我的asp.net表单中有教育资格块,一组qulification将作为行插入表中。所以我想插入这些集合,假设在一次拍摄中有3组限定条件,例如表格中的3个插入行。我不想创建多个插入队列,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。
我们将不胜感激。

您可以从客户端生成XML并将其发送到SP -
<强> SP:强>
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
<强> Exec的:强>
DECLARE @XML XML
SELECT @XML = '
<root>
<sd ScheduleID="11324" DateOut="2009-01-01T00:00:00" AbsenceCode="offdays" />
<sd ScheduleID="11324" DateOut="2009-01-02T00:00:00" WorkShiftCD="1/10" />
<sd ScheduleID="11324" DateOut="2009-01-03T00:00:00" WorkShiftCD="1/11,5" />
<sd ScheduleID="11324" DateOut="2009-01-04T00:00:00" WorkShiftCD="1/7" />
<sd ScheduleID="11324" DateOut="2009-01-05T00:00:00" AbsenceCode="business_trip" />
<sd ScheduleID="11324" DateOut="2009-01-06T00:00:00" AbsenceCode="offdays" />
</root>'
EXEC dbo.sp_test @XML = @XML

如果您使用的是SQL Server 2008,请使用Table-Valued Parameters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
)
创建一个过程以将值从TVP插入到目标表
CREATE PROCEDURE usp_tvp_Insert @ItemTVP tvp_Insert READONLY
AS
BEGIN
INSERT INTO YourTable (ID, Name)
SELECT ID, Name
FROM @ItemTVP
END
C#代码
SqlCommand sqlCmd = new SqlCommand("usp_tvp_Insert", con);
sqlCmd.CommandType = CommandType.StoredProcedure;
SqlParameter tvpParam = sqlCmd.Parameters.AddWithValue("@ItemTVP", datatable);
//Pass the datatable above
tvpParam.SqlDbType = SqlDbType.Structured; //passing TVP
sqlCmd.ExecuteNonQuery();

您可以在代码中使用SqlBulkCopy,如下面的代码
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;
}
}
