反转行和列SQLite

Question

我正在开发和iOS游戏，我想切换cols和行

例如，这里是统计表：

StatName (STRING) | StatValue (NUMBER)
--------------------------------------
NbJoker           |      12
--------------------------------------
NbPlayed          |      71
--------------------------------------
NbPause           |      87
--------------------------------------

我需要

NbJoker | NbPlayed | NbPause
----------------------------
12      |     71   | 87

这可能吗？ 谢谢！

我不懂SQL Lite。但是如果以下语法有效。

它与任何SQL中的Transpose相同。

SELECT SUM(T1) AS NBJOKER, SUM(T2) AS NBPLAYED, SUM(T3) AS NBPAUSE FROM (
SELECT STATVALUE AS T1,O AS T2,0 AS T3 FROM TABLE_X WHERE STATNAME='NBJOKER'
UNION ALL
SELECT 0, STATVALUE, 0 FROM TABLE_X WHERE STATNAME='NBLAYED'
UNION ALL
SELECT 0, 0, STATVALUE FROM TABLE_X WHERE STATNAME='NBPAUSE'
)
