[Sqlrelay-discussion] DBD::SQLRelay bind_param_inout problem (0.41), and minimal patch.

[hiroaki k. <hk...@cp...>]

Hello.

I found following script returns undefined value in bound inout
variable: $id

...
my $sth = $dbh->prepare(<<END);
insert into nr_test(nr_dir) values(?)
returning nr_test.rowid into ?
END

my $place;
$sth->bind_param(++$place, $dir);
$sth->bind_param_inout(++$place, \ my $id, 64);
...

Note: Above worked fine on sqlrelay-0.37.1.

After some stracing, I finally found  DBD::SQLRelay::st::execute calls
$cursor->clearBinds *before* $cursor->getOutputBindString.
Attached patch will fix this problem.
