Merge two or more existing database tables/columns into one



I have two tables for e.g. tblStudents and tblSchools. Both are having different columns. For a reason I need to merge the two tables into one temporary table.
For example “tblStudents” contains the following design.
StudentIDFirstNameLastNameAddressDOB
Where as “tblSchools” contains the following design.
SchoolIDNameAddressIsSecodarySchool
Now, you would like to merge this two table columns into one temporary table then you can use the following sql script.
SELECT * INTO #tbl_Temp
FROM tblStudent, tblSchool where 1>2
Here, I have mentioned the “where” clause because I wanted to copy only the columns and not the data. You can ignore this clause if you want to copy the entire data too.
You can add as many tables you want to merge by separating with comma (,) between the table names.
You can add specific columns from specific tables by using table alias and column name combination.
For example
SELECT tblStudent.FirstName,tblStudent.LastName,tblSchool.Name INTO #tbl_Temp
FROM tblStudent, tblSchool where 1>2
Happy Programming!

ASP.NET MVC - Set custom IIdentity or IPrincipal

Here's how I do it. I decided to use IPrincipal instead of IIdentity because it means I don't have to implement both IIdentity and IPrincipal. Create the interface interface ICustomPrincipal : IPrincipal { int UserId { get ; set ; } string FirstName { get ; set ; } string LastName { get ; set ; } } CustomPrincipal public class CustomPrincipal : ICustomPrincipal { public IIdentity Identity { get ; private set ; } public bool IsInRole ( string role ) { return false ; } public CustomPrincipal ( string email ) { this . Identity = new GenericIdentity ( email ); } public int UserId { get ; set ; } public string FirstName { get ; set ; } public string LastName { get ; set ; } } CustomPrincipalSerializeModel - for serializing custom information into userdata field in FormsAuthenticationTicket object. public class CustomPrincipalSerializeMode...

linq orderby multiple columns dynamically

So, it's been a while, but I thought I take moment and do my annual blog post ;). I've been playing around with  ASP.NET MVC  and the Linq stuff for  NHibernate  recently. I was in need of an OrderBy extension method that could take a SQL-Like OrderBy string and sort a IQueryable<> or IEnumerable<> collection. I wrote up an implementation that worked, but I just wasn't satisfied with its internals (quite a bit of reflection to get the correct type to construct a LambdaExpression, etc) At any rate, I couldn't leave well enough alone, and, after a bit of Googling, I ran across this  StackOverflow  answer about Dynamic LINQ OrderBy . The extension method wasn't exactly what I was looking for, but that ApplyOrder method is slick, and solved the portion of my implementation that was bothering me. So, I though I would post up my version in case anybody finds it useful. It handles the following inputs: list.OrderBy( "SomeProperty" ); list.Ord...
