问题 Is it possible to write a custom SQL query in tableau performing left outer join where one of the table is in the database which is a MySQL Database type and second table is in Oracle database kind.

问题 How do I realize the following set difference/group distinction task in Tableau Desktop? I have products who have either been adjusted or not ( adjusted = 1 or adjusted= 0 ). Note that each product might be listed more than once (as the real dataset is a a matrix of stacked time series for each product). I would like to find out how many products had at least one adjustment and how many had none. This is how would do it in R: Example data: dat <- data.frame( product = c("4005808588763",

问题 Tableau recently expanded some tools for developers to Linux, from Windows-only. After downloading the Tableau Data Extract API libraries for Python (2.7) on Linux (64Bit, version 8.1), I extracted the files and installed the libraries using the standard 'python setup.py install' When trying to run with a code that works on Windows, I get the following error: Traceback (most recent call last): File "apache.py", line 280, in <module> print create_tableau(tsvfile) File "apache.py", line 136, in

问题 Is there any way to connect Tableau Desktop to plain Apache Hbase or plain Hive ? I could only find Tableau drivers for Hortonworks/ MapR/ Cloudhera etc. 回答1: Install drivers in desktop installed machine. You can't directly connect to hbase table via tableau you need to connect to hive table and hive internally mapped to hbase table. follow links http://thinkonhadoop.blogspot.in/2014/01/access-hbase-table-with-tableau-desktop.html http://grokbase.com/t/cloudera/cdh-user/141px9aqg5/hbase

问题 I have an incident queue, consisting of a record number-string, the open time - datetime, and a close time-datetime. The records go back a year or so. What I am trying to get is a line graph displaying the queue volume as it was at 8PM each day. So if a ticket was opened before 8PM on that day or anytime on a previous day, but not closed as of 8, it should be contained in the population. I tried the below, but this won't work because it doesn't really take into account multiple days. If

问题 Given a PivotTable in Tableau, is there a way to know the associated MDX Query? I would help my understanding current pivot table and fix potential misconstructions. 回答1: Unlike ProClarity and some other MDX-generating tools, you can't see the MDX being created while in the UI. However, if you open up the \My Documents\My Tableau Repository\Logs folder, you'll see Desktop's logs. You can open those up and see each and every MDX statement that has been executed against SSAS. Hope this helps!
