MySQL NATURAL JOIN

The NATURAL JOIN keyword automatically joins tables based on columns with the same name and data type in both tables. It simplifies join operations but requires careful handling to avoid ambiguity.

Example: Using NATURAL JOIN

SELECT *
FROM tamil_kings
NATURAL JOIN kingdoms;

Code Explanation: This query performs a natural join between tamil_kings and kingdoms, automatically joining on columns with the same name and data type.

Key Takeaways

  • NATURAL JOIN simplifies joins but should be used carefully to avoid unexpected results.
  • Ensure that the columns used for joining are named consistently in both tables.
