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.

这应该是可行的:使用反斜杠和双引号

"UPDATE my_table SET row =\"hi, my name's tim.\";

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。

通过将单引号加倍来转义，就像您在示例中展示的那样。下面的SQL说明了这个功能。我在SQL Server 2008上进行了测试:

DECLARE @my_table TABLE (
    [value] VARCHAR(200)
)

INSERT INTO @my_table VALUES ('hi, my name''s tim.')

SELECT * FROM @my_table

结果

value
==================
hi, my name's tim.

如果用另一个单引号转义单引号对您不起作用(就像我最近的一个REPLACE()查询一样)，您可以在查询之前使用SET QUOTED_IDENTIFIER OFF，然后在查询之后使用SET QUOTED_IDENTIFIER ON。

例如

SET QUOTED_IDENTIFIER OFF;

UPDATE TABLE SET NAME = REPLACE(NAME, "'S", "S");

SET QUOTED_IDENTIFIER ON;
-- set OFF then ON again
