Realizar inserciones y actualizaciones con Dapper

Estoy interesado en usar Dapper, pero por lo que puedo decir, solo admite Query and Execute. No veo que Dapper incluya una forma de Insertar y Actualizar objetos.

Dado que nuestro proyecto (¿la mayoría de los proyectos?) Necesita hacer inserciones y actualizaciones, ¿cuál es la mejor práctica para hacer Inserciones y Actualizaciones junto con dapper?

Preferiblemente no tendríamos que recurrir al método ADO.NET de construcción de parámetros, etc.

La mejor respuesta que puedo encontrar en este momento es usar LinqToSQL para inserciones y actualizaciones. ¿Hay una mejor respuesta?

Estamos buscando construir algunos ayudantes, todavía decidimos sobre las API y si esto va en el núcleo o no. Consulte: https://code.google.com/archive/p/dapper-dot-net/issues/6 para ver el progreso.

Mientras tanto, puedes hacer lo siguiente

val = "my value";
cnn.Execute("insert into Table(val) values (@val)", new {val});

cnn.Execute("update Table set val = @val where Id = @id", new {val, id = 1});

etcétera

Actualizar

Como se señaló en los comentarios, ahora hay varias extensiones disponibles en el proyecto Dapper.Contrib en forma de estos IDbConnectionmétodos de extensión:

T Get<T>(id);
IEnumerable<T> GetAll<T>();
int Insert<T>(T obj);
int Insert<T>(Enumerable<T> list);
bool Update<T>(T obj);
bool Update<T>(Enumerable<T> list);
bool Delete<T>(T obj);
bool Delete<T>(Enumerable<T> list);
bool DeleteAll<T>();

Realizar operaciones CRUD con Dapper es una tarea fácil. He mencionado los siguientes ejemplos que deberían ayudarlo en las operaciones CRUD.

Código para C RUD:

Método n. ° 1: este método se utiliza cuando inserta valores de diferentes entidades.

using (IDbConnection db = new SqlConnection(ConfigurationManager.ConnectionStrings["myDbConnection"].ConnectionString))
{
    string insertQuery = @"INSERT INTO [dbo].[Customer]([FirstName], [LastName], [State], [City], [IsActive], [CreatedOn]) VALUES (@FirstName, @LastName, @State, @City, @IsActive, @CreatedOn)";

    var result = db.Execute(insertQuery, new
    {
        customerModel.FirstName,
        customerModel.LastName,
        StateModel.State,
        CityModel.City,
        isActive,
        CreatedOn = DateTime.Now
    });
}

Método # 2: Este método se usa cuando las propiedades de su entidad tienen los mismos nombres que las columnas SQL. Entonces, Dapper es un ORM que asigna propiedades de entidad con las columnas SQL coincidentes.

using (IDbConnection db = new SqlConnection(ConfigurationManager.ConnectionStrings["myDbConnection"].ConnectionString))
{
    string insertQuery = @"INSERT INTO [dbo].[Customer]([FirstName], [LastName], [State], [City], [IsActive], [CreatedOn]) VALUES (@FirstName, @LastName, @State, @City, @IsActive, @CreatedOn)";

    var result = db.Execute(insertQuery, customerViewModel);
}

Código para C R UD:

using (IDbConnection db = new SqlConnection(ConfigurationManager.ConnectionStrings["myDbConnection"].ConnectionString))
{
    string selectQuery = @"SELECT * FROM [dbo].[Customer] WHERE FirstName = @FirstName";

    var result = db.Query(selectQuery, new
    {
        customerModel.FirstName
    });
}

Código para CR U D:

using (IDbConnection db = new SqlConnection(ConfigurationManager.ConnectionStrings["myDbConnection"].ConnectionString))
{
    string updateQuery = @"UPDATE [dbo].[Customer] SET IsActive = @IsActive WHERE FirstName = @FirstName AND LastName = @LastName";

    var result = db.Execute(updateQuery, new
    {
        isActive,
        customerModel.FirstName,
        customerModel.LastName
    });
}

Código para CRU D :

using (IDbConnection db = new SqlConnection(ConfigurationManager.ConnectionStrings["myDbConnection"].ConnectionString))
{
    string deleteQuery = @"DELETE FROM [dbo].[Customer] WHERE FirstName = @FirstName AND LastName = @LastName";

    var result = db.Execute(deleteQuery, new
    {
        customerModel.FirstName,
        customerModel.LastName
    });
}

puedes hacerlo de esta manera:

sqlConnection.Open();

string sqlQuery = "INSERT INTO [dbo].[Customer]([FirstName],[LastName],[Address],[City]) VALUES (@FirstName,@LastName,@Address,@City)";
sqlConnection.Execute(sqlQuery,
    new
    {
        customerEntity.FirstName,
        customerEntity.LastName,
        customerEntity.Address,
        customerEntity.City
    });

sqlConnection.Close();

Usando Dapper.Contrib es tan simple como esto:

Insertar lista:

public int Insert(IEnumerable<YourClass> yourClass)
{
    using (SqlConnection conn = new SqlConnection(ConnectionString))
    {
        conn.Open();
        return conn.Insert(yourClass) ;
    }
}

Insertar single:

public int Insert(YourClass yourClass)
{
    using (SqlConnection conn = new SqlConnection(ConnectionString))
    {
        conn.Open();
        return conn.Insert(yourClass) ;
    }
}

Lista de actualizacion:

public bool Update(IEnumerable<YourClass> yourClass)
{
    using (SqlConnection conn = new SqlConnection(ConnectionString))
    {
        conn.Open();
        return conn.Update(yourClass) ;
    }
}

Actualizar solo:

public bool Update(YourClass yourClass)
{
    using (SqlConnection conn = new SqlConnection(ConnectionString))
    {
        conn.Open();
        return conn.Update(yourClass) ;
    }
}

También puede usar apuesto con un procedimiento almacenado y una forma genérica por la cual todo es fácilmente manejable.

Define tu conexión:

public class Connection: IDisposable
{
    private static SqlConnectionStringBuilder ConnectionString(string dbName)
    {
        return new SqlConnectionStringBuilder
            {
                ApplicationName = "Apllication Name",
                DataSource = @"Your source",
                IntegratedSecurity = false,
                InitialCatalog = Database Name,
                Password = "Your Password",
                PersistSecurityInfo = false,
                UserID = "User Id",
                Pooling = true
            };
    }

    protected static IDbConnection LiveConnection(string dbName)
    {
        var connection = OpenConnection(ConnectionString(dbName));
        connection.Open();
        return connection;
    }

    private static IDbConnection OpenConnection(DbConnectionStringBuilder connectionString)
    {
        return new SqlConnection(connectionString.ConnectionString);
    }

    protected static bool CloseConnection(IDbConnection connection)
    {
        if (connection.State != ConnectionState.Closed)
        {
            connection.Close();
            // connection.Dispose();
        }
        return true;
    }

    private static void ClearPool()
    {
        SqlConnection.ClearAllPools();
    }

    public void Dispose()
    {
        ClearPool();
    }
}

Cree una interfaz para definir los métodos Dapper que realmente necesita:

 public interface IDatabaseHub
    {
   long Execute<TModel>(string storedProcedureName, TModel model, string dbName);

        /// <summary>
        /// This method is used to execute the stored procedures with parameter.This is the generic version of the method.
        /// </summary>
        /// <param name="storedProcedureName">This is the type of POCO class that will be returned. For more info, refer to https://msdn.microsoft.com/en-us/library/vstudio/dd456872(v=vs.100).aspx. </param>
        /// <typeparam name="TModel"></typeparam>
        /// <param name="model">The model object containing all the values that passes as Stored Procedure's parameter.</param>
        /// <returns>Returns how many rows have been affected.</returns>
        Task<long> ExecuteAsync<TModel>(string storedProcedureName, TModel model, string dbName);

        /// <summary>

        /// <returns>Returns how many rows have been affected.</returns>         
        long Execute(string storedProcedureName, DynamicParameters parameters, string dbName);

                    }
                    catch (Exception exception)
                    {
                        throw exception;
                    }
                    finally
                    {
                        CloseConnection(connection);
                    }
                }
            }

    }

Ahora puede llamar desde el modelo según lo necesite:

public class DeviceDriverModel : Base
    {
 public class DeviceDriverSaveUpdate
        {
            public string DeviceVehicleId { get; set; }
            public string DeviceId { get; set; }
            public string DriverId { get; set; }
            public string PhoneNo { get; set; }
            public bool IsActive { get; set; }
            public string UserId { get; set; }
            public string HostIP { get; set; }
        }


        public Task<long> DeviceDriver_SaveUpdate(DeviceDriverSaveUpdate obj)
        {

            return DatabaseHub.ExecuteAsync(
                    storedProcedureName: "[dbo].[sp_SaveUpdate_DeviceDriver]", model: obj, dbName: AMSDB);//Database name defined in Base Class.
        }
}

También puede pasar parámetros también:

public Task<long> DeleteFuelPriceEntryByID(string FuelPriceId, string UserId)
        {


            var parameters = new DynamicParameters();
            parameters.Add(name: "@FuelPriceId", value: FuelPriceId, dbType: DbType.Int32, direction: ParameterDirection.Input);
            parameters.Add(name: "@UserId", value: UserId, dbType: DbType.String, direction: ParameterDirection.Input);

            return DatabaseHub.ExecuteAsync(
                    storedProcedureName: @"[dbo].[sp_Delete_FuelPriceEntryByID]", parameters: parameters, dbName: AMSDB);

        }

Ahora llame desde sus controladores:

var queryData = new DeviceDriverModel().DeviceInfo_Save(obj);

Espero que evite la repetición de su código y brinde seguridad;

Puedes probar esto:

 string sql = "UPDATE Customer SET City = @City WHERE CustomerId = @CustomerId";             
 conn.Execute(sql, customerEntity);
