• SQL Server: Find Values that don't exist in a table

  - by MacAnthony

  I have a list or set of values that I would like to know which ones do not currently exist in a table. I know I can find out which ones do exist with: SELECT * FROM Table WHERE column1 IN (x,x,x,x,x) The set is the values I am checking against. Is there a way to find out which values in that set do not exist in column1? Basically, I'm looking for the inverse of the sql statement above. This is for a report, so all I need is the values that don't exist to be returned back. I have and could do this with a left join and putting the values in another table, but the values I check are always different and was hoping to find a solution that didn't involve clearing a table and inserting data first. Trying to find a better solution for me if one exists.

• How to find where error is.

  - by gurugio

  How can I find where the error occurs? In C language, the return value means what error occurs, such as failure to open file or memory allocation. There is no information where the error occurs. For example, function 'foo' calls A,B,C,D. If foo returns an error value, it might be return value of A or B or C or D. I cannot find what function returns error. I have to run debugger or add some codes to find what function returns error.

I have read after installation the libs gets extracted to /data/data/application_package/lib How can I get the exact path to this directory in my application at run time?

• PostSharp deployment to build machine- use Setup installation, not NuGet package.

  - by Michael Freidgeim

  PostSharp has well documented different methods of installation. I've chosen installing NuGet packages, because according to  Deploying PostSharp into a Source Repository NuGet is the easiest way to add PostSharp to a project without installing the product on every machine. However it didn't work well for me. I've added PostSharp NuGet package to one project in the solution.  When I wanted to use PostSharp in other project, Visual Studio tab showed that PostSharp is not enabled for this project I've added the NuGet package to the new project, which installed a new version of the package in the new Packages subfolder. When I wanted to refer PostSharp from the third project, I've ended up with another version of PostSharp installed. Additionally multiple versions of Diagnostics were created. It definitely causes confusion and errors.   More problems we experienced on build server. According to Using PostSharp on a Build Server "If you chose to deploy PostSharp in the source repository, it does not need to be installed specifically on the build server. " It didn't work on our build server. I kept getting errors "The "AddIns" parameter is not supported by the "PostSharp21" task." and "The "DisableSystemBindingPolicies" parameter is not supported by the "PostSharp21" task."   From my experience the only way to have the latest version of PostSharp working on the build server is to install it using Setup as described in Deploying PostSharp with the Setup Program     Gael acknowledged the issues with possible version conflicts. see http://support.sharpcrafters.com/discussions/problems/388-the-postsharp21-task-failed-unexpectedly

• How do I capture a 10053 trace for a SQL statement called in a PL/SQL package?

  - by Maria Colgan

  Traditionally if you wanted to capture an Optimizer trace (10053) for a SQL statement you would issue an alter session command to switch on a 10053 trace for that entire session, and then issue the SQL statement you wanted to capture the trace for. Once the statement completed you would exit the session to disable the trace. You would then look in the USER_DUMP_DEST directory for the trace file. But what if the SQL statement you were interested  in was actually called as part of a PL/SQL package? Oracle Database 11g, introduced a new diagnostic events infrastructure, which greatly simplifies the task of generating a 10053 trace for a specific SQL statement in a PL/SQL package. All you will need to know is the SQL_ID for the statement you are interested in. Instead of turning on the trace event for the entire session you can now switch it on for a specific SQL ID. Oracle will then capture a 10053 trace for the corresponding SQL statement when it is issued in that session. Remember the SQL statement still has to be hard parsed for the 10053 trace to be generated.  Let's begin our example by creating a PL/SQL package called 'cal_total_sales'. The SQL statement we are interested in is the same as the one in our original example, SELECT SUM(AMOUNT_SOLD) FROM SALES WHERE CUST_ID = :B1. We need to know the SQL_ID of this SQL statement to set up the trace, and we can find in V$SQL. We now have everything we need to generate the trace. Finally  you would look in the USER_DUMP_DEST directory for the trace file with the name you specified. Maria Colgan+

• What do I need to learn to decide on rename/recompile source package names because of company rebranding?

  - by Roberto Linares

  My company is currently at a rebranding process and the brand names have been used in the sources' package names but these names are only visible to developers who maintain this code so nobody from project management is really interested in changing them considering also that it would imply the recompiling of several old components. What factors do I need to consider when deciding on a change like that? I don't know if I should worry about legal issues or not and if so, how to address this with project management. More background details. I have all the sources and dependencies but since the company rebranding, other development areas have adopted some of the code that needs package name-changing so I cannot take the decision only by myself so I don't make everyone else's code to crash with my core components and I cannot change other areas' code without the permission of those areas' users so yes, my concern is more political than technical. I am going try to coordinate the involved it areas to make the change anyway, since it seems to be the best approach.   Unfortunatelly in my company there's no continuous integration build server so we build our code manually on demand and to get something to production I have to justify the change (even just the package name changing) to QA with an user requirement and some other bureaucratic documentation so that's why I was hesitating the change in first place.

• virtualbox installing iso Error "could not find a valid v7 on sda"

  - by MountainX

  I decided to try this suggestion to install Android x86 on Virtual Box. I'm following those steps and I'm at #4. I used the android-x86-4.0-RC1-amd_brazos.iso (because I have a ThinkPad that this might be compatible with and it seemed as good as any of the other choices...) I'm getting an endless series of errors: .[numbers] VFS: could not find a valid v7 on sda. .[numbers] VFS: could not find a valid v7 on sda. repeating... For storage, I made a VDI image sized at 4.0 GB (dynamically allocated) attached on SATA Port 0. Background and more details: I'm running Kubuntu 12.04. I installed VirtualBox 4.1.12 after adding deb http://download.virtualbox.org/virtualbox/debian precise contrib to my sources. EDIT: Now I'm wondering if I installed the right package. I verified that I'm running 4.1.12. But I installed it with apt-get install virtualbox instead of the recommended apt-get install virtualbox-4.1. I checked just now and see this: apt-cache search virtualbox virtualbox - x86 virtualization solution - base binaries virtualbox-4.1 - Oracle VM VirtualBox But when I run VirtualBox, I get the Oracle VM VirtualBox Manager version 4.1.12, so I think I'm OK. I did see one minor issue (possibly related to this question) when installing VB, but in my case I don't think it is actually an error at all: * No suitable module for running kernel found [fail] invoke-rc.d: initscript virtualbox, action "restart" failed. VirtualBox installed and seems to be running fine. I just can't get the ISO image to install. The error is as shown above.

• SChannel "cannot find certificate in either LocalMachine or CurrentUser store"

  - by Chris J

  We have an in-house application that requires the use of client SSL certificates to authenticate with a remote server (not under our control). This has worked without problems before but on deploying to a new server, we're having problems getting Windows 2008 to use the certificate. The certificate exists as a .pfx file that contains a private key. The same certificate exists in the LocalMachine store, again with its private key. We've ensured the one in the LocalMachine store is correct by creating a website in IIS against that certificate, so we're happy that the certificate, certificate chain, and private key is valid. The PFX has been created by exporting from the Certificates MMC snap-in. The issue is that we get the following in the system diagnostic logs that suggests it can't find the private key: System.Net Information: 0 : [5988] SecureChannel#23264094 – Locating the private key for the certificate: [Subject] CN=internal-server.company.com, OU=Servers, OU=Devices, O=org [Issuer] CN=SubCA02, OU=CA, o=org [Serial Number] 407ABCDE [Not Before] 31/10/2013 11:08:48 AM [Not After] 31/10/2016 11:08:48 AM [Thumbprint] 4354A34F6004F019E60F055979A47E50F62D1504 . System.Net Information: 0 : [5988] SecureChannel#23264094 – Cannot find the certificate in either the LocalMachine store or the CurrentUser store. I've validated the thumbprint, issuer and serial number listed in the log with the certificate in the LocalMachine store and these marry up. From what I can tell with much searching, this appears to be a permissions issue. The user the application is running as has been granted access to the private key (Personal Certificates - right click on the certificate - all tasks - Manage Private Keys), so I'm now at a loss as to which permission(s) it may be that is causing the issue.

• Can't find standalone Chrome Gmail client that I know exists

  - by Carson

  I'm on Windows. A couple years ago when I switched from Outlook to Gmail (Google Apps), Google provided this awesome little standalone gmail client that was just a single-purpose Chrome install. It launched like a normal application, stayed updated when I updated Chrome. It was Chrome in a separate application that launched only gmail, stayed logged in really well, and "felt" like a gmail mail client, with the gmail interface. It had it's own little red envelope icon, it was a windows app. (I remember there was no Mac equivalent.) I found it while looking through the "this is how you get your company to switch to gmail" documentation that Google provided. I just repaved my box and now I'm looking for this thing again, and I had no idea it would be impossible to find. I've spent literally 2 hours looking, searching, googling, etc. I'm losing my mind. Anyone know how I can get my hands on this? I used it all day every day for 2 years, so I know it exists :), but I can not find it. Any assistance would be gratefully received.

• Can't find disk usage in one directory

• SQL 2000 Backup/Export Process - Can't find SQL 2000 Enterprise Manager, Can't use Mgmt Studio Expre

  - by 1nsane

  I need to make a backup of a client's SQL 2000 database, however there are a few issues preventing me from doing so using the traditional methods. I've tried using SQL Management Studio Express, but the host doesn't give sufficient privileges to create a backup and I'm getting some strange error messages. I've also tried doing the "Generate Scripts" to recreate the schema, then using the DTS Wizard to migrate the data, but the IDs set up with the identity specification property are not consistent with the live database once copied over. This results in some foreign key breakage... If I remember correctly, I was able to use Microsoft SQL 2000 Enterprise Manager to perform the task before, but I can't find this anywhere... it seems Microsoft has pulled most SQL Server 2000 stuff from their site. Does anyone know where I can find a copy of Enterprise Manager (or a trial of SQL Server 2000, which I believe comes with the component)? Or conversely, does anyone know of any other tools (preferably non-commercial) that are capable of mirroring remote SQL Server 2000 DBs? Thanks!

• "Windows cannot find" file when opening Excel spreadsheet

  - by DanH

  For all of my Excel spreadsheets when I attempt to open them (by double-clicking in explorer) I get the message "Windows cannot find C:...". The files are there, and are valid zip files as seen by 7-Zip. There are no apparent lock files in the directories. I did just install Norton-360 over the weekend (replacing Kasperski), but the Norton log shows no events related to Excel. However, while installing Norton I did reboot with some Excel files open. Presumably something is hosed in my Excel configuration but I don't know what. Update (Before actually posting) -- I found an article that suggested turning off Advanced Option "Ignore other applications that use DDE", then doing excel.exe /unregister followed by excel.exe /register. I tried this but I suspect that the two Excel calls were ignored (Excel opened, but no obvious change). With that option off the spreadsheets load OK, but not with it on. And, curiously, spreadsheets load OK with the option on or off if I open Excel first and then open the spreadsheet in it. Does anyone have any idea what effect leaving that option off will have? Update 2 -- I tried running the "repair" option. It said it corrected a couple of config things (without saying what they were), but I still get a failure if I double-click an Excel file with the "Ignore other applications..." option checked. Update 3 -- I managed to fix this problem, but failed at the time to come back and say what I did, and now I can't remember for sure. But I think it had something to do with "Options"/"Save" and some of the values there. Something to do with AutoRecover, perhaps. (Possibly there was a file in recovery and I had to specify "Disable AutoRecover for this workbook" to let bring-up get past it. Or perhaps the AutoRecover file location was hosed.) Anyway, if it happens to someone else, and you find the fix, post it below and I'll mark it answered.

• Find out the type of an automounted device

  - by Steve Bennett

  I'm working on a system (Ubuntu Precise) with a mount defined in /etc/fstab as follows: /dev/vdb /mnt auto defaults,nobootwait,comment=cloudconfig 0 2 Originally I just wanted to find out if it's NFS (due to potential MySQL locking issues). Judging from man mount, it's not: If no -t option is given, or if the auto type is specified, mount will try to guess the desired type. Mount uses the blkid library for guessing the filesystem type; if that does not turn up anything that looks familiar, mount will try to read the file /etc/filesystems, or, if that does not exist, /proc/filesystems. All of the filesystem types listed there will be tried, except for those that are labeled "nodev" (e.g., devpts, proc and nfs). If /etc/filesystems ends in a line with a single * only, mount will read /proc/filesystems afterwards. But, out of curiosity now, how can I find out more about what type of device it actually is? (For context, this is a VM running on OpenStack. The device is a 60Gb allocation mounted from somewhere - but I don't know how.)` EDIT Including answers here: $ mount /dev/vdb on /mnt type ext3 (rw,_netdev) $ df -T /dev/vdb ext3 61927420 2936068 55845624 5% /mnt

• Exchange 2010 POP3/IMAP4/Transport services complaining that they can't find SSL certificate after blue screen

  We have a single-server Exchange 2010 setup. In the early hours of this morning the server had a blue screen and rebooted. After coming back up the POP3/IMAP4 and Transport services are complaining that they cannot find the correct SSL certificate for mail.example.com.

Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key. The odd part is that Get-ExchangeCertificate show the cert as enabled for all the relevant services, and OWA is working flawlessly using this certificate.

• How do I find funny pictures?

  - by Hanno Fietz

  No, not lolcats. And I'm not really looking for a specific site, either. I have often wished that I had some funny picture to illustrate a presentation, a website, a post, an email, or something else. Google image search and stock photo services have hardly ever helped me, although that may be because I'm doing something wrong. Jeff Atwood seems to have no problem to find funny pictures for his codinghorror and stackoverflow blogs, as well as for the error messages on the trilogy sites. One of my favourites was this elephant. Other bloggers also seem to be quite good at it. I'm wondering if I simply lack the creativity or if there's sources or methods I don't know about. I could think of the following ways to get pictures, but I'm not sure whether this is really "how they do it". keep a collection of pictures that you stumbled upon and liked (takes quite some time to build up to a proper library), when you need a picture, there's one in there maybe have pictures on paper, too, like from magazines or ads. when you are looking for a picture, search online (Flickr, Google, stock photos). This has never really worked for me, I don't know why. produce the pictures yourself, i. e. have a good library of source material or find some online and apply some creativity and suitable software. I could imagine that this could work well once you have the practice.

• uWSGI cannot find "application" using Flask and Virtualenv

  - by skyler

  Using uWSGI to serve a simple wsgi app, (a simple "Hello, World") my configuration works, but when I try to run a Flask app, I get this in uWSGI's error logs: current working directory: /opt/python-env/coefficient/lib/python2.6/site-packages writing pidfile to /var/run/uwsgi.pid detected binary path: /opt/uwsgi/uwsgi setuid() to 497 your memory page size is 4096 bytes detected max file descriptor number: 1024 lock engine: pthread robust mutexes uwsgi socket 0 bound to TCP address 127.0.0.1:3031 fd 3 Python version: 2.6.6 (r266:84292, Jun 18 2012, 14:18:47) [GCC 4.4.6 20110731 (Red Hat 4.4.6-3)] Set PythonHome to /opt/python-env/coefficient/ *** Python threads support is disabled.

Before I added my Virtualenv's pythonpath to my configuration file, I was getting an ImportError for Flask. I solved this though, I believe (I'm not receiving errors about it anymore) and here is my complete configuration file: uwsgi: #socket: /tmp/uwsgi.sock socket: 127.0.0.1:3031 daemonize: /var/log/uwsgi.log pidfile: /var/run/uwsgi.pid master: true vacuum: true #wsgi-file: /var/www/coefficient/coefficient.py wsgi-file: /var/www/coefficient/flask.py processes: 1 virtualenv: /opt/python-env/coefficient/ pythonpath: /opt/python-env/coefficient/lib/python2.6/site-packages This is how I start uWSGI, from an rc script: /opt/uwsgi/uwsgi --yaml /etc/uwsgi/conf.yaml --uid uwsgi And if I try to view the Flask program in a browser, I get this: **uWSGI Error** Python application not found Any help is appreciated.

• In Fedora, Perl program cannot find Time::Piece library

  - by Eric Leschinski

  I have a Perl program named /usr/bin/octbatch running as a script on Fedora 17 Linux. When I run this command: /usr/bin/octbatch I get the error: Can't locate Time/Piece.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at /usr/bin/octbatch line 6. BEGIN failed--compilation aborted at /usr/bin/octbatch line 6. Here is the relevant lines of the Perl script: #!/usr/bin/perl -wT $ENV{PATH} = "/bin:/usr/bin:/usr/local/bin"; use strict; use POSIX qw(setsid :sys_wait_h); use Time::Piece; use Time::Local; I have to install Piece.pm so perl can find it. I've already installed it with this command (using the defaults): /usr/bin/perl -MCPAN -e install Time::Piece I have the Piece.pm file in /home/el/perl5/lib/perl5/x86_64-linux-thread-multi/ however when I run the octbatch command I get the same error as above. Like it can't even find it. Here is my PERL5LIB variable: el@defiant ~/gnuoctbluehost/single_stock_analysis $ env | grep PERL5 PERL5LIB=/home/el/perl5/lib/perl5/x86_64-linux-thread-multi:/home/el/perl5/lib/perl5 And the Piece.pm is located under /home/el/perl5/lib/perl5/x86_64-linux-thread-multi So my question is, Why is it not finding my Piece.pm file? And what are the ways I can get the @INC variable to include it. Or how do I make perl see it?
