When working with Entity Framework Core (EF Core), you might encounter a DbUpdateException while saving changes to a database that has triggers. Hereโ€™s a simple breakdown of what causes the error and how I resolved it.

  1. ๐—ช๐—ต๐—ฎ๐˜ ๐—ถ๐˜€ ๐—ฎ ๐—ง๐—ฟ๐—ถ๐—ด๐—ด๐—ฒ๐—ฟ?

    • A ๐˜๐—ฟ๐—ถ๐—ด๐—ด๐—ฒ๐—ฟ is a special kind of stored procedure in the database that automatically executes when certain events occur (e.g., INSERT, UPDATE, or DELETE).
  2. ๐—ช๐—ต๐˜† ๐˜๐—ต๐—ฒ ๐—˜๐—ฟ๐—ฟ๐—ผ๐—ฟ ๐—›๐—ฎ๐—ฝ๐—ฝ๐—ฒ๐—ป๐˜€:

    • ๐—ง๐—ฟ๐—ถ๐—ด๐—ด๐—ฒ๐—ฟ๐˜€ are used for tasks like logging, validation, or automatic data modification when records are inserted or updated.
    • When EF Core tries to save changes, the triggerโ€™s behavior can interfere with the operation, leading to the DbUpdateException.
  3. ๐—›๐—ผ๐˜„ ๐—œ ๐—™๐—ถ๐˜…๐—ฒ๐—ฑ ๐˜๐—ต๐—ฒ ๐—œ๐˜€๐˜€๐˜‚๐—ฒ:

    • The error was happening because EF Core wasnโ€™t handling the operation properly due to the triggers.
    • ๐—ง๐—ต๐—ฒ ๐˜€๐—ผ๐—น๐˜‚๐˜๐—ถ๐—ผ๐—ป: I switched to using the SaveChangesAsync() method instead of SaveChanges(). The async method better handles the database context and prevents conflicts with database triggers.
  4. ๐—ก๐—ฒ๐˜…๐˜ ๐—ฆ๐˜๐—ฒ๐—ฝ๐˜€:

    • Always ensure your ๐˜๐—ฟ๐—ถ๐—ด๐—ด๐—ฒ๐—ฟ๐˜€ ๐—ฎ๐—ฟ๐—ฒ ๐—ฝ๐—ฟ๐—ผ๐—ฝ๐—ฒ๐—ฟ๐—น๐˜† ๐—ฐ๐—ผ๐—ป๐—ณ๐—ถ๐—ด๐˜‚๐—ฟ๐—ฒ๐—ฑ to work seamlessly with EF Core operations.
    • If triggers require extra data (e.g., user info, timestamps), make sure you provide it before saving.
    • The SaveChangesAsync() method is more suitable when dealing with complex database operations, especially when triggers are involved.

gonna report this post, but not because you did anything wrong, just noticed the url seems to be buggy because of your use of Quotes in the title. That's a bug they need to fix.
You should report it too :)
