foreignkey relationships not appear in edmx with mysql database with asp mvc with database first

I have connected my asp.net MVC application with MySQL database, and included all the tables in edmx, but there is no relationships appeared in the designer, as shown in the image:
I tried to change the Entity Framework and MySQL ddls in manage nuggets page versions but not worked with me

In MySQL to create FK key:
CREATE TABLE Orders (
OrderID int NOT NULL,
OrderNumber int NOT NULL,
PersonID int,
PRIMARY KEY (OrderID),
FOREIGN KEY (PersonID) REFERENCES Persons(PersonID)
);

in the sql object explorer in your table did you refer to your foreign key
ex : foreign key ([Milstone_Id]) references [db].[your table whith the PK_ID here Milistone] (["name of your FK here" Milstone_Id])

ASP.NET SQL elimininate duplicate Ids

I have two database tables for documenting a wound healing progression. Those are joined over the wound_id-Column like this:
So for one wound, I can create many progresses to show the healing of it. This is working fine.
Here is the code for the tables:
Table wound_details:
CREATE TABLE [dbo].[epadoc_mod_wound_details] (
[wound_id] INT IDENTITY (1, 1) NOT NULL,
[wound_type] VARCHAR (500) NULL,
[wound_description] VARCHAR (500) NULL,
[decuGrade] INT NULL,
[wound_comments] VARCHAR (500) NULL,
[wound_timeReal] DATETIME NULL,
[wound_timeGiven] DATETIME NULL,
[casenumber] INT NULL,
[username] VARCHAR (50) NULL,
[infectionstate] VARCHAR (50) NULL,
PRIMARY KEY CLUSTERED ([wound_id] ASC)
);
Table wound_progress:
CREATE TABLE [dbo].[epadoc_mod_wound_progress] (
[progress_id] INT IDENTITY (1, 1) NOT NULL,
[wound_length] INT NULL,
[wound_width] INT NULL,
[wound_depth] INT NULL,
[wound_surrounding] VARCHAR (500) NULL,
[wound_consistence] VARCHAR (500) NULL,
[wound_state] VARCHAR (200) NULL,
[wound_painscale] INT NULL,
[wound_itch] INT NULL,
[wound_id] INT NULL,
PRIMARY KEY CLUSTERED ([progress_id] ASC),
CONSTRAINT [FK_epadoc_mod_wound_progress_fk] FOREIGN KEY ([wound_id]) REFERENCES [dbo].[epadoc_mod_wound_details] ([wound_id]) ON DELETE CASCADE
);
Then I wrote a SELECT-Query to show all wounds for specific case number which are documented for the patient:
SELECT DISTINCT
dbo.epadoc_mod_wound_details.wound_id, dbo.epadoc_mod_wound_details.casenumber, dbo.epadoc_mod_wound_details.wound_type, dbo.epadoc_mod_wound_progress.progress_id, dbo.epadoc_mod_wound_details.wound_comments, dbo.epadoc_mod_wound_details.wound_timeReal, dbo.epadoc_mod_wound_details.username
FROM dbo.epadoc_mod_wound_details LEFT JOIN
dbo.epadoc_mod_wound_progress
ON dbo.epadoc_mod_wound_details.wound_id = dbo.epadoc_mod_wound_progress.wound_id
WHERE dbo.epadoc_mod_wound_details.casenumber = #casenr;
This is working fine though, but the problem is that ALL wound progresses are shown in the GridView, here is an example so you can see what I mean:
What I want to do is just show the latest progress of one wound, so for the above example just show the last entry with progressID 65:
33 65 1111111 Dekubitus
34 .. ....... .........
The SELECT DISTINCT approach didn't work and I also tried with MAX(progressID) but I always seem to get errors. I think I have to do something with ORDER BY or a second SELECT-Query before the JOIN.
Thanks for any advice!

You should use GROUP BY combined with MAX in your query.
SELECT
dbo.epadoc_mod_wound_details.wound_id,
dbo.epadoc_mod_wound_details.casenumber,
dbo.epadoc_mod_wound_details.wound_type,
MAX(dbo.epadoc_mod_wound_progress.progress_id) AS progress_id,
dbo.epadoc_mod_wound_details.wound_comments,
dbo.epadoc_mod_wound_details.wound_timeReal,
dbo.epadoc_mod_wound_details.username
FROM
dbo.epadoc_mod_wound_details
LEFT JOIN
dbo.epadoc_mod_wound_progress ON
dbo.epadoc_mod_wound_details.wound_id = dbo.epadoc_mod_wound_progress.wound_id
GROUP BY
dbo.epadoc_mod_wound_details.wound_id,
dbo.epadoc_mod_wound_details.casenumber,
dbo.epadoc_mod_wound_details.wound_type,
dbo.epadoc_mod_wound_details.wound_comments,
dbo.epadoc_mod_wound_details.wound_timeReal,
dbo.epadoc_mod_wound_details.username;

Since you only want the progress_id, The easies way to do it is using a correlated subquery:
SELECT wound_id,
casenumber,
wound_type,
(
SELECT TOP 1 progress_id
FROM dbo.epadoc_mod_wound_progress AS WP
WHERE WP.wound_id = WD.wound_id
ORDER BY progress_id
) As progress_id,
wound_comments,
wound_timeReal,
username
FROM dbo.epadoc_mod_wound_details As WD
WHERE casenumber = #casenr;

I understand you need each record of "epadoc_mod_wound_details" with the latest record of "epadoc_mod_wound_progress".
You can try this:
select wound.wound_id, wound.casenumber, wound.wound_type,
wound.wound_comments, wound.wound_timeReal, wound.username, MAX(progress_id)
from epadoc_mod_wound_details wound
left join epadoc_mod_wound_progress progress on wound.wound_id = progress.wound_id
where wound.casenumber = ''
group by wound.wound_id, wound.casenumber, wound.wound_type,
wound.wound_comments, wound.wound_timeReal, wound.username

Fast Way to Replace Names with Ids in Datatable?

I have a very large CSV file I have to load on a regular basis that contains time series data. Examples of the headers are below:
| SiteName | Company | Date | ResponseTime | Clicks |
This data comes from a service external to the uploader. SiteName and Company are both string fields. In the database these are normalized. There is a Site table and a Company table:
CREATE TABLE [dbo].[Site] (
[Id] INT NOT NULL IDENTITY(1, 1) PRIMARY KEY,
[Name] NVARCHAR(MAX) NOT NULL
)
CREATE TABLE [dbo].[Company] (
[Id] INT NOT NULL IDENTITY(1, 1) PRIMARY KEY,
[Name] NVARCHAR(MAX) NOT NULL
)
As well as the data table.
CREATE TABLE [dbo].[SiteStatistics] (
[Id] INT NOT NULL IDENTITY(1, 1) PRIMARY KEY,
[CompanyId] INT NOT NULL,
[SiteId] INT NOT NULL,
[DataTime] DATETIME NOT NULL,
CONSTRAINT [SiteStatisticsToSite_FK] FOREIGN KEY ([SiteId]) REFERENCES [Site]([Id]),
CONSTRAINT [SiteStatisticsToCompany_FK] FOREIGN KEY ([CompanyId]) REFERENCES [Company]([Id])
)
At around 2 million rows in the CSV file any sort of IO-bound iteration isn't going to work. I need this done in minutes, not days.
My initial thought is that I could pre-load Site and Company into DataTables. I already have the CSV loaded into a datatable in the format that matches the CSV columns. I need to now replace every SiteName with the Id field of Site and every Company with the Id field of Company. What is the quickest, most efficient way to handle this?

If you go with Pre-Loading the Sites and Company's you can get the distinct values using code:
DataView view = new DataView(table);
DataTable distinctCompanyValues = view.ToTable(true, "Company")
DataView view = new DataView(table);
DataTable distinctSiteValues = view.ToTable(true, "Site")
Then load those two DataTables into their SQL Tables using Sql-Bulk-Copy.
Next dump all the data in:
CREATE TABLE [dbo].[SiteStatistics] (
[Id] INT NOT NULL IDENTITY(1, 1) PRIMARY KEY,
[CompanyId] INT DEFAULT 0,
[SiteId] INT DEFAULT 0,
[Company] NVARCHAR(MAX) NOT NULL,
[Site] NVARCHAR(MAX) NOT NULL,
[DataTime] DATETIME NOT NULL
)
Then do an UPDATE to set the Referential Integrity fields:
UPDATE [SiteStatistics] ss SET
[CompanyId] = (SELECT Id FROM [Company] c Where ss.[Company] = c.Name),
[SiteId] = (SELECT Id FROM [Site] s Where ss.[Site] = s.Name)
Add the Foreign Key constraints:
ALTER TABLE [SiteStatistics] ADD CONSTRAINT [SiteStatisticsToSite_FK] FOREIGN KEY ([SiteId]) REFERENCES [Site]([Id])
ALTER TABLE [SiteStatistics] ADD CONSTRAINT [SiteStatisticsToCompany_FK] FOREIGN KEY ([CompanyId]) REFERENCES [Company]([Id])
Finally delete the Site & Company name fields from SiteStatistics:
ALTER TABLE [SiteStatistics] DROP COLUMN [Company];
ALTER TABLE [SiteStatistics] DROP COLUMN [Site];

My "data default (getdate())", it doesn't work

I'm trying to insert in my SQL Server table the current date.
My table includes 3 files:
CREATE TABLE [dbo].[MyTable]
(
[Id] INT IDENTITY (1, 1) NOT NULL,
[Name] NVARCHAR (50) NOT NULL,
[Date] DATE
CONSTRAINT [DF_MyTable_Date] DEFAULT (getdate()) NOT NULL,
CONSTRAINT [PK_MyTable] PRIMARY KEY CLUSTERED ([Id] ASC)
)
When a new user wants to register in the system, he has only to insert his name.
In my table, the Id is generated automatically and the date too, but the date shows 01/01/0001 instead of the current day.
Where is the mistake?

if you create a datetime variable in C# like
var today_date = new DateTime();
and do a Console.WriteLine(today_date); u can see it print 0001-01-01
So this is default value of null..
Use DBNull.Value to insert a SQL NULL from C# and check the result

(Your_Date_Column) Make it Null / Not Null and give default value GetDate() but still it will not work. You have to create a trigger like this,
CREATE TRIGGER [dbo].[Trigger_Date] ON [dbo].[TableName] FOR INSERT AS BEGIN
Declare #Id int
set #Id = (select Id from inserted)
Update [dbo].[TableName]
Set Your_Date_Column = GetDate()
Where Id = #Id
END

Functions and triggers are not required. Just set a column with type Date or DateTime to NOT NULL DEFAULT CURRENT_TIMESTAMP.
Updated example code from the question:
CREATE TABLE [dbo].[MyTable]
(
[Id] INT IDENTITY (1, 1) NOT NULL,
[Name] NVARCHAR (50) NOT NULL,
[Date] DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP
CONSTRAINT [PK_MyTable] PRIMARY KEY CLUSTERED ([Id] ASC)
)

How to get column definition from query result

I need a way to get column definition from query result. Right now I'm using SQL Server 2012.
Here is the example scenario, I have two tables which are Event and Attendant whose definitions are below :
CREATE TABLE [dbo].[Event] (
[Id] INT NOT NULL,
[Name] NVARCHAR (50) NULL,
[Description] NVARCHAR (50) NULL,
[StartDate] DATETIME NULL,
[EndDate] DATETIME NULL,
PRIMARY KEY CLUSTERED ([Id] ASC)
);
CREATE TABLE [dbo].[Attendant] (
[Id] INT NOT NULL,
[EventId] INT NOT NULL,
[Name] NVARCHAR (50) NULL,
[Company] NVARCHAR (50) NULL
PRIMARY KEY CLUSTERED ([Id] ASC)
);
And then I have query such as :
SELECT Event.Name as EventName, Attendant.Name as GuestName
FROM Event
INNER JOIN Attendant ON Event.Id = Attendant.EventId
How Can I get the column definition for above example query result? My objective is to generate poco class to represent each record of any query result using c#.

you can use sp_columns sproc to retrieve information about the column definition of a specified table ... like this:
exec sp_columns Attendant

Use sp_columns, it returns column information for the specified objects(tables).
