当我运行的代码我有db.insert异常里面：
08-29 15:40:17.519: E/SQLiteDatabase(3599): android.database.sqlite.SQLiteConstraintException: column date is not unique (code 19)
这是正常的，因为我已经有一个价值的关键。 因此，在这种情况下，我做的抓SQLiteConstraintException ，但我从来没有得到过Catch中，当我运行的代码。
我究竟做错了什么？
try {
db.insert(TABLE_STATISTICS, null, values);
} catch (SQLiteConstraintException e) {
Log.d("entered", "entered the exception");
ContentValues valuesUp = new ContentValues();
valuesUp.put((isMT ? KEY_MT : KEY_MO), change);
db.update(TABLE_STATISTICS, valuesUp, KEY_DATE + "=?",
new String[] { message_date });
}
谢谢。
