如何逃避Presto的单一报价？

Question

如何在Presto中转义'（单引号）？

这是我尝试使用它的地方

select count(*) as count from uploads where title not in ('Driver's License')

我已尝试过常见的逃避：'Driver\'s License'，"Driver's License"，E'Driver\'s License'但似乎没有任何效果。 Presto的文档很模糊。有人知道吗？

Answer 1

a_horse_with_no_name提供的答案是使用其他'。

'Driver''s License'

Answer 2

用两个引号代替单引号，你需要转义：

select count(*) as count 
from uploads
where title not in ('Driver''s License')

Answer 3

在需要单引号的任何地方使用CHR(39)字符函数。与concat函数或双管道||一起使用：

select count(*) as count 
from uploads
where title not in (concat('Driver', CHR(39), 's License'))

或

select count(*) as count 
from uploads
where title not in ('Driver' || CHR(39) || 's License')
