Hi all,
I am trying to optimize the queries in my application. Is there a performance difference between (to_char(myDate ,format) < myString) and (myDate < to_date(myStrin g, format)).
ex. Select * from myTable where (to_char(fieldD ate, 'MM/DD/YYY') <= queryDate )
or Select * from myTable where (fieldDate <= to_date(queryDa te, 'MM/DD/YYYY') )
assuming fieldDate is a date or timestamp field and queryDate is '01/01/2007', a string.
Also, does it matter if the to_date or to_char condition is listed before or after the string variable? Thank you for your help.

Dear usenet,
I'm having the following small problem.
I've been ask to add some Quicktime panoramas to a website. The author of
the panoramas has made two versions of each: One in MOV format, which needs
a Quicktime plugin, and one Java applet. He's also kindly supplied me with
sample HTML code for each.
The code looks like this (simplified):

This is a two-part question to which I haven't been able to find an answer
anywhere else.
1. Is it possible to format the bullet/number character of the <li>? In my
styles sheet, I have the <li> tag formatted, for example, bold. However,
when it's applied, the number of the <li> is not bold, but the text is. Do I
have to apply the bold to the <ol> instead?
2. When I use <li>example text</li>, and when I insert a <br> after the

This is probably a very obvious question, but I'm not clear on what
operators need to be implemented for std::map.find() to work. For
example, I have a class MyString that wraps std::string, and which also
implements ==, <, <=, >, >=, etc. (Those operators are tested and
working correctly.)
If I assign map = "world", it saves the MyString's correctly
in the map. But a subsequent call to map.find("hello") returns
map.end(). Even more...

I have been researching articles on google on how to create a simple RSS
feed that sucks <title><blurb><link><date> out of a sql server 2000 database
via an aspx page.
I know it has to be pushed into a <xml> document but not sure which
direction to take.
Is there perhaps a starter document which uses sql server as the data source
I can tap into.

Dear folks,
In Javascript, is it possible to get all id names within, say, a
<div></divpair? Like the array of "document.images", I mean.
The reason I ask, is that I have a calender whose <td></tdtable
elements, within a given <div></div>, all have a class type, one of which
is "today" (to highlight it). Once the calender is drawn, the Javascript
has ended. And since Javascript has no known (to me) method of storing
variables in say,...

The only browser I have encountered that supports
<colgroup><col class="behold"></colgroup>
to apply a CSS style to a whole column, is Microsoft Internet
Explorer. I have been told it SHOULD NOT do so, since this is not
part of the specification.
How then to you apply styles to entire columns? Surely you don't have
to write
<td class="behold"on every row item.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
