Hi Everyone !!

I have created an MVC module template from the package offered by Chris-Hammod https://marketplace.visualstudio.com/...

Effectively and as he explains in his videos, I have a basic module that removes, creates, reads and updates a list of elements with a name and a description.

I am trying to understand all the code to be able to start creating my own and I can not find the script that executes to read, create, delete and edit the elements of the list.

I run an SQLProfiler and I could tell that it does the scripts with a sp_executesql: EJ

exec sp_executesql N'DELETE FROM [DNNModuloPropio_Items] WHERE [ItemId] = @ 0 ', N' @ 0 int ', @ 0 = 3

My problem is that I even debug the code and I can not see where that "DELETE FROM" or "INSERT INTO" is stored. Everything comes to this class and it ends there.

 

 

public void DeleteItem (Item t)

{

  using (IDataContext ctx = DataContext.Instance ())

  {

     var rep = ctx.GetRepository <Item> ();

     rep.Delete (t);

  }

}

 

I remain attentive to your support, thank you very much!

Hi,

The magic is behind DotNetNuke.Data.DataContext class. It's a micro ORM tool that automatically creates SQL statements. It's similar thing like in Linq 2 Sql, Entity Framework, PetaPocoDataContext, etc So in theory developer doesn't need to know SQL to work with databases. See here for reference:

Arnell,

the code is generated by DAL2 (which is more or less the implementation of PetaPOCO in DNN). Nothing to care about...

If you need to execute Stored Procedures you should look at the DAL2 documentation or a module that uses it. The following blog article could be helpful: https://www.dnnsoftware.com/community...

Happy DNNing!

Hello barry!


Now if I have an idea of ​​how all this works in DNN, I made a test creating a new module, added 3 new columns to the table and added the respective classes that would refer to those tables. Indeed, I did not have to write any extra SQL code nor a class that executed the queries to insert, update, delete or obtain the new data.
One last question. Will you have articles that talk about how to execute my own storage procedures?

Arnell,

the link I inserted in my above post has an example how to execute a stored procedure.

Also this blog post could be helpful: http://www.bitboxx.net/Blog/Post/190/...

Happy DNNing!
