Question

我收到错误：

Msg 512，Level 16，State 1，Line 1

运行我的查询时。我知道冲突的位置：只是试图确定如何隔离相关列以解决错误。

特定列称为PARAMETER_SET.TEMPLATE_VERSION。它有两个值。以下查询中的数据跨两个template_version值复制，这导致512消息（即，商家，标题3，FID，UID，MID都被复制）。

注意：在创建第二个template_version值并填充数据库之前，我能够成功运行下面的查询。

我的目标是查询输出只包含一个template_version的数据，这应解决我的512问题。

select 
    t.signature, rp.SIGNATURE as 'estate', 
    tp2.SIGNATURE as 'sub-estate1', 
    tp1.SIGNATURE as 'sub-estate2',  
    (select VALUE 
     from PARAMETER_VALUES pv
     join PARAMETER_SET ps on ps.DATASET_ID = pv.DATASET_ID 
     where FIELD_ID = 'Merchant.1.RcptHdrLn1' 
       and ps.TERMINAL_ID = t.TERMINAL_ID) as 'Merchant1|RcptHdrLn1',
    (select VALUE 
     from PARAMETER_VALUES pv
     join PARAMETER_SET ps on ps.DATASET_ID = pv.DATASET_ID 
     where FIELD_ID = 'Merchant.1.RcptHdrLn2' 
       and ps.TERMINAL_ID = t.TERMINAL_ID) as 'Merchant1|RcptHdrLn2',
    (select VALUE 
     from PARAMETER_VALUES pv
     join PARAMETER_SET ps on ps.DATASET_ID = pv.DATASET_ID 
     where FIELD_ID = 'Merchant.1.Host0|Acq0|Mid' 
       and ps.TERMINAL_ID = t.TERMINAL_ID) as 'Merchant1|Host0|Acq0|Mid',
    (select VALUE 
     from PARAMETER_VALUES pv
     join PARAMETER_SET ps on ps.DATASET_ID = pv.DATASET_ID 
     where FIELD_ID = 'Merchant.1.Fid' and ps.TERMINAL_ID = t.TERMINAL_ID) as 'Merchant1|Fid',
    (select VALUE 
     from PARAMETER_VALUES pv
     join PARAMETER_SET ps on ps.DATASET_ID = pv.DATASET_ID 
     where FIELD_ID = 'Merchant.1.Uid' and ps.TERMINAL_ID = t.TERMINAL_ID) as 'Merchant1|Uid',
    (select VALUE 
     from PARAMETER_VALUES pv
     join PARAMETER_SET ps on ps.DATASET_ID = pv.DATASET_ID 
     where FIELD_ID = 'Header3' and ps.TERMINAL_ID = t.TERMINAL_ID) as 'Header3'
from 
    terminal t 
join 
    terminal tp1 on t.PARENT_ID = tp1.TERMINAL_ID 
join 
    terminal tp2 on tp1.PARENT_ID = tp2.TERMINAL_ID 
join
    terminal rp on tp2.PARENT_ID = rp.TERMINAL_ID 
order by 
    estate, [sub-estate1], [sub-estate2]
