Difference between Statement PreparedStatement and CallableStatement
Statement PreparedStatement and CallableStatement are interfaces of JDBC that are used to interact with the Database, either to execute the insert’s, updates, deletes or to call a stored procedure or to get data. Lets see the difference between Statement PreparedStatement and CallableStatement.
