Answer 1

Use an 'escape' quote:
select * from users where name ='o''reilly';
SQL> create table t as select 'o''reilly' name from dual union select 'kyte' from dual;
Table created.
SQL> select * from t;
NAME
kyte
o'reilly
2 rows selected.
SQL> select * from t where name = 'o''reilly';
NAME
o'reilly
1 row selected.
