使用asp.net在单个命令中插入多行

我在asp.net表单中有教育资格块，一组资格将作为行插入表中。所以我想插入这些集合，假设一个镜头中有3组限定条件，就像在表中的一个镜头中插入3行一样。我不想创建多个插入请求，因为我正在使用存储过程。我听说xml可以完成这项工作，但不确定

非常感谢您的帮助。

您可以从客户端生成XML并将其发送到SP-

SP:

CREATE PROCEDURE dbo.sp_test

    @XML XML

AS BEGIN

    SET NOCOUNT ON

    --INSERT INTO dbo.ScheduleDetail (ScheduleID, DateOut, WorkShiftCD, AbsenceCode)
    SELECT 
          ScheduleID = t.p.value('@ScheduleID', 'INT') 
        , DateOut = t.p.value('@DateOut', 'DATETIME') 
        , WorkShiftCD = t.p.value('@WorkShiftCD', 'VARCHAR(50)') 
        , AbsenceCode = t.p.value('@AbsenceCode', 'VARCHAR(50)') 
    FROM @XML.nodes('root/sd') t(p)

    RETURN 0

END

DECLARE @XML XML

如果您使用的是SQL Server 2008，则使用一次性执行插入操作

创建

TVP

CREATE TYPE tvp_Insert AS TABLE
    (
     [ID] [int] NOT NULL,
     [Name] [nvarchar](50) NULL
    )

创建将值从TVP插入目标表的过程

CREATE PROCEDURE usp_tvp_Insert  @ItemTVP tvp_Insert READONLY
AS
BEGIN
INSERT INTO YourTable (ID, Name)
SELECT ID, Name
FROM @ItemTVP
END

您可以在代码中使用SqlBulkCopy，如下代码所示

public void InsertDataTable(DataTable dt)
{
    try
    {

        if (dt.Rows.Count > 0)
        {
            SqlBulkCopy bulk = new SqlBulkCopy(ConnectionString);
            bulk.DestinationTableName = "YourTableName";
            bulk.WriteToServer(dt);
        }

    }
    catch (Exception)
    {
        throw;
    }
}

如何将行的值发送到存储过程…？是的，我将把列的值发送到存储过程。在其中，以表的形式或以个人参数的形式？如何将行的值发送到存储过程…？是的，我将把列的值发送到存储过程。在其中，以表的形式或以个人参数的形式？多个插入查询如何在此基础上工作。以及SP中insert语句的位置。请给出建议。您可以在asp.net表单中生成XML（由StringBuilder等生成），然后使用XML参数执行SP。请参阅行：insert INTO dbo.ScheduleDetail（ScheduleID、DateOut、Workshift CD、缺席代码）尝试以下操作：多个insert查询如何处理此操作。SP中insert语句的位置。请给出建议。您可以在asp.net表单中生成XML（由StringBuilder等生成），然后使用XML参数执行SP。请参阅行：insert INTO dbo.ScheduleDetail（ScheduleID、DateOut、Workshift CD、缺席代码）尝试以下操作：
