Replace A Single Apostrophe With Double - In Sql

I have the following:

---------------

That is only part of a large query that writs a SQL Query to a column in a Database. That Query (in the column) is just ran normally so I don't need to compile it each time I want to run it.

THe problem I have is @FieldName might be: ryan's field.

That apostrophe is killing me because the SQL keeps it as ryan's field, not ryan''s field(note the 2 apostrophes). I cannot do: REPLACE(@FieldName, ''', '''') because it's not closing the apostrophes. Is there an escape character that I can use to say only one: ' ?

I tried:

DECLARE @t VARCHAR(500)
SET @t = (SELECT [Name] FROM [Form].[Fields] WHERE FieldID = 1)
print @t -- @t will print: Ryan's Field
PRINT QUOTENAME('' + @t + '', '''')

but that gives me: 'Ryan''s Field'

Any help would rock. If I make any changes to the way this field is input into the DataBase, I know I will need to do a lot of re-work in many spots. WHich is why i'm trying to solve this on the SQL side.
