Android中的两个表（SQLite）

我正在尝试在Android的一个数据库中创建两个表。但是我仍然有一个错误，也不知道该怎么办。

这是我的DbHelper类

private static final String DB_NAME="DBbudik";
private static final int DB_VER = 2;
//public static final String IDevent = "IDevent";
//Tabulka pre poznámky
public static final String DB_TABLE="Task";
public static final String DB_COLUMN = "TaskName";
//Tabulka pre udalosti
public static final String DB_TABLE2="DayEvent";
public static final String DB_COLUMN1="DayEventName";
public static final String DB_COLUMN2="DayEventPlace";
public static final String DB_COLUMN3="DayEventTime";
public static final String DB_COLUMN4="DayEventDate";
public static final String DB_COLUMN5="DayEventNote";



public DbHelper(Context context) {
    super(context, DB_NAME, null, DB_VER);
}

@Override
public void onCreate(SQLiteDatabase db) {
    String query = String.format("CREATE TABLE %s (ID INTEGER PRIMARY KEY AUTOINCREMENT,%s TEXT NOT NULL);",DB_TABLE,DB_COLUMN);
    String query2 = String.format("CREATE TABLE %s (ID INTEGER PRIMARY KEY AUTOINCREMENT, %s TEXT NOT NULL, %s TEXT NOT NULL, %s TEXT NOT NULL, %s TEXT NOT NULL, %s TEXT NOT NULL);",DB_TABLE2,DB_COLUMN1,DB_COLUMN2,DB_COLUMN3,DB_COLUMN4,DB_COLUMN5);
    db.execSQL(query);
    db.execSQL(query2);

}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    String query = String.format("DELETE TABLE IF EXISTS %s",DB_TABLE);
    String query2 = String.format("DELETE TABLE IF EXISTS %s",DB_TABLE2);
    db.execSQL(query);
    db.execSQL(query2);
    onCreate(db);
}

出现此错误，它指向第50行：

它在那里显示错误。这是第50行

db.execSQL（query）;
