沒有這樣的列例外的SQLite

-1

IM使用SQLite數據庫做一個應用程序，並且在此沒有這樣的列例外的SQLite

public Prof getProffromcompte(int login){ 
    Cursor c = bdd.query(TABLE_PROF, new String[] {COL_ID_PROF, COL_NOM_PROF, COL_LOGIN_PROF}, COL_LOGIN_PROF + " LIKE \"" + login +"\"", null, null, null, null); 
    return cursorToProf(c); 
}

一個異常即時通訊，這是個日誌：

我驗證在創建表的時候我有同樣的相同的列名：nom_prof

但表的創建是在SqliteHelper類的onCreate數據庫或onUpgrade數據庫？ – Santiago

您能否請卸載申請一次從設備和再次運行？如果您已經創建的數據庫，你已經添加比數據庫的新列將不能反映馬上就當前的表結構。所以卸載應用程序將創建與更新數據結構數據庫的新實例後。
