^ Sorted arrays
155064 [ruby danb64.] I'm a relative newcomer to Ruby.  Most of my experience is in Delphi.  And in Delphi one of the most commonly-used classes is TStringList, which is sort of analogous to ruby's Array (Delphi also has dynamic arrays and static arrays).  TStringList has a property called Sorted, which if set to True makes it possible to insert strings into the list and have it maintain them as a sorted list (without having to re-sort it each time).  Then you can use the IndexOf method (or the Find method) to do a binary search on the list, so you can quickly find the element you're looking for.  My question is whether Ruby has anything like this.  It seems like one could create a descendant of Array that does this.
+ 155067 [bob.news gmx] This comes up once in a while.  I think there is an implementation of a
| + 155073 [Ara.T.Howard] it'd be great if it were part of the stdlib imho...
| | 155263 [martindemell] martin
| | 155270 [Ara.T.Howard] thanks!  i'll vote - just as soon as i can remember my password... ;-)
| + 155098 [ruby danb64.] Thanks for the help.  I switched it to use a Hash, and that performed MUCH better.  The data is not coming from any SQL server--it is just a flat file.  The Ruby script processes it into a format so that it can be BCP'd into MS SQL Server.  And when the table that it gets BCP'd into has a unique constraint on the MD5 hash field--hence the need for me to eliminate the duplicate values beforehand.  Granted, I could have changed the process of importing the data so that this unique constraint was not necessary, but it seemed better to me to eliminate the duplicates using Ruby in this case.
|   155164 [bob.news gmx] If you're on MS SQL Server there's another option: you can use an index
|   155182 [ruby danb64.] Yes, but that would sort of defeat the purpose.  The point is, I don't WANT the duplicates.  Otherwise I could simply do away with the unique constraint altogether and then just write something in T-SQL to remove any duplicates after the data is BCP'd in.  But, since I'm creating this .DAT file for BCP which is going to be BCP'd into quite a few SQL databases, it is much better for me to just eliminate the duplicates from the .DAT file.
|   155185 [bob.news gmx] You don't with option IGNORE_DUP_KEY (see the page I referenced): with
|   155227 [ruby danb64.] Ah, OK.  I'm finally getting this through my thick skull.  :-)  That sounds pretty cool, I wasn't aware you could do that (have it just skip the duplicates).  But, hey, I've already coded it in Ruby using a hash, which seems to work fairly well.  And this isn't the kind of thing that I'll be running every day--maybe once a month, if that.  So the Ruby solution works just fine for me.  It's a little slower than it was before, but not a lot.  Believe me, it was *really* bad the way I was doing it using an unsorted array.
+ 155069 [huber.philip] should your list be sorted in the end? if not, you could simply use
+ 155072 [hgs dmu.ac.u] If you wish to remove duplicate items, read about uniq ...
  155074 [Ara.T.Howard] what did you end up doing?  i forgot you were working with csv data - did you
  + 155076 [pit capitain] Interesting. What types of keys and values did you use?
  | 155087 [Ara.T.Howard] strings => lists of strings
  + 155078 [hgs dmu.ac.u] I found that the real time-killer was the CSV library itself.  This
    155089 [Ara.T.Howard] this is exactly the approach i always use with csv: i split the first line,
    155113 [hgs dmu.ac.u] Oh, that's rather neat.
