  • Postgres vs Firebird

    - by Tedi
    I'm looking to use either Firebird or Postgres in my next development project ... largely because both are available under a BSD-like license. I found a great comparison of the two database at http://www.amsoftwaredesign.com/pg_vs_fb But this comparison is a good 2+ years old and both databases have come a long ways since. Does anyone mind updating the comparison table to be relevant for the current versions of both Firebird and Postgres ... or have a link to a site that does a good recent comparison between the two database?

  • MySQL Many to Many with Unique keys and Update/Select if Exists otherwise Insert

    - by Jayrox
    In my goal to have a Many-to-Many relationship in my MySQL database I have arrived at another bridge to build. Current Tables: Users (id, name) Tags (id, name) User_Tags (user_id, tag_id) Here is the goal: I would like to have the ability to take a tag i.e: #fb and insert it into my Tags database which has a unique constraint on name and if the tag exists I would like to return it's id I would like to insert the tag.id and the current user's user.id into User_Tags. I do not have any unique constraints on the User_Tags table because I would like to be able to track the user's most commonly used tags and present them in a list ordered by frequency of use. I am currently developing this project in PHP using prepared statements. Additionally, performance is not currently an issue as my user count is still fairly small, but it is steadily growing and may be an issue in the future.

  • Recreating iPhone stock application with nested views

    - by john
    I am trying to create an app similar to the Yahoo Stocks app that comes on the iPhone, with the split-screen interface (table on the top, graph on the bottom). I'm struggling with the view hierarchy. What is the easiest way to implement a split-screen type of application. I basically want two views nested in a parent view. My problem is a little bit more complex because I want functionality like having a uipagecontrol (does this require another viewcontroller, or is simply implemented in the initial view controller)? To what degree do I need to use IB? I would prefer to do this all in Xcode. Thanks in advance!

  • Modifying annotation attribute value at runtime in java

    - by Lici
    Hi folks: some methods in our model pojos have been annotated like this: @Column(name="cli_clipping_id", updatable=false, columnDefinition = "varchar(" + ModelUtils.ID_LENGTH + ") COLLATE utf8_bin") columnDefinition attribute is database vendor dependant, so when trying to drop schema in HSQLDB using Hibernate it fails: [ERROR] 16 jun 12:58:42.480 PM main [org.hibernate.tool.hbm2ddl.SchemaExport] Unexpected token: COLLATE in statement [create table cms.edi_editorial_obj (edi_uuid varchar(23) COLLATE ] To fix this, i'm thinking on this solution (but don't want to spend time if it isn't possible) , at runtime, for each method column annotated: Get @Column annotation Create a copy of the column annotation, setting columnDefinition null using javaassist. set column method annotation to the copy column annotation object overriding the old one (i don't know it this is possible) Is it possible to "hack" these methods this way? Any help would be much appreciated ...

  • Why does php show error for my SQL query

    - by ZincX
    UPDATE: My mistake - I made a typo. Nevermind this question. I'm using php to update a mysql database. The resultant query I'm using when i print it out on my webpage before executing is as follows: INSERT INTO perch2_content_items (itemOrder, regionID, pageID, itemRev, itemID, itemJSON, itemSearch ) SELECT MAX(itemOrder)+1, 105, 81, 11, 118, 'json', 'search' FROM perch2_content_items WHERE regionID=105 When I copy and paste this query directly into the phpmyadmin SQL interface, it works fine. The table gets updated. However, when I try to execute it using my php code as follows, it throws an error. $insertToPerch = "INSERT INTO perch2_content_items (itemOrder, regionID, pageID, itemRev, itemID, itemJSON, itemSearch ) SELECT MAX(itemOrder)+1, $regionID, $pageID, $regionRev, $newItemID, 'json', 'search' FROM perch2_content_items WHERE regionID=$regionID"; mysql_query(insertToPerch) or die(mysql_error()); The error I'm getting is: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'insertToPerch' at line 1 Can anybody help me figure out why it is failing.

  • Handling user security scope with nHibernate or other ORM

    - by Schotime
    How should one handle the situation where you may need to filter by a group of users. Here is the scenario. I have an administrator role in my company. I should be able to see all the data belonging to me plus all the other users who I have control over. A plain old user however should only be able to access their own data. If you are writing regular sql statements then you can have a security table with every user and who they have access too but i'm not sure how to handle this situation in the OO and ORM world. Any one dealt with this scenario in a web application using an ORM? Would love to hear your thoughts!

  • Rails 3: habtm migration, primary key issue

    - by Brian Wigginton
    I'm trying to setup a migration file for a habtm relationship, however when I run the migration I'm getting the following error: Primary key is not allowed in a has_and_belongs_to_many join table (parts_vehicles). Here is my migration file (20110111035950_create_parts_vehicles.rb): class CreatePartsVehiclesJoinTable < ActiveRecord::Migration def self.up create_table :parts_vehicles, :id => false do |t| t.integer :part_id t.integer :vehicle_id end end def self.down drop_table :parts_vehicles end end The documentation example states to use :id => false to disable a primary key from being generated, but I'm still getting the error.

  • OracleDataAdapter returns no rows, but the query string works in SQLDeveloper

    - by belzebu
    visual studion 2008 oracle db 11.1.0.7 oracle client for .NET I have a relatively simple query, that selects the rows from across multiple tables (up to 4) using joins. OracleDataAdapter returns no rows for the only dataset's table, but if I copy and paste that query in SQLDeveloper then I get the desired results. I can get the data from other tables using the adapter with no problem, but it seems like it struggles with the bit longer selection query (string length is ~ 300 (not that much at all)) Connection string for the connection is 100% correct. Any ideas? thank you...

  • PresentModalViewController from within UISplitViewController: weird behavior in landscape mode

    - by Krumelur
    Hi, I've been using PresentModalViewController a lot and never had any issues. But when showing a modal controller from within any controller hosted by a UISplitViewController I get strange orientation bugs. In my table view (which is root controller of the UISplitView), when a cell is touched, I call: MyController oModal = new MyController(); oModal.ModalPresentationStyle = UIModalPresentationStyle.FormSheet; oModal.ModalTransitionStyle = UIModalTransitionStyle.CrossDissolve; this.PresentModalViewControll(oModal, true); If the iPad is in Portrait, all is okay. If it is in landscape however, the modal controller fades in but its orientation is incorrect. Then, after fading in has finished, it suddenly flips 90 degrees and adjusts to correct orientation. I have overriden ShouldAutoRotateToInterfaceOrientation(), so that cannot be it. Ideas? René

  • Sending variables in URLs in PHP with echo

    - by alexpelan
    Hi all, I can't really find good guidelines through google searches of the proper way to escape variables in URLs. Basically I am printing out a bunch of results from a mysql query in a table and I want one of the entries in each row to be a link to that result's page. I think this is easy, that I'm just missing a apostrophe or backslash somewhere, but I can't figure it out. Here's the line that's causing the error: echo "<a href = \"movies.php/?movie_id='$row['movie_id']'\"> Who Owns It? </a> "; and this is the error I'm getting: Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING If you could elaborate in your answers about general guidelines for working with echo and variables in urls, that would be great. Thanks.

  • Idioms for a three-state toggle?

    - by Alex Mcp
    I have a table column where each row has one of three states, and the purpose of the row is to offer manipulation AND display of this property with three states. My current development view is to have three tightly packed radio buttons with labels at the head of the columns (and every 50 rows or so) and onClick they send an AJAX request and thar she blows. This is fugly. Is there a standard idiom for a control like this? I'm currently mocking up something similar to the iPhone on/off toggle, but with a "middle" state. Any input would be welcome.

  • User control blank on form in VS 2008

    - by Eric
    I've created a user control that contains a table layout control with various other standard controls like buttons and labels. Yet when I add the user control to one of my forms the control is blank. I've tried building the solution and a see the user-control flicker as if it's being updated, but it remains blank. Also if I actually run the program the usercontrol can not be see on the form. I've used usercontrols like this in the past. Is there something I'm missing?

  • Importing a CSV file without headers into SQL 2008

    - by Luiggi
    I want to import a CSV with 4,8M records into a SQL 2008 table. I'm trying to do it with the Management Studio wizard but it keeps trying to recognize a header row which the CSV doesnt have. I don't find any option to skip this and although I specify the columns myself, the wizard still tries to find a header row and doesnt import anything without it. The structure of the CSV is "818180","25529","Dario","Pereyra","Rosario","SF","2010-09-02" I've also tried alternatives like BULK INSERT but then I find out that with BULK INSERT I can't import files with a text qualifier.

  • An analog of String.Join(string, string[]) for List<T> or other generic enumerable

    - by abatishchev
    class String contains very useful method - String.Join(string, string[]). It creates a string from an array, separating each element of array with a symbol given. But general - it doesn't add a separator after the last element! I uses it for ASP.NET coding for separating with "<br />" or Environment.NewLine. So I want to add an empty row after each row in asp:Table. What method of IEnumerable<TableRow> can I use for the same functionality?

  • How to manually verify a user against the asp.net memberhip database

    - by Ekk
    I would like to know how I can verify a user's credential against an existing asp.net membership database. The short story is that we want provide single sign on access. So what I've done is to connect directly to the membership database and tried to run a sql query against the aspnet_Membership table: private bool CanLogin(string userName, string password) { // Check DB to see if the credential is correct try { string passwordHash = FormsAuthentication.HashPasswordForStoringInConfigFile(password, "SHA1"); string sql = string.Format("select 1 from aspnet_Users a inner join aspnet_Membership b on a.UserId = b.UserId and a.applicationid = b.applicationid where a.username = '{0}' and b.password='{1}'", userName.ToLowerInvariant(), passwordHash); using (SqlConnection sqlConn = new SqlConnection(ConfigurationManager.ConnectionStrings["LocalSqlServer"].ConnectionString)) using (SqlCommand sqlCmd = new SqlCommand(sql, sqlConn)) { sqlConn.Open(); int count = sqlCmd.ExecuteNonQuery(); sqlConn.Close(); return count == 1; } } catch (Exception ex) { return false; } } The problem is the password value, does anyone know how the password it is hashed?

  • I am attempting to pull all years and terms from database except the last term

    - by Jonathan Moriarty
    I have a logic problem: We have a database that has a donations table with name, address, last donation year, and last donation term (Spring and Fall). We want to pull all donors unless they donated in the last term (Spring or Fall). I have been trying to figure out the logic of pulling all years up to the current year while omitting the last term. So for example this year is 2012 and we are in the Spring term (I defined the spring term between 1/1 and 6/30) so I only want to display donors before and including spring 2011 (we will exclude the current term which is spring 12 and the last term which is fall 2011). The problem is I want to pull sprig 2011, fall 2010, spring 2010 etc, but only omit the current term and last term donated.

    - by Zambouras
    What I am trying to accomplish is using this script task to continually insert into a generated RecordSet I know how to access it in the script however I do not know how to update it after my changes to the DataTable have been made. Code is Below: Dim EmailsToSend As New OleDb.OleDbDataAdapter Dim EmailsToSendDt As New DataTable("EmailsToSend") Dim CurrentEmailsToSend As New DataTable Dim EmailsToSendRow As DataRow EmailsToSendDt.Columns.Add("SiteMgrUserId", System.Type.GetType("System.Integer")) EmailsToSendDt.Columns.Add("EmailAddress", System.Type.GetType("System.String")) EmailsToSendDt.Columns.Add("EmailMessage", System.Type.GetType("System.String")) EmailsToSendRow = EmailsToSendDt.NewRow() EmailsToSendRow.Item("SiteMgrUserId") = siteMgrUserId EmailsToSendRow.Item("EmailAddress") = siteMgrEmail EmailsToSendRow.Item("EmailMessage") = EmailMessage.ToString EmailsToSend.Fill(CurrentEmailsToSend, Dts.Variables("EmailsToSend").Value) EmailsToSendDt.Merge(CurrentEmailsToSend, True) Basically my goal is to create a single row in a new data table.

  • Automatically CONCATENATE text on data entry

    - by Bill T
    I am a newbie and need help. I have a table called "Employees". It has 2 fields [number] and [encode]. I want to automatically take whatever number is entered into [number] and store it in [encode] so that it is preceded by the appropriate amount of 0's to always make 12 digits. Example: user enters '123' into [number], '000000000123' is automatically stored in [encode] user enters '123456789' into [number], '000123456789' is automatically stored in [encode] I think i want to write a trigger to accomplish this. I think that would make it happen at the time of data entry. is that right? The main idea is would be something like this: variable1 = LENGTH [number] variable2 = REPEAT (0,12-variable1) variable3 = CONCATENATE (variable2, [number]) [encode] = variable3 I just don't know enough to make this happen ANY help would be FANTASTIC. I have SQL-SERVER 2005 and both fields are text
