You just double the apostrophies that are part of the literal value:

update table set f1='some=''asdfsadf'' ' where id=1;

Hi ,You can use the  apostrophies like this...
 
create table temp1
([id] int,f1 varchar(30))

insert into temp1(Id,f1) values(1,'sum=''asdfsadf''')

select * from temp1

update temp1
set f1='sum=''asdfsadf''' where id=1

select * from temp1

if you any other problem..let me know..
