  1. J'ai une base de données SQLite avec une table d' event composée de quatre colonnes: id (INT), timestamp (TEXT), level (TEXT) et message (TEXT). Lorsque je relis les événements, je souhaite convertir les valeurs de level valeurs d'énumération LogLevel correspondantes. Les valeurs de texte sont les mêmes que les noms des membres enum.
  2. Array(ENUM) Its only supported with PostgreSQL. Array(Enum) type require special treatment. Whenever Sequelize will talk to database it has to typecast Array values with ENUM name. So this enum name must follow this pattern enum_<table_name>_<col_name>. If you are using sync then correct name will automatically be generated. Range type
  3. enum (not string) may be appropriate in some circumstances (for example a small or simple application where the approach is code first.) In this case (if your ORM doesn't do it for you) take a look to Jim's answer, I think it might be the way to go. Integers (enums) have some benefits: They're small and index friendly. They're case insensitive. City/country can change name. And some drawbacks.
  4. ed by its container - the particular column in which the value is stored. SQLite uses a more general dynamic type system. In SQLite, the datatype of a value is associated with the value itself, not with.

SQLite is a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine. SQLite is the most used database engine in the world. SQLite is built into all mobile phones and most computers and comes bundled inside countless other applications that people use every day In some cases a database is nothing more than a file format for an application (SQLite databases can often be used in this regard). In this case bit duplicating the enum definition as a table can often be fine and may make more sense. However as soon as you want to consider the possibility of having multiple applications accessing the database, then a table for the enum makes a lot of sense. The Enum object's GetNames member, for example, will give you a collection of the string representations of all the members of the enumeration (in Visual Basic, you must enclose the Enum object's name in square brackets to use it). This code, for example, will load a listbox with the names from the CreditStatusTypes Enum, for example: Me.ListBox1.DataSource = (From li In [Enum].GetNames. sqliteにはenumはありませんが、同様の動作を再現することは可能です。 以下の記事ではenumを実現するためにトリガを使っていますが、いくらなんでも手間がかかり過ぎです。 sqliteでenum型. 他にやり方はないかと考えてみるとcheck制約で入力値を制限できることに気づきました。 sqlite. create table if.
