CH.Native.Dapper

Dapper integration for CH.Native, the high-performance .NET client for ClickHouse using the native binary TCP protocol.

By default, Dapper expands array parameters (int[], string[], etc.) into SQL tuples — fine for most databases, wrong for ClickHouse, where you usually want them bound as Array(T) on the wire. This package registers Dapper type handlers that send arrays as native ClickHouse arrays.

Install

dotnet add package CH.Native.Dapper

Usage

Call Register() once during startup:

using CH.Native.Dapper;

ClickHouseDapperIntegration.Register();

Then use array parameters as you would expect:

using var connection = new ClickHouseDbConnection("Host=localhost;Database=default");
await connection.OpenAsync();

var ids = new[] { 1, 2, 3, 4, 5 };
var rows = await connection.QueryAsync<MyRow>(
    "SELECT * FROM events WHERE id IN (SELECT arrayJoin(@ids))",
    new { ids });

Without this package, Dapper would rewrite @ids into (@ids1, @ids2, ...). With it, @ids is sent as a single Array(Int32) parameter.

Registered types

bool[], sbyte[], short[], int[], long[], byte[], ushort[], uint[], ulong[], float[], double[], decimal[], string[], Guid[], DateTime[], DateTimeOffset[], DateOnly[].

Register() is idempotent — repeated calls are no-ops.
