Depending on it you can convert it and compare

where cast(col as datetime) between datefrom and dateto

CONVERT(INT,GetDate()) give the date part of datetime rappresentation.
So my suggestion is to use CONVERT(DATETIME, CONVERT(INT,GetDate())).
Another advantage to integer cast versus string cast is that it’s simpler to use in ordering, filtering and so on (think about BETWEEN).

The convert function is rounding the value. So dates that has passed noon will become tomorrows dates — oops.

thus correct value would be:
Convert(Int, convert(float, GetUtcDate()))

Converting from float to int will truncate the value.

If you want to do it by sql, use

select datename(year,getdate())+’ ‘ +convert(varchar(6),getdate(),9)

SELECT * FROM mytablename ORDER BY cast(datefield as datetime) ASC

Also always use proper DATETIME datatype to store dates
