PetaPoco is a tiny & fast micro-ORM for .NET
- Like Dapper, it's fast because it uses dynamic method generation (MSIL) to assign column values to properties
- Like Massive, it now also supports dynamic Expandos too
- Like ActiveRecord, it supports a close relationship between object and database table
- Like SubSonic, it supports generation of poco classes with T4 templates (V5 only)
- Like Massive it's available as single file that you easily add to any project or complied. (V5 only)
Features at a Glance
- Tiny, and absolutely no dependencies!
- Asychronise or synchronise, the choice is yours. (aka async) (V6)
- Works with strictly undecorated POCOs, or attributed almost-POCOs.
- Easy to configure and includes fluent configuration out of the box.
- Helper methods for Insert/Delete/Update/Save and IsNew
- Paged requests automatically work out total record count and fetch a specific page.
- Easy transaction support.
- Better parameter replacement support, including grabbing named parameters from object properties.
- Great performance by eliminating Linq and fast property assignment with DynamicMethod generation.
- The query language is good ole SQL.
- Includes a low friction SQL builder class that makes writing inline SQL much easier.
- Includes T4 templates to automatically generate POCO classes for you. (V5)
- Hooks for logging exceptions, installing value converters and mapping columns to properties without attributes.
- Works with SQL Server, SQL Server CE, MS Access, SQLite, MySQL, MariaDB, Firebird, and PostgreSQL. (Oracle supported but does not have integration tests).
- Works under Net Standard 2.0, .NET 4.0/4.5+ or Mono 2.8 and later.
- Has Xunit unit tests.
- Has supported DBs integration tests.
- OpenSource (MIT License or Apache 2.0)
Super easy use and configuration
Save an entity
db.Save(article);
db.Save(new Article { Title = "Super easy to use PetaPoco" });
db.Save("Articles", "Id", { Title = "Super easy to use PetaPoco", Id = Guid.New() });
Get an entity
var article = db.Single<Article>(123);
var article = db.Single<Article>("WHERE ArticleKey = @0", "ART-123");
Delete an entity
db.Delete(article);
db.Delete<Article>(123);
db.Delete("Articles", "Id", 123);
db.Delete("Articles", "ArticleKey", "ART-123");
Plus much much more.
