'Today' looks for all dates <= ' 00:00:00' so any dates with that date and a time later than midnight will not meet your criterion. If you want all dates that have 'today's date' then your query must ask for

WHERE docdate > 'yesterday' and docdate < 'tomorrow'
WHERE docdate BETWEEN 'yesterday' AND 'tomorrow'.
