To compare the name of the control with a variable

Hi all

I want to compare the name of a control with a variable in a loop. Is there any function for it in Labview? Please let me know if it is.

Thanks in advance

When I subtract two numbers DBL and try to compare the result with another DBL, it fails

I found a curious problem with subtraction and compare numbers DBL in LabVIEW (8.6). Here's how it works:

1. subtract two numbers DBL such that the result is not incorporated. (Say, 3.2 - 3.1)

2. compare the result with a constant/control that is on the result of the subtraction (in the example, 0.1)

3 see the output of the comparison.

If the result of the subtraction is an integer, the Boolean result is (as expected). If the result is not complete, the comparison fails.

(Now, if I simply compare two floating point numbers, it works, so the issue is not with the node comparison itself, but with the data that is entered to the node). Can someone understand why this happens? It's unexpected, it's a pretty serious bug.

It is provided with all programming languages. Numbers do not have an exact binary floating-point representation. This has been discussed endlessly. Never use the equal function with floats. You can use the function in the range and force.

Compare the Collection with the help of the Table less

Hey there!
my plan is to transfer an excel file and record in an apex_collection, compare the results with those that already exist in a specific table and write it in another temporary table.
Import excel, in the collection works perfectly, but I fight with the comparation. I select the form of entries collection and using UNMIS to compare lines with those of another SELECTION that gets the lines of the existing table.
DECLARE
BEGIN
INSERT INTO UPLOADED_DID_LIST_COMP (BAC_CODE, UPSC)
(
SELECT BAC_CODE c001
c002 published
From apex_collections ca
WHERE collection_name = "UPLOADED_EXCEL."
LESS
SELECT
BAC_CODE
EDITED
OF UPLOADED_DID_LIST upld, apex_collections c WHERE
collection_name = "UPLOADED_EXCEL."
AND the upld. BAC_CODE = c.C001
AND the upld. LʼUPSC = c.C002
);
End;
This does not work because of this error:
ORA-00933: SQL command not properly ended ORA-06550
PLS-00103: encountered the symbol "end-of-file" when awaits one of the following numbers: (begin case declare exit end exception for goto rise back loop mod null pragma select update while < ID > < a quot double)

If it's a copy/paste of your exact code then you just need to fix it, spaces here and there. And remove the superfluous where clause. Maybe:

BEGIN

INSERT

IN UPLOADED_DID_LIST_COMP

(

BAC_CODE, SCHOOLING

)

(

C001 SELECT BAC_CODE, EDITED C002

FROM APEX_COLLECTIONS CA

WHERE COLLECTION_NAME = "UPLOADED_EXCEL."

LESS

SELECT BAC_CODE, SCHOOLING

OF UPLOADED_DID_LIST UPLD

);

END;

Good luck.

compare the control unit when obtained from scriptures Sub
Dear,

I'm working on oracle apps R12, and I two business units when do two bills of different operating units and transfer to the GL, how do I compare journals it is for a specific operating unit in the database is there any ID in the database that I can compare different operating unit transactions that come from the sup to the GL book.

Thanks in advance,
Hello

Ledger doesn't store information directly on the control unit which is normally captured at the transaction level.
However, there is a table called GL_IMPORT_REFERENCES that keeps track of each worksheet that is passed from subsidiary ledgers to the General Ledger. This table has a column GL_SL_LINK_ID... This can be compared with a few tables over to reach the transaction source and pick up the reference of operating unit...

(1) for the sheet, you want to know the GL_SL_LINK_ID of table GL_IMPORT_REFERENCES...
(2) once GL_SL_LINK_ID is obtained, use the value in the XLA_AE_LINES table and collect the AE_HEADER_ID value...
(3) once the AE_HEADER_ID value is obtained, use the value in the XLA_AE_HEADERS table and capture the value EVENT_ID...
(4) once the event_ID value is obtained, you can check it with the ACCOUNTING_EVENT_ID of the base transaction... table column for accounts payable invoice it would be AP_INVOICE_DISTRIBUTIONS_ALL and for the payment of accounts payable AP_CHECKS_ALL... Similarly for other modules, the basic transaction tables would hold the reference... .Similarly each transaction table at the level of the subledger database allows to store the ORG_ID which is your value of operating unit...

In addition, if your users provide a name for the JOURNAL by operating unit during the transfer of auxiliary accounting journal entries in the log book, you can identify by the same...

Kind regards

If I replace the control with another why DAQmx create channel once complain a false claim?

I tried to replace the frequency by another control in the example found here complete PWM:

http://www.NI.com/white-paper/2991/en

However, I get the following error message:

Possible reasons:

Requested value is not supported for this property value. The value of the property may be invalid because it is in conflict with another property.

Property: CO. Pulse.Freq
Required value: 0.000000
Valid values begin with: 22.300000e - 309
Valid values ending with: 20.0e6

Channel name: Dev1/ctr0

Task name: _unnamedTask<10>

My wiring diagram looks like this:

If I cancel my change (i.e. I have remove the frequency control knob and turn it over to the control of the example, it works perfectly.) I get the waveform is displayed in the oscilloscope.

My goal is to simply use a frequency and duty cycle control knob. How can I achieve this?

There are two things to do.

What I think you did now changes the scale of the handle.

You will also need to change the values that are allowed to enter. You will do on the data entry tab in the dialog button properti.

Uncheck the 'use default', the Minimum value limits and Maximum identical to your balance.

Value "Response to value out of range" Coerce to both Minimum and Maximum.

I hope this helps.
Let me know if you have more problems.

How to compare the U2412M with the old 2407FPW?

I had the 2407FPW since ' 07 and love it. I like the picture not bright. I'm about to order a new Dell and I wonder if the U2412M is comparable in quality? It has the same resolution (1920 x 1200), in contrast to the other Dell Ultrasharp 24 "monitor that is only 1920 x 1080.

Do you want user input in the command of the COIL, or want you she in the query?

What are the data type gen_date of the oif?
If it is a string, it is a big mistake. Information about the dates in the DATE columns belongs.
If it's a DATE, so don't try to compare strings, such as "2012-11-01 00:00:00:00000'."

spool off;

One way to do that is with substitution variables:
```
...
SET     VERIFY  OFF

ACCEPT  start_gen_date     PROMPT "Starting date (e.g., 2013-02-18 23:00:00.00000): "
ACCEPT  end_gen_date     PROMPT "Ending date   (e.g., 2013-02-18 23:59:59.99999): "

SPOOL  spool_results.csv

SELECT    *
FROM        gui_site_journal
WHERE        gen_date  BETWEEN '&start_gen_date'
                AND     '&end_gen_date'
ORDER BY  gen_date;

SPOOL  OFF
```
There are security considerations. Variables substitution to the devious users the power to issue a SQL, such as DROP TABLE command. Users with SQL * Plus access already have this power, anyway.

Simulation & Control with local variables

Why should I use a local variable in a loop of simulation, but not in a Subvi simulation?

Local variables will only work in a Subvi are those that relate to controls or indicators located in the Sub - VI. If you need to pass data between different from the Subvi, so you have several choices.

1. common variables, as you said.

2. global variables, as you said.

3. pass the data in or out through the pane of the connector of the Subvi.

4. functional Motors Global Variables/Action.

5 lines of

6. the references to the controls in the VI main so that they be used with nodes of property in the Sub - VI

by comparing the records with another table

Hello
I have the following 2 tables (test_prs & test_dep) and registers
My goal is to compare test_prs with test_dep records and return the records that are not in test_dep

Here is the table scripts

create table test_prs (id ,p_id ,r_id)
as
select 1,200566,200566 from dual
 union all
select 2,200567,200567
from dual

create table test_dep (id,de_typ,de_id,de_u_typ,de_u_id)
as
select 10,'AS',200566,'PG',200566
FROM DUAL
UNION ALL
select 11,'AS',200567,'PG',200567
FROM DUAL


insert into test_dep 
select 12,'AS',400189,'PG',400273 FROM dual union all
select 13,'AS',400273,'PG',400250 FROM dual union all
select 14,'AS',400273,'PG',400192 FROM dual union all
select 15,'AS',400273,'PG',400191 FROM dual

insert into test_prs
select 3,400273,400273 from dual

I tried the following query to meet my criteria. My output should be null, but all records

select * from 
test_prs  prs
where  exists (select 1 from test_dep de where de.de_id !=prs.p_id and de.de_u_id !=prs.p_id )

Could you please help me the same

Smile says:
Thanks for the request

The query does not work with the following documents
insert into test_dep
select 16,'AS',750664,'PG',750758 FROM dual 

insert into test_prs
select 4,750758,750668 from dual
the r_id should not be put in correspondence with the columns in the test_dep table. P_id must only be put in correspondence

OK, you want to match against the de_id and the de_u_id p_id? Or a line where either p_id concordances r_id de_u_id or de_id must not be returned?

To match p_id against de_id and de_u_id, you can write the query like this:

select id, p_id, r_id from test_prs where
p_id in
(select p_id from test_prs
minus
select de_id from test_dep
minus
select de_u_id from test_dep);

By comparing the date with the BIGGEST rows
Hi all
Why don't the last statement asking all values?
Suppose that:
```
 SQL> select * from test;

TEMP_DATE
---------
14-APR-11
15-APR-11
16-APR-11

SQL> select months_between(to_date((select temp_date from test where rownum=1)),to_date((select temp_date from test where rownum=2)))test from test;

      TEST
----------




 
```
I try to get the biggest date of temp_date column of the table of test, but instead, I myself dump of null values. What has gone wrong?
Is there a way more easy to compare these values using GREATEST (I can do that easily with the MAX function however)?

Best regards
TA.

Hi, Val,

Valerie Debonair wrote:
... I try to get the largest temp_date column of the table of test date...

The simplest approach, which is
```
SELECT  MAX (temp_date)   AS greatest_date
FROM    test;
```
but instead, I got dump of null values. What has gone wrong?

As someone has already said, ROWNUM = 2 will never be TRUE. ROWNUM is 1 until a line was selected; then only does ROWNUM get incremented to 2.

Is there a way more easy to compare these values using GREATEST (I can do that easily with the MAX function however)?

To use the LARGER, you will need to rotate all values not NULL on a single line. It's a very bad idea. In fact, people sometimes unpivot data just so that they can use MAX instead of GREAT.

Why do you want to do more BIG?
If you use it, be careful for NULL values, because BIGGER returns NULL if one of its arguments is NULL.

Select all the text in the control with AS3
Does anyone know how to select all the text in a text control (text, textarea, etc.) with AS3?

Thank you.
Answered my own question.

Set the properties selectionBeginIndex and selectionEndIndex of text controls.

For example, this selects all the text in a text box:
yourTextArea.selectionBeginIndex = 0;
yourTextArea.selectionEndIndex = yourTextArea.text.length;

(2) declare
n_table table % rowtype;
n_table ins_table;
Start
Select * BULK collect into ins_table

Please notify. and comeout with valid arguments.
Thank you

If the destination table is empty, then you can do ETG (CREATE TABLE AS SELECT...). This would be by far the fastest way. But to choose one of the choices you gave, the top hand is the first.

The second option is a very bad idea. Collection of PL/SQL uses PGA. Millions of PGA data costs very expensive. And also this approach doesn't give not any kind of performance on simple INSERT INTO SELECT...

By comparing the Date with timestamp without time portion

Hello
I have table lets say rates, it has a field called expire_date. Now, I need to display the records in this table which expires date is greater than today. Can someone tell me how to do?
Currently, I do like this:
Select * rate where expire_date > = (select SYSDATE from DOUBLE);
This request is now selection of records whose timestamp is greater than the current date and time and other drops while the expire_Date is today with less time stamp.
I need to show the records that are valid today and coming dates regardless of today
Kind regards
Ashish

Select * rate where expire_date > = trunc (sysdate);

Avoid the misuse of the double

Kind regards

Hello

Here's a way to do it:
```
SELECT      x.ID
,      x.VALUE
FROM      x
JOIN     t     ON      ',' || t.value || ','
          LIKE     '%,' || x.value || ',%'
;
```
Extra commas are necessary to avoid the problem of 'mother is in chemotherapy,' when a single value can be one substring of another. If this is impossible (as in your case, where all values are exactly 3 characters) then you don't have them.
