I am working on live support project for a web site. I just wrote the frontend and I created the table that I need in SQL Server and then I made a connection between SQL Server and my ASP.NET MVC project.
I watched many videos and I didn't get the part which I will start get the data from the models which are created when I made the connection I talked about.
To be clear: I wrote two Divs in web page one for the sender and one for the receiver and I give messages a variable called ̰"destination" in DB so if the value is 0 it will be insert the text in sender's div and if the value is 1 it will be insert the text in receiver's div.
The problem that I know the logic but I don't know how to apply it. Please can anyone help me and tell me how to do it? Or what is the Technique that I should work with?
You should start looking into Entity Framework to get the data from the database. I think for now you should use Database First approach which is very easy as compared to Code first approach.
To start with Database first just add new item and select ADO.NET Entity Model . This will launch the wizard where you can select EF designer from database and then you can give the connection string and all the databse you want to use
Refer below link for explanation.

I am using Ionic 5 for app development. within Ionic framework, I have created SQLite database using Ionic SQLite Plugin where I am saving my app logs.
Further when building the app through Android Studio , I want to insert the crash logs which I can only access via Android Studio into the same Database file which is already created in my File explorer > data > data > app_package_file > database file .
To do this I have tried to create a SQLite database with same database name and same table name in Android Studio using this documentation.
to add values into the database file I have added the below sort of code in Android Studio.
val values = ContentValues().apply {
put(FeedEntry.COLUMN_NAME_TITLE, date)
put(FeedEntry.COLUMN_NAME_SUBTITLE, 'logs_data')
}
With this approach ,the existing database file do got updated , but when I download the database file from file explorer, I get only a blank file, to which I assume that my newly created SQLite db file has overriden the old one.
I know, my approach was not correct, but Is there any other way to achieve this requirement .
PS- This is my first question on SO, If anyone feel any improvement in the Question , please suggest an edit.
Thanks in advance ,for the help.
Instead of calling contentvalues() , and calling put function for each and every INSERT.
You can just use
db.execSQL("INSERT INTO tablename VALUES('x','y','z').
into your MainActivity.java.
I have problem with delphi application which is running on database using BDE components. Application with GUI shows results but do not show SQL which is generated to get information from database. I need to find some of the results in tables, but I do not know data structure of the DB and I have no idea in which table I should look in. Any ideas how to extract that SQL that is generated from application as query to DB?
There is any possibility to store some links to a location from a server in a in a SQL Server 2008 database?
I have some rows in a table and for each of them I have a pdf.
I want to create a column in which to store the link to this PDF which will be placed on a server location.
My question is how could I make this link clickable (active), there is any specific type column for links?
Thank you!
In the database, just simply store the URL as a string - varchar(200) or whatever works for you.
Making that URL clickable is the job of a front-end application, e.g. your ASP.NET or PHP or whatever app that displays that data.
This is not something SQL Server should be concerned about -
So no - there is no specific datatype to make a column clickable in SQL Server directly.
Not a feature directly in SQL.
On the front end this would be a hypelink.
It depends on the front end
ASP.NET DataGrid:
HyperLinkColumn Class
In WPF:
DataGridHyperlinkColumn Class
In SQL you would just store the link location as a char or varchar.
How can I connect my sencha app to oracle db.
Any ideas??
I am trying to make a customer book with 2 columns.
values will be shown in the mobile app.
Ok #Shaleen,
Can you connect to database with Java or C# or with whatever you want.
The information you get from the database you can convert to JSON.
With Sencha can you get JSON file with information available.
Hope these helps. :)
It's simple.
Steps:-
Get the values from the form panel ( assuming you use it) and call an Ext.Ajax.request() on form submission.
Provide the url of the php path ( in case you're using PHP at the backend) and make all connection inside PHP file to db, retrieve the values using $_POST[] and insert them into the db.
