Android的SQLite不查询列1和2和column2之间的人？

Question

I have my database that was working with

db.rawQuery("SELECT* FROM "+TABLE+" WHERE "+COLUMN1+" BETWEEN ('1') AND ('2')", null);

this works fine but when i switch it to

db.rawQuery("SELECT* FROM "+TABLE+" WHERE "+COLUMN1+" BETWEEN ('1') AND ('2') "+
"AND "+COLUMN2+" LIKE ('PERSONSNAME')", null);

my database does not query my selection. but when i change it to

db.rawQuery("SELECT* FROM "+TABLE+" WHERE "+COLUMN1+" LIKE ('1')  AND "+
COLUMN2+ " LIKE ('PERSONNAME')", null);

it works with that. can some one tell me what my problem is?

Answer 1

I figured out a solution. The method

db.rawQuery("SELECT* FROM "+TABLE+" WHERE "+COLUMN1+" BETWEEN ('1') AND ('2') "+
"AND "+COLUMN2+" LIKE ('PERSONSNAME')", null);

Did not work. but as soon as I changed the BETWEEN statement to <= and >= the query gave me the result I was looking for

db.rawQuery("SELECT* FROM "+TABLE+" WHERE "+COLUMN1+" <= ('1') AND "+COLUMN1+" >= ('2') "+
"AND "+COLUMN2+" LIKE ('PERSONSNAME')", null);
