Hi Shruthi, Tableau join is a plain SQL join and acts the same way as it does in the SQL. However talking about Blend its an amazing feature of tableau. While using Joins your data gets joined immediately and rows are matched to each other on row level as per the join type and condition, however while using Tableau Blend it acts a bit different, tableau blend only works as Left Join and the data blended post aggregation. The data will be coming from both the sources will be first aggregated and then it'll be blended together. None of these processes are deployed by default.

No need of giving join condition in blending? will tableau select join condition by default... if it so can we change the join condition?
