EasyReasy.Database.Mapping.Npgsql

NuGet

Npgsql-specific enum handler for EasyReasy.Database.Mapping. Automatically sets NpgsqlParameter.DataTypeName on enum parameters, eliminating the need for ::pg_type casts in SQL queries.

Installation

dotnet add package EasyReasy.Database.Mapping.Npgsql

Usage

With the base DbNameEnumHandler<T>, you need explicit casts in your SQL:

// Without this package — requires ::mapping_test_status cast
TypeHandlerRegistry.AddTypeHandler(new DbNameEnumHandler<TestStatus>());

await connection.ExecuteAsync(
    "INSERT INTO users (name, status) VALUES (@name, @status::user_status)",
    new { name = "Alice", status = UserStatus.Active });

With NpgsqlDbNameEnumHandler<T>, the cast is handled automatically:

// With this package — no cast needed
TypeHandlerRegistry.AddTypeHandler(new NpgsqlDbNameEnumHandler<UserStatus>("user_status"));

await connection.ExecuteAsync(
    "INSERT INTO users (name, status) VALUES (@name, @status)",
    new { name = "Alice", status = UserStatus.Active });

When using PostgreSQL enum types, you need two registrations: Npgsql's MapEnum (so Npgsql recognizes the type) and a NpgsqlDbNameEnumHandler (so EasyReasy maps values via [DbName] attributes). The MapDbNameEnum<T>() extension method on NpgsqlDataSourceBuilder does both in one call, reading the type name from a [DbEnum] attribute on the enum:

[DbEnum("user_status")]
public enum UserStatus
{
    [DbName("active")]
    Active,

    [DbName("inactive")]
    Inactive
}

// One call registers both MapEnum and NpgsqlDbNameEnumHandler
IDataSourceFactory factory = new NpgsqlDataSourceFactory(builder =>
{
    builder.MapDbNameEnum<UserStatus>();
});

This is the recommended approach because:

  • The database type name is defined once on the enum, not duplicated across registration calls
  • It ensures both MapEnum and the type handler are always registered together — forgetting either one causes hard-to-debug errors
  • MapEnum is required by Npgsql 10+ for custom enum types; MapDbNameEnum handles this automatically
