![]() The only drawback is that the conversion only supports up to millisecond precision, but for most uses cases this is likely not a problem. Here's how I've implemented it in my database context class: Luckily, aptly named user bugproof on GitHub posted a great snippet that attaches a built-in converter for all properties in your database model. While you can work around that with some conversion via an EntityMaterializerSource, this feels awkward and error prone. Even if you're storing only UTC dates, while ensuring you're never making an error anywhere you touch dates, Entity Framework will always return a DateTimeKind.Unspecified when retrieving values from the database. The recommendation to switch to a supported type is great, but what to use? Falling back to regular DateTime, you'll lose the time zone information. Tried also order by 'when' instead of order by datetime ('when'). Also changing desc to asc gives exactly the same results. But it does not return rows ordered by 'when' in reversed order. The error message is pretty clear - SQLite with Entity Framework Core 3.0 does no longer support some operations when using DateTimeOffset properties in database models, as specified in the official Microsoft Guidelines on limitations with SQLite. I tried to view rows ordered by date: sqlite3 -line money.db 'select from money order by datetime ('when') desc limit 5'. Convert the values to a supported type or use LINQ to Objects to order the results. Third, the localtime modifier instructs the function to return the local time. Second, the -1 day modifier is applied to the current date-time that results in the current time of yesterday. System.NotSupportedException : SQLite cannot order by expressions of type 'DateTimeOffset'. In this statement: First, the now time string returns the current date and time. The DateTimeTz type therefore behaves like the DateTime type. all () Fatman13 commented Same problem here. Sqlite does not support saving timezones or offsets. In the process of migrating Dangl.Identity over to the new version, I discovered that some integration tests failed with this message: Download ZIP SQLAlchemy: filter by date for an datetime field (does not work with SQLite, with PostgreSQL it works fine) Raw SQLAlchemycast.py from datetime import date from sqlalchemy import cast, DATE Match. ![]() Recently, ASP.NET Core 3.0 was released, along with all it's supporting libraries like Entity Framework Core. ![]()
