My goodness, such hostility in your posts. This board would benefit from you eliminating your own "tripe" as you call it. (or from you leaving the board entirely.) I've read time and time again posts from you filled with hostility and snotty comments. You bring nothing but bad energy to this board and the Oracle community. Feel free to either stop responding to every post with your snotty attitude ... OR better yet, leave the board entirely!

The OP posted a very kind question seeking clarification (in the most recent post.) And yes, there are GENERIC questions/answers in Oracle! Example: Can export/import be used to move a table from 1 database to another? You can just answer YES .... there are ALWAYS circumstances where it won't work (character sets, platforms, etc.) ... but the answer is YES. Just leave it at that. Don't be such a rude responder. If all you can do is be rude, DON'T ANSWER!!!!! Is that too difficult for you? Received on Tue Oct 21 2008 - 09:30:00 CDT
