"A CallableStatement is the only way for a Java program to execute stored procedures in the database."
Maybe that's the intention ([2]), but I'm not convinced it is true.
If the stored procedure doesn't have an output parameter you can use a PreparedStatement. If the stored procedure doesn't take any input parameters you can use a Statement - or maybe even build the call string with the parameters, which is not recommended for several reasons (security, performance, style).
Is the statement based on the API docs / specification, or on experience with a particular database system?
No big deal, but I didn't tick this option and failed the question
What do you think?Regards,
