JCode.ORMX.DbProvider.PostgreSQL

PostgreSQL 数据库提供程序，用于 JCode.ORMX 框架。

快速开始

安装

Install-Package JCode.ORMX.DbProvider.PostgreSQL

基本用法

using JCode.ORMX.DbProvider.PostgreSQL;
using JCode.ORMX.Attributes;

// 定义实体
[Table("Users")]
public class User
{
    [Column(IsPrimaryKey = true, IsIdentity = true)]
    public int Id { get; set; }
    
    [Column]
    public string Name { get; set; }
    
    [Column]
    public string Email { get; set; }
}

// 初始化
using var provider = new PostgreSQLProvider("Host=localhost;Database=MyDb;Username=postgres;Password=your_password;");
var tableManager = provider.GetTableManager();

// 创建表
tableManager.Create(typeof(User));

// CRUD 操作
var table = tableManager.Table<User>();

// 插入
var user = table.Insert(new User { Name = "John", Email = "john@example.com" });

// 查询
var users = table.Where(u => u.Name == "John").GetList();

// 更新
table.Update(u => u.Email, "newemail@example.com");

// 删除指定实体
table.Delete(user);

// 或使用条件删除
table.Where(u => u.Id == 1).Delete();

功能特性

✅ 完整的 PostgreSQL 支持
✅ 类型安全的 LINQ 查询
✅ 事务支持
✅ 批量操作（InsertAll/UpdateAll/DeleteAll）
✅ JSON/JSONB 类型支持
✅ 数组类型支持
✅ 全文搜索支持
✅ 参数化查询（防 SQL 注入）
✅ 智能 SQL 调试

链式查询

ORMX 提供流畅的链式查询 API：

// 复杂查询
var result = table
    .Where(u => u.Age > 18)
    .OrderByDesc(u => u.CreatedAt)
    .Limit(10)
    .GetList();

// 聚合查询
var count = table.Count();
var maxAge = table.Max(u => u.Age);

SQL 调试

// 查看生成的 SQL
table.Extension((extObj) =>
{
    Console.WriteLine($"SQL: {extObj.Query}");
    Console.WriteLine($"参数：{string.Join(", ", extObj.Parameters)}");
})
.Where(u => u.Age > 25)
.GetList();

特殊功能

JSON 类型支持

[Table("Products")]
public class Product
{
    [Column]
    public Dictionary<string, object> Attributes { get; set; }  // JSONB 类型
}

var products = table.Where(p => p.Attributes["color"] == "red").GetList();

数组类型支持

[Table("Articles")]
public class Article
{
    [Column]
    public string[] Tags { get; set; }  // 数组类型
}

var articles = table.Where(a => a.Tags.Contains("technology")).GetList();
