的Android SQLite的CREATE TABLE語法錯誤

我收到以下錯誤，當我在我的應用程序執行SQL：的Android SQLite的CREATE TABLE語法錯誤

android.database.sqlite.SQLiteException: near "(": syntax error (code 1): , while compiling: CREATE TABLE IF NOT EXISTS data (id int auto_increment primary key, data_type int default 0, data float not null, time timestamp default now());

代碼導致錯誤：

@Override 
public void onCreate(SQLiteDatabase db){ 
    db.execSQL("CREATE TABLE IF NOT EXISTS " + DATA_TABLE + " (id int auto_increment primary key, data_type int default 0, data float not null, time timestamp default now());"); 
}

logcat的

我已經通過語法錯誤檢查器來運行行本身，它似乎很好。

將代碼添加到出現錯誤（創建表部分）和完整logcat的位置。 – 2014-12-11 05:16:50

的錯誤是由於default now()

嘗試使用這樣的：

CREATE TABLE IF NOT EXISTS data (id int auto_increment primary key, data_type int default 0, data float not null, time timestamp default current_timestamp);

檢查：SQLite - default a datetime field to the current time (now)

希望它能幫助。

它必須是你的表名。「數據」是許多關鍵字之一，主要用於各種編程語言，查詢語言......

所以你應該嘗試別的名字。無論如何，「數據」似乎並不是一個有意義的名字，程序員應該在命名變量時養成良好的習慣......
