+## SQL Delete Statement
+
+To delete a record in a table you use the `DELETE` statement. 
+
+Be careful. You can delete all records of the table or just a few. Use the `WHERE` condition to specify which records do you want to delete. The syntax is:
+
+```sql
+DELETE FROM table_name
+WHERE condition;
+```
+
+Here is an example deleting from the table Person the record with Id 3:
+
+```sql
+DELETE FROM Person
+WHERE Id = 3;
+```
+
+Using DELETE to remove all records from a given table 
+
+```sql
+DELETE * FROM Person
+;
+```
+
+Or depending on your RDBMS you could use the TRUNCATE TABLE statement which deletes all records from a table and depending on your RDBMS may or may not allow rollback.  DELETE is DML and TRUNCATE is DDL.
+
+```sql
+TRUNCATE TABLE Person;
+```
