how to code a condition: 'can this string be converted into a date type'? (ruby) -

-

Can I code this condition in some way in Ruby? I need to know the if any string can be converted to a date , the only way to do this is date.parse ("my string") and the exception is there any other way? 

  date_scraped_from_the_net = "20 December 2009" or "Today" if date_scraped_from_the_net is not of date type need_to_be_updated = true end

If you need a sophisticated date parsing, I will try.

However, if I understand your specific question, you would like to use Rescue to conditionally use methods to increase errors: 

  if (date.parse (date_scraped_from_the_net) salvage zero) need_to_be_updated = true end

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'
