Hi all,

I need to know what is the most efficient way to get the following in vba

count of distinct dates for certain criteria.

for example, how many distinct dates are scheduled for this week.

two schedule records for Sunday are considered 1, while Sun, Mon, Tue are counted as 3.

I know I can do it in a saved distinct query and use DCount of that query, however wonder if that is the most efficient way of accomplishing it, as i am dealing with a very large table.

save the above query as QCount

open it as recordset

dim rs as dao.recordset, xCount as integer
set rs=currentdb.openrecordset("QCount")

xCount=rs!CountOfSchedules

Thanks allot Ray, that worked, however just wonder if the following approach would perform faster?
create a SQL function that accepts a int variable and returns a int, then have this function being called from the app.
p.s. its a ms access front end application linked to SQL Server back end.
