Grouping Date Field By Day Only, Not Time

I'm adding up quantities of an item that are entered in one after another, so the date is the same, but the time differs.

I used the "first" function in access which works the way I want, but sql7 doesn't use the same function. The "convert" function does not work in access but Here is the gist of the query:

SELECT first(CONVERT(varchar,transactions.tran_date,101)) AS [trandate], transactions.tran_type,
SUM(transactions.qty) AS totqty,...etc.

thanx,
