The answer is what I'm finding!
So happy, and thinks a lot!

But I haven't another question on MySQL Procedure being call:

If Procedure have a parameter act as inout, the above skill can't work.
I use the follow sample, but no work.

#!/usr/bin/perl

#
# PROCEDURE `TEST_COUNT_PLUS`
#
# CREATE DEFINER=`root`@`localhost` PROCEDURE `TEST_COUNT_PLUS`(INOUT 
+NUMBER1 INTEGER)
# BEGIN
   # DECLARE NUMBER2 INTEGER
   # DEFAULT (SELECT COUNT(*) FROM PLAYERS);
   # SET NUMBER1 = NUMBER2 + NUMBER1;
# END$$

use DBI;

my $dbh = DBI->connect('dbi:mysql:tennis','BOOKSQL','BOOKSQLPW') or di
+e "Connection Error: $DBI::errstr\n"; 
$dbh->do("set @hit_count=10");  # error, don't work!!!

my $sql = 'call TEST_COUNT_PLUS(@hit_count)';
my $sth = $dbh->prepare($sql);
$sth->execute || die $DBI::errstr;
$sth->finish; 

# Now get the output variable
@result = $dbh->selectrow_array('SELECT @hit_count') || die $DBI::errs
+tr;
print "result=", $result[0], "\n";

$dbh->disconnect;

How can I input the INOUT parameter value to the procedure?
