  • Not getting key value from Identity column back after inserting new row with SubSonic ActiveRecord

    - by mikedevenney
    I'm sure I'm missing the obvious answer here, but could use a hand. I'm new to SubSonic and using version 3. I've got myself to the point of being able to query and insert, but I'm stuck with how I would get the value of the identity column back after my insert. I saw another post that mentioned Linq Templates. I'm not using those (at least I don't think I am...?) TIA ... UPDATE ... So I've been debugging through my code watching how the SubSonic code works and I found where the indentity column is being ignored. I use int as the datatype for my ID columns in the database and set them as identity. Since int is a non-nullable data type in c# the logical test in the Add method (public void Add(IDataProvider provider)) that checks if there is a value in the key column by doing a (key==null) could be the issue. The code that gets the new value for the identity field is in the 'true path', since an int can't be null and I use ints as my identity column data types this test will never pass. The ID field for my object has a 0 in it that I didn't put there. I assume it's set during the initialization of the object. Am I off base here? Is the answer to change my data types in the database? Another question (more a curiosity). I noticed that some of the properties in the generated classes are declared with a ? after the datatype. I'm not familiar with this declaration construct... what gives? There are some declared as an int (non key fields) and others that are declared as int? (key fields). Does this have something to do with how they're treated at initialization? Any help is appreciated! --BUMP--

  • Border of single th spreads to neighboring th when colspan set on td row below

    - by Samuel Hapak
    Having following html code: <table> <tr><th>First</th><th class='second'>Second</th><th class='third'>Third</th><th>Fourth</th></tr> <tr><td>Mike</td><td colspan=2 >John</td><td>Paul</td></tr> </table>? And following css: table { border-collapse: collapse; } td, th { border: 1px black solid; } td { border-top: none; } th { border-bottom: none; } th.second { border-bottom: 3px green solid; } th.third { } ? I would expect as result one table with 3px solid green line below the second th cell. Instead of that in Chrome, I have solid green border below both the second and the third th cell. In the firefox, results are just as expected. Is this browser bug, or my code is illegal? You can see example at http://jsfiddle.net/tt6aP/3/ PS: Try to set th.third { border-bottom: 2px solid red; } And then try to raise it to 3px. This is even more strange. Screenshots Expected: Chrome: Firefox:

  • MySQL - how to retrieve columns in same row as the values returned by min/mx

    - by Gala101
    I couldn't frame the Question's title properly.. Suppose a table of weekly movie Earnings as below, MovieName MovieGross WeekofYear Year So how do I get the names of top grossers for each week of this year If I do select MovieName , Max(MovieGross) , WeekofYear from earnings where year = 2010 group by WeekofYear; Then obviously query wont run, select Max(MovieName) , Max(MovieGross) , WeekofYear from earnings where year = 2010 group by WeekofYear; would just give movies starting with lowest alphabet Is using group-concat and then substring-index the only option here? select substring_index(group_concat(MovieName order by MovieGross desc),',',1), Max(MovieGross) , WeekofYear from earnings where year = 2010 group by WeekofYear ; Seems clumsy.. Is there any better way of acieveing this?

  • database row/ record pointers

    - by David
    Hi I don't know the correct words for what I'm trying to find out about and as such having a hard time googling. I want to know whether its possible with databases (technology independent but would be interested to hear whether its possible with Oracle, MySQL and Postgres) to point to specific rows instead of executing my query again. So I might initially execute a query find some rows of interest and then wish to avoid searching for them again by having a list of pointers or some other metadata which indicates the location on a database which I can go to straight away the next time I want those results. I realise there is caching on databases, but I want to keep these "pointers" else where and as such caching doesn't ultimately solve this problem. Is this just an index and I store the index and look up by this? most of my current tables don't have indexes and I don't want the speed decrease that sometimes comes with indexes. So whats the magic term I've been trying to put into google? Cheers

  • Validating using stripes causes bound values to delete

    - by Davoink
    I'm using Stripes and I am validating the values of a drop down box to ensure the user selects an option. On initial load all data is present, but once the validation kicks in the form loses the data that was set up in the action bean on load. This includes the original list I am validating against. I'm simply using in the jsp, and annotating the field in the action bean as @Validate(required=true). Am I missing something simple? Cheers

  • JPA CascadeType.ALL does not delete orphans.

    - by Paul Whelan
    I am having trouble deleting orphan nodes using JPA with the following mapping @OneToMany (cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy = "owner") private List<Bikes> bikes; I am having the issue of the orphaned roles hanging around the database. I can use the @org.hibernate.annotations.Cascade Hibernate specific tag but obviously I don't want to tie my solution into a hibernate implementation. Any pointers greatly appreciated.

  • Testing on blackberry device - adding and removing app multiple times

    - by Kai
    It would be useful for many people to know how to completely remove an application from your device when testing. I have downloaded my app many times now, and likewise have deleted it many times. The problem is when deleting the app, it does not remove things like the persistent object related to my app, or the images downloaded through the app. So, when I download the next build, I have no idea if something broke that is related to building the persistent object or fetching the images since those elements already exist from the last build. I don't know if this is a cache thing. I don't know if this is expected and I have to use some utility to wipe this data after deleting the app. I can't really find much info through basic web searches. Any information would be appreciated. Blackberry Bold 9000. 4.6 OS. tested with both SD card and no SD card.

  • R- delete rows in multiple columns by unique number

    - by Vincent Moriarty
    Given data like this C1<-c(3,-999.000,4,4,5) C2<-c(3,7,3,4,5) C3<-c(5,4,3,6,-999.000) DF<-data.frame(ID=c("A","B","C","D","E"),C1=C1,C2=C2,C3=C3) How do I go about removing the -999.000 data in all of the columns I know this works per column DF2<-DF[!(DF$C1==-999.000 | DF$C2==-999.000 | DF$C3==-999.000),] But I'd like to avoid referencing each column. I am thinking there is an easy way to reference all of the columns in a particular data frame aka: DF3<-DF[!(DF[,]==-999.000),] or DF3<-DF[!(DF[,(2:4)]==-999.000),] but obviously these do not work And out of curiosity, bonus points if you can me why I need that last comma before the ending square bracket as in: ==-999.000),]

    - by Jreeter
    Hey guys I got a weird issue.. I have a datalist that's only loaded on pageload it contains 2 columns a name and date and has 398 rows.. In IE 7 and above(and prob previous version) when I open a modal via a button click it takes almost 5 seconds to open. HOWEVER, if I do not bind this datalist it's MUCH faster.. Also this is only happening in IE, Chrome, Firefox and opera both open the modal instantly with the datalist binded... Josh

  • phpMyAdmin Cron to Delete Temporary Files

    - by JoeC
    I have a folder on my hosting which I periodically upload something to - /public_html/uploads - and I'd like to set up a cronjob through phpMyAdmin to empty it out on a regular basis. The current cron I have in pMA is find /public_html/uploads -maxdepth 1 -ctime 1 -exec rm -f {} \; (Ignore the fact that it's running every minute for now, it's so I can test it :) ) I know very little about what this command is actually doing, but it looks like "not very much". Can anyone help me fix it? :) Thanks.

  • Using Python read specific (column, row) values from a txt file

    - by user2955708
    I would like to read values from a text file until that is a float value. Lets say I have the following file: 14:53:55 Load 300 Speed 200 Distance,m Fz Fx Speed 0.0000 249 4 6.22 0.0002 247 33 16.29 0.0004 246 49 21.02 0.2492 240 115 26.97 0.2494 241 112 21.78 0.2496 240 109 13.09 0.2498 169 79 0.27 Distance,m Fz Fx Speed 0.0000 249 4 7.22 0.0002 247 33 1.29 0.0004 246 49 271.02 0.2492 240 115 26.97 0.2494 241 112 215.78 0.2496 240 109 13.09 0.2498 169 79 0.27 And I need only the values under the first Distance column. So something like skip the first few rows, then read values from the first column while it is float. Thanks your help in advance

  • PHP cookie removal in FireFox 14.0.1

    - by sepoto
    <?php session_start(); $_SESSION['logged_in'] = false; setcookie("dsgpassword127", $password, time()-3600); /* expire the cookie */ setcookie("dsgemail127", $email, time()-3600); /* expire the cookie */ session_destroy(); header("location: index.php"); ?> The code above which works very well in Chrome will not remove the cookies in FireFox 14.0.1. I am wondering why this is, if anyone has experienced the same problem or if there is a solution to this conundrum I am in when it comes to expiring these cookies.... Thank you.

  • Delete an object from a tree

    - by mqpasta
    I have a Find function in order to find an element from a BST private Node Find(ref Node n, int e) { if (n == null) return null; if (n.Element == e) return n; if (e > n.Element) return Find(ref n.Right, e); else return Find(ref n.Left, e); } and I use following code in order to get a node and then set this node to null. Node x = bsTree.Find(1); x = null; bsTree.Print(); supposedly, this node should be deleted from Tree as it is set to null but it still exists in tree. I had done this before but this time missing something and no idea what.

  • ndarray field names for both row and column?

    - by Graham Mitchell
    I'm a computer science teacher trying to create a little gradebook for myself using NumPy. But I think it would make my code easier to write if I could create an ndarray that uses field names for both the rows and columns. Here's what I've got so far: import numpy as np num_stud = 23 num_assign = 2 grades = np.zeros(num_stud, dtype=[('assign 1','i2'), ('assign 2','i2')]) #etc gv = grades.view(dtype='i2').reshape(num_stud,num_assign) So, if my first student gets a 97 on 'assign 1', I can write either of: grades[0]['assign 1'] = 97 gv[0][0] = 97 Also, I can do the following: np.mean( grades['assign 1'] ) # class average for assignment 1 np.sum( gv[0] ) # total points for student 1 This all works. But what I can't figure out how to do is use a student id number to refer to a particular student (assume that two of my students have student ids as shown): grades['123456']['assign 2'] = 95 grades['314159']['assign 2'] = 83 ...or maybe create a second view with the different field names? np.sum( gview2['314159'] ) # total points for the student with the given id I know that I could create a dict mapping student ids to indices, but that seems fragile and crufty, and I'm hoping there's a better way than: id2i = { '123456': 0, '314159': 1 } np.sum( gv[ id2i['314159'] ] ) I'm also willing to re-architect things if there's a cleaner design. I'm new to NumPy, and I haven't written much code yet, so starting over isn't out of the question if I'm Doing It Wrong. I am going to be needing to sum all the assignment points for over a hundred students once a day, as well as run standard deviations and other stats. Plus, I'll be waiting on the results, so I'd like it to run in only a couple of seconds. Thanks in advance for any suggestions.
