如何在sql命令中使用單引號？

可能重複：
How do I escape a single quote in sqlserver?如何在sql命令中使用單引號？

我下面一個腳本的數據庫從this link放下一切。我在這條線上執行時會出錯。

SET @statement = ' 
IF(@type = 'F') or (@type = 'C') or (@type = 'D') or (@type='F') or (@type='K')

原因是因爲單引號。我想知道我該如何解決這個錯誤？

如果你想使用單引號一份聲明中，與其他單引號，例如逃吧

，

SET @statement = 'world''s view'; 
SET @statement2 = 'world''s view';

從你上面的例子

SET @statement = ' 
       IF(@type = ''F'') or (@type = ''C'') or 
        (@type = ''D'') or (@type=''F'') or 
        (@type=''K'')' 

-- the strings are all red.

單引號用於在SQL中表示字符串文字。如果您需要明確地插入一個單引號，你應該使用雙單引號（「」）

它應該是這樣的：

SET @statement = 'IF(@type = ''F'') or (@type = ''C'') or (@type = ''D'') or (@type=''F'') or (@type=''K'')'
