如何在PostgreSQL字符串的单引号后添加分号？

Question

单引号后，我无法在PostgreSQL中用分号创建字符串。 例如。我需要创建一个像这样的字符串：

Delhi is India's capital; It's a beautiful state

如何创建这样的字符串？

我尝试了以下操作：

select 'Delhi is India\'s capital; It\'s a beautiful state'

我遇到以下错误：

Invalid operation: unterminated quoted string at or near "'Delhi is India\'s capital" 
Position: 8;

Answer 1

在SQL中，不要用反斜杠转义单引号，而是将它们加倍。分号不需要转义。

所以您应该使用

SELECT 'Delhi is India''s capital; It''s a beautiful state';

Answer 2

尝试Dollar-Quoted String Constants

knayak=# select $$Delhi is India's capital; It's a beautiful state$$  as s;
                        s
--------------------------------------------------
 Delhi is India's capital; It's a beautiful state
(1 row)
