Mixed Format Data Files

Using the SSIS Object Variable as a Data Flow Source

Object variables in SSIS are incredibly versatile, allowing the storage of almost any type of data (even .NET objects). In my last post on this topic, I demonstrated how an SSIS object variable containing a .NET DataSet object could be used by the for each loop container as an iterator. In this post, I’ll continue the discussion by showing how…

Mixed Format Data Files

Handling Mixed Format Data Files in SSIS

Some time back I wrote about how to use the script component to parse out ragged data files in SSIS. In this post, I’ll continue the discussion to describe how to handle mixed format data files – specifically, those with several different record types in each file. In a perfect world, a flat file will contain a single record type….

SSIS Training with Tim Mitchell

A full day with me, SSIS, and Edgar Allan Poe

When I think about Baltimore, I think about Edgar Allan Poe. Baltimore was Poe’s one-time home, and in fact there is a museum located in a home in which he once lived. I’ve been a Poe fan since high school, and am looking forward to seeing some of the Poe-related sights when I’m in town next month. Why am I…

Fix Inconsistent Line Terminators in SSIS

When processing data files using SQL Server Integration Services, it is not uncommon to find files with different end-of-line markers for each line in the file. In this post, I will demonstrate how to fix inconsistent line terminators in SSIS to avoid ETL errors. Fix Inconsistent Line Terminators in SSIS In every text file, there are unprintable characters called line…

Excel Worksheets with Biml

Iterating Through Excel Worksheets with Biml

Wrangling large or complex Excel workbooks in SSIS can be a challenge. From managing data types (more about that in this post by Koen Verbeeck) to addressing multiple worksheets in a single document, configuring SSIS to properly read from or write to Excel documents is tedious at best. While there are no silver bullets to completely solve these problems, I’ve…

This is the third in a series of posts about SSIS parent-child architecture.  You can find the index page here. In my previous posts on SSIS parent-child package architecture, I described the benefits of the parent-child package design pattern and demonstrated the implementation of such a pattern in package deployment mode.  In this post, I will demonstrate the parent-child pattern…

Parent-Child SSIS Architecture

Parent-Child SSIS Architecture

This is the first in a series of technical posts on using parent-child SSIS architecture.  In this post, I will provide an overview of the architecture and describe the benefits of implementing a parent-child design pattern in SQL Server Integration Services structures. Parent-Child SSIS Architecture The simplest definition of SSIS parent-child architecture is that it consists of packages executing other…
