NAME
MySQL::Diff - Generates a database upgrade instruction set SYNOPSIS
use MySQL::Diff; my $md = MySQL::Diff->new( %options ); my $db1 = $md->register_db($ARGV[0], 1); my $db2 = $md->register_db($ARGV[1], 2); my $diffs = $md->diff(); DESCRIPTION
Generates the SQL instructions required to upgrade the first database to match the second. METHODS
Constructor new( %options ) Instantiate the objects, providing the command line options for database access and process requirements. Public Methods Fuller documentation will appear here in time :) o register_db($name,$inx) Reference the database, and setup a connection. The name can be an already existing 'MySQL::Diff::Database' database object. The index can be '1' or '2', and refers both to the order of the diff, and to the host, port, username and password arguments that have been supplied. o db1() o db2() Return the first and second databases registered via "register_db()". o diff() Performs the diff, returning a string containing the commands needed to change the schema of the first database into that of the second.
