Question

How I should write my sql query in android that special characters work correct. For example when I filter String with like which has % symbol, it doesn’t work correct.

Answer 1

For LIKE, you choose in the query what to escape them with;

SELECT * FROM Olle WHERE name LIKE 'Many ^% have fallen' ESCAPE '^';

…will only match the actual character % since it’s been escaped with the ^ that is give in the ESCAPE clause.
