Here is my query. I need it to be formatted so that it can run in Access 2007.
SELECT DISTINCT(meters.meterNo), readings.momentaryIntCount,
readings.readingDate,
ServiceLocations.servLoc
FROM readings
inner join EndPoints on readings.endPointId = endpoints.endPointId
join Meters on endpoints.meterId = meters.meterId
join spus on endpoints.spuid = spus.spuid
join ServiceLocations on meters.serviceLocationId = ServiceLocations.serviceLocationId
left join firmware on endpoints.firmwareId = firmware.firmwareId
left join virtualgroupassoc v on EndPoints.endpointid = v.objectid
left join groups g on v.groupid = g.groupid and g.grouptypeid in (4, 24) and g.active = 1
WHERE readings.readingDate = '01-01-2015'
and firmware.version >= '18'
and quality = 0
and g.name is null
ORDER BY meterNo
Joining multiple tables in Access is a bit of a bother. You have to nest the joins.
For example if you want to do this in SQL:
SELECT
a.columna
, b.columnb
, c.columnc
FROM tablea AS a
LEFT JOIN tableb AS b
ON a.id = b.id
LEFT JOIN tablec AS c
ON a.id = c.id
You'll need to do this in Access:
SELECT
a.columna
, b.columnb
, c.columnc
FROM (
(tablea AS a)
LEFT JOIN tableb AS b ON a.id = b.id)
LEFT JOIN tablec AS c ON a.id = c.id
So for your query:
SELECT
DISTINCT(meters.meterNo)
, readings.momentaryIntCount
, readings.readingDate
, ServiceLocations.servLoc
FROM ((((((
(readings)
INNER JOIN EndPoints
ON readings.endPointId = EndPoints.endPointId)
JOIN Meters
ON EndPoints.meterId = Meters.meterId)
JOIN spus
ON EndPoints.spuid = spus.spuid)
JOIN ServiceLocations
ON meters.serviceLocationId = ServiceLocations.serviceLocationId)
LEFT JOIN firmware
ON EndPoints.firmwareId = firmware.firmwareId)
LEFT JOIN virtualgroupassoc v
ON EndPoints.endpointid = v.objectid)
LEFT JOIN groups g
ON v.groupid = g.groupid AND g.grouptypeid in (4, 24) AND g.active = 1
WHERE readings.readingDate = '01-01-2015'
and firmware.version >= '18'
and quality = 0
and g.name is null
ORDER BY meterNo
