DELETE Statement

The DELETE statement is used to remove records from a table. You can specify which rows to delete using the WHERE clause.

Examples of Using DELETE

Scenario 1: Deleting a Single Record

DELETE FROM FreedomFighters
WHERE Name = 'Durai';

Output:

Record for Durai deleted successfully.

Scenario 2: Deleting All Records

DELETE FROM FreedomFighters;

Output:

All records deleted from the FreedomFighters table.

Do's and Don'ts

Do's

  • Use a WHERE clause to delete specific records and prevent accidental data loss.
  • Back up the table before performing a delete operation on important data.
  • Use transactions when deleting multiple records to ensure data integrity.

Don'ts

  • Don't use DELETE without a WHERE clause unless you intend to clear the entire table.
  • Don't delete data without confirming dependencies or relationships with other tables.
  • Don't perform delete operations on large datasets without performance optimization.
