SSIS: Excecute SSIS package (DTSX) from ASP.Net

Written by – santosh poojari – This article demonstrate the step by step procedure to create SSIS Package and Execute the same using ASP.net

Introduction

I got a task to develop the web page that execute SQL server 2005 SSIS package. With less knowledge of SSIS it was difficult for me to get the solution right at first time. But with online help I was able to crack the problem. I created a simple DTSX package which takes spreadsheet data and pumps it into a database table and then I execute store procedure inside the package to perform manipulation in database table. These whole bunch of process are then executed through asp.net. Below I have demonstrate the steps to achieve this.

Creation of SSIS Package

Prerequisite:

1)Database table:

CREATE TABLE [dbo].[tblBusiness](
	[Business_ID] [numeric](18, 0) NULL,
	[Business_Name] [nvarchar](50) NULL
) ON [PRIMARY]

2)Excel data:BusinessTemplate.xls

SSIS Package Workflow design:

  • Invoke SQL task

to delete the tblBusiness data.

  • Load Excel data into database table tblBusiness.
  • Invoke SQL task to update database table tblBusiness.

Step 1: Load Excel data into database table tblBusiness.

1. Click on ‘SSIS Import Export Wizard’ Under ‘Project’ Menu.

2.Click on Next Button.

3.Choose Source and click next.

In our case source is Excel .The path specified will be overwritten when assigned through .net code.

E.g. package.Connections[“SourceConnectionExcel”].ConnectionString = “provider=Microsoft.Jet.OLEDB.4.0;data source=” + tbFileName.Text + “;Extended Properties=Excel 8.0; “;

3.Choose Destination and click next.

4.Choose Copy data from one or more table and Click next

5.Complete Wizard Screen appears and Click finish.

Once the above steps are completed one can see the following views

Under control Flow Tab:

Under Data Flow Tab:

Note: In Connection Manager two connection objects appears:

  • Excel Connection Object:SourceConnectionExcel
  • SQL Server: DestinationConnectionOLEDB

Double Click on each object to verify the connection string and save it again.Just test whether Dataflow is correctly built.If turns green then dataflow is successfully executed . If turns RED then there is problem with connection string.

Step 2: Create Sql Task Script to delete the database table.

1. Create Global Package level variable.These variables are input parameters to package. So the package having sql storeprocedure can consume these input param.

2)Double Click on ‘Preparation SQL Task’ under Control Flow Tab.

We have taken “EXEC DeleteBusinessEntry ?” this procedure is going to take input parameter @Business_ID .

Create Storeprocedure:

CREATE PROCEDURE DeleteBusinessEntry 
	@Business_ID bigint	
AS
BEGIN
	Delete from tblBusiness where Business_ID=@Business_ID
END

3)Click on ParameterMapping so as to map Global user defined input varible to storeproc input variable. It is case sensitive.Also take care of the datatype and size of the datatype.Each variable should have different ParameterName in it.

Step 2: Create Sql Task Script to update database table content that is loaded with excel data.

Drag and Drop ‘Execute Sql Task’ from toolbox on to control flow screen. Connect Prepare Sql task to dataflow task.Also connect Dataflow task to SQl Script task object.

2)Double Click on ‘Execute Sql Task’ under Control Flow Tab.

We have taken “EXEC UpdateBusinessEntry ?,?” this procedure is going to take two input parameters @Business_ID /@Business_Name.

Create Storeprocedure:

CREATE PROCEDURE UpdateBusinessEntry 
	@Business_ID bigint	,
	@Business_Name varchar(100)	
AS
BEGIN
	Update  tblBusiness 
	Set Business_Name=@Business_Name
	where Business_ID=@Business_ID
END

3)Click on ParameterMapping so as to map Global user defined input varible to storeproc input variable. It is case sensitive.Also take care of the datatype and size of the datatype. Each variable should have different ParameterName in it.

On completion of above three steps run the package .

Execute SSIS Package Using ASP.Net

The Important reference : Microsoft.SqlServer.ManagedDTS

The below code snippet is self explanatory

       using Microsoft.SqlServer.Dts.Runtime;
        
       protected void btnExecute_Click(object sender, EventArgs e)
       {
            Application app = new Application();
            Package package = null;
            try
            {
            string fileName = 
Server.MapPath(System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName.ToString()));
            FileUpload1.PostedFile.SaveAs(fileName);
            
            //Load DTSX
            package = 
app.LoadPackage(@"D:\SSIS_ASP_NET\SSIS_ASP_NET_DEMO\SSIS_ASP_NET_DEMO\Package1.dtsx", null);
            
            //Global Package Variable
            Variables vars = package.Variables;
            vars["Business_ID"].Value = txtBusinessID.Text;
            vars["Business_Name"].Value = txtBusinessName.Text;
            
            //Specify Excel Connection From DTSX Connection Manager
            package.Connections["SourceConnectionExcel"].ConnectionString =
 "provider=Microsoft.Jet.OLEDB.4.0;data source=" + fileName + ";Extended Properties=Excel 8.0; ";
            
            //Execute DTSX.
            Microsoft.SqlServer.Dts.Runtime.DTSExecResult results = package.Execute();
        }
        catch (Exception ex)
        {
            throw ex;
        }
        finally
        {
            package.Dispose();
            package = null;
        }
    }

The important factor in above code is to assign the data source of excel file to the SSIS package as package.Connections[“SourceConnectionExcel”].ConnectionString
