Question

I have this as my query:

public Cursor getQuests(int level) {
    final String[] columns = new String[] {KEY_ID, "title", "minUC", "maxUC", "xp", "ep", "request", "loot", "level", "numHits", "numHitsReq"};
    return db.query(QUESTS, columns, "level<=\"" + level + "\"", null, null, null, KEY_ID + ", level");
}

So, I have entries up to level 10 in my database. This query works normally up to a point, while players level is less than 10 everything works as expected, however when player is level 11 or higher the query only returns rows where level = 1.

When I remove the escaped quotes around level it returns an empty cursor. Am I doing something wrong?

Answer 1

Your problem is most likely due to the fact the LEVEL column in the database is text/string. Then you are comparing it to another string:

"1" <= "11"
"10" <= "11"
"11" <= 11"

but

"2" > "11"

However if you are to compare the values, you’ll get the expected results

1 <= 11
2 <= 11
and so on
11 <= 11

Change the database column to INTEGER and remove the quotes around level in your query – and you’ll be fine.
