Hi,

the db-library manual page is slightly ambiguous and confusing on this
point,
and I'm not sure that freeTDS behaves exactly like Sybase or SQl server
db-lib in this respec.t

Using Freetds though, it is not valid to call dbhasretstat until you have
processed all the results using dbresults()

In other words, you should move those calls after the "while...dbresults"
loop
