Say it aloud for yourself in English...
'Please select me the date from the table BreakFast where EPF_Number'...
Where EPF_Number, what?
Where clause is incomplete as there is no actual condition in it...
In any other aspect too you query is wrong - check
CONVERT function[
^] of SQL to see what parameters it gets...
You also mentioned a need for order, but no ORDER BY clause in your query of any kind...
(If I try to make any sense of your request, you should have some query like this:
SELECT EPF_NUMBER FROM BREAKFAST ORDER BY DATE)
