Here is the Solution:
Martin Evans on the dbi-user mailing list was able to finally find the source of this error, here is the text of his reply:
I analysed your log and did the same thing in
ODBCTest which used to come with MDAC and it fails in the same way:
SQLPrepare(print 's' select count(*) from table print 'e')
SQLNumResultCols()
returns SQL_ERROR and invalid cursor state.
so, I'm afraid, there is no bug in DBD::ODBC and the problem is in the MS
SQL
Server driver. Interestingly, our ODBC-ODBC Bridge makes you code almost
work
because it inserts a call to SQLNumParams between the SQLPrepare and the
SQLNumResultCols and that puts the MS SQL Server Driver into a different
state. I say "almost" because it does appear to hightlight another bug in
the
MS SQL Server driver later on where SQLMoreResults returns SQL_NO_DATA but a
later call to SQLNumResultCols returns 1 column and this persuades DBD::ODBC
there is a column and it fails on a call to SQLDescribeCol (because
SQLNumResultCols lied and there is no result-set).
Your only choice is to take the prints out.
I ended up building DBI 1.45 and DBD::ODBC 1.11 on my machine.
I was still able to achieve the desired result by using a suggestion our DBA made of substituting a SELECT everywhere there is a PRINT and that seems to work nicely. For statements that return multiple result sets I ended up using the following:
#!C:/perl/bin/perl -w
#DBI 1.45
#DBD::ODBC 1.11
use DBI;
$dbh = DBI->connect("dbi:ODBC:tmpDB", 'username','password',
{ PrintError => 1, RaiseError =>0, LongReadLen => 65536,
odbc_async_exec => 1, odbc_err_handler => \&errSub }
);
$command = qq/
select 'start'
select name = 'dbi-user'
select 'end'
/;
$sth = $dbh->prepare($command);
die $DBI::errstr unless $sth;
my $rc = $sth->execute();
do {
my @row;
while (@row = $sth->fetchrow_array()) {
print join(",", @row), "\n";
}
} while ($sth->{odbc_more_results});
$dbh->disconnect;
sub errSub {
my ($state, $msg) = @_;
# Strip out all of the driver ID stuff
$msg =~ s/^(\[[\w\s]*\])+//;
my $err_text .= $msg."\n";
print "Err($state):",$err_text;
}
Thanks to all who responded.
