Query date time

I am writing a function to extract date, where my Col1 consists of date and time and my Col2 consists of date only.

=query({Sheet4!A1:Q},”select Col1, Col2 where Col1 = date ‘”&TEXT(today(),”yyyy-mm-dd”)&”‘ or Col2 = date ‘”&TEXT(today(),”yyyy-mm-dd”)&”‘“)

Now, I am facing issue to extract Col1 properly as it misses out some and only extract some of the cells with today’s date.
