Is it possible to get the sql script for creating the database, when using Entity Framework 4.0 code first, without using the designer? When i use the designer it creates an .....edmx.sql file with the script. But i don't want to use the designer.

This is a simplified example of what I need. Imagine a person table with several different club tables. Every person can belong to any number of clubs, but must belong to at least one club. The association would be a 1 to zero or one between the person table and each of the club tables.I've created the databases, then the entity model. The associations are all 1 to many, which isn't what I want.
Is there a way to modify the database so that the model is created correctly? I'm still building the project, making lots of changes, and I've had problems with updating the model, so I keep recreating it. Setting up the database correctly would be preferable.I'm trying to follow the quickstart here: [URL]but I'm using the SQL Management Studio designer, and I can't find how to fix the associations I add.
I've been reading about using or not using foreign keys in the model, but it's only confused me more. Can someone help me understand this? I'm starting to write code with what I have, and I'm running into problems. I'm about to start using joins, which means I'm trying to use a hammer instead of a saw because I don't know how to use my saw. I'd rather understand my tools and use them the right way!
I have been reading the below article and I have got it to work.

The problem is when I use my database script file it throws an error 1001 saying error next to keyword 'GO'. But if i take the exact same script and run it in SQL Management Studio it works fine.
Try this small script, this is what I am using and its giving me an error, An above is a lovely article to creating a database from microsoft.

View 8 RepliesI am currently using datasets for my data access layer. I currently store the connection string in the web.config file. I need the ability to change the connection to another database before any queries are processed. Is there an event that is triggered or a base class that can be modified that intercepts the process of retrieving the connection string from the web.config file? Is there any way to handle multiple database connections using the same code base and also take advantage of the connection pooling? I understand the best method is to get rid of datasets and use custom data objects.
View 2 RepliesI want to create web application. I use SqlServer 2008 and asp.net (framework 3.5 sp1).
In my task, user can create database arbitrary structure. and i must write system that generate web site by template. is it possible?
I want to start creating sites with simple backends! I don't know much about databases though and I don't want to jump straight into creating sites with databases anyway. So I want to find out what the best way of creating a simple backend without using a database is.
I have an asp.net webpage which is a prices page detailing the prices of services at a hair salon. The prices change every 6 months so I want to give the client a simple backend so he can update the prices himself. The backend will just be a table of inputs populated with the current prices which can be changed and then click 'save changes' to update the site.
Now what is the best way of implementing this?
A) In the prices page, hard code an html table, within each cell code a <span> tag with an id for the price that will go within the span tag like id="menscut" and within the span tag hard code the price of the service. Then wirte a C# class called 'edit' that is used when the 'save changes' button is clicked on the backend page. When 'save changes' is clicked the 'edit' class parses the prices.aspx page and finds <span id="menscut">£20</span> and then changes it to <span id="menscut">£22</span> (or what ever new price has been entered in the backend) and then saves the new edited prices.aspx page over the old one on the server.
or
B) Don't hard code prices into the prices.aspx but instead store the prices in a seperate .txt or .xml file. Every time the prices.aspx page loads it runs a class called 'populate' which extracts the prices from the .txt file or .xml file and inserts them into the table in the prices.aspx page. And now the edit class instead of editing the prices.aspx page it edits the .txt or .xml file.
So which of those ways is better, or if they are fairly even pegged what are the pros and cons of each?
Or are there any other options I haven't thought of?
I am planning to develop around 4 product catalogue websites. The functionality of all the websites would be same. however the design, images and css would be different.
All the 4 websites will use the same admin panel, forums and database(MS Access) also.
How should I create such a system.
I dont understand what kind of folder structure should I create.
I would like to create following kind of folder structure.
(Root Folder)Admin Website ----> Website 1 (subfolder)
----> Website 2 (subfolder)
----> Website 3 (subfolder)
----> Website 4 (subfolder)
Root folder will have the database and all the common files.
Unfortunately, when I tried to create such structure, Dot Net Didnt allow me to create one website inside another
what kind of system should I use for maximum reusability.
I am a small time freelancer and cannot afford to build seperate websites for each of my client.
I've created a web application that's using Windows Authentication using roles authorization.
In VS2008 everything's runs fine by running the app or browsing using the VS web server.
I create a new virtual App in IIS6 and then try to browse the page. The app hangs, and has a very mysterious habit of creating a new SQL Server Express database in our appdata directory called TimeTracker.MDF.
So I was thinking somewhere along the line we installed a TimeTracker Starter Kit and it updated a configuration file somewhere.
My initial reaction was to search all of the config files under the framework directories. So i did that using Windows GREP, only to find one entry here:

I have created a database in Access 2007 for a university. Now, a new functionallity is required. What I need to do is a search function where students can search the database online. Now, they can only search using a front-end which is read-only, but they need to use a computer with Microsoft Access (or Runtime) and they need to be connected to the back-end which is located on a server.
make the database to work online? I am a novice to web programming. Which is the easiest way and how do I start?
The database has fields with Attachments. The students can search the database and open Attachments connected to the found posts, this part needs to be online. The personnel can edit and add data using a more complex front-end. This does not need to be online, they can still use Access.
I have created class in C# i need to use objects from this class to add them to a databse table.

where all.q is allocated quantity for that size
while the sizes & qty r called from a size table in the database.

I was trying to implement as above. How can i call this class from the code behind of my page, and call the methods Open and Close connection ?
How do i instantiate the object ?
Never really worked with the asp tables but for this project it makes more sense, I am having trouble addding rows dynamically from the sql datatable i am pulling. In hte datatable it has 12 rows with 14 columns, I need to make this into a table, with a dtagrid I would be done but I have to pull other data that they could add columns, so a table I am told is easier.
This gets my data and I can see it
mydataTable = new DataTable
mydataTable = GetData(sql)
mydataTable.add.row(myDataTable.rows(0)(0))
I get nothing but errors trying to do this, what is the correct way to add rows to an asp.net table
Can I add this all to a datagrid and then add the extra columns I need if they are there with out using a table.
i am creating some of the control at runtime according database values. problem is that when i click onto the button, if the text box is empty, the required field validator(genrated at runtime) show first time that the text box is empty. but one agin i click on to the button, it doest show any error messege and all of the control which i am genrating at run time are hiding when i see at the page source, no control is find there.

I am using ASP.NET 2008 Visual Basic Language. I tried to create a function that multiply two values from two different tables and get the result presented in a label. The value is retrieved by referring to the primary key after the user selects from a DropDownList which is in another page using sessions.
I tried to build this code in the Load_Page event but it didn't display for me the total.

Creating a login for a website that checks against a database table.

I've got a MS SQL (Express) database. its quite complex and uses a lot of tables. Is there a way to generate a SQL script for creating the complete database, but not the content of it.
I like to copy the database. Right now i copy the database. After that i need manually to clear all fields. There are also some relationships, so its a lot of work to clear all of it manually.
I am having problem when i was trying to attach .mdf file while create a new connection of SQL server, create a new connection of SQL database file and open the database in Server Explorer. I am using VS 2010 Ultimate and SQL Express 2008 R2.

2. Create a new SQL server and attach .mdf
If I have a DataTable (in-memory) read by my C# program from a flat file, and I want to create it as a new table in a SQL Server database... what is the simplest way to do that?
It seems like something like SqlBulkCopy with an option to create a new destination SQL server table would be on my line of thinking, but I dont see a way.
I have entries for an enumeration stored inside a database table with only the following fields: ID and Name. I want to show the values stored inside this table inside a DropDownList on a form. The user then chooses a value and submits the form.
I found a way to easily create a DropDownList from an enumeration (although it would probably be best to just populate the DropDownList with the Name fields of all the records in the table). However, I haven't found a way to later bind the DropDownList in the form submission to an integer value to put into the database (FK - PK) with the other form values.
is it possible to fetch DropDownList content via AJAX and have it be put into the DropDownList and into the SelectList in the ViewModel (with both the ID and Name parameters)? I want to selectively fetch content based on an input the user makes and I want the ViewModel to then be filled with that fetched data.
