Abstract
This article explains how to extract SQL Statements found in Execute SQL Tasks of an SSIS package and save them into an Excel Workbook using C# programming language.

Requirements

• Microsoft Visual Studio 2008

Article
This article continues from another article which can be found here.
Launch Visual Studio 2008 and create an Integration Services Project. After the default (new) package has launched, drag a script task to the control flow pane.
Right-click to edit the script task. In your Script Task Editor ensure that you have selected Microsoft Visual C# as your programming language.
At the bottom of your Script Task Editor, click “Edit Script”.
The next step is to insert references.
In the Project Explorer, right-click “References” and click “Add Reference”. Click the “COM” tab and Choose Microsoft Excel 14.0 Object Library.
Add the following namespaces:
using Microsoft.Office.Core;
using Microsoft.Office.Interop.Excel;
The rest of the references should be declared as follows:
using System;
using System.Data;
using System.Data.Sql;
using System.Data.SqlTypes;
using System.Data.SqlClient;
using Microsoft.SqlServer.Server;
using Microsoft.SqlServer.Dts.Tasks;
using Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using RuntimeWrapper = Microsoft.SqlServer.Dts.Runtime.Wrapper;
using System.IO;
Proceed to load the package (that contains the Execute SQL Tasks you would like to extract and save).
Application app = new Application();

Load package
Package p = app.LoadPackage(“C:\\TEMP\\pkg_Execute_Sql_Tasks.dtsx”, null);
Declare variables that will be used to store extracted queries:

string src_query = “”;
string sql_task_name = “”;
Int32 i = 1;
Create an instance of an excel application as follows:

Excel.Application sS_excelApp;
Excel.Workbook sS_excelWorkBook;
Excel.Worksheet sS_excelWorkSheet;
object misValue = System.Reflection.Missing.Value;
sS_excelApp = new Excel.ApplicationClass();
sS_excelWorkBook = sS_excelApp.Workbooks.Add(misValue);
sS_excelWorkSheet = (Excel.Worksheet)sS_excelWorkBook.Worksheets.get_Item(1);

// Create Headings
sS_excelWorkSheet.Cells[1, 1] = “src_query”;
sS_excelWorkSheet.Cells[1, 2] = “sql_task_name”;

The rest of the code is as follows:
foreach (Executable executable in importPackage.Executables)
{
DtsContainer container = (DtsContainer)executable;
if (executable.GetType().Name == “TaskHost”)
{
i = i + 1;
TaskHost loop = (TaskHost)executable;
ExecuteSQLTask sqlTask = (ExecuteSQLTask)loop.InnerObject;
src_query = sqlTask.SqlStatementSource;
sql_task_name = container.Name;
string source = src_query;
string[] stringSeparators = new string[] { “GO” };
string[] result;
result = source.Split(stringSeparators, StringSplitOptions.None);
foreach (string s in the result)
{
// Insert new records into the workbook
sS_excelWorkSheet.Cells[i, 1] = s;
sS_excelWorkSheet.Cells[i, 2] = sql_task_name;
}
}
}
// Save the workbook
sS_excelWorkBook.SaveAs(“C:\\TEMP\\selectSIFISO_Book.xls”, Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
// Close workbook
sS_excelWorkBook.Close(true, misValue, misValue);
sS_excelApp.Quit();

Dts.TaskResult = (int)ScriptResults.Success;
We then save the package in a file system.
SIFISO_app.SaveToXml(“C:\\TEMP\\pkg_Execute_Sql_Tasks.dtsx”, dyna_pkg, null);
Conclusion
It’s that simple!
You can now execute your script task and the package will be created in the location you specified.
