How to upgrade a table after each iteration?

Hello

I have a vi which works fine but the problem is that it updates all the data once the vi stops running. I want something as soon as (for outside for loop) 1 iteration it performs updates the table in front of the Panel, then 2nd iteration, it updates again and so on. Can anyone help me please with this.

Thank you

In fact, in your case, there are a simpler way to do it... If we talk about the pink channel on the first loop indicator.

Just move the table from outside the loop inside the loop indicator.

How insert elements into a table after each iteration of a for loop

I'm new to labview and work on an application where I'm supposed to store an element in an array (without crushing) after each iteration in a loop for. I tried using function Array build, keeping the flag outside the loop for and played with indexing, but did not work. Please suggest me an idea how to do it.

Thank you

It would be better if you attached the real VI.

None of your images show an operation 'insert into array.

How to save a graph after each iteration in a loop for?

Hello

I wrote the code that initializes a spectrometer. Once initialized, if the "Capture" button is pressed, the spectrometer takes a new spectrum three times (see loop for) every second. This spectrum is shown as a diagram in my front. My code works fine... it will update the spectrum every second.

However, I would like to be able to record each of these three iterations in the form of separate graph. Basically I want to click on "Capture" and have my code to save three graphics to a specified folder. How can I do this?

I have attached my VI.

Thank you.

Probably the easiest is to take the data of the for loop and pass out in a tunnel that is indexed. Manipulate the resulting data table you want. You could also do a producer/consumer and write files as the data comes out.

How to reset a variable after each iteration of a loop?

          Scanner keyboard = new Scanner(System.in);
          int num = keyboard.nextInt();

          Factorial aFactorial = new Factorial();
          System.out.println(aFactorial);

What is the problem? Declare the method as "int" instead of "void" and the return value.

How to refresh the table after changing model

My Table of the ADF is limited to a list of dataRows in my SampleDataModel class.
My button is limited to a method of createDataRow of SampleDataModel class.
Then click the button, a new item is added to the list of dataRows.
There is a partial trigger button on the table.
I expect after the button clicked, the table is updated with the newly added row.
But what I see is: new dataRow is added to the list of dataRows and the flashes of the table, but it does not show the line.
Anything I missed? Thank you.

Welcome to Apple Support communities

If I'm not wrong, you want to disable automatic downloads (the feature that automatically downloads all content you purchase all your devices), right? If this is the case, there are different ways to disable depending on the device that you are using:
- For iOS: go to settings-> iTunes and App Store (or App Store), then disable everything under "automatic downloads.
- For PC and Mac: open iTunes, go to Preferences (in the iTunes menu on a Mac) or edit on a PC-> Store menu and disable everything under "automatic downloads.

How to upgrade a table within a trigger
I have a simple question.
Suppose I have the table TAB1 with fields F1 and F2 and I created the following trigger;

create or replace trigger insert_TAB1
After Insert on TAB1
for each line
declare

Tab1 v_F2. % Of F2 type;

Start

...
...
v_F2: =...;
...
...

Update TAB1
the F2 value = v_F2
where F1 =: old. F1;

end;

If I try to insert a record into TAB1, I get:

ERROR on line 1:
ORA-04091: table tab1 is changing, function of triggering/can not see
ORA-06512: at "INSERT_TAB1", line 47
ORA-04088: error during execution of trigger 'INSERT_TAB1 '.

Can you help me?
What I want is to write a trigger that inserts a value into a field after that insert was performed in the table.

Thank you!
Hello

Thank you for this.

The trigger can be written like this
```
create or replace trigger insert_TAB1
before insert on TAB1
for each row when(new.F1 is not null)
begin
:new.F2=..;
end;
```
see you soon

How to upgrade a table which contains 100,000 lines?
Hi all!
I see that I was wrong with column form (GRAG table), namely Gtype: 3003

(MDSYS. SDO_GEOMETRY (3003,50632625, 'null', MDSYS. SDO_ELEM_INFO_ARRAY (1,5,1,1,2,1), MDSYS. SDO_ORDINATE_ARRAY(276.2339,-179.7433,0,276.2498,-179.7361, 0))

And I need to update the Gtype value: 3003 to 3002.
My problem is that I don't know how to implement because the table GRAG has 30000 rows. I can't update the each line manually.

Do you have any advice?
As much as I KNOW oracle11g can simply update SDO_GEOMETRY.

This means creating new SDO_GEOMETRY with old values.

try to change this option (I wrote once to circumvent the cannot not change the SDO_GEOMETRY problem):

--------------------------------------------------------
-geometry of the clones but with different values
-We can "change" the SRID
-Note: oracle 11g cannot change the geometries
--------------------------------------------------------
function alter_geometry (p_geo sdo_geometry, p_srid number default null)
sdo_geometry is back
v_result sdo_geometry;
number of v_srid;
Start
If p_srid is null then
v_srid: = p_geo. SDO_SRID;
on the other
v_srid: = p_srid;
end if;
v_result: = sdo_geometry (p_geo. SDO_GTYPE,
v_srid,
p_geo. SDO_POINT_TYPE,
p_geo. ANSDO_ELEM_INFO,
p_geo. SDO_ORDINATES);
Return v_result;
end alter_geometry;

-and then do an update as
-before test with a table to create in select
Update crack c set c.shape = alter_geometry (shape,...)

How to upgrade the table based on data in multiple tables?

TABLE1:
=======
TXN_ID | NAME
--------------------
TX001 | null
TX002 | null
TX003 | null
TX004 | null
TX005 | null
TX006 | null
TX007 | null
TX008 | null
TX009 | null
TABLE2
========
TXN_ID
-------
TX002
TX004
TX005
TX006
TABLE 3
========
TXN_ID
-------
TX001
TX008
TX009
If TABLE1. TXN_ID present in TABLE2, I should update the form ABC TABLE1.NAME.
If TABLE1. TXN_ID present in table 3, I should update TABLE1.NAME as XYZ.
I can update this by running 2 scripts.
UPDATE TABLE1 SET B.SID = 'ABC' WHERE
IT EXISTS (SELECT 1 FROM TABLE2 B WHERE B.TXN_ID = A.TXN_ID);
UPDATE TABLE1 SET B.SID = "XYZ" WHERE
IT EXISTS (SELECT 1 FROM TABLE 3 C WHERE C.TXN_ID = A.TXN_ID);
How can we do this in a single script? I have more than 10 tables as TABLE2 and TABLE3.
Output should be:
TABLE1:
=======
TXN_ID | NAME
--------------------
TX001 | XYZ
TX002 | ABC
TX003 | null
TX004 | ABC
TX005 | ABC
TX006 | ABC
TX007 | null
TX008 | XYZ
TX009 | XYZ

Assuming a table2 and table3 will not have same tnx_id you can do.

merge into table1 t1

a_l'_aide_de)

Select txn_id

name

Select txn_id, "TABLE2" name

from table2

Union of all the

Select txn_id, name "TABLE3."

table 3

)

) t2

on)

T1.txn_id = t2.txn_id

)

When matched then

set t1.name, t2.name = update

How to upgrade a table which includes nearly 1 Million Records

Hello

Take the base for our Referenece emp table and allows to assume that it contains about 60000 Records and all the deptno in this table are out of 10. Please allow an update statement that would update the deptno column in the table EMP ((according to) order by EMPNO) in each increment of 1 120 reviews. (DeptNo to be incremented by 1, 10, 11, 12, etc.).

First 120 deptno records should be 10,
Then 120 deptno records should be 11 and so on.
.

For the last 120 deptno records should be updated with 500.

Please notify.

Yes, I slide collections and was trying to reach somwthing on similar lines to which you provided the code example...

My essay is equipped to take a collection: initialized with values of say 3-4...

Take other tables... A column... and update the column in the table (not PK, FK anything) using the values of the initialized collection...

However, I am stuck between the two on how the UPDATE clause should be...

OK, if it's just because you want to practice with collections, you might do something like this...

Of course, there is treatment rank by rank and is not best for performance, but it allows you to access your collection that you created names.

Save the data of State machine after each iteration, then write all the data at once

I have trouble finding in the best way to manage data generated by my state machine. Here are the data that it will save:

* When pressure is set, a set point is returned.

* When the pressure is set, a reading is taken a multimeter.

What would be the best way to do this? Would it not be better to store all the data in memory, and then write all the data at once? If so, what would be the best way to do this? I want to use the tool to generate report after have set all the pressures. I joined my current application. Thank you all!
