将两个sql列合并为一列

Question

我有两列的表,它们都包含整数值,如下所示:

DocumentUpId    RelatedDocId
31608768        31624333
31608768        31624334
31618133        31618117

我试图将它们合并为一个列,如下所示:

DocumentUpId    
31608768        
31608768        
31618133    
31624333
31624334
31624334

我试过这个:

select rel_CTE.DocumentUpId + rel_CTE.DocumentDownId as 'RelatedDocId' 
into #temprelations 
from RelationsCTE rel_CTE

但它让我连接了值(在这种情况下总和),所以它可能吗？

Answer 1

UNION ALL

select rel_CTE.DocumentUpId  as 'RelatedDocId'  from RelationsCTE
union all
select rel_CTE.DocumentDownId from RelationsCTE
