I’m trying to convert this query to LINQ, but I’m not getting the value of the subquery
The tables i want are looking like this…
I clonned old respository of an ASP.NET MVC project. It uses MySql as its server. When I tried to run the project, it shows NullReference Error when trying to connect to database.
I’m using .Net Framework 4.5 and I get the following error:
I’m trying to set up a database migration job for dotnet entity framework.
It seems that I cannot connect to mysql database service from kubernetes job, but I can connect from my desktop when I forward ports.
I need to select from a MySQL database using Entity Framework Core (with Pomelo provider), 10 random records where their IDs are between 1 to 600. Is it possible?
In one of my DB models I have a property with a custom type (
Dictionary<string, string>), which is automatically converted to/from JSON with a custom converter, and is stored as a
text field in the database. I would like to be able to use MySQL’s
LIKE comparer to search for a string within this JSON field, but I am getting an exception. I don’t care about the JSON’s structure, I’m fine with treating it as a simple text field and searching in it that way.
So I made a windows form which has a search textbox that will return the parts of string that you have entered in the datagrid. However, in my attempt to code this following event. The datagrid shows boolean instead.
I have this query in SQL, and I want it to implement it in LINQ using Entity Framework, but how can I apply multiple tables left outer joins?
