Android Sqlite查詢

Question

我的要求是當我傳遞一些需要發送對象的參數查詢時。不是列表。

我寫的代碼：

public RDExecutive getExecutiveObject(String executivename){ 
    DBAdapter dbAdapter = DBAdapter.getDBAdapterInstance(this); 
    dbAdapter.openDataBase(); 
    System.out.println(" ---- executivename --- " + executivename); 
    String query="SELECT * FROM RDExecutive WHERE ExecutiveName = ?';"; 
    String[]d = new String[]{executivename}; 
    ArrayList stringList = dbAdapter.selectRecordsFromDBList(query, d); 

    dbAdapter.close(); 

    ArrayList<Object> rdExecutiveObject = new ArrayList<Object>(); 
    RDExecutive rdExecutive = new RDExecutive(); 
    System.out.println(" -- stringList.size() -- " + stringList.size()); 

    for (int i = 0; i < stringList.size(); i++) { 
     ArrayList<Object> arrayList2 = (ArrayList<Object>) stringList.get(i); 
     ArrayList<Object> arrayList = arrayList2; 
     ArrayList<Object> list = arrayList; 

     try { 
      rdExecutive.setBusinessUnit((String) list.get(0)); 
      rdExecutive.setExecutiveCode((String) list.get(1)); 
      rdExecutive.setExecutiveName((String) list.get(2)); 
      rdExecutive.setTerritoryCode((String) list.get(10)); 

     } catch (Exception e) { 
      Log.i("***" + SalesRouteActivity.class.toString(), e.getMessage()); 
     } 
     rdExecutiveObject.add(rdExecutive); 
    } 
    return rdExecutive; 
} 

此方法返回RDExecutive對象。

當我運行這一部分中，我得到了錯誤

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.xont.controller/com.xont.controller.DownlaodTableActivity}: 

android.database.sqlite.SQLiteException: unrecognized token: "';": , while compiling: 
SELECT * FROM RDExecutive WHERE ExecutiveName = ?'; 

我們想傳遞參數查詢怎麼辦。

Answer 1

你不需要semicolong（ 「;」）

String query="SELECT * FROM RDExecutive WHERE ExecutiveName = ?'"; 

應該罰款

Answer 2

你有一個SQL語法錯誤。您需要刪除單引號，即

// This line has the error: 
String query="SELECT * FROM RDExecutive WHERE ExecutiveName = ?';"; 

// This is the same line with the error fixed: 
String query="SELECT * FROM RDExecutive WHERE ExecutiveName = ?;";
