Answer Posted / Vinika Choudhary
To insert a new record, use the INSERT statement with ON DUPLICATE KEY UPDATE clause. For example:nnINSERT INTO table_name (column_to_update) VALUES ('new_value') ON DUPLICATE KEY UPDATE column_to_update = 'new_value';nTo update an existing record, use the UPDATE statement with WHERE clause.nnUPDATE table_name SET column_to_update = 'new_value' WHERE condition;
