Errata for Oracle PL/SQL Programming

On page 582 of this book, near the top, it says that an OUT parameter is Write-only. This is incorrect; An OUT parameter can be read as well as written to, as a simple test will prove. On the next page, 583, it says "You cannot assign an OUT parameter's value to another variable or even use it in a reassignment to itself." This too is incorrect. You can assign the parameter's value to another variable -- once again, as a simple test will prove. This procedure works: PROCEDURE Parse_HC (p_timestamp_string IN VARCHAR2, p_timestamp_date OUT DATE) AS v_date DATE; BEGIN p_timestamp_date := TO_DATE(p_timestamp_string, 'YYMMDDHH24MI'); v_date := p_timestamp_date; END Parse_HC;
