Android 5.0 SQLITE 插入失败

Question

每次我尝试在数据库中插入数据时，我都会遇到一个奇怪的错误：

Error inserting date=1439183960 amount=5.0 icon=1 description=g or_amount=0.0 lat=0.0 long=0.0
android.database.sqlite.SQLiteException: table transactions has no column named icon (code 1): , 
while compiling: INSERT INTO transactions(date,amount,icon,description,or_amount,lat,long) VALUES (?,?,?,?,?,?,?)

错误表明 table icon 没有列 icon

这是我创建的查询：

@Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL("CREATE TABLE IF NOT EXISTS transactions (" +
                "id INTEGER PRIMARY KEY AUTOINCREMENT, " +
                "amount REAL, " +
                "or_amount REAL, " +
                "description TEXT" +
                "icon INTEGER, " +
                "lat REAL, " +
                "long REAL, " +
                "date INTEGER" +
                ")");
    }

这是将一些实体插入数据库的方法：

public long insert (Entitie entitie) {
        long NO_INSERTED_ENTITIE = -1;
        long id = NO_INSERTED_ENTITIE;

        getWritableDb();

        if (entitie.getId() == NO_INSERTED_ENTITIE){
            id = db.insert(entitie.getTableName(), null, entitie.getContentValues());
            entitie.setId( (int) id );
        }
        return id;
    }

这里是实体，它被称为 PaymentLog:

public class PaymentLog extends Entitie{

    //====== tables fields======

    private static final String tableName = "transactions";
    private static final String[] columnNames = {"id", "amount", "or_amount", "description", "icon", "long", "lat", "date"};
    private final int ID_POSITION = 0, AMOUNT_POSITION =1, OR_AMOUNT_POSITION = 2, ICON_POSTION = 4, LONG_POSTION =5, LAT_POSTION=6, DATE_POSTION=7, DESCRIPTION_POSTION = 3;

    @Override
    public ContentValues getContentValues(){
        ContentValues content = new ContentValues();
        content.put( columnNames[ AMOUNT_POSITION ], this.getTransaction());
        content.put( columnNames[ OR_AMOUNT_POSITION ], this.getOriginal_amount());
        content.put( columnNames[ ICON_POSTION ], this.getIcon() );
        content.put( columnNames[ LONG_POSTION ], this.getLang() );
        content.put( columnNames[ LAT_POSTION ], this.getLat() );
        content.put( columnNames[ DATE_POSTION ], this.getDate().getTime()/1000 );
        content.put( columnNames[ DESCRIPTION_POSTION ], this.getDescription() );
        return content;
    }

    public String getTableName() {
        return tableName;
    }

}

我不知道为什么会出现此错误，我的创建查询是正确的，我从 phone 中清除了缓存和应用程序数据，以使用 onCreate 方法重建数据库。我的 class PaymentLog 它也是正确的，我不知道它有什么问题，我听说 Android 5.0 上的 sqlite 有一些变化，但我不知道是否插入有变化。

问题出在您的创建 table 语句

you haven't added comma after description Text

所以试试

 db.execSQL("CREATE TABLE IF NOT EXISTS transactions (" +
            "id INTEGER PRIMARY KEY AUTOINCREMENT, " +
            "amount REAL, " +
            "or_amount REAL, " +
            "description TEXT, " +
            "icon INTEGER, " +
            "lat REAL, " +
            "long REAL, " +
            "date INTEGER" +
            ")");

您需要仔细查看查询中的逗号和空格，否则您的查询将无法运行正确。
