SQLException when deleting

[Lieven De Keyzer]

This is a snapshot of my AccountSqlMapDao, following the concepts of the 
latest JPetStore.

 public void insertAccount(Account account) {
   insert("insertAccount", account);
 }
 public void updateAccount(Account account) {
   update("updateAccount", account);
 }
 public void deleteAccount(Account account) {
     delete("deleteAccount", account);
 }
I get an error however in deleteAccount:
unreported exception java.sql.SQLException; must be caught or declared to be 
thrown

[javac]     delete("deleteAccount", account);
Why do I need to catch the exception for the delete statement, but not for 
the insert or update method?
