<A name=pgfId=1030540>[/url]$sth = $dbh->prepare("SELECT truc, machin FROM table WHERE bidule=?");

$sth->execute( $bidule );

while ( @ligne = $sth->fetchrow_array ) {print "@lignen";}

Hello, I've a  DBI-perl-program  with 4 distinct sql requests.

Always the same are called many time in each loop.

Do you think it's a good idea to create many $sth, like this

$sth1 = $dbh->prepare("SELECT truc, machin FROM table1 WHERE bidule=?");

$sth2 = $dbh->prepare("SELECT truc, machin FROM table2 WHERE bidule=?");

$sth3 = $dbh->prepare("SELECT truc, machin FROM table WHERE bidule=?");

and called them when it's necessary.  That mean the object will stay open

during long long time, and I won't destroy $sth1 before using $sth2

Does it affects the Oracle Database to keep during few hours this kind of objects

Thank you.
