描述

Dapper通过支持匿名类型使其可以简单、安全（SQL注入）的使用参数。

单次

执行一次SQL命令。

var sql = "EXEC 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);

    My.Result.Show(affectedRows);
}

多次

执行多次SQL命令。

var sql = "EXEC Invoice_Insert";

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

    var affectedRows = connection.Execute(sql,
        new[]
        {
            new {Kind = InvoiceKind.WebInvoice, Code = "Many_Insert_1"},
            new {Kind = InvoiceKind.WebInvoice, Code = "Many_Insert_2"},
            new {Kind = InvoiceKind.StoreInvoice, Code = "Many_Insert_3"}
        },
        commandType: CommandType.StoredProcedure
    );
