Using the eval() function in Table DDL Transformation Scripts

Hello

I would like to run a stand-alone file java script in the script after you create and the events of the end of the Script. According to the Oracle documentation, there are several ways to do so: https://docs.oracle.com/javase/8/docs/technotes/guides/scripting/prog_guide/api.html

Only the first way seems to work:

Suggestions, please

Alek

Hi Alek,

you try to use the JavaScrpt JavaScript eval() function eval() function

and as I see that it works as expected. You need to get your engine and use the eval function.

Following works for me:

var manager = new Packages.javax.script.ScriptEngineManager();
engine = manager.getEngineByName("nashorn");
s = engine.eval("1+2");
fr = java.io.FileReader("d:/temp/inc.txt");
k = engine.eval(fr);

How can I use the BCGTransform function to treat the 16-bit Image?

Hi ~

I use LabWindowsCVI8.5 and NI Vision to make the treatment of the Image. When I read the "IMAQ Vision for LabWindowsCVI Reference Manual", I found that the imaqBCGTransform function only supports 8-bit Image, while I do the BCG to turn on 16-bit image. Are there solutions to use the BCGTransform function to deal with the 16-bit Image? Or any other feature that could make the correction Gamma, contrast and brightness on the 16-bit Image?

Thank you very much!

because imaqBCGTransform is implemented as a lookup table, we can understand why it is limited to 8-bit images.

Now let's take a look at the definition of each of this mandate (from the NI Vision Concepts documentation):

-brightness: a constant added to the components red, green, and blue pixel of color over color, decoding of the process;

-contrast: a constant multiplication factor applied to the components of the luma and chroma of a pixel of color in color to decoding process.

-gamma correction: expand high gray-level information in an image while removing information of low level of gray. (the chapter on lookup tables gives some examples of corrections gamma)

now that you understand that this transformation is a simple mathematical function, simply calculate the correction for each pixel on your 16-bit images.

I know not the exact formula used by the imaqBCGTransform function, but you should be able to approach by performing some tests on images 8 bits with the original function... or you can make your own formula... or find one on the net... or you can ask someone at home OR you give the formula...

How do we use the SUBSTR function in OWB
Hello, I'm pretty new to OWB. I need to use the SUBSTR function in owb. My source table has 16 characters in length. But in my datamar,.
the length is 14 years. I want to the substring from source to the destination. The mappings are already developed. I need to change the mapping to make sure that,
It brings only SUBSTR (1.14) mini - DW.

Any help is appreciated.
Use the operator of expression between two attributes.

OWB has already SUBSTR as a preset transformation

I would like to copy a table that is in a non-protected PDF document using the paint function in accessories to paste it in a Word document that I'm working on. Please help as soon as POSSIBLE.

Hello, Edward Namalima,.

3. a copy of the screen has now sent in the windows clipboard.

4. now open Paint.

5. on the Paint toolbar, click on edit and then click on paste. The image will now be pasted in a Paint window. You may need to accept a dialog resize if the image is larger than the current document.

6. now, from the toolbar to the left of your screen, click on the Selection (the oblong dotted box) tool. With the selection tool, select the entire surface of the table you want to copy. Once selected, click on modifier change again, then select Copy.

SQL using the analytic function

Hi all
I want a help in the creation of my SQL query to retrieve the data described below:
I have a test of sample table containing data as below:
State ID Desc
MICHAEL 1 T1
ACTIVE 2 T2
T3 3 SUCCESS
DISABLE THE T4 4
The thing I want to do is to select all the lines with an ACTIVE status in the table but is there is no ACTIVE status, my request will give me the last line with MICHAEL status.
I can do this in a single request by using the analytical function for example, if yes can yiu help me on the request of unpacking.
Kind regards
Raluce

Something like that?

I had to fix it.

with testdata until)
Select 1 id, "T1" dsc "DISABLED" status of Union double all the
Select 2 id, 'T2' dsc, the status "ACTIVE" of all the double union
Select id 3, "T3" dsc, the status of 'SUCCESS' of all the double union
Select 4 id, "T4" dsc "DISABLED" status of double
)

Select
ID
dsc
status
of testdata
where
status =
-case when (select count (*) in testdata where status = 'ACTIVE') > 0
then 'ACTIVE '.
Another 'DISABLED '.
end
and)
ID in (select id from testdata where status = ' ACTIVE')
or
ID = (select max (id) in testdata when status = 'DISABLED')
)

STATE ID DSC

'2' 'T2' 'ACTIVE '.

Maybe it's more efficient

Select
ID
dsc
status
of testdata
where
status =
-case when (select count (*) in testdata where status = 'ACTIVE') > 0
then 'ACTIVE '.
Another 'DISABLED '.
end
and
ID =)
-case when (select count (*) in testdata where status = 'ACTIVE') > 0
then id
on the other
(select max (id) in testdata when status = 'DISABLED')
end
)

How to use the NVL function to a parameter with comma delimited values

Gurus,
It is confusing to me. I am trying to use the NVL function, but the setting that I'm passing in my cursor contains multiple values with commas. The NVL function is confused when analyzing the values.
'Where' cursor clause...
and nvl (sn.c_attribute1,'x@#$%') in nvl (p_desig,'x@#$%'( )
translated parameter values...
and nvl (sn.c_attribute1,'x@#$%') in nvl ('SPRT''GOOD' 'BAD' 'x@#$%') -NVL does not parse the value correctly
Any idea on how to get NVL recognize 'x@#$%' , if p_desig is null?
Thank you
Scott

HI, Scott.

Whenever you have a problem, please post a small example data (CREATE TABLE and only relevant columns, INSERT statements) of all the tables involved, so that people who want to help you can recreate the problem and test their ideas.

Also post the results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.

Always say what version of Oracle you are using (for example, 11.2.0.2.0).

See the FAQ forum: https://forums.oracle.com/message/9362002#9362002

My best guess, based on what you posted bone is present, that your problem is discussed in the following:

How can I use the SUM function to calculate the number of employees in the comp. & deptnt?

I have two tables: employees and their departments. I'm figuring the total employees by the Department and the total employees of the entire society. I know I have to use the SUM function, but I can only calculate total employees by Department and company separately. I need to get this result:

DEPT_NAME     DEPT_TOTAL_SALARY         COMPANY_TOTAL_SALARY
RESEARCH                  10875                        29025
SALES                      9400                        29025    
ACCOUNTING                 8750                        29025      


This is my code:

SELECT department_name, SUM(salary) as total_salary
FROM employee, department
WHERE employee.department_id = department.department_id
GROUP BY department_name;

SELECT SUM(salary)
FROM employee;






Can somebody help please?
Thank you in advance.

Hello

Something like:

SELECT dname,
       dept_tot_sal,
       SUM (dept_tot_sal) OVER () comp_tot_sal
FROM   (SELECT   dname,
                 SUM (sal) dept_tot_sal
        FROM     dept, emp
        WHERE    dept.deptno = emp.deptno
        GROUP BY dname);

There might be a smarter way, with no re - select.
