StringThing.Npgsql.Dapper

Dapper result mapping for StringThing.Npgsql. Injection-safe interpolated SQL on the input side, Dapper mapping on the output side.

Install

dotnet add package StringThing.Npgsql.Dapper

Quick start

var userId = 42;
var user = await connection.QueryStringSingleAsync<User>(
    $"SELECT id, name, email FROM users WHERE id = {userId}",
    cancellationToken);

Available methods

All methods are extension methods on NpgsqlConnection:

Method Returns
QueryStringAsync<T> Task<List<T>>
QueryStringFirstAsync<T> Task<T>
QueryStringFirstOrDefaultAsync<T> Task<T?>
QueryStringSingleAsync<T> Task<T>
QueryStringSingleOrDefaultAsync<T> Task<T?>
ExecuteStringAsync Task<int>
ExecuteStringScalarAsync<T> Task<T?>

Synchronous variants are also available (without the Async suffix).

Why "String" in the method names?

The method names include String to avoid collision with Dapper's own extension methods. If both were named QueryAsync, a using change could silently switch from the safe StringThing path to Dapper's string-based path — defeating the injection safety guarantee.

QueryStringSingleAsync is unambiguous: it's the StringThing version, always.

DDL and static SQL

For setup queries with no parameters, use $"..." without interpolation:

await connection.ExecuteStringAsync(
    $"""
    CREATE TABLE IF NOT EXISTS users (
        id integer PRIMARY KEY,
        name text NOT NULL
    )
    """,
    cancellationToken);
