如何從SQLite的

-2

public Cursor getSen_List(long id_thsen) { 
    String strTmp = "select " 
        +SENS_TABLE+"."+KEY_SEN_ID+"," 
        +SENS_TABLE+"."+KEY_SEN_ID_TH_SEN+"," 
        +SENS_TABLE+"."+KEY_SEN_ID_LANG+"," 
        +SENS_TABLE+"."+KEY_SEN+"," 
        +SENS_TABLE+"."+KEY_SEN_READING+"," 
        +" from "+SENS_TABLE+ "," 
        +" where "+SENS_TABLE+"."+KEY_SEN_ID_TH_SEN + "=" +id_thsen+"," 
        +null+"," +null+"," +null+"," +null; 
        return db.rawQuery(strTmp,null);}

這個查詢數據，我得到例句列表但如果我想改變的方式來寫這樣的而不是如何從SQLite的

public Cursor getSen_List(long id_thsen) { 
    String strTmp = "select " 
        +SENS_TABLE+"."+KEY_SEN_ID+"," 
        +SENS_TABLE+"."+KEY_SEN_ID_TH_SEN+"," 
        +SENS_TABLE+"."+KEY_SEN_ID_LANG+"," 
        +SENS_TABLE+"."+KEY_SEN+"," 
        +SENS_TABLE+"."+KEY_SEN_READING+","      
        +" from "+SENS_TABLE+"," 
        +" where "+SENS_TABLE+"."+KEY_SEN_ID_TH_SEN + id_thsen+"," 
        +null+"," +null+"," +null+"," +null+","; 
        return db.rawQuery(strTmp,null);}

的方式有什麼不對？因爲它不工作

請幫助........

，這是我的logcat ........

那麼，我需要的是一個誰幫助我= =謝謝 – 2011-02-10 14:51:05

與那種態度，你不會得到太多...... – techiServices 2011-02-10 15:13:42

那麼，檢查什麼混亂產生 - 然後嘗試通過sqlite CLI（命令行界面，PC上的SQLite很好）來運行它。發現問題。 – 2011-02-10 15:52:32

您當前的查詢strTmp結果（測試值）：

「select tblname.key_1，tblname.key_2，tblname.key_3，tblname.key_4，tblname.key_5，from tblname，where tblname.key_24，null，null，null，null，」

所以使它成爲一個有效的SQLite的查詢，您應使用此代碼

String strTmp = "select " 
     +SENS_TABLE+"."+KEY_SEN_ID+"," 
     +SENS_TABLE+"."+KEY_SEN_ID_TH_SEN+"," 
     +SENS_TABLE+"."+KEY_SEN_ID_LANG+"," 
     +SENS_TABLE+"."+KEY_SEN+"," 
     +SENS_TABLE+"."+KEY_SEN_READING      
     +" from "+SENS_TABLE 
     +" where "+SENS_TABLE+"."+KEY_SEN_ID_TH_SEN + "=" + id_thsen;

導致：「選擇tblname.key_1，tblname.key_2，tblname.key_3，tblname.key_4，tblname。 key_5 from tblname where tblname.key_2 = 4「

+" from "+SENS_TABLE" 
+" where "+SENS_TABLE+"."+KEY_SEN_ID_TH_SEN + "=" +id_thsen+","

嘗試。

編輯：

+" from "+SENS_TABLE+","不應該有最後的+"," 和你缺少此字符串的+ "="和+id_thsen+","之間KEY_SEN_ID_TH_SEN
