StringThing.Npgsql

Injection-safe interpolated SQL for PostgreSQL, built on Npgsql. Part of StringThing.

Install

dotnet add package StringThing.Npgsql

Quick start

var userId = 42;
PostgresSql stmt = $"SELECT name FROM users WHERE id = {userId}";
await using var command = stmt.ToCommand(dataSource);

Supported types

All standard .NET types (int, string, DateTime, Guid, etc.) plus Postgres-specific types: NpgsqlPoint, NpgsqlBox, NpgsqlRange<T>, NpgsqlTsVector, NpgsqlTsQuery, IPAddress, and more. See PostgresValue for the full list.

Nullable variants are supported. Reference types (string?, byte[]?, IPAddress?) map to NULL. Value types use PostgresValue?.

Fragments

var minAge = 18;
var status = "active";
PostgresFragment filter = $"age >= {minAge} AND status = {status}";

PostgresSql stmt = $"SELECT * FROM users WHERE {filter}";

Fragments compose. Parameters renumber automatically across fragment boundaries.

Multi-row insert

record InsertUser(int Id, string Name, string? Email) : IPostgresRow
{
    public PostgresFragment RowValues => $"({Id}, {Name}, {Email})";
}

var users = new InsertUser[] { new(1, "alice", "alice@example.com"), new(2, "bob", null) };
PostgresSql stmt = $"INSERT INTO users (id, name, email) VALUES {PostgresSql.InsertRows(users)}";

JSON

Implement IPostgresJson on your types to store them as jsonb. Use your choice of serializer:

record UserData(string Name, int Age) : IPostgresJson
{
    public string ToJson() => $$"""{"name":"{{Name}}","age":{{Age}}}""";
}

PostgresSql stmt = $"INSERT INTO data (payload) VALUES ({userData})";

Unsafe escape hatch

var tableName = Sql.Unsafe("users");
PostgresSql stmt = $"SELECT * FROM {tableName} WHERE id = {userId}";
