sql - 在 SQL 中创建 CSV 字符串

Question

<分区>

Answer 1

这是聚合字符串连接的变体——但没有聚合。

我会这样写:

select t.name, t.value1,
       stuff((select ',' + cast(t2.value2 as varchar(8000))
              from table t2
              where t2.name = t.name
              order by t2.value1
              for xml path ('')
             ), 1, 1, '') as value2_csv
from table t;
