You can workaround some of these limitations by manually writing code in your migrations to perform a rebuild. If a database artifact isn't part of the model-for example, if it was created manually inside a migration-then a NotSupportedException is still thrown. Rebuilds are only possible for database artifacts that are part of your EF Core model. If you attempt to apply one of the unsupported operations to a SQLite database then a NotSupportedException will be thrown.Ī rebuild will be attempted in order to perform certain operations. The SQLite database engine does not support a number of schema operations that are supported by the majority of other relational databases. You can use a value converter to continue using decimal in your classes. If you don't need that level of precision, however, we recommend using double instead. The Decimal type provides a high level of precision. When handling multiple time zones, we recommend converting the values to UTC before saving and then converting back to the appropriate time zone. Instead of DateTimeOffset, we recommend using DateTime values. Other operations, however, like comparison and ordering will require evaluation on the client. EF Core can read and write values of these types, and querying for equality ( where e.Property = value) is also supported. SQLite doesn't natively support the following data types. A couple of these concepts are not supported by the SQLite provider. The common relational library (shared by Entity Framework relational database providers) defines APIs for modelling concepts that are common to most relational database engines. Most of these limitations are a result of limitations in the underlying SQLite database engine and are not specific to EF. Where can I get such a database file to start using RoundCube? The SQL dump is quite useless to me if the installer is broken and I don't have the tool to do it on my own.The SQLite provider has a number of migrations limitations. Doesn't PHP 5 always come with SQLite 3 only? What's the problem with version 3, which is current for ages by now and working for all my other projects (web and desktop)?Įdit 2: I don't have any "sqlite" binary on that web server machine (running Linux). The more elegant would be to only write page content after starting the session.Įdit: I've read the INSTALL file and it says that PHP 5 and SQLite 2 are required. How is that supposed to work? The easiest solution would be to put a at the very beginning of every page that starts a PHP session. Starting a PHP session sends an HTTP header, but those cannot be sent after HTTP body has started. I cannot imagine how you didn't notice that during the very first development steps. All previous checks of the RC installer were passed.Īnother thing is that the PHP files of RC are written in a way that they can never work without a problem: You start HTML output first and then start the PHP session. Running PHP 5.2.5 with SQLite support enabled and working fine for several other applications. Make sure that the configured database extists and that the user as write privileges Please try to inizialize the database manually as described in the INSTALL guide.
