How Can I write in my code to exclude accounts that have had a payment posted w/in last 45 days? - sql

Question

I'm working in SQL Server Mgmt Studio and I'm trying to identify accounts that have not had a payment posted since the last 45 days. I've tried declaring a min and max date with getdate being less than 45 days, but that didnt work. I've also tried stating "where last payment !> getdate() -45".... but this did not give me the results I was looking for. what I need the query to do is only identify accounts that truly have not had a payment post in the last 45 days. but I'm not sure how to state this in my where clause. Here's my query
DECLARE #minDate datetime;
DECLARE #maxDate datetime;
SET #minDate = GETDATE();
SET #maxDate = GETDATE() - 45;
SELECT DISTINCT
a.id,
a.FacilityCode AS [Facility],
a.accountUnit,
a.accountNum AS [Account Number],
a.amountBalance AS [Balance],
a.accountstatus AS [Status],
CONVERT(date, a.accountStatusDate) AS StatusDate,
pmtEntryDate AS [Pmt Entry Date],
v.LastLinkARpmtDate AS [Last Pmt Date],
CONVERT(date, a.accountnextactdate) AS NextActionDate,
CONVERT(date, a.rpcDate) AS RightpartyContactDate,
a.flag AS accountFlag,
pay.flag AS pmtFlag,
a.accounttype
FROM dbo.tbAccount a
JOIN dbo.tbpmtinfo pay ON a.id = pay.id
JOIN dbo.vLastPmtDate v ON v.id = a.id
FULL JOIN (SELECT id,
MAX(deDate) AS MFSLoadDate
FROM dbo.tbDataEvents (NOLOCK)
WHERE deNewVal = 'MFS'
GROUP BY id) m ON m.id = a.id
WHERE pay.flag IN ('D')
AND a.amountBalance > 0
AND a.FacilityCode IN ('PHKY', 'QANM', 'QAOH', 'QBCA', 'QBIL', 'QBTX', 'QCIL', 'QDAL', 'QEWY', 'QFAR', 'QFGA',
'QGIL', 'QHAR', 'QHIL', 'QHTN', 'QLAL', 'QLPA', 'QMIL', 'QMNC', 'QMNM', 'QMNV', 'QMOR',
'QMTN', 'QMTX', 'QMUT', 'QRIL', 'QRKY', 'QSPA', 'QTGA', 'QTKY', 'QUIL', 'QVIL', 'QWIL', 'LHFL')
AND a.amountBalance >= '1000'
AND a.accountStatus IN ('PA', 'PP', 'BPA')
AND a.flag = 'A'
AND a.accountType IN ('Resid', 'Slfpy')
--and LastLinkARpmtDate !> Getdate() -45 and accountNum = '40728597'
AND LastLinkARpmtDate BETWEEN #minDate AND #maxDate;

Answer 1

I would use a WHERE NOT EXISTS clause to eliminate recent activity:
SELECT DISTINCT a.id
,a.FacilityCode [Facility]
,a.accountUnit
,a.accountNum [Account Number]
,a.amountBalance [Balance]
,a.accountstatus [Status]
,convert(DATE, a.accountStatusDate) StatusDate
,pmtEntryDate [Pmt Entry Date]
,v.LastLinkARpmtDate [Last Pmt Date]
,convert(DATE, a.accountnextactdate) NextActionDate
,convert(DATE, a.rpcDate) RightpartyContactDate
,a.flag AS accountFlag
,pay.flag AS pmtFlag
,a.accounttype
FROM dbo.tbAccount AS a
JOIN dbo.tbpmtinfo AS pay ON a.id = pay.id
JOIN dbo.vLastPmtDate AS v ON v.id = a.id
FULL JOIN (
SELECT id
,Max(deDate) AS MFSLoadDate
FROM dbo.tbDataEvents(NOLOCK)
WHERE deNewVal = 'MFS'
GROUP BY id
) m ON m.id = a.id
WHERE pay.flag IN ('D')
AND a.amountBalance > 0
AND a.FacilityCode IN (
'PHKY'
,'QANM'
,'QAOH'
,'QBCA'
,'QBIL'
,'QBTX'
,'QCIL'
,'QDAL'
,'QEWY'
,'QFAR'
,'QFGA'
,'QGIL'
,'QHAR'
,'QHIL'
,'QHTN'
,'QLAL'
,'QLPA'
,'QMIL'
,'QMNC'
,'QMNM'
,'QMNV'
,'QMOR'
,'QMTN'
,'QMTX'
,'QMUT'
,'QRIL'
,'QRKY'
,'QSPA'
,'QTGA'
,'QTKY'
,'QUIL'
,'QVIL'
,'QWIL'
,'LHFL'
)
AND a.amountBalance >= '1000'
AND a.accountStatus IN (
'PA'
,'PP'
,'BPA'
)
AND a.flag = 'A'
AND a.accountType IN (
'Resid'
,'Slfpy'
)
AND NOT EXISTS (
SELECT NULL
FROM vLastPmtDate
WHERE v.id = a.id
AND CAST(v.LastLinkARpmtDate AS DATE) > CAST(dateadd(day, - 45, getdate() AS DATE))
)
AND accountNum = '40728597'
AND LastLinkARpmtDate BETWEEN #minDate
AND #maxDate;

Answer 2

The function dateadd() is what you need:
DATEADD (datepart , number , date)
Set #maxDate = DATEADD(DAY, -45, GETDATE());
