I have a timestamp field and I want to select all of yesterday's transactions. If I hardcode the statement as:
TTMSTMP > '2017-05-08-00.00.00.000000'

I get what I want but I have to edit every day. How can I compare a timestamp field for beginning of yesterday?
WHERE ttmpstmp > current_timestamp - 1 DAY
This only pulls for the last 24 hours and does not get all of yesterday.
