Good afternoon everyone,
I have a database with tables relating to invoices, customer
demographics, ect. Is there an operator that would allow me to query a set
number records (100 or so)from the invoice table randomly? We want random
records for internal audits and such. Thank you very much.

You can use the Top Values property of a query, with help
from a little VBA. Put this little function into a Module:

Public Function RndNum(vIgnore As Variant) As Double
Static bRnd As Boolean
If Not bRnd Then
'Initialize the random number generator once only
bRnd = True
Randomize
End If
RndNum = Rnd()
End Function

Then add a calculated field to your Query by typing

Shuffle: RndNum([fieldname])

in a vacant Field cell, where [fieldname] is any field in
your table - this forces Access to give a different random
number for each record.

Sort the query by Shuffle, and set its Top Values property
to the number of records you want to see.
