About the Join Tool

The Join tool combines the output from two separate steps of your analysis into one based on configurable matching criteria.

Add a Join tool

1. Navigate to your analysis.

2. Click this icon.

3. Click Join.

👉 Note: You may need to manually connect the second table to the second input node of the Join tool.


Configuration

  1. Add a Join tool to your Canvas.

  2. Select the type of Join you want to perform. Savant offers four types of joins: Left Join, Inner Join, Outer Join, and Cross Join.

  3. Since the Join Tool does not have a specific left input, users can decide which table input they want to act as the Left Table for the join operation.

  4. To perform a join, configure the Rules for matching records between the two tables. Use the dropdowns provided for each table input to select the columns you want to join on and the operator to use for the join condition.

  5. Adding Multiple Join Conditions: If needed, you can add multiple join conditions by clicking the "Add" button below the join conditions. Set the appropriate AND, or OR operator as necessary.

  6. Click Apply.
