  • MySQL friends table

    - by asmo
    I have a MySQL DB in which I store data about each user. I would like to add a list of friends for each user. Should I create a table of friends for each user in the DB or is there a better way?

  • TSQL Writing into a Temporary Table from Dynamic SQL

    - by Jeff
    Consider the following code: SET @SQL1 = 'SELECT * INTO #temp WHERE ...' exec(@SQL1) SELECT * from #temp (this line throws an error that #temp doesn't exist) Apparently this is because the exec command spins off a separate session and #temp is local to that session. I can use a global temporary table ##temp, but then I have to come up with a naming scheme to avoid collisions. What do you all recommend?

  • Modifying LaTeX Table of Contents to add a period after chapter/table/figure number

    - by Reverend Gonzo
    I need to add a period after the chapter/table/figure number in each line in Table of Contents/LoT/LoF. ie, right now it shows: TABLES 1 first 2 second but I need it to show: TABLES 1. first 2. second I know this can be done with the tocloft package, however, that package is conflicting with the latex style I'm using, with the error: \c@lotdepth is already defined. (The style is an old style for my university's thesis format, but it's slightly out of date, so I need to make some changes to get it right. I also found that I can change thechapter/thetable/thefigure, so those contain periods. However, that then messes up my references and has the period in all of my references.

  • Update table.column with another table.column with common joined column

    - by Matt
    Hit a speed bump, trying to update some column values in my table from another table. This is what is supposed to happen when everything works Correct all the city, state entries in tblWADonations by creating an update statement that moves the zip city from the joined city/state zip field to the tblWADonations city state TBL NAME | COLUMN NAMES tblZipcodes with zip,city,State tblWADonations with zip,oldcity,oldstate This is what I have so far: UPDATE tblWADonations SET oldCity = tblZipCodes.city, oldState = tblZipCodes.state FROM tblWADonations INNER JOIN tblZipCodes ON tblWADonations.zip = tblZipCodes.zip Where oldCity <> tblZipcodes.city; There seems to be easy ways to do this online but I am overlooking something. Tried this by hand and in editor this is what it kicks back. Msg 8152, Level 16, State 2, Line 1 String or binary data would be truncated. The statement has been terminated. Please include a sql statement or where I need to make the edit so I can mark this post as a reference in my favorites. Thanks!

  • T-SQL Table Variable Creating PHYSICAL Table!

    - by Mike
    OMG! What am I doing wrong? declare @WTF TABLE ( OrderItemId int ) SELECT TOP 20 OrderItemId as OrderItemId INTO [@WTF] FROM ac_OrderItems SELECT * FROM [@WTF] Problem A: This creates a PHYSICAL table called @WTF. WHY?? I thought this was in memory only?! Problem B: The last line of code, if I do select * from @WTF... WITHOUT the [ ], it returns NOTHING. What is the significance of the [ ]? I need serious help. I'm losing my MIND! Thanks in advance.

  • Core Data table record count

    - by user339633
    I have an entity called Person and it has a relationship called participatingGames, to another entity called GameParticipant. I (apparently) can retrieve the number of matches in the GameParticipant entity using this simple code in the Person object I created from the entity in the model: [self.participatingGames count]; However, I'd just like to retrieve the number of Person records and one might guess the syntax for this is just as simple. I have lots of books including those by Jeff LaMarche, but those sources and what I find around here make me wonder if I need to set up a fetchedResultsController just to know the count of some entity. My background is in SQL, so of course it seems odd that what would take 15 seconds to code in any other environment seems like such a well-guarded secret in Core Data. I'm using iPhone SDK 3.1.4 under OSX 10.5.8 Suggestions?

  • Speeding up inner joins between a large table and a small table

    - by Zaid
    This may be a silly question, but it may shed some light on how joins work internally. Let's say I have a large table L and a small table S (100K rows vs. 100 rows). Would there be any difference in terms of speed between the following two options?: OPTION 1: OPTION 2: --------- --------- SELECT * SELECT * FROM L INNER JOIN S FROM S INNER JOIN L ON L.id = S.id; ON L.id = S.id; Notice that the only difference is the order in which the tables are joined. I realize performance may vary between different SQL languages. If so, how would MySQL compare to Access?

  • MySQL query : all records of one table plus count of another table

    - by Ricardo
    Hello Guys! I have 2 tables: User and Picture. The Picture table has the key of the user. So basically each user can have multiple pictures, and each picture belongs to one user. Now, I am trying to make the following query: I want to select all the user info plus the total number of pictures that he has (even if it's 0). How can I do that? Probably it sounds quite simple, but I am trying and trying and can't seem to find the right query. The only thing I could select is this info, but only for users that have at least 1 picture, meaning that the Pictures table has at least one record for that key... But I also wanna consider the users that don't have any. Any idea? Thanks!

  • Python: NameError: 'self' is not defined

  • Releasing an open source project without getting embarrassed

    - by Hopeful
    I've been working by myself on a fairly large open source project for quite a while and it's nearing the point where I'd like to release it. However, I'm self-taught and I don't really know anyone who could adequately review my project. A few years ago, I had released a small bit of code which pretty much got ripped apart (in a critical sense) on the forum where I released it. Even though the code worked, the criticism was accurate but brutal. It prompted me to begin searching for best practices for everything and in the end I feel that it made me a much better developer. I've gone over everything in my project so many times trying to make it perfect that I've lost count. I believe in my project and think it has the potential to help a lot of people and I feel like I've done some cool things in interesting ways with it. Still, because I'm self-taught, I can't help but wonder what gaps exist in my self-education. The way my code was ripped apart last time isn't something I'd like to repeat. I think my two biggest fears with releasing my project that I've poured countless hours into are being absolutely embarrassed because I missed some patently obvious things because of my self-education or, worse, releasing it to the sound of crickets. Is there anyone who has been in a similar situation? I'm not afraid of constructive criticism, so long as it is constructive and not just a rant on how I screwed up. I know there is a code review site on StackExchange, but it's not really set up for large projects and I didn't feel like the community there is large enough yet to get good feedback if I were to post parts of my project piecemeal (I tried with one file). What can I do to give my project at least some measure of success without getting embarrassed or devestated in the process?

  • Adjust CSS of all cells of a specific table without giving each cell a unique id?

    - by javanix
    Is there any way to modify the CSS properties of one table's cells based on the table's ids, rather than specific child ids? I would like to change one table's appearance (giving each cell a colored border, for instance) one way, and another table another way, but I'd like to avoid specifying an id for each cell. To be clear, I don't need to individually access each cell in the table - I just want to set all of the properties of "child" cells of various tables.

  • Self-hosting vs. Budget hosting - What are the economics?

    - by cdonner
    My current hosting provider (shared Linux, unlimited domains, < $10 per month, with about 20 sites) has been giving me a lot of grief lately. I am contemplating to just ditch them and repurpose the old Sun V20z that is sitting in my basement rack, and move the hosting in-house, literally. My math goes as follows: my company pays up to $80 a months for my home internet service, which would cover the upgrade from currently Fios to Comcast business internet with 5 static IPs. So this comes free. running the server will cost me about $180/year at the current rate of approx. $.2/kWh my time is free So, it seems that the my net cost of doing this would be about $80 anually, plus the work that goes into setup and maintenance. I will have to get email hosting somewhere, which I do not want to do myself. On the other side of the balance sheet, I'd likely get better uptime than my provider based on recent stats, will not get suspended and don't have to spend hours with customer support. Overall, I am not convinced. Has anybody actually done that? What was your experience, and did it pay off?

  • Un-table a cell range in Excel 2007

    - by Joe
    In Excel 2007, if you highlight a block of cells and then "Format as Table", it doesn't just apply colors and formatting, it somehow marks those cells as being a table. Now I want to get rid of the table, but keep all the cells (i.e. keep the data). So I tried clearing the table style and formatting, but Excel still recognizes those cells as being a table. I can tell because: When I select a cell that was in the table, Excel still displays the "Table Tools / Design" tab I cannot merge cells that were in the table <- this is what's annoying me So, how do I un-table those cells? I want to keep all the cell data and formatting, but have Excel not recognize them as a table.

  • Collabnet Subversion and Self Signed Certificates

    - by Robert May
    We installed Collabnet as our subversion server recently.  This is the first time that we’ve used it.  In general, it seems pretty good, but we ran into a problem with it.  People were getting the following error in Tortoise: OPTIONS of ’https://xxxx.xxxxxxxx.xxxx/svn/xxxxx’: SSL handshake failed: SSL error code – 1/1/336032856 (https://xxxx.xxxxxxxx.xxxx) The odd thing is that for some people, it worked, for others, it didn’t!  I also couldn’t find anything useful out on the internet. We had checked the Subversion Server should serve via https option in the settings, and all of the ports were open, etc. This option causes a self signed certificate to be used. What we discovered: Tortoise must use the same url as is in the Hostname field on the General settings for collabnet or you’ll get this error.  Basically, some people were using https://svn.xxxxxxx.xxxxx and others were using https://computername.xxxxxxxx.xxxx.  Because the host name said used the computer name version, the whole thing broke.  By changing the host name to the svn version, which is what they should be using, the problem went away.  The users do get the “Accept Certificate” prompt, but we can live with that!

  • How can I use domain masking without having self referral in Google Analytics

    - by Cdore
    I have one old domain that points to a website's server's ip (let's call it www.oldsite.com). I have a new one, www.newsite.com, that is set up to be forwarded to a specific page on the website. Due to the way the host of newsite.com places the website in a frame, in Google Analystics, the newsite.com is listed as a source rather than the source they were at before hand, causing a self referral. A solution is to edit the code of the iframe as I looked up, but there's no way to really edit the host's masking source code of course. Another solution I did previously was have www.newsite.com point to the address that www.oldsite.come pointed to. It solved the analytics problems, but in exchange, the url masking no longer worked. In the address bar, it came up as www.oldsite.com. Is there a way to make me have url masking and be able to forward to agree with google analytics? The server of the website is hosted on a cloud server, if this is anymore information.

  • Self-imposed lockout from program

    - by Alex
    I'm plagued with a lack of willpower. I recently started looking for solutions, and came across a program for macs called SelfControl which completely blocks one's access to a given set of websites for a given period of time (you can delete the program/restart your computer/do almost anything and it will still block those sites for the specified time period, and doesn't require a password to do it.) Unfortunately, there are no windows analogues. The one that comes the closest is Cold Turkey. It has the functionality whereby you set a time in the future, specify a list of websites (or programs - eg explorer, firefox, chrome) and you are blocked from accessing them for the whole duration. No password can undo it, no system reboot, etc. The problem is that the program is a buggy piece of garbage, and in order to ensure that you're not locked out from websites forever, you have to run an uninstaller which is just an exe file accessible at any time which completely defeats the purpose of a self-imposed program lockout. I want to make a better version of that program, or find a simple way to prevent access to a given set of programs over a given period of time with no way around it. I've only taken a few introductory courses in java (math major), but the internet is really having a negative effect on my studies, and the only way I can do work is to eliminate all distractions. What do I need to learn in order to make a program with the following properties: Given a set of .exe files, and a time in the future , this program will prevent access to the given .exe files until current time = given time restarting the computer doesn't interfere with the program, one can't uninstall the program until current time = given time, one can't create another instance of the program to block itself I don't care how much programming knowledge i need to acquire in order to make this program, so please give me a specific list of things that I need to study in order to make this happen, or if something like this exists, then please let me know.

  • Single Table Per Class Hierarchy with an abstract superclass using Hibernate Annotations

    - by Andy Hull
    I have a simple class hierarchy, similar to the following: @Entity @Table(name="animal") @Inheritance(strategy=InheritanceType.SINGLE_TABLE) @DiscriminatorColumn(name="animal_type", discriminatorType=DiscriminatorType.STRING) public abstract class Animal { } @Entity @DiscriminatorValue("cat") public class Cat extends Animal { } @Entity @DiscriminatorValue("dog") public class Dog extends Animal { } When I query "from Animal" I get this exception: "org.hibernate.InstantiationException: Cannot instantiate abstract class or interface: Animal" If I make Animal concrete, and add a dummy discriminator... such as @DiscriminatorValue("animal")... my query returns my cats and dogs as instances of Animals. I remember this being trivial with HBM based mappings but I think I'm missing something when using annotations. Can anyone help? Thanks!

  • Rails single table inheritance/subclass find condition in parent

    - by slythic
    Hi all, I have a table called Users (class User < ActiveRecord::Base) and a subclass/STI of it for Clients (class Client < User). Client "filtering" works as expected, in other words Client.find(:all) works to find all the clients. However, for users I need to filter the result to only find users that are NOT clients (where type is null or blank). I've tried the following in my index controller but no matter what I put for the type it returns all users regardless of type. User.find(:all, :conditions => { :type => nil }, :order => 'name') Any clue on how to get this condition to work? Thanks!
