Need help translating this SQL query into SQLAlchemy:
select
COALESCE(DATE_1,DATE_2) as DATE_COMPLETE,
QUESTIONS_CNT,
ANSWERS_CNT
from (
(select DATE as DATE_1,
count(distinct QUESTIONS) as QUESTIONS_CNT
from GUEST_USERS
where LOCATION like '%TEXAS%'
and DATE = '2021-08-08'
group by DATE
) temp1
full join
(select DATE as DATE_2,
count(distinct ANSWERS) as ANSWERS_CNT
from USERS
where LOCATION like '%TEXAS%'
and DATE = '2021-08-08'
group by DATE
) temp2
on temp1.DATE_1=temp2.DATE_2
)
Mainly struggling with the join of the two subqueries. I've tried this (just for the join part of the SQL):
query1 = db.session.query(
GUEST_USERS.DATE_WEEK_START.label("DATE_1"),
func.count(GUEST_USERS.QUESTIONS).label("QUESTIONS_CNT")
).filter(
GUEST_USERS.LOCATION.like("%TEXAS%"),
GUEST_USERS.DATE == "2021-08-08"
).group_by(GUEST_USERS.DATE)
query2 = db_session_stg.query(
USERS.DATE.label("DATE_2"),
func.count(USERS.ANSWERS).label("ANSWERS_CNT")
).filter(
USERS.LOCATION.like("%TEXAS%"),
USERS.DATE == "2021-08-08"
).group_by(USERS.DATE)
sq2 = query2.subquery()
query1_results = query1.join(
sq2,
sq2.c.DATE_2 == GUEST_USERS.DATE)
).all()
In this output I receive only the DATE_1 column and the QUESTIONS_CNT columns. Any idea why the selected output from the subquery is not being returned in the result?
Not sure if this is the best solution but this is how I got it to work. Using 3 subqueries essentially.
query1 = db.session.query(
GUEST_USERS.DATE_WEEK_START.label("DATE_1"),
func.count(GUEST_USERS.QUESTIONS).label("QUESTIONS_CNT")
).filter(
GUEST_USERS.LOCATION.like("%TEXAS%"),
GUEST_USERS.DATE == "2021-08-08"
).group_by(GUEST_USERS.DATE)
query2 = db_session_stg.query(
USERS.DATE.label("DATE_2"),
func.count(USERS.ANSWERS).label("ANSWERS_CNT")
).filter(
USERS.LOCATION.like("%TEXAS%"),
USERS.DATE == "2021-08-08"
).group_by(USERS.DATE)
sq1 = query1.subquery()
sq2 = query2.subquery()
query3 = db.session.query(sq1, sq2).join(
sq2,
sq2.c.DATE_2 == sq1.c.DATE_1)
sq3 = query3.subquery()
query4 = db.session.query(
func.coalesce(
sq3.c.DATE_1, sq3.c.DATE_2),
sq3.c.QUESTIONS_CNT,
sq3.c.ANSWERS_CNT
)
results = query4.all()
