Dynamically Create a Database (LINQ to SQL)

Posted By:      Posted Date: September 03, 2010    Points: 0   Category :ASP.Net
 Hello... I want to create an install script for a simple little CMS I have created for myself... I want to pass the connection string and then create my tables. I found the following example on MSDN: http://msdn.microsoft.com/en-us/library/bb399420.aspx My question is how do I pass the username and password to the DB... or even better if there is an example of this somewhere that would be great.   Thanks!

LINQ to SQL - Validating if item is in Database, but if item is not items not inserting into databas



I am new to this, so bear with me.  I am writing an application in C# that uses LINQ to validate a datacontext off a textbox to see if the record exists already.  If the record does exist I inserted an if statement to advise the user that the record exists, if the record does not exist I would like to allow the record to be added to the database.  If I take out my else statement everything works fine as far as inserting goes, but I do not want to allow inserts in this scenario.  I have tried moving the if and else statement to different parts of the code but can't quite figure this one out.  Any help would be apprecaited, attached is the code.  This code is set to a button press.  As a matter of fact, if you see any other errors along the way please feel free to point them out.

Yukon Basics: XML, T-SQL, and the CLR Create a New World of Database Programming


The next version of SQL Server, code-named "Yukon," includes quite a few enhancements and expanded language support. For example, Transact-SQL now conforms more closely to the ANSI-99 SQL specification and makes querying more flexible and expressive. Yukon can execute user-defined functions, stored procedures, and triggers written in CLR-targeted languages, including Visual Basic .NET and C#. It supports a subset of the W3C standard XQuery language, and has native XML support.In this article, the author outlines the most significant language features and builds an order-entry sample app.

Metadata: Create a Database Schema Repository with Meta Data Services in SQL Server 2000


SQL Server 2000 Meta Data Services is a repository technology that stores and manages metadata for SQL Server. Instead of building database schemas over and over, Meta Data Services allows you to freeze an entire schema for use in other projects. You can also use these schemas for training, testing, or debugging. In this article, the authors will review the various components of Meta Data Services and show how it can be programmed using a Visual Basic client, XML, and XSLT. They will also show you how to manage and manipulate your metadata by generating a simple database schema using a SQL Server repository.
