  • SQL Server ALTER TABLE ADD Column

    This article covers SQL Server ALTER TABLE ADD Column Statement. In addition, we will learn how to add a value for the columns in the default value and update a value later in a large table. You must also add new columns to a table to be added by database developers.

    I would have thought it would be a little difficult adding columns in SQL Server databases. Occasionally, you may add the columns in SQL Server management studio itself.

Of course I can accomplish this with multiple catch blocks, but when they all do common things I would like a simpler way to avoid code duplication. Another great example would be how to use C# Convert any value to a boolean.

  • Updating specific fields using Entity Framework

    Entity framework does a great job of detecting when a field changes on any object that it is tracking. These changes will be automatically saved when SaveChanges is executed. As I discussed in Why the Repository Pattern I like to create an example Generic Class that is type T where T is a Model or a User in my Entity Framework Context.
