( #3333=superdoc: print w/replies, xml ) Need Help??
Here's a little test program I use to replicate the issue:
#!/usr/bin/perl -w use strict; use DBI; my $dbh=DBI->connect('zzz','zzz','zzz'); while(1){ my $sth=$dbh->prepare_cached('select count(*) from EXAMPLE'); $sth->execute(); my @r=$sth->fetchrow(); print "$r[0]\n"; $sth->finish(); sleep 10; } $dbh->disconnect();
When I do the work to EXAMPLE that invalidates the statment handle, my example code returns the following:
DBD::Oracle::st execute failed: ORA-00942: table or view does not exist (DBD ERROR: OCIStmtExecute)

DBD::Oracle::st execute failed: ORA-01003: no statement parsed (DBD ERROR: OCIStmtExecute)
What I'd like is for prepare_cached to recover gracefully from these types of intermittent hiccups. Any ideas?
