Unity uses SQLite

I think the Internet is full of quotes sqlite3.dll,Mono.Data.Sqlite.dll,System.Data.dll, such as Setup Database (SQLite) for Unity
Or some third-party import methods unity-3rdparty-sqlite-net
Or import through a third-party package management tool Unity3D introduction ： How to manage Unity In the project NuGet package ？ Use of third parties NuGet Package manager ——NuGetForUnity
But I found that Unity About Sqlite The library of Unity.VisualScripting.Dependencies.Sqlite.SQLiteConnection , Information has Unity.VisualScripting.Dependencies.Sqlite.SQLiteConnection
So I made a simple addition, deletion, modification and check demo,Unity.VisualScripting.Dependencies.Sqlite.SQLiteConnection Sure Use it directly , It can be done. Yes Sqlite The operation of
Here's the key code
Create table

using (var db = new SQLiteConnection(databasePath, SQLiteOpenFlags.ReadWrite)){    var count = db.CreateTable<UserInfo>();    count = db.CreateTable<RandomEvent>();}

Add data

using (var db = new SQLiteConnection(databasePath, SQLiteOpenFlags.ReadWrite)){    var count = db.Insert(new UserInfo()    {        Name = "test1Name",        Sex = SexEnum.Woman,        Birthday = new DateTime(1990, 10, 2)    }, typeof(UserInfo));    List<UserInfo> users = new List<UserInfo>();    users.Add(new UserInfo()    {        Name = "test2Name",        Sex = SexEnum.Man,        Birthday = new DateTime(2000, 10, 2)    });    users.Add(new UserInfo()    {        Name = "test3Name",        Sex = SexEnum.Woman,        Birthday = new DateTime(2004, 10, 2)    });    count = db.InsertAll(users, typeof(UserInfo));}

Modifying data

using (var db = new SQLiteConnection(databasePath, SQLiteOpenFlags.ReadWrite)){    var count = db.Update(new UserInfo()    {        Id = 3,        Name = "test1Name-Update",        Sex = SexEnum.Woman,        Birthday = new DateTime(1990, 10, 2)    }, typeof(UserInfo));}

Delete data

using (var db = new SQLiteConnection(databasePath, SQLiteOpenFlags.ReadWrite)){    string sql = "select Id,Name,Sex,Birthday from UserInfo where Id =3";    var data = new object[] { "Id", "Name", "Sex", "Birthday" };    var deleteData = db.Query(new TableMapping(typeof(UserInfo)), sql, data).FirstOrDefault();    if (deleteData != null)    {        var count = db.Delete(deleteData);    }    var count2 = db.Delete<UserInfo>(4);}

Query data

using (var db = new SQLiteConnection(databasePath, SQLiteOpenFlags.ReadWrite)){    string sql = "select Id,Question,[Order] from RandomEvent";    var data = new object[] { "Id", "Question", "[Order]" };    var datas = db.Query(new TableMapping(typeof(RandomEvent)), sql, data);    //enum not work :(    //var datas2 = db.Find<UserInfo>(user => user.Name.Contains("test"));    var datas2 = db.Find<RandomEvent>(randomEvent => randomEvent.Question.Contains("q"));    var data3 = db.Get<UserInfo>(1);}

Data sheets need to be declared

[Table(name: nameof(RandomEvent))]public class RandomEvent{    [PrimaryKey, AutoIncrement]    public int Id { get; set; }    public string Question { get; set; }    public int Order { get; set; }}

[Table(name: nameof(UserInfo))]public class UserInfo{    [PrimaryKey, AutoIncrement]    public int Id { get; set; }    public string Name { get; set; }    public SexEnum Sex { get; set; }    public DateTime Birthday { get; set; }}
