  Define Join Conditions:
  
  Go to the "Join" tab or section in the Query Designer.
  Select the fields that will serve as the join condition. This typically involves selecting key fields that exist in both data sources.
  Ensure that the fields you select are compatible in terms of data type and semantics.
  
  
  
  Validate the Join: After defining the join conditions, validate the join to ensure that it is correctly set up. Look for any warnings or errors that may indicate issues with the join.
  
  
  Save and Test: Once you have defined the join conditions, save your changes and test the query to ensure that it runs without errors.
