Win32 AS-5.8.0 Multithread build 806 DBI(1.43)DBD::ODBC(1.07) MSSQL Server I get a invalid cursor state when I run any SQL with a PRINT statement at the beginning of any SQL statement.
DBD::ODBC::st execute failed: [Microsoft][ODBC SQL Server Driver]Inval +id cursor state (SQL-24000)(DB D: dbd_describe/SQLNumResultCols err=-1) at H:\progs\dbi_test.pl line +10.


Example code:
#c:/perl/bin/perl use DBI; my $dbh = DBI->connect( 'dbi:ODBC:TEST_DSN', '','', {RaiseError=> 1} ) +; my $sth = $dbh->prepare( "PRINT '...begin' select name = 'test' " ); my $rv = $sth->execute(); print "rv: $rv \n"; while ( my $hr = $sth->fetchrow_hashref ){ print $$hr{$_}, "\n" for ( keys %$hr ); print "Err: ", $dbh->errstr, "\n" if $dbh->errstr; }
If you move the PRINT statement AFTER the select statement, you don't get the error, but you also don't see the output of the print.
Does anyone know how to capture the output of the PRINT Statements? They seem to print on command line tools like ISQL and other programs like Embarccadaro. Is my SQL in bad form here or is this a problem I am not working correctly in DBI?
Thanks in advance!

    [ambrus]: Corion: really? Does that mean the Prima watcher objects behave as handles that stop the watcher when they're destroyed, just like AnyEvent expects?
    [ambrus]: "all the bugs" -- hehe, good luck
    [ambrus]: Corion: what I don't understand is, if you make a one-shot AnyEvent timer with short timeout, does this code guarantee that the Prima timer can't queue two timeout events before invoking any of them?
    [ambrus]: Because that could break AnyEvent code, which is why I added a guard.
    [ambrus]: (It might be easier to use the callback scalar as a guard, as in $c and &$c(); $c = ();)
    [Corion]: ambrus: Hurr - yes, that might happen, as Prima will queue lots of stuff (Well, Windows will)
    [Corion]: But I'm really amazed that it just took this little code (plus the idle handler I have in mind and something else dk suggested)
