Question

following is my code to call the database to find the substring “ello”.

String queryString = "from ContentItem where singerName = '%"+searchString+"%' OR  songName = '%"+searchString+"%'";
System.out.println(queryString);
Query query = session.createQuery(queryString);
return query.list();  

the string output is

from ContentItem where singerName = '%ello%' OR songName = '%ello%'

it says Unexpected Token for %. How to make this possible to search substring inside those columns?

I’m working Hibernate inside Tapestry.

Answer 1

the equals (=) operator does not work with wildcards. You need to use like (or ilike).

eg

SELECT * FROM table WHERE column like '%abc%';
