In this article, I will first give an overview of the OLE DB, ODBC, and ADO.NET SSIS connection managers. Then I will try to illustrate the difference between them when trying to connect to SQL Server.

In this article, I will first give an overview of SSIS data types and data types conversion methods and then I will illustrate the difference between changing the columns data types from the Source Advanced editor and using Data Conversion Transformation.

In this article, we will first give an overview of SSIS derived column transformation, then we will run an experiment to check if there is any difference between adding multiple expressions within one derived column transformation and adding a derived column transformation for each expression.

In the previous article, I gave an overview of Execute SQL Task in SSIS and we illustrated some of the differences between writing an expression to evaluate SqlStatementSource property and writing this expression within a variable and change the Execute SQL Task Source Type to variable.

In this article, I will give an overview of Execute SQL Task in SSIS and I will try to illustrate some of the differences between writing an expression to evaluate SqlStatementSource property or writing this expression within a variable and change the Execute SQL Task Source Type to a variable.

In this article, I will give an overview of SSIS OLE DB Destination and SQL Server Destination and I will try to illustrate some of the differences between both destination components based on my personal experience, SSIS official documentation and some other experts experience in this domain.

In this article, I will first give an introduction about SSIS expressions, then I will describe briefly the Expression Task and how to Evaluate a variable as expression. Then I will do a comparison between these two features to illustrate the similarities and differences between them.

Introduction

SQL Server Integration Services provides a wide variety of features that helps developers to build a robust Extract, Transform, and Load process. After many years contributing to SSIS-related tags on Stackoverflow.com, I can say that many developers have some misunderstandings about SSIS features (SSIS OLE DB Source, SSIS Expressions, SQL Server destination …) especially those which are very similar and have some common usability.
