Based on the code snippet you provided it looks like you are trying to update the LikeCount field of a quicknote object using Entity Framework Core. However Entity Framework Core's ExecuteUpdate method does not have a direct equivalent in the EF Core library which could be the reason for the syntax error. To update the LikeCount field in the database you can follow a different approach using the SaveChanges method of your DbContext after modifying the entity. Here's how you can do it: Assuming you have a DbContext class named YourDbContext  and the entity class is named Quicknote  the correct way to update the LikeCount field is as follows: // Assuming you have a YourDbContext instance named dbContext var quicknote = _context.quicknotes.FirstOrDefault(x => x.Id == request.id); if (quicknote != null) { quicknote.LikeCount++; // Increment the LikeCount by 1 dbContext.SaveChanges(); // Save the changes to the database } In this code we first retrieve the quicknote entity with the specified Id using FirstOrDefault . Then if the quicknote is found (i.e. not null) we increment its LikeCount property and call SaveChanges on the DbContext to persist the changes to the database.
