Answer 1

变化

'SELECT'113'

到

'SELECT 113

或

'SELECT“113”

希望它有所帮助。

Answer 2

当你编写'SELECT '113'||时，你正在终止包含SELECT语句的dblink（）调用的第二个参数，然后你启动一个113的数字文字。

'SELECT 113有效，因为它会选择一个数字而不是字符文字。 然后，||运算符将以静默方式将其转换回字符值。

在字符文字中嵌入单引号的正确方法是编写两个单引号：

, 'SELECT ''113''||substring(... '

Answer 3

使用E或美元报价。

...
FROM dblink('dbname=perpus2 port=5432 user=dbdev password=develop',
          $my_dblink_arg$SELECT '113' ||
...
      FROM kuesioner 
         ORDER BY bb, cc, dd$my_dblink_arg$) AS kuesioner
...
