September 15, 2011

Is it possible to understand the difference between the concat () function and in the oracle Operator?

Which is better in terms of performance?

  There is no functional difference.  
  ||  ANSI is the standard string concatenation operator (though, unfortunately, to support every database  & lt; cough & gt; SQL Server & lt; / cough & gt;  standard) Databases support a  CONCAT  function, so using port code for different databases can be easy.

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -

App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,
