以下は私が使用するコードです:
public Map<String, String> GetSelectedApplicationUrlList() {
Cursor c = myDataBase.rawQuery("SELECT reco_index_user_action_download_file ," +
" reco_index_content_code from tbl_reco_index_contents where reco_index_content_type =" +
" 'Application/Widget' and reco_index_user_action_downloaded=1 and reco_index_user_action_installed =1 ",
null);
Map<String, String> sel = Collections
.synchronizedMap(new LinkedHashMap<String, String>());
if (c != null) {
if (c.moveToFirst()) {
do {
System.out.println("Url is"+c.getString(0));
System.out.println("Code is"+c.getString(1));
String url = c.getString(c.getColumnIndex(c.getString(0)));
String code = c.getString(c.getColumnIndex(c.getString(1)));
sel.put(code, url);
} while (c.moveToNext());
}
}
c.close();
return sel;
}
から例外がスローされます:
System.out.println("Url is"+c.getString(0));
sqliteman から同じクエリを実行すると、常に正しい結果が得られます。
この問題を解決するための助けは大歓迎です
テーブル構造は次のとおりです。
CREATE TABLE tbl_reco_index_contents (
id integer PRIMARY KEY,
reco_index_content_code char(10),
reco_index_content_type char(30),
reco_index_user_action_downloaded smallint,
reco_index_user_action_download_file char(50),
reco_index_user_action_installed smallint
)
