Search multiple columns in sqlite SELECT FROM

Question

I use this code to search for Column A. What modification should I make if I want to search Column A and Column B simultaneously?

String sql = \"SELECT * FROM \"         


        

Answer 1

Make two differrent query. And combine results by union keyword.

select * from TABLE_NAME where columnA like ? order by columnA limit 100
union
select * from TABLE_NAME where columnB like ? order by columnA limit 100
