我在将数据和时间插入sq-lite数据库时遇到错误,当我在表格中插入日期时间列时出现错误。

我在create table命令中有日期时间列,但后来我也收到了错误。

3 个答案:

答案 0 :(得分:2)

您在create语句中缺少KEY_TIMEST及其数据类型之间的空格:

arg0.execSQL("CREATE TABLE " + DATABASE_TABLE + "(" +
                KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
                KEY_NAME + " TEXT NOT NULL, " +
                KEY_AMOUNT + " INTEGER NOT NULL, " +
                KEY_RATE + " INTEGER NOT NULL, " +
                KEY_TIME + " INTEGER NOT NULL, " +
                KEY_TIMEST + " DATETIME NOT NULL);" // space added here
        );

答案 1 :(得分:0)

arg0.execSQL("CREATE TABLE " + DATABASE_TABLE + "(" +
                    KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
                    KEY_NAME + " TEXT NOT NULL, " +
                    KEY_AMOUNT + " INTEGER NOT NULL, " +
                    KEY_RATE + " INTEGER NOT NULL, " +
                    KEY_TIME + " INTEGER NOT NULL, " +
                    KEY_TIMEST + " created_at DATETIME DEFAULT CURRENT_TIMESTAMP);" //this way works fine

适用于Long和String值,使用字符串我得到完整的格式化日期,而使用long我得到一个很长的数字,这对于稍后操作日期非常有用

答案 2 :(得分:-2)

您在数据库中将时间列定义为INTEGER并且它没有问题,因为时间可以存储为INTEGER或TEXT,但是当您尝试插入新行时,您会给它一个字符串。也许将时间转换为Long来解决您的问题。试一试

    Date d = new Date(); //gives you the current time. 
    Long newTime = d.getTime();
    cv.put(KEY_TIME, newTime);
