双倍的引用本应有效，但奇怪的是它没有对你起作用;但是，另一种方法是在字符串周围使用双引号字符，而不是单引号字符。也就是说,

插入my_table值("hi, my name's tim.");

只要在要插入的任何东西之前插入一个'。它将像sqlServer中的转义字符

例子: 当你有场作为，我很好。 你可以: UPDATE my_table SET row ='I' m fine.';

如何:

insert into my_table values('hi, my name' + char(39) + 's tim.')

双引号选项帮助我

SET QUOTED_IDENTIFIER OFF;
insert into my_table values("hi, my name's tim.");
SET QUOTED_IDENTIFIER ON;

Also another thing to be careful of is whether or not it is really stored as a classic ASCII ' (ASCII 27) or Unicode 2019 (which looks similar, but not the same). This isn't a big deal on inserts, but it can mean the world on selects and updates. If it's the unicode value then escaping the ' in a WHERE clause (e.g where blah = 'Workers''s Comp') will return like the value you are searching for isn't there if the ' in "Worker's Comp" is actually the unicode value.If your client application supports free-key, as well as copy and paste based input, it could be Unicode in some rows, and ASCII in others! A simple way to confirm this is by doing some kind of open ended query that will bring back the value you are searching for, and then copy and paste that into notepad++ or some other unicode supporting editor. The differing appearance between the ascii value and the unicode one should be obvious to the eyes, but if you lean towards the anal, it will show up as 27 (ascii) or 92 (unicode) in a hex editor.

下面的语法将只转义一个引号:

SELECT ''''

结果将是一个单引号。对于创建动态SQL:)可能非常有帮助。
