What is transactions and AutoCommit in Perl?

In Perl, transactions refer to a sequence of operations performed as a single unit of work. This means that either all operations in the transaction are executed successfully, or none of them are applied, ensuring data integrity. Transactions are commonly used when interacting with databases to manage changes to data efficiently.

AutoCommit is a feature in Perl's database interaction that determines whether a transaction is automatically committed to the database after each execution of a statement. When AutoCommit is on, every individual statement gets executed and committed. However, when it's off, you must explicitly commit your changes to the database.

Here's a basic example demonstrating how to use transactions and AutoCommit with DBI module in Perl:

use DBI; my $dbh = DBI->connect("DBI:mysql:database_name", "username", "password", { RaiseError => 1, AutoCommit => 0 }); eval { $dbh->do("INSERT INTO users (name, age) VALUES ('Alice', 30)"); $dbh->do("INSERT INTO users (name, age) VALUES ('Bob', 25)"); $dbh->commit; # Commit the transaction }; if ($@) { warn "Transaction failed: $@"; $dbh->rollback; # Rollback the transaction } $dbh->disconnect;
