在这种情况下使用 SQL PIVOT？

Question

The scenario is:

Table name is = dw.tm_usage_monthly
Columns are; account ID = unique ID by customer
usage_month = is usage month as 201901, 201902
uom = Mbps or Nodes
usage = usage by month by account_id and uom

The database has data like below;

Is it possible to do in SQL? I'm using SQL workbench.

Answer 1

Just use conditional aggregation:

select account_id,
       sum(case when month = 201901 and oum = 'Nodes' then usage end) as nodes_201901,
       . . .
       sum(case when month = 201901 and oum = 'Mpbs' then usage end) as mpbs_201901,
       . . .
from t
group by account_id;
