Please help me.

Hello

Welcome to the forum!

If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).
See the FAQ forum {message identifier: = 9360002}

I think you want an outer join partitioned (to make sure that all dates are represented for all values in col1) and the analytical LAST_VALUE function, like this:

WITH     all_dates     AS
(
     SELECT DISTINCT  dt     -- DATE is not a good column name
     FROM              table_x
)
SELECT       a.dt
,       x.col1
,       LAST_VALUE (col2 IGNORE NULLS) OVER ( PARTITION BY  x.col1
                                                ORDER BY      a.dt
                               )           AS col2_shown
FROM             all_dates  a
LEFT OUTER JOIN      table_x    x  PARTITION BY  (x.col1)
                               ON  x.dt = a.dt
;

If you would care to post CREATE TABLE and INSERT statements for your sample data, and then I could test this.

Get the Max values and average of the different cycles in the single channel

Hello

I'm trying to get the Max values and average of the single channel that has different cycles it contains. I tried to use commands such as Chnclasspeak3 and chnpeakfind, but they were not useful for me. What I need is the Max values and average of the different cycles numbers saved in the data channel.

Exampld if the string contains 5 numbers of repetitive cycles, then we must find the maximum values and the average of these 5 cycles in the single channel. Attached reference data. This is the .raw file and I have the plugin for it to use in diadem 11.1.

How to get the Max value in Essbase
Hello

I have problem to get the max value of 3 years in Essbase.
How can I get the max value of Dec 2009, Dec 2010, Dec 2011.
Suppose the value of Dec 2009 = 1000, dec 2010 = 1500 and Dec 2011 = 2000
I want to get the max value of these three value, how can I do this in the Essbase calculation Script.
Any idea?

Thank you.

Kind regards

Joni
You did not specify if year and period are there separate dimensions, in any case as always a number of different possbilities and I don't have much time today to think about, but only one method can be to use @MAXRANGE

DIFFICULTY (other members to set, 'Dec')

'MemberToStoreAgainst' = @MAXRANGE("MemberToFindMaxRangeFor","2009:"2011");

Depends on how you feel on one of the links of:
```
SELECT name, value
FROM (SELECT name, SUM(value)
      FROM table
      GROUP BY name
      ORDER BY 2 DESC)
WHERE rownum = 1

SELECT name, SUM(value)
FROM table
GROUP BY name
HAVING SUM(value) >= ALL (SELECT SUM(value)
                          FROM table
                          GROUP BY name)
```
among many other methods. The first takes a single arbitrary registration in the case of a tie, and the second shows all the related records.

Get the MAX value of dimension 2 table
I have a little trouble to find a value MAX (or MIN) of the second dimension in a 2-dimensional array. I do a query and the first dimension is the column name, the second is the values. I'm coming out of the MAX value of the column in the second dimension. ArrayMax said "the array passed cannot contain more than one dimension."

Any ideas? I'm sure that this is possible.
MaxValue = ArrayMax (QueryName ["FieldName"]);

or Q of Q.

How to get the Max value with other columns data also.

Suppose that a query is covered with the data as
Time of ID

03 16/07/2014
04 07/07/2014
I need to get the ID and time to time max.
that is, should I get
Time of ID
03 16/07/2014
To do this, I wrote a query that gives me necessary data. But I thought that's the best way?
Is it an effective way to get this data?
My query that returns the data required is:

(
Select 'DUMMY', ID, TIME1, MAX (TIME1) OVER (PARTITION 'DUMMY') AS MAX_DT FROM TAB1

get the max value

Hi all
I have the following data

with table1 as

  select to_date('01/01/2010', 'mm/dd/yyyy') dt, 2 cid from dual

)

I would like to write a query that gives me the dt max with the corresponding id.
for example, if I specify to_date (April 1, 2010 ', ' dd/mm/yyyy') then the output should be

CID DT
===============
2010-03-01 3

If I said on 02/01/2010 then the output should be

CID DT
===============
01/01/2010 2

as you can see, I want max < specify the date. I also specify the corresponding cid which belongs to this date
can someone help me write a query that gives result above

Get the highest value of acquired data

Hi, how can I get the highest value of data according to data acquired using the accelerometer ADXL345 and LINX in LabVIEW?

I want the highest data to be shown with a flag. However, the data being shown are always the last acquired data. My problem would be what happens if the highest data somewhere at the beginning or in the middle of all the acquired data? How to display the highest data using an indicator?

Here's a look at my front, block diagram, and sample of the acquired data.

From the front panel, the basic indicator of detected last poster 0.1929 (amplitude), which is the last value. But looking at the Excel file, the highest data are data which is 0.2013. The highest, I want to be displayed on the indicator not the last value. How do I do that?

Thank you!

I gave you an example of what you need to do - it is not okay if wire you the new value and the old value for the X or Y - it will always return the maximum of the two values so the order doesn't matter. It would have been more useful if you had posted what you tried the max & min. You need a registry to offset inside the loop (like I did with my while loop). If you only want to display the maximum value for each iteration of the loop for external, you must initialize the shift register by plugging a 0 to its terminal on the left. A shift register her pinned the value of the last run - probably not what you want here.

How to get the Max of elements of type datetime value

But it does not work on the datetime data type.
Any help in this regard is highly appreciated.

How can I get the max of a measurement value

How can I get the max of a measurement value?

http://forums.NI.com/T5/LabVIEW/how-can-I-return-the-maximum-value-from-a-voltage-sensor-over/m-p/30...

I tried the while loop max-min-solution described in this link. But this using my myRio acceleration measurement no longer works. It seems to hang.

I use the I2C Communication.

The inner circle while loop is a bad construction. It will be either executed once, if enter the Boolean value is True, or forever if the value is false.

Put your records on the timed loop shift and eliminate inside while loop. Then your code should work.

To get the old value and the new value

create table test (ID NUMBER,
Number of REV,
Number FIELD_ID,
FieldName varchar2 (200),
ACTION varchar2 (50).
Field_value varchar2 (200),
MODIFIED_BY varchar2 (50).
Date MODIFIED_DATE);

Insert into TEST (ID, REV, FIELD_ID, FIELD_NAME, ACTION, FIELD_VALUE, MODIFIED_BY, MODIFIED_DATE) values (1007,283,12,'status','UPDATE','Started','2002',to_date('13-DEC-13','DD-MON-RR'));
Insert into TEST (ID, REV, FIELD_ID, FIELD_NAME, ACTION, FIELD_VALUE, MODIFIED_BY, MODIFIED_DATE) values (1007,224,12,'status','UPDATE','preview','2002',to_date('12-DEC-13','DD-MON-RR'));

Hello

It seems that you are not interested in the MAX at all. Looks like you want to classify the lines, such as one that has the lowest value is assigned the number 1, the 2nd line with the lowest values gets 2,... and line with him gets N-th lowest value N. If is not serious if the MAX is 4, 2 or 420.

Here's a way to do it:

SELECT T.*

, RANK () OVER (PARTITION BY r_nm, r_obj)

ORDER BY val

) AS rk

T

ORDER BY r_nm, r_obj

val

;

Depending on how you want to deal with links, you can use ROW_NUMBER or DENSE_RANK instead of RANK.

Get the max of a field in a query of County

Hi, I work with the following SQL query:

WITH ORDERED_QUERY AS

            SHRTRIT_SBGI_DESC AS "INSTITUTION"

ORDER BY "COUNT OF I" DESC
)
SELECT "COUNT OF I","SBGI CODE","INSTITUTION" 
FROM ORDERED_QUERY
WHERE ROWNUM <= 20

What follows is the table mark code to get a test table:

create table SHRTRIT
(
SBGI_CODE     VARCHAR2(6)     NOT NULL
SBGI_DESC     VARCHAR2(10)
ACTIVITY_DATE     DATE
)
/
INSERT INTO SHRTRIT

{CODE}

What I'm trying to do is get the max ACTIVITY_DATE for the institution when it's listed. For example, the max ACTIVITY_DATE for MING-CHUAN COLL is 2/10/2009 3:00:15 AM. The desired output is one record for MING-CHUAN, with a count of 4, the SBGI code, the Institution Name, and the max activity date of 2/10/2009 3:00:15 AM. However, when I just insert MAX(SHRTRIT_ACTIVITY_DATE) as part of the in-line query, it doesn't work like you'd think. It makes separate records for each date, such that here, there would be one record for 2/10/2009 with a count of 2 and one record for 10/6/2007 with a count of 2 for MING-CHUAN. 

It might actually work with this small amount of data, I don't know because I can't make a test table with these few records to find out. It certainly isn't working with the actual table. I know it has something to do with the aggregation, but I'm not quite sure how to get around this problem. I've tried some different things, but none of them have gotten the desired results.

Any help that you might be able to provide would be greatly appreciated!

Get the current value of the variable when reaching CNVCreateSubscriber

I use CNVCreateSubscriber () to create a subscription read to a network Variable: whenever the value of the variable changes, the DataCallback is called and I'm able to get the new value of the variable.

But how to get the value of the variable when a subscription is created?

I read in the help CNVCreateBufferedSubscriber () returns this information, but I wonder if using CNVGetDataFromBuffer () in a polling loop has the same performance as the approach to DataCallback of CNVCreateSubscriber ().

In addition, the dataStatus (CNVGetDataFromBuffer) parameter is different for different Subscribers? (that is if I have multiple subscribers, CNVStaleData is related to the specific Subscriber or is a global property of the variable)?

CNVData data;

CNVGetConnectionAttribute (customer, CNVMostRecentDataAttribute, &data);)

Get the default value for class LV 1498 error

I call get the Default Value.vi LV class to dynamically load a class.

It was working fine until I added Open Config Data.vi to read an .ini file.

The application works fine when I press the button RUN in the LabView development environment, but when I create the executable file with Application Builder and then run it, I get:

"1498 error occurred getting class LV Default Value.vi"

Possible reasons:

LabVIEW: Library has errors. Correct the errors before performing this operation.

«"" "String of full appeal:»»"»

Download LV class by default Value.vi

Test.VI

LabVIEW has tried to load the class in this path:

g:\cal\devices\Digital300Meter\Digital300Meter.lvclass

I narrowed the problem down to open Config Data.vi included in the application, not in the class. I don't have to call the Open Data of Config vi to get this error.

I have a Subvi, called "SelectDevice" which refers to Open Data from Config. In my main Test.vi SelectDevice is in the true case of a true/false case structure, which is set to False.

If I put a design schema off around the Open Data of Config vi, I do not get the error.

I suspect that including Open Config Data include a VI in the application that interferes with the LV ranks by default.

Thank you, it works!

I also put the additional Exclusions page as follows:

Disconnect the type definitions - verified

Remove unused polymorphic instances of VI - verified

Remove unused libraries project - members verified

Change the project library file after removing unused members - unaudited
