Used for deleting rows from a table.
DELETE FROM table WHERE column1=value1;
DELETE FROM table WHERE column1=value1 AND column2=value2;
- Not specifying which records to delete will result in every record being deleted
- The same can be achieved with 'DELETED * FROM table'
- This process cannot be undone
- Not to be confused with DROP, for deleting columns and tables.
