Ever worked on a quick little project, come across what you assume is a common need and think “I’ll just google up some code that someone else has written and then be off to the races”? Have you done this and not been able to find the code you’re looking for? Well, that was me […]
gah. Why is some of this stuff so challenging in Tableau? You have a date and you want to format it as a string? Why? So you can concatenate it with another string perhaps? Maybe you’re creating a calculated field to use in a label (that’s what I was doing). Unfortunately, when you convert a […]
For Tableau requirements like: Allow user to choose “Last 7 Days”, “Last 30 Days”, etc. this is your ticket. It turns out one parameter and one calculated field are all you need.
Suppose you create an extract in your desktop version of Tableau and everything is running great. Then one of your peers casually asks “how big is that .tde file anyway?” You quickly check file explorer and discover the extract is not in the default location (What is the default path?).

As soon as I saw this error message I guessed the problem was related to using a temp table. What was surprising was that the error message actually said this but I didn’t realize it until by chance I cut and paste the message into another window. Look below: Do you see the reference to […]
This is one scary looking error message: SSIS error 0x00084005 “the parameter type cannot be deduced because a single expression contains two untyped parameters @x and @P1” It’s terrifying enough to make you think maybe you should quit your SSIS development career altogether. But wait… What’s this? Perhaps you’re getting this message for the same […]
Dear SQL Server Integration Services Team, Would it be possible to get a more specific error message than “There are some mapping errors on this path”? Your friend, Phil The tricky problem with this error is getting enough information to troubleshoot it. Here’s a nice trick for you: Run the package. Wait. What? Why would […]
As more and more companies are moving to heterogenous environments with both windows and unix systems the life of the Microsoft SQL Server developer is becoming much more interesting. For our recent data warehouse project I was asked to create a SQL Server 2012 Integration Services (SSIS) ETL package to output a text file for […]
