NAME

DBIx::ParseError::MySQL - Error parser for MySQL

VERSION

version v1.0.2

SYNOPSIS

    use DBIx::ParseError::MySQL;

    eval {
        my $result = $dbh->do('SELECT 1');
    };
    if ($@) {
        if (DBIx::ParseError::MySQL->new($@)->is_transient) { $dbh->reconnect }
        else                                                { die; }
    }

DESCRIPTION

This module is a database error categorizer, specifically for MySQL. This module is also compatible with Galera's WSREP errors.

ATTRIBUTES

orig_error

Returns the original, untouched error object or string.

error_string

Returns the stringified version of the error.

error_type

Returns a string that describes the type of error. These can be one of the following:

    lock             Lock errors, like a lock wait timeout or deadlock
    connection       Connection/packet failures, disconnections
    shutdown         Errors that happen when a server is shutting down
    duplicate_value  Duplicate entry errors
    unknown          Any other error

is_transient

Returns a true value if the error is the type that is likely transient. For example, errors that recommend retrying transactions or connection failures. This check can be used to figure out if it's worth retrying a transaction.

This is merely a check for the following error types: lock connection shutdown.

CONSTRUCTORS

new

    my $parsed_error = DBIx::ParseError::MySQL->new($@);

Returns a DBIx::ParseError::MySQL object. Since the error is the only parameter, it can be passed by itself.

SEE ALSO

DBIx::Class::ParseError - A similar parser, but specifically tailored to DBIx::Class.
