Why do you want to query backend tables when TA could provide all the data to you out of box.
Anyways here is the SQL (table info below) from the transaction analysis for Date Received (as Today selection)
SELECT
d.DocID,
d.DocTimestamp,
t.TypeName,
s.CorporationName AS SenderCorp,
s.OrgUnitName AS SenderUnit,
r.CorporationName AS ReceiverCorp,
r.OrgUnitName AS ReceiverUnit,
d.RoutingStatus,
d.UserStatus,
d.NativeID,
d.GroupID,
d.ConversationID
FROM
BizDocTypeDef t,
Partner s,
Partner r,
BizDoc d
WHERE
d.DocTypeID = t.TypeID AND
d.SenderID = s.PartnerID AND
d.ReceiverID = r.PartnerID
AND d.DocTimestamp > {ts ‘2013-08-29 00:00:00.0’} AND
d.DocTimestamp < {ts ‘2013-08-30 00:00:00.0’}
ORDER BY d.DocTimestamp DESC
