Question

下面的查詢仍然返回0的TC.ContractPartner列有人可以解釋爲什麼？

我用以防萬一 '0' 嘗試零爲文本

select distinct tc.ID 
, tc.[Contact Partner] 
, so.BusinessPartnerNumber 
, tc.[Actual Date From] 
, SO.ServiceOrder 
, SO.ServiceProduct 
, so.SOCreatedOn 

from AB.TradComplaints_Temp as TC 

left Join main.Tbl_ServiceOrder as SO on SO.BusinessPartnerNumber = tc.[Contact Partner] 

where tc.[Contact Partner] is not null 
and tc.[Actual Date From] > so.SOCreatedOn 
and so.SOCreatedOn > (tc.[Actual Date From]-90) 
and so.ServiceOrder is not null 

or tc.[Contact Partner] <> 0 
and tc.[Actual Date From] > so.SOCreatedOn 
and so.SOCreatedOn > (tc.[Actual Date From]-90) 
and so.ServiceOrder is not null 
order by tc.ID 

Answer 1

變化or到and：

and so.ServiceOrder is not null 
and tc.[Contact Partner] <> 0 

Answer 2

如果你想要得到的時候

so.ServiceOrder is not null or tc.[Contact Partner] <> 0  

然後將這些論文分組在文件夾中

select distinct tc.ID 
, tc.[Contact Partner] 
, so.BusinessPartnerNumber 
, tc.[Actual Date From] 
, SO.ServiceOrder 
, SO.ServiceProduct 
, so.SOCreatedOn 

from AB.TradComplaints_Temp as TC 

left Join main.Tbl_ServiceOrder as SO on SO.BusinessPartnerNumber = tc.[Contact Partner] 

where tc.[Contact Partner] is not null 
and tc.[Actual Date From] > so.SOCreatedOn 
and so.SOCreatedOn > (tc.[Actual Date From]-90) 
and (so.ServiceOrder is not null 

or RTRIM(LTRIM(tc.[Contact Partner])) <> '0') 
and tc.[Actual Date From] > so.SOCreatedOn 
and so.SOCreatedOn > (tc.[Actual Date From]-90) 
and so.ServiceOrder is not null 
order by tc.ID
