php - How do I echo selected in a while loop? -

-

There are a blog and question sections on my site, which contain categories when a user creates a question or a blog, a drop down The menu that allows you to choose your category. When you edit one of these, you have the option to change your category through the dropdown. When you edit a blog, the category drop down is a standard style dropdown, and I have the & lt; Option value = "1" & lt; Php if ($ blog- & gt; category == "1") {echo "selected";}? & Gt; & Gt; Art & Literature & lt; / Option & gt; I'm picking up to show the pre-selected category where another developer has been left out, so for the question that has been down in the loop. Being a newbie I do not know how to "selectively select" in the loop to pull the last chosen cat. Here is the loop 

  & lt; Select name = "category" & gt; & Lt; Option value = "zero" & gt; Select category & lt; / Options & gt; & Lt ;? Php $ query = "class_name" ASC "classified_selected order; $ Request = mysql_query ($ query, $ connection); While ($ result = mysql_fetch_array ($ request)) {echo "option value = '". $ Result ['id'] "'' & gt; . $ Result ['classname'] "& lt; / option & gt;"; }? & Gt; & Lt; / Select & gt;

You can do it the same way, assume that you have a $ blog object Where this code is undergoing: 

  while ($ result = mysql_fetch_array ($ request)) {$ selected = ($ result ['id'] == $ blog- & gt; category) ? 'Selected =' selected '': ''; Echo "& lt; option value = ''. $ Result ['id']" '". $ Selected." & Gt; $. [' Category '] "& lt; / Option & gt; ";}

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'
