SQL: How to compare dates while ignoring the time? -


how can compare dates of timestamps while ignoring times?

i want compare month/date/year. example:

select * batch openingtime <> closingtime

the problem show many batches, since include batches openingtime , closingtime differ in time of day:

openingtime = 2010-07-07 11:19:29.000

closingtime = 2010-07-07 19:19:22.000

cast both timestamps dates

for sql server

select *  batch  cast(openingtime date) <> cast(closingtime date)

for oracle

select *  batch  trunc(openingtime) <> trunc(closingtime)
