Escape Character in SQL

问题:

Please forgive me as I am a bit of an sql noob. I am trying to do an insert using the following but am having a problem with the apostrophes. I have a lots of records to insert but many have the same problem. Is there a way of escaping them?

INSERT INTO  [dbo].[tb_Chefs] ([ChefHotelID], [HotelID], [ChefID],         [Position],  [GroupID])   VALUES(N'b809a86e-f7f2-45b2-a240-0049f51509d7' ,N'14481', N'624',       N'Chef d'atelier', N'331') GO 

Any help much appreciated.

回答1:

'Chef d'atelier' becomes 'Chef d''atelier'

Just double them up

If a character string enclosed in single quotation marks contains an embedded quotation mark, represent the embedded single quotation mark with two single quotation marks.

回答2:

You can also you the ESCAPE clause. This allows you to define your own escape character.

回答3:

Use something like this instead

INSERT INTO [dbo].[tb_Chefs] ([ChefHotelID], [HotelID], [ChefID], [Position], [GroupID])
VALUES("N'b809a86e-f7f2-45b2-a240-0049f51509d7'" ,"N'14481'", "N'624'", "N'Chef d'atelier', N'331'")

OR you could store the values you want to insert in a variable first and then use the variable in the SQL statement instead of the raw value.
