CH.Toolkit.Types

Immutable record-based type system representing 40+ ClickHouse data types, with parsing and CLR mapping.

Key Types

  • ClickHouseType -- abstract base record; all types derive from this and implement ToSql()
  • Scalars: ChString, ChInt32, ChUInt64, ChFloat64, ChBool, ChDate, ChDateTime, ChDateTime64, ChDecimal, ChUuid, ChIPv4, ChIPv6
  • Compound: ChNullable, ChArray, ChMap, ChTuple, ChLowCardinality, ChNested
  • Enums: ChEnum8, ChEnum16
  • Geo: ChPoint, ChRing, ChPolygon, ChMultiPolygon
  • Special: ChJson, ChFixedString, ChSimpleAggregateFunction, ChAggregateFunction
  • ClickHouseTypeParser -- parses ClickHouse type strings (e.g. "Nullable(String)") into ClickHouseType records
  • ClrTypeMapper -- bidirectional mapping between .NET CLR types and ClickHouse types

Dependencies

None.

Usage

using CH.Toolkit.Types;

// Create types directly
var col = new ChNullable(new ChString());
Console.WriteLine(col.ToSql()); // "Nullable(String)"

// Parse from a ClickHouse type string
var parsed = ClickHouseTypeParser.Parse("Array(DateTime64(3, 'UTC'))");
// parsed is ChArray { Element = ChDateTime64 { Precision = 3, TimeZone = "UTC" } }

// Map from CLR type
var mapped = ClrTypeMapper.FromClr(typeof(int?));
// mapped is ChNullable { Inner = ChInt32 }
