问题描述
当我运行该代码时，我在 db.insert 中有一个异常:
When I run that code I have inside the db.insert an exception:
08-29 15:40:17.519: E/SQLiteDatabase(3599): android.database.sqlite.SQLiteConstraintException: column date is not unique (code 19)
这很正常，因为我已经将该值作为键.所以在那种情况下，我会捕获 SQLiteConstraintException 但我在运行代码时永远不会进入捕获中.
Which is normal, because I already have that value as a key.
So in that case I do a catch of SQLiteConstraintException but I never get inside the catch when I run the code.
我做错了什么?
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.
