原标题:Why does strftime() insert string into integer column

我设立了一栏,即INTEGE,这就是我如何在表格中插入斜点日期:

 ContentValues vals = new ContentValues();
 vals.put(Column._CREATED_DATE, "strftime( %s , now )");
 db.insert(Table.ARTICLE.name, null, vals);

毋庸置疑,他插入strftime ( %s , now )string into INTEERT栏!

什么?

EDIT:当我操作inert into article (created) Value (strftime("%s”,”now) in ankouite browser时,插入了适当的惯性价值......

最佳回答

而是在表格中增加一个缺省值,例如:

CREATE TABLE article (
    _id INTEGER PRIMARY KEY AUTOINCREMENT,
    name TEXT,
    _created_date INTEGER DEFAULT (strftime( %s ,  now ))
);

如果你在创建行文时不设定其一栏价值,那么,这就会把一分不变。 如果你想有一个时间序列(例如,2012-05-07 13:07:58),你将这个期限定义为:

_created_date INTEGER DEFAULT CURRENT_TIMESTAMP
