那么，我想要做的是在第一次安装中的uodate我的应用程序。因此，在第一次访问时，我的应用程序具有访问CallLog的服务，并检索所有数据并插入到应用程序数据库中。android.database.sqlite.SQLiteException：表contact_data没有列名timestamp_
而我有一列timestamp_，我想插入呼叫的时间戳。但是当我尝试插入它时，表中没有列名为timestamp_的列，并且它明确地在sql字符串中写入了该列的名称。我不知道它为什么这样做。
我的CREATE TABLE字符串写在strings.xml，我访问这个字符串并分割它获得每一行。
这是服务的代码，SQL字符串，并且存在DataHandlerDB的代码之后，它具有创建数据库的方法。
我的服务：

@Override

}
}
private void execMultipleSQL(SQLiteDatabase db, String[] sql) {

}
@Override
public void onOpen(SQLiteDatabase db) {
super.onOpen(db);
}
}
}
SQL字符串（在strings.xml中声明）：
<string name="My_OnCreate">
"CREATE TABLE IF NOT EXISTS contact_data (_id INTEGER PRIMARY KEY AUTOINCREMENT, contact_id INTEGER, contact_name VARCHAR(50), number_type VARCHAR(50), contact_number VARCHAR(50), duration TIME, duration_sum TIME, date DATE, timestamp_ VARCHAR(50), current_time TIME, cont INTEGER, type VARCHAR(50), month VARCHAR(50), day VARCHAR(50), year VARCHAR(50));

CREATE TABLE IF NOT EXISTS months_dur (_id INTEGER PRIMARY KEY AUTOINCREMENT, month VARCHAR(50), duration TIME, year VARCHAR(250), month_num INTEGER);"
</string>
下面是从logcat的误差：
06-13 18：58：05.041： INFO /数据库（2121）：源码返回： 错误代码= 1，味精=表 contact_data没有指定列 timestamp_
06-13 18：（2121） ERROR /数据库：：58：05.081错误插入 contact_number = 1234545 持续时间= 00：00：05 CONTACT_ID = 1 timestamp_ = 1307928304514 NUMBER_TYPE = 0 CONTACT_NAME =的current_time = 18：58：4 类型= 2 CONT = 1个日期= 6 /二千零十一分之十三06-13 18：58：05.081：

错误依然存在time_stamp。 PS：我只是把它命名为时间戳，而且我认为它是原因，我将它命名为timestamp_，错误依然存在。但这不是问题，因为第二个sql语句（声明表rated_contacts）创建此列，但不是第一个表。 – rogcg 2011-06-14 00:00:43
