I couldn't find a reference to $sth->more_results in the documentation,
but I did find a reference to DBI::dum_results($sth).
If I add that to my code (snippet below):
#this one does not
$sql = "test_raiserror2";
print "\n\ntest_raiserror2 - usually doesnt work\n";
$sth = $dbh->prepare($sql);
warn $DBI::errstr if $DBI::errstr;
$rc = $sth->execute();
warn $DBI::errstr if $DBI::errstr;
print "** dumping results: \n";
DBI::dump_results($sth);
print "errstr: $DBI::errstr\n\n";
print "dropped\n\n";
then I get the following results (errstr is set, but it's a weird error)
test_raiserror2 - usually doesnt work
** dumping results:
'1'
'1'
2 rows (-1: [Microsoft][ODBC SQL Server Driver]Function sequence error
(SQL-HY010)(DBD: st_fetch/SQLFetch err=-1))
errstr: [Microsoft][ODBC SQL Server Driver]Function sequence error
(SQL-HY010)(DBD: st_fetch/SQLFetch err=-1)
dropped
The error I expected is a raiserror in the sproc (sproc code below).
Is the telling me that I am executing something wrong via the DBI? Or
that my sproc has an issue (it runs well in the SQL 2000 Query
Analyzer).
I also tried adding a block of code to test for more_results, guessing
at how to do it. Code snippet below. The results were the same as
listed below in my first post.
#if ( $sth->more_results )
#{
# while ( @row_ary = $sth->fetchrow_array )
# {
# if ( $DBI::errstr )
# {
# print "err: $DBI::errstr \n";
# }
# else
# {
# print "**row: @row_ary \n";
# }
# }
#}
Thanks for any help,
Louise Mitchell

Try checking your second $sth for more_results. It may be affecting the
outcome.
