Getting Anatomical With SSIS Catalog Compare

Published 2018-09-04 by Kevin Feasel

Andy Leonard shows off parts of SSIS Catalog Compare.  First up is the catalog reference script:

As you may glean from this analysis of one script generated for SSIS Catalog References management, the Transact-SQL for scripting SSIS Catalog artifacts in SSIS Catalog Compare is rigorous and includes several existence and error-condition checks prior to performing any updates. The script is designed to be idempotent, as well, meaning the script will succeed and the results will be repeatable and predictable each time the script is executed – and that the script itself is re-executable.

Then an environment script:

The final portion of the script checks for the existence of the Environment Variables and responds accordingly. This is a three-step process:

  1. Drop the Environment Variable if it exists.
  2. Create the Environment Variable.
  3. Set the Environment Variable value.

If the Environment Variable exists the script drops it. Why? SSIS Catalog Compare wants to be sure the environment variable is created with the proper data type and initial values.

And connection literals:

These messages are intended to be copied and stored in the Notes field of a ticketing system in a DevOps enterprise. Note the detail contained herein:

  • Script Name – the path to the file used to perform the operation.

  • Generated From – the SQL Server instance of the SSIS Catalog host from which the script was generated.

  • Catalog Name – redundant at present because all SSIS Catalogs are named “SSISDB.”

  • Folder Name – the name of the SSIS Catalog Folder that contains the scripted artifact.

  • Project Name – the name of the SSIS Project that contains the scripted artifact.

  • Project Connection Name – the name of the SSIS Project Connection.

  • Generated By – the name of the enterprise account used to generate the artifact’s script.

    • Note: SSIS Catalog Compare respects the security model of the SSIS Catalog. Windows Authentication is required to perform many SSIS Catalog operations.

  • Generated Date – the date and time the script was generated.

  • Generated From – the version of CatalogBase used in the generation of the artifact script.

    • Executing On – the name of the machine on which CatalogBase was running.

  • Deployed to Instance – the SQL Server instance hosting the target SSIS Catalog.

  • Deploy Date – the date and time the deployment script was executed.

  • Deploy By – the enterprise account used to deploy the artifact script.

Andy has put a lot of thought into SSIS Catalog Compare, so go check it out.

Power BI Without Active Directory

Published 2018-09-04 by Kevin Feasel

Ginger Grant shows us how we can expose Power BI dashboards without needing users to have Power BI or Active Directory accounts:

There are many companies which would like to provide Power BI reports which would allow customers to interactively work with their data, but they don’t want to create Power BI accounts for customers as that can be a lot of work from an administrative standpoint.  For the same reason, these customers are not added to the corporate network which means they are not added Active Directory.  For example, if Desert Isle SQL contracts with Acme Corporation to create a custom conference display, Acme might want to show me a report showing when the components were purchased, when they were modified and when the order is in process and when the order is completed.  How do I show a Power BI report containing information? From an application design perspective data from all of the customers should be stored in the same place and Desert Isle SQL should only see their orders when logging in to Acme’s site.

Ginger also covers a bit about the licensing cost of going down this route.

Burndown Charts In Power BI

Published 2018-09-04 by Kevin Feasel

Paul Turley shows how to create burn-down and Pareto charts in Power BI:

I’m managing an Agile team project using Microsoft Teams – the new project management platform integrated with Office 365.  Teams is a simple and useful project management tool but it’s new and light on features.  Using Power BI, we want to show the hourly task burn-down for each two-week sprint.  In JIRA and some other more mature project management platforms, the burn-down chart is a standard feature in the tool that shows the number of hours or story points remaining, compared to the estimated number for the sprint.  Just as I began working on that, a client asked for some help creating a Pareto chart and it occurred to me that burn-down and Pareto charts are very similar variations of the same type of chart presentation.  These are not so much chart types as they are a set of calculations and techniques for displaying a desired result.

Finding Gaps In Identity Columns

Published 2018-09-04 by Kevin Feasel

Shaun J Stuart walks us through a couple of solutions for finding gaps in identity ranges:

Have you ever had random inserts into a large table fail? Most of the time, inserts happen fine, but every so often you get a failure with a “primary key violation” error? If your primary key is an integer column with the identity property, you may be wondering how this is possible.

What is likely happening is your table has grown very large or has been in use for a long time and your identity column ran out of numbers. An integer column has a maximum value of 2,147,483,647. Now an integer can start at -2,147,483,648, but most people  start at 0 or 1, so that leaves you with 2 billion numbers.

This is a specific sub-case of the more general gaps and islands problem.
