Parsing XML with SSIS transformation script

Osama Assaf — Thu, 14 Oct 2010 09:33:32 +0000

The ssis query component runs a query on the database and return the XML data in text

The transformation script will read the input row, parse the blob ito string and then parse the XML data embeded within the text

Dim xml String As String= System.Text.Encoding.ASCII.GetString(Row.MESSAGE.GetBlobData(0, CInt(Row.MESSAGE.Length)))

Dim sr As New System.IO.StringReader(xmlString)

Dim doc As New Xml.XmlDocument doc.Load(sr)

Dim reader As New Xml.XmlNodeReader(doc)

While reader.Read() Output0Buffer.AddRow()

If reader.Name = “TagName” Then

Try

Output0Buffer.PRECORDID = reader.GetAttribute(1)

SSIS Deployment Utility

Osama Assaf — Tue, 19 May 2009 13:16:58 +0000

To create an SSIS package deployment, use the properties on the SSIS project

Once theCreateDeploymentUtility option is selected (True) and the project is rebuild, a wizard file is created in the \bin folder which can be excuted and will proceed.

Writing to an SSIS variable within a dataflow script component

Osama Assaf — Thu, 31 Jan 2008 09:32:39 +0000

Use PostExecute() method to write to an SSIS variable within a script component.

Public Overrides Sub PostExecute()

Dim dtsVariables As IDTSVariables90

VariableDispenser.LockOneForWrite( “Error”, dtsVariables)‘ set error’s state

dtsVariables.Item(0).Value = errorsEnd Sub

Using expressions for task precedence constraint

Osama Assaf — Tue, 10 Jul 2007 11:11:46 +0000

When using a variable in evaluating a precedence constraint, the variable should start with @, e.g. variable User::Count should be refered to as @Count

Explicit transactions using SSIS

Osama Assaf — Thu, 21 Jun 2007 22:35:36 +0000

To use explicit transactions in SSIS the database connection option RetainSameConnection should be set to True. This allows all transactions to run in the same connection

Changing SSIS Variable value while executing a package

Osama Assaf — Fri, 25 May 2007 10:55:14 +0000

To change the value for an SSIS Package while executing use the “Set Values”.

Add a property path for the variable (You could also use it for other objects, e.g. loop counter).

Property Path : Package.Variables[VariableName].Value

Variable Mapping for SSIS data source

Osama Assaf — Fri, 25 May 2007 10:24:17 +0000

To map a TSQl variable with an SSIS variable, “?” is used as the variable in the SQl command or ifora parameter when calling a procedure.

Then, on the data source select parameters (each “?” will show up as parameter0, parameter1,..), and simply map it to any variable created in SSIS

Calling C# Assembly from SSIS Script Task

Osama Assaf — Thu, 24 May 2007 16:09:49 +0000

To call a C# assembly from an SSIS Task you need to do the following:

1- Build the C# with strong naming ( SDK Command :>sn /K c:\key.snk, add the Key.snk to the project and use it to sign it)

2- Add the Assembly to the CAG (VS Command:>gacutil /i AssemblyName.dll)

3- Copy the assembly to the “C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727″ folder for the Develpment or Production server

4- Form the SSIS Script designer, add the reference as it should appear in the list.

5- Import the library and instentiate an object to be used for the task

Imports System

Imports System.Data

Imports System.Math

Imports Microsoft.SqlServer.Dts.Runtime

Imports SQLReportingServices.SQlReportingServices

Public Class ScriptMain

Public Sub Main()

Dim SqlServer As String

Dim FileName As String

Dim FolderName As String Dim WhenUploadedName As String

Dim MiMe As String

SqlServer = http://ServerName/reportserver/reportservice2005.asmx

FileName = “c:\ExcelSheet.xls”

FolderName = “/Reports”

WhenUploadedName = “Data Sheet.xls”

MiMe = “Excel”

Dim SqlReportingService As SQLReportingServices.SQlReportingServicesSqlReportingService = New SQLReportingServices.SQlReportingServicesSqlReportingService.CreateResource(SqlServer, FileName, FolderName, WhenUploadedName, MiMe)

Dts.TaskResult = Dts.Results.Success

End Sub

End Class

SSIS Variables Scopes

Osama Assaf — Wed, 08 Nov 2006 11:38:33 +0000

When using an SSIS variable, the scope for that variable should be the package scope so it can be used by all the containers in the package (The Package Scope Variable is a Global Variable)

Fail to execute store procedure in OLE DB Source in Data Flow

Osama Assaf — Tue, 07 Nov 2006 11:23:45 +0000

When using SSIS for SQL 2005, running an SQL Command (Procedure) using an OLEDB Object may cause this error to trigger.

Use “SET NOCOUNT ON” in your procedure code to eleminate this error
