在单个记录上返回多行

Question

我需要检索此结果：

ROW1.id | ROW2.id | ROW3.id | ROW4.id
   1    |    2    |    3    |    4

从此结果开始select * from Table：

id | value
1  | sample1
2  | sample2
3  | sample3
4  | sample4

任何想法？

感谢， 安德烈

Answer 1

尝试查看SQL的pivot

Answer 2

你可以这样做：

select 
 (select id from table X where X.something = 123) as row1Id,
 (select id from table X where X.something = 456) as row2Id,
 (select id from table X where X.something = 789) as row3Id
