How does the xml:lang & lang attribute affect the rendering of XHTML Strict 1.0 pages? -

-

I looked inside the source of a public website which uses XHTML 1.0 strict DOCTYPE and found that it has two characteristics Is related to the language of the page 

  & lt; Html xmlns = "http://www.w3.org/1999/xhtml" xml: lang = "ja" lang = "ja" & gt;

The page is in Japanese on the way. My question is: -

I suspect that the attribute is xml: lang & amp; Lang does not affect the rendering of the page in the browser. This HTTP header has content-type that specifies the encoding of the page. Am i right

say:

Specified information through language different ways To control rendering, the lang feature can be used by the user agent. In some situations where the information given by the author can be useful, it includes:

  • Support Engine Assistance
  • Speech Synthesizer Help
  • Select the type of glyph to help the user agent
  • Helping the user agent choose a set of quotation marks
  • A user agent Hyphenation, Lignec And help to make decisions about spacing
  • Magic help checkers and grammar checkers

In addition, I will not think that this layout Or document mode (standard mode versus quirks mode). This is a very standard reference when it comes to such things, and there is no mention of the Lang character while searching for that site.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
