Check if a string is all-caps in Emacs lisp? -

-

all. I was wondering if Imax Lispi has a function that checks whether a string is completely out of capitalized characters or not. Here's what I'm using now: 

  (set-capitalist-letter-string-to-list "ABCDEFGJKLMOPCRSTWVX")) (DUUPP-R-Capitol (return) If there is a capital letter in the list of characters, each letter is a capital letter. In the form of a special case, the empty list returns are correct. "(Bracket ((same list-letter zero) T ((no member (car list (characters) Letter-of-ak () "(Defun string-capitalized (string)" really gives if a string is a capital letter in each character, an empty string return is correct. "(Letter-by-capital (string-to-list) It works fine (though it depends on the assumption that I will only use ASCII characters), but I was wondering if I remember some explicit function I am coming to know   
 
 
 In the context of other answers:  
     
  1.  
      Use of your  is  not  is a good idea: it will allocate a new string, it will not be found that the string has non-alphabet characters (it seems that you It's better to use  string-match , and  
    2.  
  2.  
     
    3.  As all of these problems solve tray shows, you need to do this when  EX-fold-search  is  zero  otherwise Alex can treat it as a case-insensitive search but  string-match-p  is better because it Match data avoids changing. (Emacs keeps the data after any match, and if you use  string-match , you'll overwrite it, which can break the code using your function.) < Another issue is regexp, using  "^ ... $"  means that Emacs will see some line with some matching content. - And if you have newline characters in your string, then it can return a bogus result you can get backslash-descend and backslash-ud Chevron will use the match from the beginning of the string and the end.  
 
 Then there is a correct version: 
 
  (defun string-is-capitalized (str) (let ((case-fold-search noil)) ( String-match-P "\\` [AZ] * \\ '"str))  
 
 ( -p  in general relation in BTW, AMX Lisp For predicates, use it as  string-capitalized-p .)

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'
