Question

我需要在此报告中添加最大交易日期，以便我可以查看不属于查询参数的患者的最近交易日期。该报告将进入水晶报告，我计划将每个患者的最后一个服务日期日期放在组头中。以下代码是为了获得每位患者的最长日期。我需要插入结果，因此需要接受以下报告的患者并给出他们的最大日期。无论输入什么日期。先感谢您。 SQL Server 2005.

select 
patient_id, 
Max(proc_chron) 

from patient_clin_tran pct
group by patient_id

交易守则

select patient_id,

(select p.case_status from patient p where p.patient_id = btb.patient_id and p.episode_id = (select max(episode_id) from patient p2 where p2.patient_id = p.patient_id)) as 'Status',
(select p.lname +', '+ p.fname from patient p where p.patient_id = btb.patient_id and p.episode_id = (select max(episode_id) from patient p2 where p2.patient_id = p.patient_id)) AS 'client',
Coverage_plan_id, 
(select proc_code from billing_transaction bt where bt.clinical_transaction_no = btb.clinical_transaction_no and bt.coverage_plan_id=btb.coverage_plan_id and bt.coverage_plan_id = btb.coverage_plan_id) as 'Procedure',
proc_chron, 
(select billing_amt from billing_transaction bt where bt.clinical_transaction_no = btb.clinical_transaction_no and bt.coverage_plan_id = btb.coverage_plan_id) as 'Billing Amount',
balance_amount,
(select max (accounting_date) from  billing_ledger bl where bl.clinical_transaction_no = btb.clinical_transaction_no and subtype = 'pa' and bl.coverage_plan_id = 'standard') as 'Last Payment on Trans',
(select max (instrument_date) from payment p where p.patient_id = btb.patient_id and  p.coverage_plan_id = 'standard') as 'Last Payment on Acct',
(select sum(balance_amount) from billing_transaction_balance btb2 where btb2.patient_id=btb.patient_id and btb2.coverage_plan_id=btb.coverage_plan_id and proc_chron <= CONVERT(CHAR(6), DATEADD(year, -1, DATEDIFF(day, 0,GETDATE())), 112) + '01' and btb2.coverage_plan_id   in('standard')) AS 'Balance'

from billing_transaction_balance btb

where proc_chron <= CONVERT(CHAR(6), DATEADD(year, -1, DATEDIFF(day, 0, GETDATE())), 112) + '01' and coverage_plan_id   in('standard') 

group by patient_id, proc_chron, coverage_plan_id, balance_amount, clinical_transaction_no

在您的交易代码中，您需要将所有未汇总的选择列添加到分组依据。我在Select语句中计算了8个非聚合列，因此您必须在Group By中包含所有8个。

将最大日期子查询添加到group by子句
