SQLiteException：接近「INTO」：語法錯誤（代碼1）：

-4

我正面臨着一個錯誤：我確定它不是很多，但我有點卡住它！我發現了一個錯誤，而compilate：SQLiteException：接近「INTO」：語法錯誤（代碼1）：

SQLiteException: near "INTO": syntax error (code 1): , while compiling: UPDATE INTO (PartListDetail(ProductID,ProductName,Quantity) VALUES('','null','0');)

如果有人可以幫助這將是非常好的（我的英語很抱歉）

這是我DataBase.class和我Cart.class：

數據庫

public class Database extends SQLiteAssetHelper { 
    private static final String DB_NAME="myBrickList.db"; 
    private static final int DB_VER = 1; 
    public Database(Context context) { 
     super(context, DB_NAME, null, DB_VER); 
    } 

    public List<PartList> getCarts(){ 

     SQLiteDatabase db = getReadableDatabase(); 
     SQLiteQueryBuilder qb = new SQLiteQueryBuilder(); 

     String[] sqlSelect = {"ProductName","ProductID","Quantity"}; 
     String sqlTable = "PartListDetail"; 

     qb.setTables(sqlTable); 
     Cursor c = qb.query(db, sqlSelect, null, null, null,null, null); 

     final List<PartList> result = new ArrayList<>(); 
     if(c.moveToFirst()) 
     { 
      do{ 
       result.add(new PartList(c.getString(c.getColumnIndex("ProductID")), 
         c.getString(c.getColumnIndex("ProductName")), 
         c.getString(c.getColumnIndex("Quantity")) 
       )); 
      }while (c.moveToNext()); 
     } 
     return result; 

    } 


    public void addToCart(PartList partList) 
    { 
     SQLiteDatabase db = getReadableDatabase(); 
     String query = String.format("INSERT INTO PartListDetail(ProductID,ProductName,Quantity) VALUES('%s','%s','%s');", 
       partList.getProductID(), 
       partList.getProductName(), 
       partList.getQuantity()); 

     db.execSQL(query); 
    } 


    public void UpdateToCart(PartList partList) 
    {

       partList.getProductID(), 
       partList.getProductName(), 
       partList.getQuantity()); 

     db.execSQL(query); 
    }

UPDATE語句的語法不同於INSERT語句。去谷歌上查詢。 – Eran

[Android中的SQLite的可能重複如何更新特定的行]（https://stackoverflow.com/questions/9798473/sqlite-in-android-how-to-update-a-specific-row） –

UPDATE INTO '不存在 –

語法UPDATE查詢

UPDATE table_name 
SET column1 = value1, column2 = value2, ... 
WHERE condition;

您正在使用UPDATE INTO。沒有這樣的命令。

使用

UPDATE PartListDetail SET ProductID=%s,ProductName=%s,Quantity=%s;

或

SQLiteDatabase db = this.getWritableDatabase(); 
    ContentValues contentValues = new ContentValues(); 
    contentValues.put("ProductID", ProductIDValue); 
    contentValues.put("ProductName", ProductNameValue); 
    contentValues.put("Quantity", QuantityValue); 
    db.update("PartListDetail", contentValues, "id = ? ", new String[] { Integer.toString(id) });

感謝您的快速回答，但我有一個錯誤： –

SQLiteException：接近「，」：語法錯誤（代碼1）：，編譯時：更新PartListDetail SET ProductID =，ProductName = null，Quantity = 0 ; –

您沒有正確設置數據。 partList.getProductID（）和getProductName（）返回錯誤的數據。 –

public void UpdateToCart(PartList partList) 
    { 
     SQLiteDatabase db = getReadableDatabase(); 
     String query = String.format("UPDATE PartListDetail SET ProductID=%s,ProductName=%s,Quantity=%s;", 

       partList.getProductID(), 
       partList.getProductName(), 
       partList.getQuantity()); 

     db.execSQL(query); 
    }

我沒有看到我'錯了，感謝您的答案。
