Some open source projects that use FreeSql:



🚀 Quick start

dotnet add package FreeSql.Provider.Sqlite

  1. static IFreeSql fsql = new FreeSql.FreeSqlBuilder()
  2. .UseConnectionString(FreeSql.DataType.Sqlite, @"Data Source=document.db")
  3. .UseAutoSyncStructure(true) //automatically synchronize the entity structure to the database
  4. .Build(); //be sure to define as singleton mode
  5. class Song {
  6. [Column(IsIdentity = true)]
  7. public int Id { get; set; }
  8. public string Title { get; set; }
  9. public string Url { get; set; }
  10. public DateTime CreateTime { get; set; }
  11. public ICollection<Tag> Tags { get; set; }
  12. }
  13. class Song_tag {
  14. public int Song_id { get; set; }
  15. public Song Song { get; set; }
  16. public int Tag_id { get; set; }
  17. public Tag Tag { get; set; }
  18. }
  19. class Tag {
  20. [Column(IsIdentity = true)]
  21. public int Id { get; set; }
  22. public string Name { get; set; }
  23. public int? Parent_id { get; set; }
  24. public Tag Parent { get; set; }
  25. public ICollection<Song> Songs { get; set; }
  26. public ICollection<Tag> Tags { get; set; }
  27. }

🔎 Query

  1. //OneToOne、ManyToOne
  2. fsql.Select<Tag>().Where(a => a.Parent.Parent.Name == "English").ToList();
  3. //OneToMany
  4. fsql.Select<Tag>().IncludeMany(a => a.Tags, then => then.Where(sub => sub.Name == "foo")).ToList();
  5. //ManyToMany
  6. fsql.Select<Song>()
  7. .IncludeMany(a => a.Tags, then => then.Where(sub => sub.Name == "foo"))
  8. .Where(s => s.Tags.Any(t => t.Name == "Chinese"))
  9. .ToList();
  10. //Other
  11. fsql.Select<YourType>()
  12. .Where(a => a.IsDelete == 0)
  13. .WhereIf(keyword != null, a => a.UserName.Contains(keyword))
  14. .WhereIf(role_id > 0, a => a.RoleId == role_id)
  15. .Where(a => a.Nodes.Any(t => t.Parent.Id == t.UserId))
  16. .Count(out var total)
  17. .Page(page, size)
  18. .OrderByDescending(a => a.Id)
  19. .ToList()

More..

  1. fsql.Select<Song>().Where(a => new[] { 1, 2, 3 }.Contains(a.Id)).ToList();
  2. fsql.Select<Song>().Where(a => a.CreateTime.Date == DateTime.Today).ToList();
  3. fsql.Select<Song>().OrderBy(a => Guid.NewGuid()).Limit(10).ToList();
  4. fsql.Select<Song>().ToList(a => new
  5. {
  6. a.Id,
  7. Tags = fsql.Select<Tag>().ToList(),
  8. SongTags = fsql.Select<SongTag>().Where(b => b.TopicId == a.Id).ToList()
  9. });

🚁 Repository

dotnet add package FreeSql.Repository

  1. [Transactional]
  2. public void Add() {
  3. var repo = ioc.GetService<BaseRepository<Tag>>();
  4. repo.DbContextOptions.EnableCascadeSave = true;
  5. var item = new Tag {
  6. Name = "testaddsublist",
  7. Tags = new[] {
  8. new Tag { Name = "sub1" },
  9. new Tag { Name = "sub2" }
  10. }
  11. };
  12. repo.Insert(item);
  13. }

Reference: Use TransactionalAttribute and UnitOfWorkManager in ASP.NET Core to Achieve the Multiple Transaction Propagation.
