Melakukan Sisipan dan Pembaruan dengan Dapper

Saya tertarik menggunakan Dapper - tetapi dari apa yang saya tahu itu hanya mendukung Query dan Execute. Saya tidak melihat bahwa Dapper termasuk cara Memasukkan dan Memperbarui objek.

Mengingat bahwa proyek kami (sebagian besar proyek?) Perlu melakukan sisipan dan pembaruan, apa praktik terbaik untuk melakukan Sisipan dan Pembaruan bersama necis?

Lebih disukai kita tidak perlu menggunakan metode ADO.NET untuk membangun parameter, dll.

Jawaban terbaik yang dapat saya temukan pada saat ini adalah menggunakan LinqToSQL untuk memasukkan dan memperbarui. Apakah ada jawaban yang lebih baik?

Kami sedang membangun beberapa pembantu, masih memutuskan API dan apakah ini berjalan pada intinya atau tidak. Lihat: https://code.google.com/archive/p/dapper-dot-net/issues/6 untuk kemajuan.

Sementara itu, Anda dapat melakukan hal berikut

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});

dan sebagainya

Memperbarui

Seperti yang ditunjukkan dalam komentar, sekarang ada beberapa ekstensi yang tersedia di proyek Dapper.Contrib dalam bentuk IDbConnectionmetode ekstensi ini :

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>();

Melakukan operasi CRUD menggunakan Dapper adalah tugas yang mudah. Saya telah menyebutkan contoh di bawah ini yang dapat membantu Anda dalam operasi CRUD.

Kode untuk C RUD:

Metode # 1: Metode ini digunakan ketika Anda memasukkan nilai dari entitas yang berbeda.

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
    });
}

Metode # 2: Metode ini digunakan ketika properti entitas Anda memiliki nama yang sama dengan kolom SQL. Jadi, Dapper menjadi properti entitas peta ORM dengan kolom SQL yang cocok.

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);
}

Kode untuk 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
    });
}

Kode untuk 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
    });
}

Kode untuk 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
    });
}

Anda bisa melakukannya dengan cara seperti ini:

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();

Menggunakan Dapper.Contrib semudah ini:

Sisipkan daftar:

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

Sisipkan tunggal:

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

Perbarui daftar:

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

Perbarui tunggal:

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

Anda juga dapat menggunakan necis dengan prosedur tersimpan dan cara umum yang dengannya semuanya mudah dikelola.

Tentukan koneksi Anda:

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();
    }
}

Buat antarmuka untuk menentukan metode Dapper yang sebenarnya Anda butuhkan:

 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>
        /// This method is used to execute the stored procedures with parameter. This is the generic version of the method.
        /// </summary>

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

        /// <summary>

        Task<long> ExecuteAsync(string storedProcedureName, DynamicParameters parameters, string dbName);
}

Implementasikan antarmuka:

                    }
                }
            }

    }

Anda sekarang dapat menelepon dari model sesuai kebutuhan Anda:

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.
        }
}

Anda juga dapat mengirimkan parameter:

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);

        }

Sekarang telepon dari pengontrol Anda:

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

Semoga itu mencegah pengulangan kode Anda dan memberikan keamanan;

Anda dapat mencoba ini:

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