Thank you very much in advance
If you consider how identical to and WHERE the clause is, I think that avoiding the UNION would be best. (that is to say with the UNION, you are reading/pulling the same data 3 times.).
I would try to fire once, then 'create' what data you need. Without overflow or what you're trying to do... I would think something like that would back up the same results. (Not sure on performance, but again, I do that think that he would run faster? :))

Is it possible to reduce the "suction" items fall dragged and drop?
I am developing a game where the user must correctly space objects between them depending on what is their relationship to each other. Falling objects are in fact completely transparent, and the user must place the point slide perfectly on top of it. The problem is that when the user does not place the object from sliding directly on top of the object to be moved, it nevertheless gets pulled to this object. 1. I want that there is virtually no traction power. 2. I would also like the user to be able to stream, click on the object to move and move it slightly until he thinks it's perfectly fine and the stay of the object where it let him down - I don't want it pulled back to its origin.
If possible, let me know!
Thank you!

Hello
It is possible to redrag and withdraw the power of pull by setting the following two parameters.
1 Select the Target Drop, Drag and Drop Panel > accordion target Drop, change of position as "absolute".
2. activate the option "Source Redrag dropped" to drag and drop the Panel > accordion Interaction properties.
But with these parameters, it allows to drag the object even when it is removed properly.
Thank you

Reduce the size of a file created by "write to waveform.
Hello
I'm using labview in 2012 and I have a problem with the size of the tdms file generated by the function "write to waveform. The data is real time 16 channels in a series of X NI USB-6343 and is composed by the gains of the voltage on the y-axis with the absolute time on the x axis (waveform format). The size of the file is reached a Go command within a few hours. Is it possible to reduce the size of this file? All configurations on the component?
Thanks for the help.
Best regards
Marcelo Nobre
Yes indeed, there is a better way. Instead of using writing on file express VI measure, try adding the DAQmx logging into your task DAQmx (before starting the task):
This method writes the raw binary data unadjusted to the file (2 bytes per sample because it is a 16-bit data acquisition card) with scaling of information in the header of the file. In the example you posted, you write the data which are already put across to the file (double 8 bytes for example). What will make this change you expect to reduce your file size by ~ 4 x.
If you wish you can compress the files once you have finished writing to them for further reduction of size, but there is no support to achieve so that you are currently writing in the PDM file. In addition, you will need to unzip the file until you can access the data in the .tdms file. You can probably get good results with something as simple as the data stored in a .zip file.
Best regards

AmritHi, Amrit,
Do you want to just 9 copies of the selected lines of mth_dim_hierarchy, each with all the columns the same except for level_num?
If so, mth_dim_hierarchy with a Meter of Table , that is, any table of cross join (or, as in this case, result set) with 9 rows. For example:WITH cntr AS ( SELECT LEVEL AS n FROM dual CONNECT BY LEVEL <= 9 ) SELECT c.n AS LEVEL_NUM , To_Date ('01-JAN-1900','DD-MON-YYYY') AS EFFECTIVE_DATE , -99999 AS LEVEL_KEY , 'Unassigned' AS LEVEL_NAME , -99999 AS PARENT_KEY , 'Unassigned' AS PARENT_NAME , MDH.HIERARCHY_ID FROM MTH_DIM_HIERARCHY MDH CROSS JOIN cntr c WHERE MDH.CREATION_DATE >= v_log_from_date AND MDH.DIMENSION_NAME = 'EQUIPMENT'
I hope that answers your question.
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.
In the case of a DML (such as FUSION), the sample data should show what look like the paintings before the DML, and results will be the content of the or the tables changed after the DML.
Explain, using specific examples, how you get these results from these data.
Simplify the prole, if possible. If you show what you need to do with 3 distinct values of level_num, do not post a problem with 9 distinct values.
Always tell what version of Oracle you are using. -

How to reduce the size of the SWF to a file imported from After Effects
Hello!
I'm doing a banner web for an internet marketing company, so he has very specific requirements. We did it in After Effects, and I was able to export it to an FLV file and import to Flash very well with the SWF file. Now, I need to make the significantly smaller SWF file.
At the moment it is 2.5 MB and we can only present a 40K SWF size. It is even possible to reduce the size so much and still keep intregrity of the animation?
I'm more familiar with Flash than After Effects, but he can play with the settings, etc. If someone can tell me what to try.
Thank you very much for your help!
is the flv almost 2.5 MB? If so, your only option to significantly reduce swf size is to load the FLV dynamically (which is not usually allowed with banner ads).

How to reduce the size of the file to an existing PDF?
Hello
Any kind soul suggest a solution for this? Or is it not possible to do?
I have a PDF - 7 MB file, is provided by a third party (so I can't get another copy or the content has been created between), I would like to add to a site, and 7MB is just too.
It is 19 pages, can anyone tell me if it is possible to reduce the size of the file to something more reasonable?
I tried to optimize and she went from 7.92 MB to 7.90 MB wow!
Thanks to the McP Adv.
A lot depends on how it is done. Here are some options: (remember to work on a copy)
1. save money, not save
2 Save as > optimize PDF (you can optimize sample image and other. (There is also a function of audit (here I think for AAX) which gives you an idea where is indigestion)
3. Save as > reduce the size of the file
4. printing to a new PDF with appropriate work settings (not recommended normally and will delete the links and others)
