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,因为我已经把这个价值作为一个关键.
所以在这种情况下,我做了一个sqliteConstraintException的捕获,但是当我运行代码时,我从来没有在catch中.

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.
