从单行显示两行

Question

这是给定的表格：

我需要在不创建基于上表的临时表的情况下获取此数据：

我们无法使用临时表。我只需要用sql查询显示数据。

Answer 1

试试这个

SELECT company name,'No' as value, clicks  as data
from table1
union all
SELECT company,'Yes', (clicks - impression)
from table1
order by name,val

Answer 2

您可以使用UNION ALL取消对表格的删除：

SELECT
    company,
    'No' AS val,
    impression AS data
FROM tbl
UNION ALL
SELECT
    company,
    'Yes' AS val,
    clicks - impression AS data
FROM tbl
ORDER BY company, val

Answer 3

你需要UNION ALL

SELECT company,'No' val, impression as data from your_table
union all
SELECT company,'Yes' val, clicks-impression as data from your_table

Answer 4

select company as name, 'No' as val, impression as data
from tbl
union
select company as name, 'Yes' as val, clicks - impression as data
from tbl

Answer 5

SELECT COMPANY AS NAME, 'YES' AS VAL, (CLICKS-IMPRESSIONS) AS DATA
FROM ORIGINAL_TABLE
UNION
SELECT COMPANY AS NAME, 'NO' AS VAL, IMPRESSIONS AS DATA
FROM ORIGINAL_TABLE

如果你想要它们排序：试试这个：

SELECT A.NAME, A.VAL, A.DATA FROM
(SELECT COMPANY AS NAME, 'YES' AS VAL, (CLICKS-IMPRESSIONS) AS DATA
FROM OR_TABLE
UNION
SELECT COMPANY AS NAME, 'NO' AS VAL, IMPRESSIONS AS DATA
FROM OR_TABLE) A
ORDER BY A.NAME ASC;
