Union ALL sum results in one row and keep summed values - sql

Question

I am trying to build a query which gets sum of different kinds of replications per user. I want to show a unified result with rows with each replication and another row which sums them into an all per user. Here is the query:
SELECT replica_name,
user_id,
short_name,
number_of_replications,
firstReplication,
lastReplication
FROM (SELECT 'Initial' AS replica_name,
sc.user_id AS user_id,
u.short_name AS short_name,
Count(sc.user_id) AS number_of_replications,
Min(sc.connected_at) AS firstReplication,
Max(sc.connected_at) AS lastReplication
FROM phoenix.synchro_connections sc
JOIN phoenix.users u
ON u.user_id = sc.user_id
WHERE Lower(sc.synchro_type) = 'initial'
AND sc.size_in_bytes IS NOT NULL
GROUP BY sc.user_id,
u.short_name,
sc.synchro_type
UNION ALL
SELECT 'Delta' AS replica_name,
sc.user_id AS user_id,
u.short_name AS short_name,
Count(sc.user_id) AS number_of_replications,
Min(sc.connected_at) AS firstReplication,
Max(sc.connected_at) AS lastReplication
FROM phoenix.synchro_connections sc
JOIN phoenix.users u
ON u.user_id = sc.user_id
WHERE Lower(sc.synchro_type) = 'delta'
AND sc.size_in_bytes IS NOT NULL
GROUP BY sc.user_id,
u.short_name,
sc.synchro_type
UNION ALL
SELECT 'All' AS replica_name,
sc.user_id AS user_id,
u.short_name AS short_name,
Count(sc.user_id) AS number_of_replications,
Min(sc.connected_at) AS firstReplication,
Max(sc.connected_at) AS lastReplication
FROM phoenix.synchro_connections sc
JOIN phoenix.users u
ON u.user_id = sc.user_id
WHERE Lower(sc.synchro_type) <> 'upload'
AND sc.size_in_bytes IS NOT NULL
GROUP BY sc.user_id,
u.short_name,
sc.synchro_type) AS t
WHERE short_name = 'BY060955'
ORDER BY replica_name ASC,
number_of_replications DESC
this is the result:
replica_name user_id short_name number_of_replications firstReplication LastReplication
All 22472 BY060955 836 2022-11-14 06:26:05.2415463 2022-12-08 10:25:17.4282712
All 22472 BY060955 2 2022-11-14 06:25:08.2385837 2022-11-16 11:55:41.0263526
Delta 22472 BY060955 836 2022-11-14 06:26:05.2415463 2022-12-08 10:25:17.4282712
Initial 22472 BY060955 2 2022-11-14 06:25:08.2385837 2022-11-16 11:55:41.0263526
I want for 'All' to be a single row (836+2 = 838) but'Delta' and 'Initial' to stay as they are

Answer 1

From the last query, remove the grouping by sc.synchro_type:
SELECT 'All' AS replica_name,
sc.user_id AS user_id,
u.short_name AS short_name,
Count(sc.user_id) AS number_of_replications,
Min(sc.connected_at) AS firstReplication,
Max(sc.connected_at) AS lastReplication
FROM phoenix.synchro_connections sc
JOIN phoenix.users u
ON u.user_id = sc.user_id
WHERE Lower(sc.synchro_type) <> 'upload'
AND sc.size_in_bytes IS NOT NULL
GROUP BY sc.user_id,
u.short_name
You should be able to calculated the above in a better way reading the rows from the tables only one. Then you can use UNPIVOT if you need the results in the same way:
SELECT sc.user_id AS user_id,
--
SUM(IIF(Lower(sc.synchro_type) = 'initial', 1, 0)) AS initial_number_of_replications,
MIN(IIF(Lower(sc.synchro_type) = 'initial', sc.connected_at, NULL)) AS initial_firstReplication,
MAX(IIF(Lower(sc.synchro_type) = 'initial', sc.connected_at, NULL)) AS initial_lastReplication,
--
SUM(IIF(Lower(sc.synchro_type) = 'delta', 1, 0)) AS delta_number_of_replications,
MIN(IIF(Lower(sc.synchro_type) = 'delta', sc.connected_at, NULL)) AS delta_firstReplication,
MAX(IIF(Lower(sc.synchro_type) = 'delta', sc.connected_at, NULL)) AS delta_lastReplication,
--
SUM(IIF(Lower(sc.synchro_type) <> 'upload', 1, 0)) AS ALL_number_of_replications,
MIN(IIF(Lower(sc.synchro_type) <> 'upload', sc.connected_at, NULL)) AS ALL_firstReplication,
MAX(IIF(Lower(sc.synchro_type) <> 'upload', sc.connected_at, NULL)) AS ALL_lastReplication
FROM phoenix.synchro_connections sc
INNER JOIN phoenix.users u
ON u.user_id = sc.user_id
WHERE Lower(sc.synchro_type) <> 'upload'
AND sc.size_in_bytes IS NOT NULL
AND u.short_name = 'BY060955'
GROUP BY sc.user_id
