The best way to generate SQL execution plans
Double-speak for "you're fired"
select posts from sqlfail
Although we know that in the case when we do select from a table and one of the predicates is “field=:bind_variable” and :bind_variable is null, we should not get the rows, oracle not always “think” the same and don’t add upper filter predicate “:bind_variable is not null”, so it can do unnecessary work. It is completely depends from a plan, which will be chosen. Of course this applies to other predicates like >, < or != too.
I will explain, how you can send files using ANT scipt over SFTP protocol.
Until i find how to use sftp protocol, I googled also ftp protocol. I will explaint it firstly,
If you want to use FTP protocol, you may use
where trunc(i_want_all_the_times) =
to_date (:on_this_date, 'dd/mm/yyyy')
and the_numbers + 1 = :one_less_than_this
and instr(text, :starting_with_this) = 1;
where i_want_all_the_times >=
to_date (:on_this_date, 'dd/mm/yyy

I had an interesting conversation about table functions in Oracle’s PL/SQL; and the fact that they’re not available in MySQL. When I explained they’re available in Microsoft T-SQL User-Defined Functions (UDFs), my students wanted a small example. One of them said they’d tried to do it but couldn’t get it to work because they found the Microsoft web pages difficult to read and use. Specifically, they didn’t like the sparseness of this one on how to create a function.
In previous part i already point out that:
create table physically_ordered_data (

I recently did a comparison caching mechanisms of scalar subquery caching(SSC) and deterministic functions in 11.2. Unfortunately, I do not have enough time to do a full analysis, so I will post it in parts.
Thirty-two players competed in the Q4 2012 championship. This was our smoothest competition to date; only player experienced a minor problem and our reviewers did such a great job that no errors were found in our quizzes - a significant accomplishment given the complexity of the quizxes.
You will find below the rankings for the championship; the number next to the player's name is the number of times that player has participated in a championship.
Congratulations first and foremost to our top-ranked players:
