SSRS 2016: Great and Getting Better

Although I’ve been a regular user of SQL Server Reporting Services since it was released in the mid-2000s, I’ve done very little blogging about it. In fact, a quick search on my blog reveals that it has been almost five years since I wrote an SSRS-specific blog post. But let’s… Read more

SSIS Execution Status Lookup

The SSIS catalog comes packaged with a rich set of built-in reports that give those monitoring Integration Services a window into what has been happening inside the catalog. However, if you work with SSIS long enough, you’ll eventually need to write your own queries against the underlying tables. Of the… Read more

Zip Files in SSIS

Of the very many things SQL Server Integration Services does well, one of its shortcomings is that it does not have a built-in way to create compressed archive (ZIP) files. Generating such files is a common need in ETL processes, so it’s surprising that the fifth generation of SSIS still… Read more

SSIS Package Validation in the Catalog

Built into the SQL Server Integration Services catalog is the ability to run a validation without actually executing the package. Running a package validation in the SSIS catalog performs a high-level check against the underlying metadata to check for common points of failure (especially those related to data flows).

SSIS Data Taps

One of my favorite testing features of SSIS is also one of the most underutilized. SSIS data taps were introduced with the SSIS catalog in SQL Server 2012 as a way to capture data within one leg of a data flow task and write it out to a file for… Read more

A Shortcut for Parameterizing Settings in SSIS

I’ve written quite a bit about the benefit of externalizing changing values in SSIS packages. Moving static values such as connection strings and file paths to a configurable input makes easier the tasks of testing, changing, and auditing the process in the future.

On Being Disruptive

Being disruptive is a powerful way to conduct business. Steve Jobs and Bill Gates insisted that computers belonged not just in business offices but in the homes of regular joes, and built businesses around a need that had not fully manifested itself.
