• google app engine db.Model in python only display user-defined fields

  - by MattM

  I'm a python newbie so I apologize in advance if this question has been asked before. I am building out an application in GAE and need to generate a report that contains the values for a user-defined subset of fields. For example, in my db model, CrashReport, I have the following fields: entry_type entry_date instance_id build_id crash_text machine_info I present a user with the above list as a checkbox group from which they select. Whichever fields the user selects, I then create a report showing all the values in the datastore, but only for the fields that they selected. For example, if from the above list, the user selects the build_id and crash_text fields, the output might look like this: build_id crash_text 0.8.2 blown gasket 0.8.2 boom! 0.8.1 crack! ... So the question is, how exactly do I only access the values for the fields which the user has defined?

• SSIS Migration - Pulling IDs from dest DB?

  - by TheSciz

  So I'm working on migrating some data to a new server. In the new server, each entry in the MAIN table is assigned a new GUID when the transfer takes place. A few other tables must be migrated, and their records must link to the GUID in the MAIN table. Example... WorksheetID --- GUID 1245677903 --- 1 AccidentID --- WorksheetID --- Guid 12121412 --- 1245677903 --- 1 The guid is used moreso for versioning purposes, but my question is this. In SSIS, is there any way to pull the Worksheet's GUID from the destination database and assign it directly to the entries in the 'Accident' table? Or do I have to just dump the data into the source DB and run some scripts to get everything nicely referenced? Any help would be greatly appreciated.

• Query Mongo Db and filter by associative array key

  - by Failpunk

  How can I search for results in Mongo DB documents using an associative array key. Something like: SELECT * FROM table WHERE keyword like '%searchterm%'; Here is the basic document structure [id] => 31605 [keywords] => Array ( [keyword1] => Array ( [name] => KeyWord1 ) [keyword2] => Array ( [name] => KeyWord2 ) ... ) I would like to do a search within the keywords array on the associative array key [keyword1, keyword2]. The issue is that the name key holds the case-sensitive version of the keyword and the array key is the lower-case keyword name. I could store the lowercase keyword twice, but that seems silly.

• Microsoft Access DB Connection

  - by sikas

  I have a Microsoft Access DB (2003) that I want to connect to it using C# .. The problem I'm facing is I don't have Access installed within the office package .. So I was wondering if it is possible to connect to it as a database to retrieve and update the tables .. Thanks.

When I tried to open SQL Mgmt Studio as Run as administrator than I can able to access database properly. Any idea why it is giving error. I am also getting following error when my asp.net application is trying to access database. Cannot open database "DBName" requested by the login. The login failed.

• Access DB with SQL Server Front End

  - by uyuni99

  I have an old Access application that has a lot of code in forms and reports. The database is getting too large and I am thinking of moving the back end to SQL Server. My requirements are as follows: The DB needs to be multiuser and the users (3-5) will need to log in over the web I would prefer not to re-write the forms and reports in ASP or some other web front end. When I think about my choices, I see them as: Have an Access ADP front end and allows remote log-in to the server where it is stored. Not sure if it is possible for 2 users to simultaneously log in Distribute an ADP front end to the users, but I am not sure if it is possible to connect to a SQL Server back end over the internet, and the network traffic may be an issue. Any other solution? I appreciate all help. u

• Changing CCK content-types details results in numerous DB calls for the menu system

  - by Paul Strugger

  Every time I make a change in the details of a content-type it takes too long. I though it had to do with the fact that I had too many content-types and fields (~500), but when I load the devel module to see the queries that take that long I see: Executed 32212 queries in 12267.57 milliseconds. Queries taking longer than 5 ms and queries executed more than once, are highlighted. Page execution time was 55763.32 ms When I see the details I notice that the vast majority of db calls come from the menu system, e.g.: _menu_route menu_local_tasks admin_menu_link_save Why is that? Can I avoid some of these? It doesn't seem logical!

• How to update mutual entries in DB?

  - by Sthita

  I am not able to perform mutual update to my Database. My Requirement is like this : Insert IDS UPDate DB Entries ID ConnectedTo ID connectedTo connectedVia 2 1 --- No Entry ----- 2 3 -- No Entry ----- When ID 1 Comes in to picture (Enties happened to Table) 1 4 1 3 2 1 5 2 4 1 1 2 2 5 1 When ID 3 Comes into picture (Enties happened to Table) 3 4 3 5 1 3 1 ---- 3 2 ---- Similarly when ID 4 Comes in to picture 4 9 4 2 3 4 10 4 5 1 4 3 4 2 1 4 1 1 9 4 1 10 4 Its basically Updating the mutual connections.No Duplicate entries should happen. Like for example 2 3 and 3 2 are mutually connected and 1 is associated with them so there is no need to insert (3 2 via 1). I think this is my requirement. Anything possible combinations i have missed please let me know. i will Update. Please help me writing the logic or any example using jdbc and java.

• Implicit type conversion in DB/2 inserts?

  - by IronGoofy

  We're using SQL Inserts to insert some data via a script into DB/2 tables, e.g. CREATE TABLE TICKETS (TICKETID VARCHAR(10) NOT NULL); On my home installation, this statement works fine (note that I'm using an integer which is autoatically cast into a VarChar): INSERT INTO TICKETS (TICKETID) VALUES (1); while at my customer's site I get a type error. My question(s): Is this behavior version dependent? (I use a DB2 Express V9.7, while the customer has an Enterprise V9.5) Is there a config option to change the behavior? (I would like my home install to behave as close as possible as the production environment is going to be.)

• PHP: reusing database class

  - by citricsquid

  Hi, I built a class that allows me to do: $db->query($query); and it works perfectly, although if I want to do: $db->query($query); while($row = $db->fetch_assoc()){ $db->query($anotherquery); echo $db->result(); } it "breaks" the class. I don't want to constantly have to redeclare my class (eg: $seconddb = new database()), is there a way to get around this? I want to be able to reuse $db within $db, without overwriting the "outside" db. currently I'm create an array of data (from db-fetch_assoc() then doing a foreach and then doing the db call inside that: $db->query('SELECT * FROM table'); while($row = $db->fetch_assoc()){ $arr[] = $row; } foreach($arr as $a){ $db->query(); // query and processing here } Is this the best method or am I missing the obvious? Should I consider passing a connection link ID with the database connection?

• .NET DB Query Without Allocations?

  - by Michael Covelli

  I have been given the task of re-writing some libraries written in C# so that there are no allocations once startup is completed. I just got to one project that does some DB queries over an OdbcConnection every 30 seconds. I've always just used .ExecuteReader() which creates an OdbcDataReader. Is there any pattern (like the SocketAsyncEventArgs socket pattern) that lets you re-use your own OdbcDataReader? Or some other clever way to avoid allocations? I haven't bothered to learn LINQ since all the dbs at work are Oracle based and the last I checked, there was no official Linq To Oracle provider. But if there's a way to do this in Linq, I could use one of the third-party ones.

• How can I "bulk paste" a clipboard string of multi-line text into a readable ordered list?

  - by gunshor

  How can I "bulk paste" a clipboard string of multi-line text into a readable ordered list? I'm trying to demonstrate how to turn any string of multi-line text into an ordered list. The script (preferably JS) needs to respect: - carriage returns at the end of a line, to mean "that line ends here" - indentations at the beginning of a line, to mean "this is part of the item above it" - dashes at the beginning of a line, to mean "this is a task, and the line above it is its project"

• Multi-base conversion - using all combinations for URL shortener

  - by Guffa

  I am making an URL shortener, and I am struggling with the optimal way of encoding a number (id) into a character string. I am using the characters 0-9,A-Z,a-z so it will basically be a base-62 encoding. That is pretty basic, but it doesn't make use of all possible codes. The codes that it would produce would be: 0, 1, ... y, z, 10, 11, ... zy, zz, 100, 101, ... Notice that the codes 00 to 0z is not used, the same for 000 to 0zz, and so on. I would like to use all the codes, like this: 0, 1, ... y, z, 00, 01, ... zy, zz, 000, 001, ... It would be some combination of base-62 and base-63, with different bases depending on the position... Using base-62 is easy, for example: create procedure tiny_GetCode @UrlId int as set nocount on declare @Code varchar(10) set @Code = '' while (@UrlId > 0 or len(@Code) = 0) begin set @Code = substring('0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz', @UrlId % 62 + 1, 1) + @Code set @UrlId = @UrlId / 62 end select @Code But I haven't yet managed to make a multi-base conversion out of it, to make use of all the codes.

• Generic Dictionary and generating a hashcode for multi-part key

  - by Andrew

  I have an object that has a multi-part key and I am struggling to find a suitable way override GetHashCode. An example of what the class looks like is. public class wibble{ public int keypart1 {get; set;} public int keypart2 {get; set;} public int keypart3 {get; set;} public int keypart4 {get; set;} public int keypart5 {get; set;} public int keypart6 {get; set;} public int keypart7 {get; set;} public single value {get; set;} } Note in just about every instance of the class no more than 2 or 3 of the keyparts would have a value greater than 0. Any ideas on how best to generate a unique hashcode in this situation? I have also been playing around with creating a key that is not unique, but spreads the objects evenly between the dictionaries buckets and then storing objects with matched hashes in a List< or LinkedList< or SortedList<. Any thoughts on this?

• Mapping issue with multi-field primary keys using hibernate/JPA annotations

  - by Derek Clarkson

  Hi all, I'm stuck with a database which is using multi-field primary keys. I have a situation where I have a master and details table, where the details table's primary key contains fields which are also the foreign key's the the master table. Like this: Master primary key fields: master_pk_1 Details primary key fields: master_pk_1 details_pk_2 details_pk_3 In the Master class we define the hibernate/JPA annotations like this: @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "idGenerator") @Column(name = "master_pk_1") private long masterPk1; @OneToMany(cascade=CascadeType.ALL) @JoinColumn(name = "master_pk_1", referencedColumnName = "master_pk_1") private List<Details> details = new ArrayList<Details>(); And in the details class I have defined the id and back reference like this: @EmbeddedId @AttributeOverrides( { @AttributeOverride( name = "masterPk1", column = @Column(name = "master_pk_1")), @AttributeOverride(name = "detailsPk2", column = @Column(name = "details_pk_2")), @AttributeOverride(name = "detailsPk2", column = @Column(name = "details_pk_2")) }) private DetailsPrimaryKey detailsPrimaryKey = new DetailsPrimaryKey(); @ManyToOne @JoinColumn(name = "master_pk_1", referencedColumnName = "master_pk_1", insertable=false) private Master master; The goal of all of this was that I could create a new master, add some details to it, and when saved, JPA/Hibernate would generate the new id for master in the masterPk1 field, and automatically pass it down to the details records, storing it in the matching masterPk1 field in the DetailsPrimaryKey class. At least that's what the documentation I've been looking at implies. What actually happens is that hibernate appears to corectly create and update the records in the database, but not pass the key to the details classes in memory. Instead I have to manually set it myself. I also found that without the insertable=true added to the back reference to master, that hibernate would create sql that had the master_pk_1 field listed twice in the insert statement, resulting in the database throwing an exception. My question is simply is this arrangement of annotations correct? or is there a better way of doing it?

• Selecting a multi-dimensional array in LINQ

  - by mckhendry

  I have a task where I need to translate a DataTable to a two-dimensional array. That's easy enough to do by just looping over the rows and columns (see example below). private static string[,] ToArray(DataTable table) { var array = new string[table.Rows.Count,table.Columns.Count]; for (int i = 0; i < table.Rows.Count; ++i) for (int j = 0; j < table.Columns.Count; ++j) array[i, j] = table.Rows[i][j].ToString(); return array; } What I'd really like to do is use a select statement in LINQ to generate that 2D array. Unfortunately it looks like there is no way in LINQ to select a multidimensional array. Yes, I'm aware that I can use LINQ to select a jagged array, but that's not what I want. Is my assumption correct, or is there a way to use LINQ to select a multi-dimensional array?

• has_many :through formtastic multi-select field

  - by Tristan O'Neil

  I'm trying to set up a many to many relationship using the has_many :through method and then use a multi-select field to setup the relationships. I'm following this tutorial: http://asciicasts.com/episodes/185-formtastic-part-2 However for some reason the form displays a strange hex number and it changes each page refresh, I'm not exactly sure what I'm doing wrong. Below is my model/view code. company.rb has_many :classifications has_many :sics, :through => :classifications sic.rb has_many :classifications has_many :companies, :through => :classifications classification.rb belongs_to :company belongs_to :sic _form.html.erb <% semantic_form_for @company do |f| %> <% f.inputs do %> <%= f.input :company %> <%= f.input :sics %> <% end %> <%= f.buttons %> <% end %> Also here is the the form looks like it's showing the correct number of entries for the field but it is clearly not showing the correct name for the relationship.

• Passing variables across a multi page form in php

  - by Chris

  Forgive me as I am a newbie. I have a multi page form in which I am using $_SESSIONS to record the variables. <?php session_start(); foreach ( $_POST as $key=>$value ) { if ( $key!="submit" ) { $value= htmlentities(stripslashes(strip_tags($value))); $_SESSION[$key] = $value; } }` I have two problems actually. When I get to a checkform.php that I made that prints out the variables, The variables from page 1 doesn't show up even though that code listed above is on each page. I am using Firefox web developers tool to disable cookies and in the php ini, I altered session.use_trans_sid to 1 to turn it on. For the final page on my checkform.php I print_r($_POST) for the final page which works fine. Why doesn't variables from page 1 not show up? What am I missing? The 2nd problem is that when I print_r($_SESSION), some fields, specifically the checkbox arrays, print as [payment] => Array [agerange] => Array [meals] => Array [mealtypes] => Array What am I missing?

• Multi-table Update(MySQL)

  - by smokinguns

  Hey all, I have a question regarding multi-table update(MySQL). Consider table t1 and t2. The PKEY for t1 is 'tid' which is a foreign Key in t2. There is a field "qtyt2" in t2 which depends on a field called "qtyt1" in table t1. Consider the foll SQL statement: UPDATE t2,t1 SET t2.qtyt2=IF(( t2.qtyt2- t1.qtyt1 )<0,0,( t2.qtyt2- t1.qtyt1 ) ), t1.qtyt1 ="Some value.." where t2.tid="some value.." AND t2.tid=t1.tid In this example qtyt2 depends on qtyt1 for update and the latter itself is updated.Now the result should return 2 if two rows are updated. Is there a guarantee that the fields will be updated in the order in which they appear in the statement( first qtyt2 will be set and then qtyt1).Is it possible that qtyt1 will be set first and then qtyt2? Is the order of tables in the statement important (UPDATE t2, t1 or UPDATE t1,t2)? I found that if I wrote "UPDATE t1,t2" then only t1 would get updated, but on changing the statement to "UPDATE t2,t1" everything worked correctly.

• Validation with State Pattern for Multi-Page Forms in ASP.NET

  - by philrabin

  I'm trying to implement the state pattern for a multi-page registration form. The data on each page will be accumulated and stored in a session object. Should validation (including service layer calls to the DB) occur on the page level or inside each state class? In other words, should the concrete implementation of IState be concerned with the validation or should it be given a fully populated and valid object? See "EmptyFormState" class below: namespace Example { public class Registrar { private readonly IState formEmptyState; private readonly IState baseInformationComplete; public RegistrarSessionData RegistrarSessionData { get; set;} public Registrar() { RegistrarSessionData = new RegistrarSessionData(); formEmptyState = new EmptyFormState(this); baseInformationComplete = new BasicInfoCompleteState(this); State = formEmptyState; } public IState State { get; set; } public void SubmitData(RegistrarSessionData data) { State.SubmitData(data); } public void ProceedToNextStep() { State.ProceedToNextStep(); } } //actual data stored in the session //to be populated by page public class RegistrarSessionData { public string FirstName { get; set; } public string LastName { get; set; } //will include values of all 4 forms } //State Interface public interface IState { void SubmitData(RegistrarSessionData data); void ProceedToNextStep(); } //Concrete implementation of IState //Beginning state - no data public class EmptyFormState : IState { private readonly Registrar registrar; public EmptyFormState(Registrar registrar) { this.registrar = registrar; } public void SubmitData(RegistrarSessionData data) { //Should Validation occur here? //Should each state object contain a validation class? (IValidator ?) //Should this throw an exception? } public void ProceedToNextStep() { registrar.State = new BasicInfoCompleteState(registrar); } } //Next step, will have 4 in total public class BasicInfoCompleteState : IState { private readonly Registrar registrar; public BasicInfoCompleteState(Registrar registrar) { this.registrar = registrar; } public void SubmitData(RegistrarSessionData data) { //etc } public void ProceedToNextStep() { //etc } } }

• Sending multi-part email from Google App Engine using Spring's JavaMailSender fails

  It works without the multi-part (modified from the example in Spring documentation): final MimeMessagePreparator preparator = new MimeMessagePreparator() { public void prepare(final MimeMessage mimeMessage) throws Exception { final MimeMessageHelper message = new MimeMessageHelper( mimeMessage); message.setTo(toAddress); message.setFrom(fromAddress); message.setSubject(subject); final String htmlText = FreeMarkerTemplateUtils .processTemplateIntoString(configuration .getTemplate(htmlTemplate), model); message.setText(htmlText, true); } }; mailSender.send(preparator); But once I change it to: final MimeMessagePreparator preparator = new MimeMessagePreparator() { public void prepare(final MimeMessage mimeMessage) throws Exception { final MimeMessageHelper message = new MimeMessageHelper( mimeMessage, true); ... message.setText(plainText, htmlText); } }; mailSender.send(preparator); I get: Failed message 1: javax.mail.MessagingException: Converting attachment data failed at com.google.appengine.api.mail.stdimpl.GMTransport.sendMessage(GMTransport.java:231) at org.springframework.mail.javamail.JavaMailSenderImpl.doSend(JavaMailSenderImpl.java:402) ...

• Algorithm to detect how many words typed, also multi sentence support (Java)

  - by Alex Cheng

  Hello all. Problem: I have to design an algorithm, which does the following for me: Say that I have a line (e.g.) alert tcp 192.168.1.1 (caret is currently here) The algorithm should process this line, and return a value of 4. I coded something for it, I know it's sloppy, but it works, partly. private int counter = 0; public void determineRuleActionRegion(String str, int index) { if (str.length() == 0 || str.indexOf(" ") == -1) { triggerSuggestionList(1); return; } //remove duplicate space, spaces in front and back before searching int num = str.trim().replaceAll(" +", " ").indexOf(" ", index); //Check for occurances of spaces, recursively if (num == -1) { //if there is no space //no need to check if it's 0 times it will assign to 1 triggerSuggestionList(counter + 1); counter = 0; return; //set to rule action } else { //there is a space counter++; determineRuleActionRegion(str, num + 1); } } //end of determineactionRegion() So basically I find for the space and determine the region (number of words typed). However, I want it to change upon the user pressing space bar <space character>. How may I go around with the current code? Or better yet, how would one suggest me to do it the correct way? I'm figuring out on BreakIterator for this case... To add to that, I believe my algorithm won't work for multi sentences. How should I address this problem as well. -- The source of String str is acquired from textPane.getText(0, pos + 1);, the JTextPane. Thanks in advance. Do let me know if my question is still not specific enough.

• remove specific values from multi value dictionary

  - by Anthony

  I've seen posts here on how to make a dictionary that has multiple values per key, like one of the solutions presented in this link: Multi Value Dictionary it seems that I have to use a List< as the value for the keys, so that a key can store multiple values. the solution in the link is fine if you want to add values. But my problem now is how to remove specific values from a single key. I have this code for adding values to a dictionary: private Dictionary<TKey, List<TValue>> mEventDict; // this is for initializing the dictionary public void Subscribe(eVtEvtId inEvent, VtEvtDelegate inCallbackMethod) { if (mEventDict.ContainsKey(inEvent)) { mEventDict[inEvent].Add(inCallbackMethod); } else { mEventDict.Add(inEvent, new List<TValue>() { v }); } } // this is for adding values to the dictionary. // if the "key" (inEvent) is not yet present in the dictionary, // the key will be added first before the value my problem now is removing a specific value from a key. I have this code: public void Unsubscribe(eVtEvtId inEvent, VtEvtDelegate inCallbackMethod) { try { mEventDict[inEvent].Remove(inCallbackMethod); } catch (ArgumentNullException) { MessageBox.Show("The event is not yet present in the dictionary"); } } basically, what I did is just replace the Add() with Remove() . Will this work? Also, if you have any problems or questions with the code (initialization, etc.), feel free to ask. Thanks for the advice.

• Multi-accordion help (CSS issue maybe?)

  - by Josh

  So, I've been trying to develop this multi-accordion news section for this site. It's actually all working, thanks to an insightful plugin. I've modified it a little bit so it works as I want it to, but I've run into two issues, one which is possibly CSS. Issue #1: The idea for the user is that when they view this page, they see all the recent headlines. They can also see who it has been posted by and how many comments have been made to this article. If they wish, they can then click on the headline and the field will expand into the article. They can then either make a comment or view the comments via clicking the View Comments link or clicking the "number of comments" link in the "Posted by..." area (a shortcut to the comments basically). The problem I'm having is if I make the AUTHOR or the "0" comments a link, it breaks the accordion because the accordion uses an A CLASS to open it up. I'm looking for a fix, I've tried making it a H1 or a DIV but that also breaks it. Issue #2: This is a pretty picky one, but when you click the headline it expands, but at least in Firefox (haven't tested it in Chrome yet) the text jumps from the right and to the left, locking in place from which the CSS tells it to (padding-left). I don't know why it's exactly doing that, if anyone has any insight on that, it'd be appreciated. A two-parter to this issue is when you open the Headline to the article and then decide to close the article by clicking on the Headline, parts of the accordion jumps from the darker purple to the light purple before the task is finished. I'm also interested fixing this, but this issue in its entirety are all pretty nit picky things. You can view the demo of the site here: http://www.notedls.com/demo Please if anyone has any advice or fixes, I'd appreciate it, I've been trying to get this all to work to the best of my ability, but I'm clearly no guru or expert. Thanks!
