It allows any program developed for .Net framework to access a Postgresql database server. It is implemented in 100% C# code. Works with Postgresql 8.4 and above. For previous .npgsql 4.0.10Npgsql has an Entity Framework (EF) Core provider. It behaves like other EF Core providers (e.g. SQL Server), so the general EF Core docs apply here as well. If you're just getting started with EF Core, those docs are the best place to start.

You’ll see how to interact between Postgres and C# using the standard data provider library Npgsql, use it with Dapper, and even with Entity Framework. We’ll go over the basic operations like creating a .

In this article, you learn how to use the .NET Aspire PostgreSQL component. The Aspire.Npgsql library is used to register a NpgsqlDataSource in the DI container for connecting to a PostgreSQL database. It also enables corresponding health checks, .

The Npgsql EF Core provider also supports reverse-engineering a code model from an existing PostgreSQL database ("database-first"). To do so, use dotnet CLI to execute the following: dotnet ef dbcontext scaffold "Host=my_host;Database=my_db;Username=my_user;Password=my_pw" .

It allows you to interact with PostgreSQL via the most widely-used .NET O/RM from Microsoft, and use familiar LINQ syntax to express queries. It's built on top of Npgsql. The provider looks and feels just like any other Entity Framework Core provider. まずやるべき事はNpgsqlのインストールです。 「ツール」-「Nugetパッケージマネージャー」-「ソリューションのNugetパッケージの管理」-「参照」の検索ウインドウで「npgsql」と入力するとおそらく先頭に「Npgsql」が出ると思いますので、それを選択し画面右 .7.0.2 contains 8 fixes, everyone is strongly encouraged to upgrade.

This is possible using a DbConfiguration class. Example use cases: Forcing all returned DateTime and DateTimeOffset values to be in the UTC timezone.

ClearPool (NpgsqlConnection) Clears the connection pool. All idle physical connections in the pool of the given connection are immediately closed, and any busy connections which were opened before Clear Pool (Npgsql Connection) was called will be closed when returned to the pool.DbDataSource. A major improvement in Npgsql 7.0 is Npgsql Data Source, which implements the new DbDataSource abstraction in .NET System.Data. A data source represents your PostgreSQL database, and can hand out connections to it or support direct execution of SQL to it. Instead of directly instantiating an NpgsqlConnection and then .

Npgsql 6.0 introduced some important changes to how timestamps are mapped, see the release notes for more information. Note The recommended way of working with date/time types is the NodaTime plugin : the NodaTime types are much better-designed, avoid the flaws in the built-in BCL types, and are fully supported by Npgsql.Npgsql Notification Event Args. Provides information on a PostgreSQL notification. Notifications are sent when your connection has registered for notifications on a specific channel via the LISTEN command. NOTIFY can be used to generate such notifications, allowing for an inter-connection communication channel.Supported Types and their Mappings. The following lists the built-in mappings when reading and writing CLR types to PostgreSQL types. Note that in addition to the below, enum and composite mappings are documented in a separate page.Note also that several plugins exist to add support for more mappings (e.g. spatial support for PostGIS), these .Version 8.0 also brings support for EF7's JSON columns feature (ToJson), which allows mapping JSON columns via owned entity types. While the Npgsql EF provider has had POCO JSON mapping for a very long time, the full modeling of the new ToJson () allows for a more powerful mapping strategy, with more query and update features.Beyond PostgreSQL, Npgsql provides its own set of diagnostics features for tracing, logging and producing metrics. Tracing and metrics are particularly useful for performance analysis - consider collecting this data continuously on your production platform. These features are documented in the dedicated diagnostics page. 接続文字列の作成. 最初に接続文字列を作成します。. 以下の情報が接続に必要となります。. これらの情報を、以下のような形の文字列とする必要があります。. この後紹介するコードでは、connectionTextが文字列情報を保持します。. “Server=localhost;Port=5432 .Npgsql is the .NET data provider for PostgreSQL.

Running this program outputs the following to the console: info: Npgsql.Command[2001] Command execution completed (duration=16ms): SELECT 1. By default, Npgsql logs command executions at the Information log level, as well as various warnings and errors. To see more detailed logging, increase the log level to Debug or Trace.Npgsql has emitted metrics for several versions, which provided aggregated metrics on various Npgsql interals; for example, it was possible to follow the state of the connection pool, or to track how many commands are being executed per second. Npgsql 8.0 improves on that by switching from the older EventCounter API to the newer System .Text COPY. This mode uses the PostgreSQL text or csv format to transfer data in and out of the database. It is the user's responsibility to format the text or CSV appropriately, Npgsql simply provides a TextReader or Writer. This mode is less efficient than binary copy, and is suitable mainly if you already have the data in a CSV or compatible .
