Date Control Problem

Dear Sir / Madam, Case 1: My database, Table name -> Test. Field name -> due_date. Let say, due_date = 2001-01-01. Now, I would like to display all data from Test table where my due_date is before the current date. I tried the below SQL statement but it didn't work, SELECT * from Test where due_date >= curdate(); My display result should be zero. Any good solutions or suggestions for Case 1? Case 2: My database, Table name -> Test. Fields name -> posting_date, and expired_day. Let say, posting_date = 2000-12-20 expired_days = 14 days So my due date is 2001-01-02(from my own calculation). Same as case 1, I would like to display all data from Test table where expired_day plus posting_date is before the current date. My display result should be zero. Any good solutions or suggestions for Case 2? Thanks in advance. Best Regards, Ian.
