CSharpDB.Primitives

Shared types, schema definitions, and error codes for the CSharpDB embedded database engine.

Overview

CSharpDB.Primitives is the low-level foundation package for CSharpDB. It defines the database type system, schema model, and error codes used by higher-level CSharpDB packages.

If you are building an application, prefer the top-level package:

dotnet add package CSharpDB

Key Types

Type	Description
`DbType`	Six compact physical value carriers: `Null`, `Integer`, `Real`, `Text`, `Blob`, `Decimal`
`DbValue`	Discriminated-union struct representing a single database value with comparison, equality, and truthiness semantics
`TableSchema`	Table structure definition including columns, primary key, and qualified mappings for JOINs
`ColumnDefinition`	Column metadata: name, type, nullability, primary key flag, and identity flag
`IndexSchema`	Index metadata: name, table, columns, uniqueness
`TriggerSchema`	Trigger metadata: name, table, timing, event, and body SQL
`DbFunctionRegistry`	Host-registered trusted scalar functions for SQL and expression surfaces
`DbCommandRegistry`	Host-registered trusted commands for Forms, Reports, and pipeline automation surfaces
`DbCommandOptions`	Command description plus optional timeout and long-running metadata
`CSharpDbException`	Typed exception with `ErrorCode` covering 15+ error conditions

Logical SQL declarations retain a separate SqlTypeDescriptor over these six physical carriers. For example, BOOLEAN, INTEGER, and BIGINT share the Integer carrier while preserving distinct coercion and materialization rules. See the SQL data type reference for the complete declaration matrix.

Usage

using CSharpDB.Primitives;

// Create typed values
var id = DbValue.FromInteger(42);
var name = DbValue.FromText("Alice");
var balance = DbValue.FromDecimal(100.50m);
var empty = DbValue.Null;

// Compare values
bool isPositive = DbValue.Compare(balance, DbValue.FromDecimal(0m)) > 0;

// Define a schema
var schema = new TableSchema
{
    TableName = "users",
    Columns =
    [
        new ColumnDefinition { Name = "id", Type = DbType.Integer, IsPrimaryKey = true },
        new ColumnDefinition { Name = "name", Type = DbType.Text },
        new ColumnDefinition { Name = "email", Type = DbType.Text, Nullable = true }
    ]
};
