  • What kind of events should be created for a CRUD application?

    - by Mohit Deshpande
    I have an application that is centered around a database (ORM is LINQ-SQL) that has a table called Assignment. I am using the repository pattern to manipulate the database. My application is basically going to perform CRUD operations. I am new to delegates and events and I am asking you what events I should create (like maybe AssignmentCreating, AssignmentCreated) and what kind of delegate to use (like maybe a custom delegate or just an EventHandler)?

  • Convert a value based on range

    - by Chris
    I need to convert a number to another value based on a range: ie: 7 = "A" 106 = "I" I have a range like this: from to return-val 1 17 A 17 35 B 35 38 C 38 56 D 56 72 E 72 88 F 88 98 G 98 104 H 104 115 I 115 120 J 120 123 K 123 129 L 129 infinity M The values are fixed and do not change. I was thinking a lookup table would be required, but is there a way it could be done with a function on an analytics function inside of oracle?

  • How to implement a link that can get bonus for 5 times by different people on a Social Network?

    - by Jian Lin
    How can we generate a link that can be clicked on by 5 different people on a Social Network game, so that each of the five people can get a bonus? The link will be published as a "newsfeed" on the Social Network such as Facebook. The link shouldn't be easily "generated" by any people as a cheating method. Also, what database table(s) should be added to handle: 1) the bonus can be claimed up to 5 times 2) must be claimed by different people ?

  • VSTS 2008 Database Edition doesn't seem to know 'DATEADD' constants, any ideas?

    - by Marcel Marchon
    I'm trying to implement a database build using VSTS 2008 Database Edition. The build always fails on the following constraint: ALTER TABLE [dbo].[tablename] ADD CONSTRAINT [DF_tablename_date] DEFAULT (CONVERT([varchar],dateadd(hour,(-1),getdate()),(1))) FOR [date]; The error that it shows is the following: TSD03082: The name "hour" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted. Anybody have an idea what is wrong here?

  • h2 in-memory tables, remote connection

    - by Carolyn
    I am having problems with creating an in memory table, using H2 database, and accessing it outside of the JVM it is created and running in. The documentation structures the url as "jdbc:h2:tcp:///mem:' I've tried many combinations, but simply cannot get the remote connection to work. Is this feature working, can anyone give me the details of how they used this.

  • Need help with joins in sqlalchemy

    - by Steve
    I'm new to Python, as well as SQL Alchemy, but not the underlying development and database concepts. I know what I want to do and how I'd do it manually, but I'm trying to learn how an ORM works. I have two tables, Images and Keywords. The Images table contains an id column that is its primary key, as well as some other metadata. The Keywords table contains only an id column (foreign key to Images) and a keyword column. I'm trying to properly declare this relationship using the declarative syntax, which I think I've done correctly. Base = declarative_base() class Keyword(Base): __tablename__ = 'Keywords' __table_args__ = {'mysql_engine' : 'InnoDB'} id = Column(Integer, ForeignKey('Images.id', ondelete='CASCADE'), primary_key=True) keyword = Column(String(32), primary_key=True) class Image(Base): __tablename__ = 'Images' __table_args__ = {'mysql_engine' : 'InnoDB'} id = Column(Integer, primary_key=True, autoincrement=True) name = Column(String(256), nullable=False) keywords = relationship(Keyword, backref='image') This represents a many-to-many relationship. One image can have many keywords, and one keyword can relate back to many images. I want to do a keyword search of my images. I've tried the following with no luck. Conceptually this would've been nice, but I understand why it doesn't work. image = session.query(Image).filter(Image.keywords.contains('boy')) I keep getting errors about no foreign key relationship, which seems clearly defined to me. I saw something about making sure I get the right 'join', and I'm using 'from sqlalchemy.orm import join', but still no luck. image = session.query(Image).select_from(join(Image, Keyword)).\ filter(Keyword.keyword == 'boy') I added the specific join clause to the query to help it along, though as I understand it, I shouldn't have to do this. image = session.query(Image).select_from(join(Image, Keyword, Image.id==Keyword.id)).filter(Keyword.keyword == 'boy') So finally I switched tactics and tried querying the keywords and then using the backreference. However, when I try to use the '.images' iterating over the result, I get an error that the 'image' property doesn't exist, even though I did declare it as a backref. result = session.query(Keyword).filter(Keyword.keyword == 'boy').all() I want to be able to query a unique set of image matches on a set of keywords. I just can't guess my way to the syntax, and I've spent days reading the SQL Alchemy documentation trying to piece this out myself. I would very much appreciate anyone who can point out what I'm missing.

  • Hibernate orm for a view

    - by EugeneP
    How do you ORM a view? Is there any difference with a table in terms of reverse engineering? In my case, I have a whole pile of joined tables that will be read-only in an application. So, if I need sort of a 1 Object with all collections in proper order, instead of long chains of relationships - collection with another etc, it'll be simpler. What do you think and how do you accomplish this?

  • How to set up my belongs_to and has_many reference

    - by dagda1
    Hi, I have an ExpenseType object that I have created with the following migration: class CreateExpenseTypes < ActiveRecord::Migration def self.up create_table :expense_types do |t| t.column :name, :string, :null => false t.timestamps end end I can see the table name is the pluralised expense_types. My question is, how do I reference this type in a belongs_to relationship? Is it: belongs_to :expensetype or is it belongs_to :expense_type I do not seem able to set it up correctly. Cheers

  • Need to remotely create an ODBC connection to a SQl server.

    - by kris
    I have an Access 2007 database with a table in it that is linked to a SQL server. I need to roll this version of the database out to approximately 10 people in different states. In order to do that, they need an ODBC connection to the SQL server installed on their machines. I am looking for a way to do this remotely. Either through VBA in the database itself or perhaps a Batch file linked to their shortcut....I am open to ideas....

  • realloc - converting int to char

    - by Mike
    I'm converting an array of integers into a char by iterating through the whole array, and then I'm adding the resulting string to ncurses's method new_item. For some reason I'm doing something wrong the way I reallocate memory, thus I get the the first column as: -4 Choice 1 0 Choice 1 4 Choice 2 1 Choice 1 4 Choice 3 - Instead of - 2 Choice 1 4 Choice 4 3 Choice 1 4 Exit 4 Choice 1 - #include <stdio.h> #include <stdlib.h> #include <curses.h> #include <menu.h> #define ARRAY_SIZE(a) (sizeof(a) / sizeof(a[0])) #define CTRLD 4 char *choices[] = { "Choice 1", "Choice 2", "Choice 3", "Choice 4", "Exit", }; int table[5]={0,1,2,3,4}; int main() { ITEM **my_items; int c; MENU *my_menu; int n_choices, i; ITEM *cur_item; initscr(); cbreak(); noecho(); keypad(stdscr, TRUE); n_choices = ARRAY_SIZE(choices); my_items = (ITEM **)calloc(n_choices + 1, sizeof(ITEM *)); // right here char *convert = NULL; for(i = 0; i < n_choices; ++i){ convert = (char *) realloc (convert, sizeof(char) * 4); sprintf(convert, "%i", table[i]); my_items[i] = new_item(convert, choices[i]); } my_items[n_choices] = (ITEM *)NULL; my_menu = new_menu((ITEM **)my_items); mvprintw(LINES - 2, 0, "F1 to Exit"); post_menu(my_menu); refresh(); while((c = getch()) != KEY_F(1)) { switch(c) { case KEY_DOWN: menu_driver(my_menu, REQ_DOWN_ITEM); break; case KEY_UP: menu_driver(my_menu, REQ_UP_ITEM); break; } } free(convert); unpost_menu(my_menu); free_item(my_items[0]); free_item(my_items[1]); free_item(my_items[2]); free_item(my_items[3]); free_item(my_items[4]); free_menu(my_menu); endwin(); }
