Here I store the hierarchy data for the Organosation. Under_Level_ID denotes under which Level_ID the current Level is lying. e.g. for Branch the hierarchy in above table will be likeHO-->REGION-->Branch & for ZONE the hierarchy will be same as branch. Now my problem is I need all the hierarchy below a given Level. i.e. if am passing 132 as level then the SP should return me all the hierarchy elements lik Zone, Branch, fgfgfhf, Cluster,

I am new to MVC and this really probably should not be posted here but in a different forum topic. The reason I am posting here though is I am not sure if there is something about MVC that would prevent me from doing what I am looking to do.So here it goes.Maybe I am the only one out there that thinks this way but I don't care for and don't fully understand LINQ. I Like building my stored procedures passing my data to a datareader etc... and displaying what I need.
Now that being said I am wanting to learn how to make a true Data Repository and build from there but everything I find online especially here all gives me examples and instructions on how to do so using LINQ.Does anyone know of a site that will teach me how to do this without using LINQ or any form of ORM just allow me to write my stored procs how they need to be and build my classes for data access how they need to be.I may be wrong in this but it seems to me this would be the more light weight way of doing it.Anyhow as stated above the additional question to this would be is there any reason this would not work for MVC and actually any reason it is extremely (or at least for me) hard to find any documentation on this anywhere online?
I wrote a linq code to read from database if its value is equal to textBox that user enters.
I dont wanna show the result in Gridview,so jz I wanna use that value. The code I wrote is
var sql = from x in db.Managers
where x.M_Name == TextBox1.Text.ToString()
select x.M_Name;
in this code I'm selecting only the name that user entered in textBox
so i want to do like tis
String Name = sql.ToString();
means to store the value in string. so the problem is i can not assign the var to string.
Is linq just for retrieving data or can you send data to the database using it?
