unicode - (grep) Regex to match non-ASCII characters? -

-

On Linux, I have a lot of files, some of them have non-ASCII characters, but they all are valid. There is a bug in a program that prevents it from working with non-ASCII filenames, and I have to find out how many impressions I was going to do with this search and then the non- ASCII used to print the characters, and then do a wc -l to find the number. It does not have to be grep; I can use any standard UNIX, such as ,,, etc.

However, is there a regular expression for 'any letter that is not ASCII character'?

This will match a non-ASCII character: 

  [ ^ \ X00- \ x7F]

This is a valid ( Perl-compatible regular expression ).

You can also use the shorthound:

  • [[ascii:]] - matches a single ASCII character
  • [^ [: ascii:]] - matches a single non-ASCII letter

[^ [: Print:]] Maybe it will be enough for you. **

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'
