  • SQL SELECT using in() but excluding others.

    - by Pickledegg
    I have a table called 'countries' linked to another table 'networks' with a many to many relationship: countries countries_networks networks +-------------+----------+ +-------------+----------+ +-------------+---------------+ | Field | Type | | Field | Type | | Field | Type | +-------------+----------+ +-------------+----------+ +-------------+---------------+ | id | int(11) | | id | int(11) | | id | int(11) | | countryName | char(35) | | country_id | int(11) | | name | varchar(100) | +-------------+----------+ | network_id | int(11) | | description | varchar(255) | To retrieve all countries that have a network_id of 6 & 7, I just do the following: ( I could go further to use the networks.name but I know the countries_networks.network_id so i just use those to reduce SQL.) SELECT DISTINCT countryName FROM countries AS Country INNER JOIN countries_networks AS n ON Country.id = n.country_id WHERE n.network_id IN (6,7) This is fine, but I then want to retrieve the countries with a network_id of JUST 8, and no others. I'ver tried the following but its still returning networks with 6 & 7 in. Is it something to do with my JOIN? SELECT DISTINCT countryName FROM countries AS Country INNER JOIN countries_networks AS n ON Country.id = n.country_id WHERE n.network_id IN (8) AND n.network_id not IN(6,7) Thanks.

  • Netbook won't boot after using EasyBCD

    - by TNC
    I have an Asus T91MT netbook on which I used to have Windows 7 Home Premium and Ubuntu 10.10 installed (dual boot). After trying to upgrade to Ubuntu 11.04, Ubuntu is no longer able to boot, so I tried to uninstall Ubuntu completely and then reinstall it. Following these directions, I tried using EasyBCD to bypass the GRUB2 bootloader so that after uninstalling, it would automatically boot into Windows 7. However, after doing the "install BCD" step and restarting, I got the following message: Windows failed to start... File: \Boot\BCD; Status: 0xc0000098; Info: The Windows Boot Configuration Data file does not contain a valid OS entry. I'm currently trying to create a USB stick of the Windows Installation disc but in the mean time, I can only boot from a Ubuntu USB stick. Is there anything I can do from within Ubuntu to fix this? Or does anyone have any other suggestions/solutions?

  • How to connect to VPN using commands in Linux (Fedora 16)

    - by WarFox
    Usually, I use the network connections icon on the top bar to connect to VPN. The connection is configured properly and it connects well. Configuration screen shot is given below. As you can see I have selected the 'Connect automatically' option. But this option doesn't help in connecting to VPN automatically upon login. This is my university VPN and it uses 'Point-to-Point encryption (MPPE)' for authentication I need to connect to the VPN using command line, so that I can write a script and run it at start up, so the connection is automatically established every time I login. This will also help in connecting to VPN when I login from 'init 3' mode. I depend on this VPN connection for my internet access. Please help me with the required commands.

  • How to optimize indexing of large number of DB records using Zend_Lucene and Zend_Paginator

    - by jdichev
    So I have this cron script that is deployed and ran using Cron on a host and indexes all the records in a database table - the index is later used both for the front end of the site and the backed operations as well. After the operation, the index is about 3-4 MB. The problem is it takes a lot of resources (CPU: 30+ and a good chunk of memory) and slows the machine down. My question is about how to optimize the operation described below: First there is a select query built using the Zend Framework API, this query is then passed to a Paginator factory that returns a paginator which I am using to balance the current number of items being indexed and not iterate over too much items. The script is iterating over the current items in the paginator object using a foreach loop until reaching the end and then it starts from the beginning after getting items for the next page. I am suspecting this overhead is caused by the Zend_Lucene but no idea how this could be improved.

  • PHP - Problem using file_get_contents

    - by shyam
    I have a problem while using the file_get_contents function. I am using it to get a response from a different web server, but it's not returning anything (shown as empty string using var_dump). Also, the problem is only while calling this specific server, because I got result when I used Google's address; and it's working fine in my local machine. I've tried cUrl too - but same result.

  • How to save to two tables using one SQLAlchemy model

    - by Oatman
    I have an SQLAlchemy ORM class, linked to MySQL, which works great at saving the data I need down to the underlying table. However, I would like to also save the identical data to a second archive table. Here's some psudocode to try and explain what I mean my_data = Data() #An ORM Class my_data.name = "foo" #This saves just to the 'data' table session.add(my_data) #This will save it to the identical 'backup_data' table my_data_archive = my_data my_data_archive.__tablename__ = 'backup_data' session.add(my_data_archive) #And commits them both session.commit() Just a heads up, I am not interested in mapping a class to a JOIN, as in: http://www.sqlalchemy.org/docs/05/mappers.html#mapping-a-class-against-multiple-tables

  • Access denied for user 'root@localhost' (using password:NO)

    - by murgatroid99
    I am attempting to install a network management package called cacti onto Ubuntu running under Windows Virtual PC. I attempted to install MySQL as it is one of cacti's dependencies. I can install and start the MySQL server, but whenever I try to access it in any other way, such as to change the password, I get the error message Access denied for user 'root@localhost' (using password:NO). I would like to know what is causing this and how to fix it. Edit: (just in case my comments are not visible) The answers from HD and Devin Ceartas did not work for me.

  • Difference in declaring IDisposable member in using block or at using block declaration?

    - by dotnetdev
    Hi, I have the code below: using (SqlCommand command = new SqlCommand()) { command.CommandType = System.Data.CommandType.StoredProcedure; command.Connection = new SqlConnection(); command.CommandText = ""; command.Parameters.Add(new SqlParameter("@ExperienceLevel", 3).Direction = System.Data.ParameterDirection.Input); SqlDataReader dataReader = command.ExecuteReader(); } Is there any functional impact in declaring the SqlConnection where I currently am declaring it as opposed to like so?: using (SqlCommand command = new SqlCommand()) using (SqlConnection connection = new SqlConnection()) Thanks

  • Print numbers sequentially using printf with filling zeroes

    - by Werner
    Hi, in C++, using printf I want to print a sequence of number, so I get, from a "for" loop; 1 2 ... 9 10 11 and I create files from those numbers. But when I list them using "ls" I get 10 11 1 2 .. so instead of trying to solve the problem using bash, I wonder how could I print; 0001 0002 ... 0009 0010 0011 and so on Thanks

  • using generic and for each loop in jsp

    - by mawia
    I am developing a web application. I am using Eclipse as IDE. I was using generic and for each loop, both being feature of java 1.5, and it compiled quite fine when used in backend means in simple java classes. But when I'm using these on jsp, jsp is failing to compile with error showing generic and for each as culprit. Can you shed some light on this? Maybe I am at fault with Eclipse settings?

  • Excel VLOOKUP using results from a formula as the lookup value [on hold]

    - by Rick Deemer
    I have a cell that I must remove the first 2 characters "RO" for each value in a column on a sheet called RAW DATA and put into a cell on a sheet called ROSS DATA. Some of the values in that cell have 3 digits after the "RO", and some have 5 digits. To do that I used =REPLACE('RAW DATA'!A3,1,2,"") Then I need to use this new resultant string as the lookup value in a VLOOKUP. The VLOOKUP will be looking at a named range called DAP on a sheet called DAP, in column 5 for an exact match, and I need it to return that value to the cell. I have tried using INDIRECT in different ways to no avail, and I'm not sure that I fully understand its usage. So at this point I am Googling for a method to do this and at a standstill.

  • Google document does not print correctly on Mac 10.7.5 using Chrome

    - by Android Addict
    When attempting to print a Google document, the header does not get printed at all and the text starts almost in the center of the page - cutting off almost half of the text in the printable area horizontally. The vertical alignment appears fine, with the exception of hte missing header. I have searched the product forums at Google, but they are virtually unusable. Endless threads without a solution! For reference, the document prints fine from Windows XP using Chrome. I can also print from other applications on the Mac without issue - so I am thinking it's a Google doc issue at this point.

  • I Cannot connect to remote MySQL database using SSH tunnel

    - by Scott
    Brand new server, brand new MySQL 5.5 install on Ubuntu 12.04. I can log in to the database as root from the command line. I can log on via Navicat MySQL or Sequel Pro as root on port 3306 from my Mac. I cannot log in using an SSH tunnel to the server and then to the database as root. I have tried both localhost and 127.0.0.1 as server for the local connection part. My password is fine. root is currently defined at %, 127.0.0.1, and localhost. I have set up this same type of connection at least 30 times before and never had a problem. The SSH connection gets made with no problem, and then it just hangs trying to connect to the DB and finally times out. The only thing I changed in my.cnf was to comment out the bind-address = 127.0.0.1 line. Any help? Any Ideas?

  • Accessing Arbitrary Columns from an R Data Frame using with()

    - by johnmyleswhite
    Suppose that I have a data frame with a column whose name is stored in a variable. Accessing this column using the variable is easy using bracket notation: df <- data.frame(A = rep(1, 10), B = rep(2, 10)) column.name <- 'B' df[,column.name] But it is not obvious how to access an arbitrary column using a call to with(). The naive approach with(df, column.name) effectively evaluates column.name in the caller's environment. How can I delay evaluation sufficiently that with() will provide the same results that brackets give?

  • Search desktop files using a list of keywords stored in a text file

    - by Tod1d
    I have a list of 1285 keywords (database object names) that I have compiled into a TXT file; one keyword per line. I would like to search a directory of files (most have a .aspx or .cs extension) using this list of keywords. My main goal is find out which of the 1285 database objects are being referenced in these files. Can anyone recommend a tool that could accomplish this? Otherwise, I will just create my own. Thanks.
