RE: SQL errors not making it back to Perl

Oho!  Here is a clue.  I removed

    odbc_cursortype => 2

from the DBI->connect attributes.  Now the error is trapped!
The output was:

    handle_error: $state  is "42000".
    handle_error: $msg    is "[Microsoft][ODBC SQL Server Driver][SQL
Server]An error was raised. Input was "Some input parameter".".
    handle_error: $native is "50000".
    After execute: $retval is "55".
    After execute: $p1     is "Some input parameter".
    After execute: $p2     is "75".
    Done.

Now I wonder a) why I put odbc_cursortype=>2 in there in the first place
(I've been doing that for years), and b) why that breaks things.
