Allow non-administrators to install Tableau Reader

tableaucommunity@tableau.com — Wed, 17 Apr 2013 23:57:56 GMT

Tableau marketing often makes the comparision of Tableau and Tableau Reader with Adobe and Adobe Reader. There is one important difference - anyone can install Adobe Reader, but only those with administrator privileges can install Tableau Reader. Many organisations limit admin priviledges, and in our case, charge us when we use IT to provide installation services of this type.

Of course this limits our use of Tableau, because we can't encourage our users to install Tableau Reader, and if customer satisfaction is not sufficient driver for Tableau, of course it limits the degree to which we expose our organisation to Tableau and consequently the opportunities for selling further copies of the full package.

Seems like win/win.

Error "permission denied for relation events" when trying to use data from a postgres database

tableaucommunity@tableau.com — Wed, 27 Mar 2019 17:04:44 GMT

Newbie for this kind of material, but we have been using data from one multi-table postgres database on a single table basis, without problems for a considerable period. I now have another postgres database, with only two tables, and when we use a single table, no values are plotted, and when I open the error message I get ERROR: "permission denied for relation events".

This probably betrays a massive ignorance of postgres databases, but I freely confess to just being a basic user.

ANy suggestions?

Thanks

Preserve recently used workbooks upon update

tableaucommunity@tableau.com — Wed, 17 Apr 2013 23:44:04 GMT

Along with others commenting on some of the rather archaic features of Tableau upgrades, I'd like to see that the recently used worbooks tab was also carried forward during an upgrade. Can't think of any other program for which upgrades are a routine feature, where the recently used file list is erased, so unless there is some fundamental problem, this should be a "best practice" feature (although a minor one).

Merging two tables in a single dataset

tableaucommunity@tableau.com — Thu, 23 Aug 2012 23:17:07 GMT

Excuse what is probably a pretty basic question - just can't seem to come up with the correct approach.

I collect data from each individual as they use a database - ID, LogIn time, # of concurrent logins at that time, LogOut time, # of concurrent logins at logOut time; each is on a single row in an Excel table. In essence I have two tables, linked by the login ID, of pairs of (LoginTime) & (# at Login) and (LogoutTime) & (# at Logout).

What I want to graph, on a single time axis, is the # at Login or Logout. I can simply append one set of data to the other, but obviously this would require manual intervention, and I'm sure there are Tableau techniques that can do the task automatically

I'm not sure if this is a merging or a data blending issue. Thanks for any assistance.
