How to search data from oracle database which contains single quote

Question

my_table contains three columns: name, address1, and address2.

I want to find all records which contains single quotes. How can I do this?

Answer 1

You have to escape the single quotes in the expressions by doubling them, e.g.:

select * from my_table
where name like '%''%'
or address1 like '%''%'
or address2 like '%''%';

Answer 2

... where name || address1 || address2 like '%''%';
