大于 0 时连接值

Question

如果值大于 0，我需要连接多个列中的值。

例子：

Video     1  
Internet  0  
Phone     3  
Security  0  
Basic     1  

所以最终值为1 Video|3 Phone|1 Basic|

有没有比编写代码更好的方法：

    Case When Video > 0 and Internet+Phone+Security+Basic < 0 Then Video + ' Video|' 
    When Video > 0 and Internet > 0 and Phone+Security+Basic < 0 Then Video + ' Video|' + Internet + ' Internet|' 
    When Video > 0 and Phone > 0 and Internet+Security+Basic < 0 Then Video + ' Video|' + Phone + ' Phone|'

以此类推，直到每个组合都被考虑在内。

Answer 1

select
  Case When Video > 0     Then Video +     ' Video|'     else '' end +
  Case When Internet  > 0 Then Internet  + ' Internet|'  else '' end +
  Case When Phone > 0     Then Phone +     ' Phone|'     else '' end +
  Case When Security > 0  Then Security +  ' Security|'  else '' end +
  Case When Basic > 0     Then Basic +     ' Basic|'     else '' end +
