答案 0 :(得分：0)
db.execSQL("CREATE_TABLE "+ TABLE_NAME_HIGH +" (_id INTEGER PRIMARY KEY AUTOINCREMENT, "
+ COL_CODE_TREE + " VARCHAR, " + COL_HIGH_TREE + " INTEGER, "+ COL_STATUS_HIGH + " TEXT, " + COL_DATE_HIGH + " DATE);");
这里你没有在create query中查看列名highId。查看它。
答案 1 :(得分：0)
使用KEY_ID代替highId
public static final String KEY_ID = "_id";
Update High set udpateStatus = 'no' where "+ KEY_ID +"='?'
答案 2 :(得分：0)
您正在onCreate()方法中创建列名为 _id 的表格，
＆安培;尝试在 highID 列中添加数据。
因此，此错误适用于列名称不匹配。
更新db.execSQL中的onCreate()方法，如下所示：
db.execSQL("CREATE_TABLE "+ TABLE_NAME_HIGH +" (highID INTEGER PRIMARY KEY AUTOINCREMENT, "
+ COL_CODE_TREE + " VARCHAR, " + COL_HIGH_TREE + " INTEGER, "+ COL_STATUS_HIGH + " TEXT, " + COL_DATE_HIGH + " DATE);");
