OPENQUERY With Quotes In The Query String

Hello,

how can I use the following statement with OPENQERY syntax:

SELECT 'hello world' FROM mytable

Maybe I have to transform quite a few and complex SQL-statements to the OPENQUERY syntax. Obviously I have problems with single quotes

SELECT * FROM OPENQUERY(LINKEDSERVER, 'select 'hello world' from mytable')

quotename('hello world', '''') does not help because this will create 'hello world' instead of hello world (w/o quotes).

How can I transform my SQL-statements with quotes to Openquery syntax?

regards

arno
