如何将SQL关键字不用作关键字

我试图转换一个数据表——我希望行变成列，列变成行（就像一个完整的轴）。我正在使用的方法从这样做

如果有什么不同的话，我正在使用PHPMyAdmin在Raspberry Pi上运行自己的SQL server

表（截断）如下所示：

Personality|Abby|Aidan|Brandon|Bobby
Agreeabl...|93  |65   |74     |68
Compassion |95  |65   |96     |96
Politeness |81  |9    |21     |12
Conscient..|45  |13   |99     |28

我试图将其转换为：

Coach  |Agreeableness|Compassion|Politeness|Conscientiousness
Abby   |93           |95        |81        |45
Aidan  |65           |96        |9         |13 
Brandon|74           |96        |21        |99
Bobby  |68           |96        |12        |28

我的问题是：

SELECT Coach,
        MAX(CASE WHEN Personality = 'Agreeableness' THEN value END) `Agreeableness`,
        MAX(CASE WHEN Personality = 'Compassion' THEN value END) `Compassion`,
        MAX(CASE WHEN Personality = 'Politeness' THEN value END) `Politeness`,
        MAX(CASE WHEN Personality = 'Conscientiousness' THEN value END) `Conscientiousness`,
        MAX(CASE WHEN Personality = 'Industriousness' THEN value END) `Industriousness`,
        MAX(CASE WHEN Personality = 'Orderliness' THEN value END) `Orderliness`,
        MAX(CASE WHEN Personality = 'Extraversion' THEN value END) `Extraversion`,
        MAX(CASE WHEN Personality = 'Enthusiasm' THEN value END) `Enthusiasm`,
        MAX(CASE WHEN Personality = 'Assertiveness' THEN value END) `Assertiveness`,
        MAX(CASE WHEN Personality = 'Neuroticism' THEN value END) `Neuroticism`,
        MAX(CASE WHEN Personality = 'Withdrawal' THEN value END) `Withdrawal`,
        MAX(CASE WHEN Personality = 'Volatility' THEN value END) `Volatility`,
        MAX(CASE WHEN Personality = 'Openness' THEN value END) `Openness`,
        MAX(CASE WHEN Personality = 'Intellect' THEN value END) `Intellect`,
        MAX(CASE WHEN Personality = 'Openness (Aspect)' THEN value END) `Openness (Aspect)`
  FROM 
(
  SELECT Personality, Coach,
         CASE Coach

在部分代码中，我需要在“Grant”之后再Grant时编写，但第二个不带引号的Grant会变成一个关键字，并干扰我的代码。当我把格兰特放在单引号中时，它会在我写“c”的地方进一步抛出一个语法错误，但我怀疑我的小欺骗可能与此有关。我该怎么办？

你似乎在暗示，

Grant

是一个列名——这是个糟糕的选择，但你还是坚持了。转义名称的标准方法是使用双引号：

WHEN 'Grant' THEN "Grant"

某些数据库使用反勾号或方括号：

WHEN 'Grant' THEN `Grant`
WHEN 'Grant' THEN [Grant]

请将您的查询添加到questionSample数据中，所需的结果也会有所帮助。并用正在使用的数据库进行标记。表的方向错误。你应该有同意的专栏。。。同情心等，也是教练。并为每个coach存储一行，其中包含coach名称和其他值。我不确定它是否有效，但我正在使用MariaDB，并且语法错误仍然存在。我想我会写一个关于这个问题的后续q。第一个或第二个选项应该有效。
