Android：SQLite函数不返回有效数据

Question

好吧......我很难过！我写了下面的代码大约13 - 2月 - 2013年和它前几天的工作完美截至：

/** 
* Get a count of all resources in the selected Alliance 
* 
* @param db The EWTraker db 
* @param Sector the Sector to be accessed 
* @param Alliance the Alliance to be accessed */ 
public long[] getCountAllc(SQLiteDatabase db, String Sector, String Alliance){ 
    if (BuildConfig.DEBUG) { 
     Log.i(Constants.TAG_DBHELPER, "getCountAllc(): Sector: "+Sector); 
     Log.i(Constants.TAG_DBHELPER, "getCountAllc(): Alliance: "+Alliance); 
    } 
    long[] mTblCountArray = new long[6]; 
    String[] s = new String[2]; 
    s[0] = Sector; 
    s[1] = Alliance; 
    try{ 
     mTblCountArray[0] = DatabaseUtils.queryNumEntries(db,"TPLYS","FSECTR=? AND FANAME=?",s); 
     mTblCountArray[1] = DatabaseUtils.queryNumEntries(db,"TBASE","FSECTR=? AND FANAME=?",s); 
     mTblCountArray[2] = DatabaseUtils.queryNumEntries(db,"TBLDG","FSECTR=? AND FANAME=?",s); 
     mTblCountArray[3] = DatabaseUtils.queryNumEntries(db,"TTRPS","FSECTR=? AND FANAME=?",s); 
     mTblCountArray[4] = DatabaseUtils.queryNumEntries(db,"TINVY","FSECTR=? AND FANAME=?",s); 
     mTblCountArray[5] = DatabaseUtils.queryNumEntries(db,"TMSNS","FSECTR=? AND FANAME=?",s); 
     if (BuildConfig.DEBUG) { 
      Log.i(Constants.TAG_DBHELPER, "getCountAllc(): Alliance No. of Players: "+mTblCountArray[0]); 
      Log.i(Constants.TAG_DBHELPER, "getCountAllc(): Alliance No. of Bases: "+mTblCountArray[1]); 
      Log.i(Constants.TAG_DBHELPER, "getCountAllc(): Alliance No. of Buildings: "+mTblCountArray[2]); 
      Log.i(Constants.TAG_DBHELPER, "getCountAllc(): Alliance No. of Troup Rows: "+mTblCountArray[3]); 
      Log.i(Constants.TAG_DBHELPER, "getCountAllc(): Alliance No. of Items: "+mTblCountArray[4]); 
      Log.i(Constants.TAG_DBHELPER, "getCountAllc(): Alliance No. of Missions: "+mTblCountArray[5]); 
     } 
    } catch (Exception e) { 
     Log.e(Constants.TAG_DBHELPER, "getCountAllc(): Exception while getting record count:"); 
     Log.e(Constants.TAG_DBHELPER, "getCountAllc(): Cause: "+e.getCause()); 
     Log.e(Constants.TAG_DBHELPER, "getCountAllc(): Message: "+e.getMessage()); 
     e.printStackTrace(); 
    } 
    return mTblCountArray; 
} 

我在一个总损失并欢迎该会指出我在正确的方向上没有任何提示。当我知道100％时，数组中的所有数字都是'0'，它们应该大于'0'。查询的“扇区”和“联盟”参数是有效的，并存在于数据库的查询表中。

谢谢！

原来这个功能确实有效;问题在于我输入的特定数据。
