erhalten die Ergebnisse der beiden Abfragen in einer Abfrage

Question

Ich habe zwei Anfragen

QUERY 1

SELECT SUM(amount) as m1 , bank 
from test t1 
group by bank 

QUERY 2

SELECT SUM(amount21) as m , bank 
from test2 t1 
group by bank 

Wie die Ergebnisse der beiden Abfragen in einer Abfrage zu bekommen?

m | m1 | bank 

Answer 1

Ich nehme an, Sie möchten eine FULL OUTER JOIN.

select q1.m1, q2.m, coalesce(q1.bank, q2.bank) 
from 
(
    SELECT SUM(amount) as m1 , bank 
    from test t1 
    group by bank 
) q1 
FULL OUTER JOIN 
(
    SELECT SUM(amount21) as m , bank 
    from test2 t1 
    group by bank 
) q2 on q1.bank = q2.bank 

Answer 2

Füllen Sie, was Sie brauchen:

SELECT x.a, y.b 
FROM (SELECT * from a) as x, (SELECT * FROM b) as y 
GROUP BY bank
