How to call an Oracle stored procedure in Perl?

To call an Oracle stored procedure using Perl, you can connect to the Oracle database using the DBI module and execute the stored procedure using the prepare and execute methods.

Below is an example code:

use DBI;

my $dsn = 'DBI:Oracle:host=HOSTNAME;sid=SID';
my $username = 'USERNAME';
my $password = 'PASSWORD';

# 连接到Oracle数据库
my $dbh = DBI->connect($dsn, $username, $password) or die "无法连接到数据库: $DBI::errstr";

# 定义存储过程的调用语句
my $sql = 'BEGIN your_procedure_name(:param1, :param2); END;';

# 准备执行存储过程
my $sth = $dbh->prepare($sql) or die "无法准备存储过程: $DBI::errstr";

# 绑定存储过程的参数
my $param1 = 'value1';
my $param2 = 'value2';
$sth->bind_param(':param1', $param1);
$sth->bind_param(':param2', $param2);

# 执行存储过程
$sth->execute() or die "无法执行存储过程: $DBI::errstr";

# 关闭数据库连接
$dbh->disconnect();

Please update the hostname, username, password, stored procedure name, and parameters in the sample code according to the actual situation.
