-- A plate can map to more than one tracksolid.devices row (a vehicle re-fitted
|

|
|
-- with a new tracker keeps the same number plate), so the migration-01 plain
|
||
|
|
-- LEFT JOIN produced multiple rows per fill and double-counted litres / spend
|
||
|
|
-- (v_fuel_fills had ~3345 rows for ~1888 live records). Replace the join with a
|
||
|
|
-- LATERAL ... LIMIT 1 that picks exactly one device per fill (prefer enabled,
|
||
|
|
-- most-recently-updated), so each fill yields a single row. Columns unchanged,
|
||
|
|
-- so dependent reporting.v_fuel_efficiency stays valid. Idempotent.
