Data - Anti join is a simple way to find what is missing.  In SQL, you can use LEFT JOIN with IS NULL to return rows from one table that have no matching row in another table.  Example:  Customers table → all customers Orders table → customers who ordered Anti join result → customers who have not placed any orders  The key pattern:  LEFT JOIN keeps all rows from the left table WHERE right_table.id IS NULL keeps only the unmatched rows  Useful for finding missing orders, unsold products, inactive users, or records that do not exist in another table.  Save this for your SQL problem-solving toolkit.  #SQL #SQLTips #AntiJoin #DataAnalysis #Database #DataCleaning #DataDrivenInsights | Facebook
