How to create and call mysql stored procedure in perl?

Hi,

I want to create MySQL stored procedure and call the stored procedure using perl.

I tried like this:

Code:
use DBI;
my $dbh = DBI->connect ("DBI:mysql:test",
                           "root", "ibab",
                           { RaiseError => 1, PrintError => 0});
$create_procedure = qq{
    CREATE PROCEDURE greeting()
	BEGIN
	select current_time() AS time;
	END
};
$dbh->do(qq{DROP PROCEDURE IF EXISTS greeting});
$dbh->do($create_procedure);
my $sth = $dbh->prepare(qq{CALL greeting()});
$sth->execute();

The procedure is getting created in Mysql but when i am trying to run i am getting this error.

Code:
C:\Perl\bin>perl try.pl
DBD::mysql::st execute failed: PROCEDURE test.greeting can't return a result set in the given context

I am not able to identify and debug what is this error?

Here is the result in MySQL.
Code:
mysql> SHOW CREATE PROCEDURE greeting\G
*************************** 1. row ***************************
       Procedure: greeting
        sql_mode: STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER
Create Procedure: CREATE DEFINER=`root`@`localhost` PROCEDURE `greeting`()
BEGIN
        select current_time() AS time;
        END
1 row in set (0.01 sec)


mysql> call greeting();
+----------+
| time     |
+----------+
| 14:51:11 |
+----------+
1 row in set (0.03 sec)

I am not able to get the above output. The output should be current time displayed.

Code:
+----------+
| time     |
+----------+
| 14:51:11 |
+----------+

How can i do it in perl?

Code:
MySQL Version
mysql> select version();
+---------------------+
| version()           |
+---------------------+
| 5.0.27-community-nt |
+---------------------+
1 row in set (0.00 sec)

Perl Version:perl, v5.8.8

Help may be very much appreciated.

Regards
Vanitha

NAME
DBIx::Class::Storage::DBI::mysql - Storage::DBI class implementing MySQL specifics SYNOPSIS
Storage::DBI autodetects the underlying MySQL database, and re-blesses the $storage object into this class. my $schema = MyApp::Schema->connect( $dsn, $user, $pass, { on_connect_call => 'set_strict_mode' } ); DESCRIPTION
This class implements MySQL specific bits of DBIx::Class::Storage::DBI, like AutoIncrement column support and savepoints. Also it augments the SQL maker to support the MySQL-specific "STRAIGHT_JOIN" join type, which you can use by specifying "join_type => 'straight'" in the relationship attributes It also provides a one-stop on-connect macro "set_strict_mode" which sets session variables such that MySQL behaves more predictably as far as the SQL standard is concerned. STORAGE OPTIONS
set_strict_mode Enables session-wide strict options upon connecting. Equivalent to: ->connect ( ... , { on_connect_do => [ q|SET SQL_MODE = CONCAT('ANSI,TRADITIONAL,ONLY_FULL_GROUP_BY,', @@sql_mode)|, q|SET SQL_AUTO_IS_NULL = 0|, ] }); AUTHORS
