Please tell us how the query above can be changed to produce the result to wait.
Thank you
Hello
So, you want to see all the tbl1 lines, if they have a match in log1, and for the grand total of lines, you must count the log1 lines if they have a match with tbl1. This looks like a job for a FULL OUTER JOIN:
SELECT t.status
EARL of (l.status) AS cnt
OF log1 l
FULL OUTER JOIN tbl1 t WE t.status = l.status
GROUP OF ROLLUP (t.status)
HAVING t.status IS NOT NULL
OR of a GROUP (t.status) = 1

Satellite L650-1GF - cooling fan runs every 3 minutes
Last week, I bought a Satellite L650-1GF. Everything is fine except the noise from the cooling fan. Especially because it works almost every minute to cool the carrots. There is an annoying sound hum which takes about 10 seconds and is repeated every 3 minutes approximately.
I checked with "Speedfan". The temperature of the hearts is fluctuating between 32 and 37 C. And at about 37 ° C, the fan speed to cool the computer.
Two questions:
1 is this normal that the cooling fan starts cooling to 37 ° c.
2. is the annoying noise of the fan normal for this model of Toshiba?And what is acceptable, can I find examples to compare with what I feel here somewhere? I saw a lot of cell phones so far, but none of the cooling fans made a buzzing sound like this.
Kind regards
Jaco
HollandHello

You can do this in Windows power management, but make sure you do this for the current profile of the power.

Need to show daq reads per second, but only to record a reading every 10 minutes, need help
You are also looking to taste to 1 Hz data acquisition?
My approach would be to use the DAQ acquisition to time your loop display reading each acquisition, then use the loop counter to control the logic of your writing to file. For 1 Hz and 10 minutes write I would use 'quotient and remainder' I / 600; If rest = 0, then write the data point.
For the date and time, under Calendar palette use the time get in seconds food a DateTime Format to a string.

I use Windows 7 and 8.0.1 Firefox on a PC. It's frustrating. I like Firefox, but it keeps popping up every 10 minutes when it is minimized and I work in another program. I can't continue to use if it cannot be repaired. I just changed from 3.6 and never had any problems. In addition, no settings have been changed.
Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).
- Makes no changes on the start safe mode window.

Every few minutes (sometimes in less than 60 seconds, Firefox crashes upward. If I try to keep typing I have a message "do not answer" and will have to wait until he's going to continue. This always occurs when you browse through my e-mail, but it happens to other sites, whenever I have to type an entry. I have tried disabling all my modules and it still happens. I deleted Firefox and reloaded it and the problem persists. I'm about to go back to Microsoft Explorer, because it is too long to navigate in Firefox. I use Windows 7, 64 bit, on a one-year-old Dell with a lot of speed, laptop memory and hard disk space.
See Firefox crashes
Also, try running Firefox in questions to troubleshoot Firefox in Safe Mode. If it works properly in this configuration, then one of your modules is the culprit.
I also notice a couple of old installations plugin in your system specs. I recommend you to update Flash on v10.2.159.1 which also addresses a recently discovered Zero Day exploit. See Adobe releases Flash Player security update
Update via http://get.adobe.com/flashplayer/Also, go to the Windows Control Panel. Java and updated for v1.6.0_24 by clicking on 'Update Now' button.
You have AVG Safe Search, AVG Linkscanner or McAfee Secure Search installed? All three are problematic and tend to cause Firefox to slow down. They can be disabled in tools | Add - ons | Extensions.
If the problem persists despite the above measures, please let us know and we will try to help you further.

Satellite P300 - 20 H refresh the screen every 10 minutes and turn off during 3 sec
Hey,.
Basically, I bought my P300 Sat about a month previously and each time it runs, battery, the same error will occur...
It will update the screen every 10 minutes or more and turn off for 2-3 seconds.This isn't a big problem, but it is annoying that I can not sort.
I tried to run a check of problem to find a solution, but he says that he can not find a.Help, please
Thank you.Hello!
Can you please explain what you mean with refresh? And what exactly is happening?
It is not easy to say what the reason is for this, but have tested an external monitor on the laptop? And you can determine if it s a problem with the internal display or not.
In addition, you must make sure that you have installed the latest display driver and BIOS. The two you can find on the Toshiba site:
http://EU.computers.Toshiba-Europe.com-online decision-making supported Downloads & => Download driversIf you installed a display driver Toshiba not you should remove it. These display drivers can often cause problems and don t have protection against overheating.
Good bye
