Attribute-based O/R mapping information

QLimitive performs O/R mapping and generates SQL based on the attributes used in Entity Framework Core.

using System;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;

namespace SampleApp;

[Table("T_People", Schema = "dbo")]
public sealed class Person
    public int Id { get; init; }

    public string LastName { get; init; }

    public string FirstName { get; init; }

    public string FullName => $"{this.LastName} {this.FirstName}";

    public int Age { get; init; }

    public bool HasChildren { get; init; }

    public DateTimeOffset CreatedAt { get; init; }

    public DateTimeOffset ModifiedAt { get; init; }

SQL generation

This library also provides automatic sql generation feature using above meta data. You can get very simple and typical SQL via QueryBuilder class. Of course it's completely type-safe.

// Query records with specified columns that matched specified condition
var sql = QueryBuilder.Select<Person>(DbDialect.SqlServer, x => new { x.LastName, x.Age }).Text;

    [姓] as [LastName],
    [Age] as [Age]
from [dbo].[T_People]
// If wants Where / OrderBy / ThenBy, allows you to write like following
using (var builder = new QueryBuilder<Person>(DbDialect.SqlServer))
    builder.Select(static x => new { x.Id, x.LastName });
    builder.Where(static x => x.LastName == "Suzuki");
    builder.OrderByDescending(static x => x.Age);
    builder.ThenBy(static x => x.ModifiedAt);
    var sql = builder.Build().Text;

    [Id] as [Id],
    [姓] as [Name]
from [dbo].[T_People]
    [姓] = @p1
order by
    [Age] desc,
// Insert record to SQL Server
var sql = QueryBuilder.Insert<Person>(DbDialect.SqlServer, useAmbientValue: true).Text;

insert into [dbo].[T_People]
// Update records with specified columns that matched specified condition
using (var builder = new QueryBuilder<Person>(DbDialect.SqlServer))
    builder.Update(static x => new { x.LastName, x.Age, x.ModifiedAt }, useAmbientValue: true);
    builder.Where(static x => x.Age < 35 || x.LastName == "Suzuki");
    var sql = builder.Build().Text;

update [dbo].[T_People]
    [姓] = @LastName,
    [Age] = @Age,
    [UpdatedAt] = SYSDATETIME()
    [Age] < @p3 or [姓] = @p4

QueryBuilder class also provides some other overload functions and Count / Delete / Truncate methods, and so on.
