DELETE FROM table_name WHERE condition;
- Example:
DELETE FROM employees WHERE department_id = 10;
- Characteristics:
- Can use WHERE clause to filter which rows to delete.
- Generates row-level locks.
- Deletes one row at a time, which can be slower for large tables.
- Can be rolled back if used within a transaction.
- Triggers, if defined, will be fired.
TRUNCATE:
- Purpose: Removes all rows from a table, resetting it to its empty state.
- Usage: Used when you need to quickly remove all data from a table.
- Syntax:
TRUNCATE TABLE table_name;
- Example:
TRUNCATE TABLE employees;
- Characteristics:
- Cannot use WHERE clause.
- Faster than DELETE as it deallocates the data pages instead of row-by-row deletion.
- Resets any AUTO_INCREMENT counters.
- Cannot be rolled back in some database systems as it is a DDL operation.
- Does not fire triggers.
DROP:
- Purpose: Removes an entire table or database from the database.
- Usage: Used when you need to completely remove a table or database structure.
- Syntax:
DROP TABLE table_name;
DROP DATABASE database_name;
- Example:
DROP TABLE employees;
- Characteristics:
- Permanently deletes the table or database and all its data.
- Cannot be rolled back; once dropped, the table or database is gone.
- All indexes and triggers associated with the table are also deleted.
- Removes table definition and data.
Tip: Use DELETE when you need to remove specific rows and want the option to roll back the transaction. Use TRUNCATE when you need to quickly clear all data from a table without deleting the table structure itself. Use DROP when you need to completely remove a table or database structure and all associated data permanently. Always ensure you have backups and understand the impact of these operations before executing them.
