I have 3 custom SQL's , they are all same queries but due to some filter conditions , i need to separate them into 3 custom SQL's rather than a single Custom SQL,. Is it possible to Union these 3 custom SQLs in tableau  Desktop?  They are from  the same database connection. Thanks

I've installed Tableau Desktop free trial and I would like to get the file in order to follow along the sample Excel file used for this Trail  

Thanks in advance it is about furnitures (office, etc;;;) 

I get the error "An error occurred while communicating with the data source all inputs to union must have matching column types" when running my flow. I was using it without problems all 2024, but now I modified it because I had a date filter (show only 2024) that I needed to update. I even rolled back my filter but keep getting the error. Talked to the DB administrator and he says they haven´t made any changes to sources (variable names, columns, DB types). Is it a known error? Please help.

PS: I get the error in desktop and in web.

I've noticed that the values in a Pivoted Fields (Rows to Columns) function does not refresh its values to pivot on when the underlying data changes. I have a monthly dataset update that I need to pivot on the month field. I always have to remove the selected column and add it again for the function to correctly read the new values. Is this a bug? 

Hi Tableau Community,

I’m experiencing some challenges in combining data to create a hyper file, as I believe this would simplify the process of updating a 3-line chart with a new Excel worksheet each month. In Tableau Prep, one of the worksheets contains a unique column that differs from the others, which I need to retain for comparison purposes. However, when I connect it to Tableau Desktop, the data doesn’t read correctly.

Additionally, I’ve created a bar chart to compare the total number of documents (Actual Submission Total and Publish Date Total). However, it appears a bit unusual because all the months are displayed, which I suspect is due to the way the data is structured.

Could you please assist me with both of these issues?

Thank you! 

It seems like E-A-V architecture makes a lot of sense for our data, as different events have different properties, but I haven't worked with E-A-V database in Tableau before. It seems like it would create a mess of Joins, or I'd have to have a pretty over-the-top flow in Tableau Prep to shape it. Searching forums it doesn't look like there's much on using Tableau with Segment,io or E-A-V in general.

Does anyone have any thoughts or experience? What Database architecture would you use if not E-A-V, or how did you manage E-A-V with Tableau?

Hello,

I can't edit any flow directly on the server, yet I am the owner of the flow. When I click the edit flow button, I have the running icon running forever. The only way for me to update my flows is to download them, edit them on desktop and then upload. Any solution ?

Thank you

I have used fields from Tableau Prep Output in Tableau Pulse to configure Custom Calendar.  

Since 'Day of Year', 'Week of Year', 'Month of Year', 'Quarter', 'Year' must be of INT data type for pulse custom calendar, I have kept these fields as INT in prep flow. But I guess these f

, hence I am not able to set-up custom calendar. How can I resolve this issue ? 

While in extract it is working perfectly as we can convert these fields to Dimensions!
