The answer I am talking about is this. I don't feel I have enough evidence to flag this answers so it gets removed, however it is wrong, but seems useful and that is why it has a lot of up-votes.
At first sight I thought it was good, however when he said the Functions can not accept exceptions, I found it weird, but since I don't know so much about Oracle I thought he was right.
Then I read the answers' comments and notice Jon Heller pointed out errors on it. I normally read the comments, but not everyone does.
For me the information conveyed in that question is for SQL Server. There can be doubts about the Table itself, but when he categorizes the User Defined Functions, he uses the categories commonly used for SQL Server. As you can see here.
I haven't seen User defined functions categorized in that way. Specially the last category is not a term used in Oracle, as you can see here.
I would like to point out that this question is one of the top hits in Google when searching about "functions vs procedures in oracle".
I realize this is a bit of a subjective case, since the poster didn't identify his source of information, so, what can I do to get this question removed?
