Documentation

For configuration documentation, code examples, and other general usage information, see the docs.

Add-ons

PetaPoco.SqlKata lets you use the powerful query builder SqlKata to build SQL queries for PetaPoco.
StaTypPocoQueries.PetaPoco provides the ability to use some simple, strongly typed, Intellisensed LINQ expressions in your queries.
PetaPoco.DBEntityGenerator lets you generate Pocos from your DB (T4 template replacement).

Version 5 - Legacy

Nuget (Single file)	Nuget Core (+t4 templates)	Nuget Core Compiled (dll)

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 a single file that you easily add to any project or complied. (V5 only)

Features at a Glance

Tiny, and absolutely no dependencies!
Asychronous (aka async) or synchronous: the choice is yours. (V6)
Works with strictly undecorated POCOs, or attributed almost-POCOs.
Easy to configure, including fluent configuration out of the box.
Helper methods for Insert/Delete/Update/Save and IsNew
Paged requests automatically work out the 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 is supported but does not have integration tests).
Works under Net Standard 2.0, .NET 4.0/4.5+ or Mono 2.8 and later.

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.
