Subject Re: Help needed with Postgres Varchar [] -> String [] - Repost
Date Mon, 14 Feb 2005 19:16:29 GMT
So, in Postgres, its an array of Varchar?! That seems awfully odd, but
I'm not that familiar with Postgres. If this is not in fact the case,
and you're create a Varchar(10) (length of 10) - then that should be
mapped to a simple String object, not an Array of String (String[]).
