Hi,
look for the HttpRequest and HttpResponse classes, and in particular the HttpResponse.Header property. Once you got the headers, you can extract specific info like so:
IEnumerable<string> values;
if (headers.TryGetValues("X-BB-SESSION", out values))
{
string session = values.First();
}

let me assume that i want to create 2 Tables with FK...etc using C#
what have I from choices.. ADO.Net, Dapper, EF or something else !
- What is the benefit,advantages and disadvantages to use Code First ?
- Should I use normal SQL Server managment Studio to design and create my tables and relationships ?
|
|
|
|
|
I'll throw my opinion into this … but bear in mind that this is only an opinion, I'm sure others will shout me down and that's ok too.
- I cannot think of a single advantage of Code First.
- I personally only ever use SSMS to create my tables, relationships etc.
There are arguments to both sides e.g. entity framework - Code-first vs Model/Database-first[^]

I agree you . i don't like to use EF for many reasons and yes you have right
EF wrote for you everything and that is the part which is almost don't like it
When things go wrong, you are going to need to look deep into the code from EF wrote for you. So how fast can you read and undersatand the generated code so that you can identify what the issue is and how to fix it? and etc etc .. but sometimes it's interesting to create tabels or use Code first using C# Dapper Plus for instance doing great job about it .

I agree with CHill60 - I always use SSMS.
Data design is too important, it needs careful thinking about if it's going to be both performant and flexible. Far, far too easy to "let the machine do it" and it makes unwanted assumptions about your data that lead to problems later.

As far as I can see, Dapper[^] simply maps the query results to objects. It doesn't provide any utilities for creating or maintaining database structure, other than raw ADO.NET commands.

yes you are right . i thought its doing Code First as well.

Depends on whether it is new development or "maintenance".
With new development, the requirements and feasibility (e.g. skills; interfacing) dictate the technology.
With maintenance, you stick with what's there.
(it's never as simple as picking items from a menu).

I generally parallel the tables and classes; generally I will write out the class properties and copy/paste via Excel into a new SSMS query window.
If it is an existing table, I will open in design view; then copy/paste into as the properties of a new class object (again via Excel).

It's interesting.
Are you using VBA code?

No. i am using C#
Sqlcommand to create tables and using Dapper to read,insert ...etc
what do you use or what do you prefer to use ?
|
|

|

Well...
I know that you're using C#. I was asking @MadMyche about using Excel in a process of creating/updating database tables.
|
|
|
|
|
oh ja .. sorry i thought you have asked me .
by the way .. do you use IQueryable with Linq ?
|
|
|
|
|
No to the VBA, no Entity Framework, no LINQtoSQL; I am an ADO purist.
But I'll try to explain the process if it helps. After typing this it does seems really wordy and long but after many years of doing it this way it is only a matter of minutes.
- Create class properties in C#
- Copy the properties and paste in Notepad
- Use find/replace to replace spaces with tabs
- Copy the contents and paste into Excel
- Add column for natural index (1,2,3)
- Sort by Net Data Type
- Add column for SQL Data Type alongside NET data type, and populate
- Rerrange columns around to match format of CREATE TABLE syntax
- Copy and paste the desired columns into SSMS new query window
The process for SQL design to a class is similar.
I also reuse/tweak the Excel content to create instances (overloaded constructs) from IDataReaders or DataRows.

Nice!
Well... I'm lazy, so - probably - i'd prefer to automate it via c# code. I'd create a programme wich will acts as you described in 2-3 and 5-8. I'd save final result in a text file (with .sql extension) and use it in SSMS window.
I like your idea and i really appreciate it.

Glad it can be used, even if it is only inspirational... I guess I'm too lazy to write the program to do it

Having written such a program in the 90's for VB6, reworked for VB.net then for c# and now producing such things as WPF razor page templates and the CRUD stored procs I can relate to that. Except I start from the other end, create the tables in SSMS and then use ClassBuilder to do the bulk of the CRUD code.

Having been a developer for over 20 years, and a SQL DBA and Administrator since 6.5. My Preference is to design the database using Management Studio. I do it this way
#1. Design the raw tables include the fields for the Foreign keys BUT do not link them yet
#2. Design your Clustered indexes I will name them IDX_tablename
#3. Be lazy and use the Database Diagrams tool to define your Foreign Keys
My reason for doing this if the DB is designed correctly your app will be far more stable. If you design your foreign keys first it becomes your clustered indexes and normally you will cluster on a name or account number and not the ID.
