.htm#ADXDB5859 but am not able to apply to this particular case...

Thank you in advance...

If the schema is not annotated and XS: Integer and XS: String are mapped to types of data NUMBER and VARCHAR2 (4000), so you must use in your query to avoid typecasting unnecessary operations.

You must also use XMLTABLEs chained when accessing a parent/child instead of a FLWOR expression relationship, otherwise the CBO cannot rewrite the XQuery query correctly (maybe it's fixed in the latest version).

If you make these changes, the plan should show the cleaner predicates:

SQL > SELECT EVENT_ID, MESSAGE_ID, ACTION_TYPE, ACTION_SUB_ID, ACTION_TIMESTAMP

2 FROM test_table

3 XMLTABLE ('/ monitoring ')

4 COLUMNS XML_CONTENT OF PASSAGE

5 WAY of VARCHAR2 (4000) EVENT_ID "ID."

6 actions for XMLTYPE PATH 'action '.

(7) T1,

8 XMLTABLE ('/ action')

Shares of PASSAGE 9 COLUMNS

NUMBER of ACTION_SUB_ID 10 PATH "actionSubId."

11 PATH of VARCHAR2 (4000) ACTION_TYPE "type."

12 WAY of NUMBER ACTION_TIMESTAMP 'time '.

(13) T2

14 WHERE EVENT_ID IS NOT NULL

15 AND ACTION_SUB_ID IS NOT NULL

sorting table, how to get the new index of the last value?

Hi all!

I use a Subvi, which adds a cluter of the parameters to an array and then sort this table by one of the parameters in clusters.

It works very well, with examples, that I found in this forum

but now, I would like to know if it is possible to obtain at the end of the new cluster index first added.

See attached VI

Thank you

You take the size of the table and insert the new element to this level is anything other than the table of construction and a simple construction would do that.

In your question, I assume you're asking on the index of the item that you inserted after the sorting of the table, right? In this case, you can compare the cluster element that you introduce to the initial with the cluster table you get after a sorting of the table. This will give you the index of the item that you insert at the start.

Search index of the secuence valuation until you reach a constant value table...

Hello

I have an arry of secuence RR values (its peak at the time of peak of ECG wave is seconds). I know that the added value of the paintings is the total time of sample data.

I would like to separate in different charts in the representation of every hour of recorded data.

I need to get a way to get the index where the number of added values are-online 3600 s (1 h).

So that I can know the index of the arrays values to get the correct index in chart 1 h values, another index for another hour for an another graph,... so until you get the hourly chart several data can show.

I hope you understand me.

Best regards.

Modulo division is performed by the function Quotient & remains on the digital palette.

Work with tables and data DBL or integer types.

When I use the method that Mike designed, in my view, the VI sometimes lacks a time transition. This happens with the simulated data that I generate because it is possible that the rest is different from zero. For example, this can happen if the accumulated sum is 3599.4 s and the next RR interval is 1.3 s. Which gives the following sum = 3600.7 s. The conversion by multiples of the amounts of 3599 and 3601. The remains are 3599 and 1 after modulo division. None are exactly equal to zero.

I've changed this option to use DBL and then look the big negative transition. The minimum value may be with the largest range of RR in the data. However, there is always a great transition close to 3600 to near zero.

'For' loop with a different number of iterations. Second, the auto-indexation of the tables with different sizes is done. It can affect the performance of the Vi?

Hello

I have a loop 'for' which can take different number of iterations according to the number of measures that the user wants to do.

Inside this loop, I'm auto-indexation four different 1 d arrays. This means that the size of the tables will be different in the different phases of the execution of the program (the size will equal the number of measures).

My question is: the auto-indexation of the tables with different sizes will affect the performance of the program? I think it slows down my Vi...

Thank you very much.

My first thought is that the compiler to the LabVIEW actually removes the Matlab node because the outputs are not used. Once you son upward, LabVIEW must then call Matlab and wait for it to run. I know from experience, the call of Matlab to run the script is SLOW. I also recommend to do the math in native LabVIEW.

Get the index of the column of table removed

Is there a way to get the index of the column in a 2D table that has been deleted? In my application, the user has the possibility to use the right click option 'remove a column' on a 2D picture, but I would like to use this information to remove the same column in a different table programmatically. Is this possible?

There is a file published in the documents of the community that refers to a location in a sheet of the user has clicked. Use it like the image below.

Creating indexes for the table

can someone help me how to create indexes in the table. I m creating own table... I need to select a particular field in the table. So I need to calculate the index position. I use my code like this,

This will returnthe number of columns in the table.

Class array

{

private int Table_Index()
{
for (int x = 0; x)<>
{
table_index = x;
}
Return table_index;
}

}

MainClass can I get this length of Index

Table T1;

int t1 is T1. Table_Index();

This property returns my length (4) of table column

Using this index (t1) I HAV to see what position I'm at table now...

someone help me...

You can use a listfield, he supports methods to get the selected row and its contents.

Why I can't create indexes on the table of RDF data

When I tried to create indexes on the table of RDF data, it always say the table or view does not exist. I created the RDF model using java codes:
Oracle Oracle = new Oracle ("jdbc:oracle:thin:@localhost:1521:orcl", "system", "123");
Chart GraphOracleSem = new GraphOracleSem (oracle, "test2");

And used the following commands in sqlplus to create indexes:
SQL >
SELECT THE SEPARATE OWNER, OBJECT_NAME
FROM DBA_OBJECTS
WHERE TYPE_OBJET = 'TABLE '.
4. AND OBJECT_NAME like ' % TEST2;
OWNER
--------------------------------------------------------------------------------
OBJECT_NAME
--------------------------------------------------------------------------------
SYSTEM
TEST2_NS
SYSTEM
RDFB_TEST2
SYSTEM
TEST2_TPL
OWNER
--------------------------------------------------------------------------------
OBJECT_NAME
--------------------------------------------------------------------------------
SYSTEM
RDFC_TEST2

SQL > connect as sysdba
Enter the password:
Connected.
SQL >
SQL >
SQL > select * from TEST2_TPL;
Select * from TEST2_TPL
*
ERROR on line 1:
ORA-00942: table or view does not exist
SQL > CREATE INDEX test2_sub_idx ON TEST2_TPL (triple. GET_SUBJECT());
CREATE INDEX test2_sub_idx ON TEST2_TPL (triple. GET_SUBJECT())
*
ERROR on line 1:
ORA-00942: table or view does not exist

Hi Shifu,

It is not recommended to use the SYS or SYSTEM to store/manage schema graph RDF data.

Can you please try the following in a SQL * more terminal?

SQL > conn system/eu1

Connected.

SQL >

SQL >

SQL > create user graphuser identified by graphuser;

Created by the user.

SQL > grant connect, resources, unlimited tablespace to graphuser;

Grant succeeded.

SQL > conn graphuser/graphuser

Connected.

SQL > create table graph_tpl (triple sdo_rdf_triple_s) compress;

Table created.

SQL > sem_apis.create_sem_model exec ('graphic', 'graph_tpl', 'three');

PL/SQL procedure successfully completed.

SQL > insert into graph_tpl values (sdo_rdf_triple_s ('graph', '', '', ''));

1 line of creation.

SQL > select count (1) in the mdsys.rdfm_graph;

1

You see the same result?

Thank you
