Subject [jira] Commented: (DBUTILS-17) [dbutils] ScalarHandler subclasses that return Integers and Longs
Date Thu, 06 Jul 2006 11:39:30 GMT
    [ ] 

greg hawkes commented on DBUTILS-17:

No problem, Henri. I assume that you're referring to issue
I realise that this issue tackles a similar problem to my own, but I believe that mine is
a more general solution to a wider range of problems. In fact, DBUTILS-27 would be simple
to implement using a call to my IntScalarHandler routine.

> I (and, looking around, many other people) most often use ScalarHandler to fetch
> the result of an SQL count(*) column. ScalarHandler works, but I was forever
> needing to parse the result to create an Integer (and occasionally, a Long)
> value. Several possible solutions have been proposed to make this task easier.
> This is mine.
> I have extended ScalarHandler to create IntScalarHandler and LongScalarHandler,
> which return Integers and Longs, respectively. Their usage is exactly the same
> as ScalarHandler. They have been tested on Oracle, MS-SQL Server, and PostgreSQL
> databases, and have proven to be very effective. I hope that they can be
> included in the DbUtils distribution, where they fit right alongside the
> existing ScalarHandler.
