What are the different types of joins in Tableau?

Answer»

Tableau is pretty similar to SQL. Therefore, the types of joins in Tableau are similar:

  • Left Outer Join: Extracts all the records from the left table and the MATCHING rows from the RIGHT table.
  • Right Outer Join: Extracts all the records from the right table and the matching rows from the left table.
  • Full Outer Join: Extracts the records from both the left and right tables. All UNMATCHED rows go with the NULL value. 
  • Inner Join: Extracts the records from both tables.
