I need to create a visualization that includes data from three or more tables that are all within one database.
I've been able to join two tables together, but don't know how to pull in data from a third table. How do you join data from three tables in tableau?
To make this join, I'd have two join clauses. The first would link Tables 1 & 2. The second join clause would like tables 2 & 3.
To make this question really clear, here's an excel sheet showing what I'm trying to do.
Thanks for the help,
You can just join 3 tables like you join 2 tables in tableau, by just dragging and dropping and defining the joins.
I copy pasted your tables into seperate sheets in excel as it was easier than creating a DB from it but the principle stays the same:
Hope that helps
