HotConexionDB

It is a library written in C # that allows manipulating interactions with databases more easily.

How use it

Basic use

CREATE TABLE Heroes(
	HeroId int,
	HeroName varchar(64),
	AlterEgo varchar(125),
	UniverseId int
)

public class Hero
{
	public int HeroId { get; set; }
	public string HeroName { get; set; }
	public string AlterEgo { get; set; }
	public int UniverseId { get; set; }
}

Conexion conexion = new Conexion(ConexionType.MSSQLServer, "server", "database", "username", "password");

var result = conexion.ExecuteWithResults<Hero>("SELECT TOP 5 * FROM Heroes");

foreach (var hero in result.Data)
{
	Console.WriteLine(hero.HeroName);
}

This returns an object of type Result where the resultset is stored in the Data property of the object.

Parameters

ConexionParameters parameters = new ConexionParameters();
parameters.Add("@HeroId", ConexionDbType.Int, 1);

var result = conexion.ExecuteWithResults<Hero>("GetHeroById", parameters);

foreach (var hero in result.Data)
{
	Console.WriteLine(hero.HeroName);
}

DataSet & DataTable

ConexionParameters parameters = new ConexionParameters();
parameters.Add("@HeroId", ConexionDbType.Int, 1); 

var result = conexion.ExecuteWithResults<Hero>("GetHeroById", parameters, out DataSet ds);

var result2 = conexion.ExecuteWithResults<Hero>("GetHeroById", parameters, out DataTable dt);

Read by row

ConexionParameters parameters = new ConexionParameters();
parameters.Add("@Name", ConexionDbType.VarChar, "bat");

conexion.ExecuteWithResults("GetHeroesByName",
			    parameters,
			    row =>
			    {
			        Console.WriteLine("{0} \t {1}", 
				row["HeroId"].ToInt32(), 
				row["HeroName"].ToString());                      
			    });

Mapping column name

CREATE TABLE Heroes(
	HeroId int,
	HeroName varchar(64),
	AlterEgo varchar(125),
	UniverseId int
)

If you want mapping a column name in the object class you can use the attributte ConexionColumn.

public class Hero
{
	[ConexionColumn("HeroId")]
	public int Id { get; set; }
	
	[ConexionColumn("HeroName")]
	public string Name { get; set; }
	
	public string AlterEgo { get; set; }
	
	public int UniverseId { get; set; }
}

ConexionParameters parameters = new ConexionParameters();
parameters.Add("@HeroId", ConexionDbType.Int, 1);

var result = conexion.ExecuteWithResults<Hero>("GetHeroById", parameters);

foreach (var hero in result.Data)
{
	Console.WriteLine(hero.Name);
}

Multiples recordsets

conexion.RecordsetsExecute(@"SELECT TOP 10 * FROM Heroes; 
SELECT TOP 5 * FROM Villains");

var heroes = conexion.RecordsetsResults<Hero>();
var villains = conexion.RecordsetsResults<Villain>();

foreach (var hero in heroes.Data)
{
	Console.WriteLine(hero.Name);
}

foreach (var villain in villains.Data)
{
	Console.WriteLine(villain.Name);
}

Try it, enjoy it and have fun 😄
