如何在SQL Server中連接unicode字符串？

Question

我有一個獨特的情況，我需要連接基於2組的行。另一個技巧是串聯必須能夠顯示項目符號並添加換行符。這是我的業務要求。我還應該添加最終目標將是Excel。我已經使用包含項目符號和換行符的數據測試了使用SSIS導出到Excel，並且此部分工作正常。

如何去從：

pk orgnl_pk type text 
1 1   one • Line One 
2 1   one • Line Two 
3 1   one • Line Three 
4 1   two • Line One 
7 3   one • Line One 
8 3   two • Line One 
9 3   two • Line Two 

要：

orgnl_pk type text 
1   one  • Line One 
        • Line Two 
        • Line Three 
1   two  • Line One 
3   one  • Line One 
3   two  • Line One 
        • Line Two 

Answer 1

由於Lamak指出，這是最好的留到表現層，但如果你必須這樣做在SQL現在。 ..然後這使用stuff() with select ... for xml path ('') method of string concatenation。

select 
    orgnl_pk 
    , [type] 
    , [text]=stuff(
     (
     select char(10) +i.[text] 
      from t as i 
      where i.orgnl_pk = t.orgnl_pk 
      and i.[type]=t.[type] 
      order by i.pk 
     for xml path (''), type).value('.','nvarchar(max)') 
     ,1,0,'') 
from t 
group by orgnl_pk, [type]

更新字符（0x0007）：

select 
    orgnl_pk 
    , [type] 
    , [text]=replace(stuff(
     (
     select char(10)+replace(i.[text],nchar(0x0007),'$BEL$') 
      from t as i 
      where i.orgnl_pk = t.orgnl_pk 
      and i.[type]=t.[type] 
      order by i.pk 
     for xml path (''), type).value('.','nvarchar(max)') 
     ,1,1,''),'$BEL$',nchar(0x0007)) 
from t 
group by orgnl_pk, [type]
