如何删除 CURRENT_TIMESTAMP 列？

Question

问题：

我有 table [ INFOTABLE ] 时间戳列名为 DATETIMESTAMP [INTEGER] 数据类型。
我需要使用此列删除记录，但删除查询抛出错误。
主要是因为捕获的时间戳之间有T[TIME indicator]。 [例如：] 2020-01-01T17:45:31.127452+03:00[Asia/Riyadh]

SQLITE TABLE:

  String create_sql3 = "CREATE TABLE IF NOT EXISTS " + Tablename3 + "("
                    + SNO + " INTEGER NOT NULL," + ITEM + " INTEGER NOT NULL,"
                    + DATETIMESTAMP + " INTEGER DEFAULT CURRENT_TIMESTAMP )";

删除查询：

db.execSQL("DELETE FROM " + Tablename3 + " WHERE DATETIMESTAMP = " + Integer.parseInt(deltimestamp.get(y))  + ";");

异常记录：

android.database.sqlite.SQLiteException:
unrecognized token: "01T17" (code 1):,while compiling: DELETE
FROM INFOTABLE WHERE DATATIMESTAMP = 2020-01-01T17:45:31.127452+03:00[Asia/Riyadh];

此处 deltimestamp 是一个字符串数组列表，其中日期时间戳为字符串。感谢有关 CURRENT_TIMESTAMP 列的删除查询更正的帮助！

Answer 1

将table保存为timestamp(Long Value : 1231413123) 这样您在删除过程中查询相关值会更方便

样本Table；

CREATE TABLE MyTable(
        ID INTEGER PRIMARY KEY,
        Foo TEXT,
        Bar TEXT,
        Timestamp DATETIME DEFAULT CURRENT_TIMESTAMP
    );

已解决问题！[=25=]

查询（错误）：

db.execSQL("DELETE FROM " + Tablename3 + " WHERE DATETIMESTAMP = " + Integer.parseInt(deltimestamp.get(y)) + ";");

查询（固定）：

db.execSQL("DELETE FROM " + Tablename3 + " WHERE DATETIMESTAMP = " + "'" + deltimestamp.get(y) + "'" + ";");

或

db.execSQL("DELETE FROM " + Tablename3 + " WHERE DATETIMESTAMP = "+ "'" + cursor.getString(7) + "'" + ";");
