Google BigQuery Daily Imports Help

Hey,
So in BigQuery I've got a table full of data for each day:
app_events_20180201
app_events_20180202
etc. etc. what I'm trying to do is create a query in the connector that will simply run and append yesterdays data. I've been playing around with things like
select user_id
from app_events_DATE_FORMAT(current_date - 1, “%Y%m%d”)
or
from "app_events_"+"DATE_FORMAT(current_date - 1, “%Y%m%d”)"
but I can't seem to get anything to work. Has anyone else figured out a simple way to append each days data aside from going in everyday and changing the table name?

We just used regex in the query statement to find yesterdays table via the suffix and pull in all the data from it.
REGEXP_CONTAINS(_TABLE_SUFFIX, r'^\d{8}$') AND PARSE_DATE("%E4Y%m%d", _TABLE_SUFFIX) BETWEEN DATE_SUB(CURRENT_DATE(), INTERVAL 1 DAY) AND CURRENT_DATE()
