事务

描述

Dapper支持事务和范围事务。

事务

从连接开始一个新事务，并将其传递给事务可选参数。

var sql = "Invoice_Insert";

using (var connection = My.ConnectionFactory())
{
    connection.Open();

    using (var transaction = connection.BeginTransaction())
    {
        var affectedRows = connection.Execute(sql,
            new {Kind = InvoiceKind.WebInvoice, Code = "Single_Insert_1"},
            commandType: CommandType.StoredProcedure,
            transaction: transaction);

        transaction.Commit();
    }
}

范围事务

在开始连接之前开始一个新的范围事务。

// using System.Transactions;

using (var transaction = new TransactionScope())
{
    var sql = "Invoice_Insert";

    using (var connection = My.ConnectionFactory())
    {
        connection.Open();

        var affectedRows = connection.Execute(sql,
            new {Kind = InvoiceKind.WebInvoice, Code = "Single_Insert_1"},
            commandType: CommandType.StoredProcedure);
    }

    transaction.Complete();
}
