Searching For Double Quote In Sql Server 2005

Hi ,

I'm using sql server 2005. In my 'Books' table some of the 'subject' column contains data's with single and double quote. example: Quantu"m phys'ics

i'm passing the subject as parameter and it have to display results if the corresponding subject name is in the table. Here is my code... i'm using dynamic query...

 alter procedure getbooks
@sub varchar(200)
as
begin
declare @sqlq nvarchar(2000)
set @sqlq='select subject from books where subjectname like '''+@sub+'%'''
exec sp_executesql @sqlq
end

 How can i search for words like this Quantu"m phys'ics in the above query? Any one who knows how to do this please send me the code..
