Thanks Prashant, just trying the Greenplum ODBC driver from Data Direct site. Just peculiar that my version works and I didn't do anything
I'll let you know once we've installed, I'm sure this should fix things - thanks for such a speedy reply!
i'm pretty sure that Tableau installs the driver in the background. IDK why they couldn't tell you that since it's what you experienced. I'm also not sure why it doesn't always happen.
