XML Source Task in SSIS
Suppose we want use a XML file as a data source for further processing on it’s data.

SSIS XML source is basically used when we want to read the data from XML files.
First you will have to create a SSIS Project.  You can refer post ‘How to Create SSIS Project?‘ to create this.
1. Now in the project, drag and drop the ‘Data Flow Task’ into control flow tab and double click on it. It will redirect you to  Data Flow Tab.
2. Drag and Drop the ‘XML Source’ from SSIS toolbox and double click on it. Below window will appear-

3. Now browse the xml file and click on ‘Generate XSD’.
What is XSD?
XSD (XML Schema Definition) is a W3C recommendation that defines the way to utilize the elements in an XML file.It specifies how to formally describe the elements in an Extensible Markup Language (XML) file.XSD can also be used for generating XML documents that can be treated as programming objects. In addition, a variety of XML processing tools can also generate human readable documentation, which makes it easier to understand complex XML documents.
Below window will open to save the XSD file. Click on Save.

4.  Now click on ‘Columns’, it will show the below Warning Message which is for length of the columns and System will automatically use DT_WSTR (lenght -255).
If you don’t want to use it, in this case you need to edit XSD file manually. In this case we are accepting the warning message and click on OK.

6. Now drag and drop a ‘Derived Column’ to preview the data and connect it with XML source using data path.
7. Now enable the data viewer and execute the package. Results will appear as below-

Scenario: We want to provide a way for users to easily see a summary of the current project tasks. We want them to be able to see the following information: Open Tasks Assigned to Them Overdue Tasks Tasks Due This Week Task Calendar Tasks Assigned to Others Solution: To build this solution we will be using several different tools available in SharePoint, all included in the list below: Task List Task List Views We will create views for each of the different ways we want to see the data displayed on our dashboard. Web Part Page List View Web Parts Custom Navigation The first thing we will do is create our task lists and then configure all the views that we need. To create the list, go to View All Site Content, Create and then select the Task list. Next, we will need to configure our custom views. To do this, w

MERGE transformation in SSIS

In this post we are gonna discuss about MERGE transformation. MERGE in SSIS is equal to UNION ALL in SQL Server. This transformation unions two datasets/tables.The merge Transformation combines two  sorted  dataset into single dataset. Highlighted the text SORTED in last statement because “It is not possible to use MERGE when the inputs are NOT SORTED”. There is one more transformation which is very similar to this i.e UNION ALL. The Merge Transformation is similar to the union all transformations. Use the union all transformation instead of the merge transformation in the following situations. The transformation inputs are not sorted The combined output does not need to be sorted. The transformation has more than two inputs. MERGE takes ONLY TWO inputs where as UNION ALL can take more than two. Now lets see how to configure MERGE transformation with an example. I created TWO tables with names MergeA and MergeB and inserted few records into each table as shown below.
