Bulk Inserts with Stored Procedures

Hello

I want a .net App to send data in bulk to a stored procedure, which will then use this data to delete all data in an existing table and perform a bulk insert.

Question: What type of variable do I use in my stored procedure?  Examples of code in .net that call a stored procedure with a 'bulk input' type of parameter? Example of a stored procedur that gets a 'bulk input' type of parameter and performs a bulk input

thanks

I would prefer to use XML data type for bulk operations.
Please refer below example;

.NET code:


        public void BulkOperation()
        {
            string cns = @"Data Source=VIPSLAPTOP\SQLEXPRESS;Initial Catalog=ExpertsExchange;Integrated Security=SSPI;";
            string records = "<Operations>" +
                                    "<Delete>" +
                                        "<Row>" +
                                            "<ID>1</ID>" +
                                        "</Row>" +
                                        "<Row>" +
                                            "<ID>2</ID>" +
                                        "</Row>" +
                                    "</Delete>" +
                                    "<Insert>" +
                                        "<Row>" +
                                            "<ID>5</ID>" +
                                            "<Data>Five</Data>" +
                                        "</Row>" +
                                        "<Row>" +
                                            "<ID>6</ID>" +
                                            "<Data>Six</Data>" +
                                        "</Row>" +
                                    "</Insert>" +
                                    "<Update>" +
                                        "<Row>" +
                                            "<ID>3</ID>" +
                                            "<Data>vrluckyin</Data>" +
                                        "</Row>" +
                                    "</Update>" +
                                "</Operations>";
            SqlConnection cn = new SqlConnection(cns);
            cn.Open();
            SqlCommand cmd = new SqlCommand();
            cmd.Connection = cn;
            cmd.CommandText = "BulkOperations";
            cmd.CommandType = System.Data.CommandType.StoredProcedure;
            SqlParameter parameter = new SqlParameter("@Records", System.Data.SqlDbType.Xml);
            parameter.Value = records;
            cmd.Parameters.Add(parameter);
            cmd.ExecuteNonQuery();
            cn.Close();
        }

NOTE: You can also use LINQ, EntityFramework, MDAC for data access code.
Stored Procedure:

Sorry ;) , I forgot to attach code for SQL table Q_26475408
CREATE TABLE [dbo].[Q_26475408](
	[ID] [int] NULL,
	[Data] [varchar](50) NULL
)

Every thing works fine within a stored procedure.

But I get an arithmentic overflow when inserting the following value into a datetime column.

<DTime>15/09/2000 10:00:00</DTime>

I get a similiar conversion error if I try the following:

<DTime>#15/09/2000 10:00:00#</DTime>

How do i store a date and time stamp.

see sample SP below:
ALTER PROCEDURE [dbo].[usp_InsertBatchLogFromPLC]

                  ,col.value('PT01A[1]','numeric(3,2)') AS PT01A

                  ,col.value('PhaseTime[1]','numeric(3,2)') AS PhaseTime

      )
      
      INSERT INTO Batch1Log

Vipul Patel.NET ExpertCommented:
The reason is that you are using DD/MM/YYYY date format.

NOTE: 103 indicates DD/MM/YYYY date format.

Your query should be look like;


 
;WITH InsertRecords AS
      (
            SELECT 
                  col.value('UserName[1]','VARCHAR(50)') AS UserName
                  ,col.value('Phase[1]','VARCHAR(20)') AS Phase
                  ,CONVERT(DATETIME,col.value('DTime[1]','VARCHAR(50)'),103) AS DTime
                  ,col.value('PT01A[1]','numeric(3,2)') AS PT01A
                  ,col.value('RTD01A[1]','numeric(3,2)') AS RTD01A
                  ,col.value('LOAD1[1]','numeric(3,2)') AS LOAD1
                  ,col.value('LOAD2[1]','numeric(3,2)') AS LOAD2
                  ,col.value('LOAD3[1]','numeric(3,2)') AS LOAD3
                  ,col.value('LOAD4[1]','numeric(3,2)') AS LOAD4
                  ,col.value('LOAD5[1]','numeric(3,2)') AS LOAD5
                  ,col.value('LOAD6[1]','numeric(3,2)') AS LOAD6
                  ,col.value('FoMin[1]','numeric(3,2)') AS FoMin
                  ,col.value('FoMax[1]','numeric(3,2)') AS FoMax
                  ,col.value('PhaseTime[1]','numeric(3,2)') AS PhaseTime
