I am facing a strange situation and do not have a clue of why this is happenning. Any help will be really appreciated.
Here's the code which works: 
my $h_sql1 = $db_inv->prepare_cached( "select items from item_a where 
+item_code = ? and item_stock = 8" ) or die $DBI::errstr;

$h_sql1->execute( "A0001" );

After this I fetch the rows and get 1 row as result (which is what I should).
Then I changed this sql to following: 
my $h_sql1 = $db_inv->prepare_cached( "select items from item_a where 
+item_code = ? and item_stock = ?" ) or die $DBI::errstr;

$h_sql1->execute( "A0001", 8 );

This does not returns any rows. I have checked it with tracelevel set to 1, 2, and 3.
Seems like the binding is done correctly but the oracle database simply does not returns a row in the second sql (where I have 2 placeholders).
I've tried all different combinations with bind_param, etc and nothing seems to work.
As long as there is only 1 placeholder (? or even :var1 ) it works. The moment I add a second placeholder, there are no rows returned.
Can anyone help here?
Regards
