Explanation

  1. Setup: Initializes the database and configures Vitorm.
  2. Create Table: Drops and recreates the User table.
  3. Insert Records: Adds single and multiple user records.
  4. Query Records: Retrieves user records using various querying methods.
  5. Update Records: Updates single and multiple user records.
  6. Delete Records: Deletes single and multiple user records.
  7. Join Queries: Performs a join operation between user and father records.
  8. Transactions: Demonstrates nested transactions and rollback/commit operations.
  9. Database Functions: Uses custom database functions in queries.

Vitorm.Data Documentation

Vitorm.Data is a static class that allows you to use Vitorm without explicitly creating or disposing of a DbContext.

Installation

Before using Vitorm.Data, install the necessary package:

dotnet add package Vitorm.Data
dotnet add package Vitorm.File

Config settings

// appsettings.json
{
  "Vitorm": {
    "Data": [
      {
        "provider": "File",
        "mode": "TableToFile",
        "namespace": "App",
        "connectionString": "Data/db_orm"
      }
    ]
  }
}

Minimum viable demo

After configuring the appsettings.json file, you can directly perform queries without any additional configuration or initialization, Vitorm.Data is that easy to use.
code address: Program_Min.cs

using Vitorm;
namespace App
{
    public class Program_Min
    {
        static void Main2(string[] args)
        {
            //  Query Records
            var user = Data.Get<User>(1);
            var users = Data.Query<User>().Where(u => u.name.Contains("li")).ToList();
        }

        // Entity Definition
        [System.ComponentModel.DataAnnotations.Schema.Table("User")]
        public class User
        {
            [System.ComponentModel.DataAnnotations.Key]
            public int id { get; set; }
            public string name { get; set; }
