Damn!

Yesterday, I found my code's bug about getting data from Oracle DB. I tested again and again, wasted my time so much, but I failured and fount the bug is good in another pc finally. So I gived up to sleep.

Today, I googled the bug, but I cannot get any useful information. I think it is maybe  a problem from the os. Then I reinstall the Oracle, rebuild the circumstance, oh, my god, all is good. Damn, the Oracle itself have a problem.
