Where clause in query

I am trying to pull a query with 4 paramenters:

1.) Booked is "No" (this is a yes/no data type with a check option, need this not to be clicked)
2.) ReachoutRandom is "Yes" (again a yes/no data type with check mark, need this to be checked)
3.) Finished is "No" (this is a yes/no data type with a check option, need this not to be clicked)
4.) CallBackDate is Today's date or earlier-- ie: yesterday, day before, etc. (this is a date field)

Thanks!

Well, generally, with Yes/No fields, you would set your criteria equal to 0 (No, False, unChecked) or -1 (Yes, True, Checked)

so, your where clause would look like:

WHERE [Booked] = 0 AND [ReachoutRandom] = -1 AND [Finished] = 0 AND [CallBackDate] <= Date()
0

If null is allowed, you need to consider that in your where clause and decide if null is equivalent to no.  So, you might need to expand the logic to:

WHERE Nz([Booked],0) = 0 AND [ReachoutRandom] = -1 AND Nz([Finished],0) = 0 AND [CallBackDate] <= Date()
0
