CSharpDB.Primitives

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

NuGet .NET 10 Release License: MIT

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 Enum of supported database types: Null, Integer, Real, Text, Blob
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

Usage

using CSharpDB.Primitives;

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

// Compare values
bool isPositive = DbValue.Compare(balance, DbValue.FromReal(0)) > 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 }
    ]
};
