i have parameters start date and end date. if the user doesn't enter any value, default value for end date is null. with start date, is the most logical thing to do is to get the earliest date from the database? i'm querying from 3 big tables, this might slow down the process. thanks!

I suggest using either 1901 or 1801 as your year. Using 0001 has issues when you come to do the number of days between particular dates. Most calendars changed by around 16 days between the mid-1500s and the mid-1600s. NEVER use 0000 as a year as it did and does not exist.
