Autodia::Handler::SQL (3pm)

Autodia::Handler::SQL parses files into a Diagram Object, which all handlers use. The role of the handler is to parse through the file extracting information such as table names, field names, relationships and keys.

\s-1SQL\s0 is registered in the Autodia.pm module, which contains a hash of language names and the name of their respective language - in this case:

%language_handlers = { .. , sql => \*(L"Autodia::Handler::SQL\*(R", .. };

use Autodia::Handler::SQL;

my $handler = Autodia::Handler::SQL->New(\%Config); This creates a new handler using the Configuration hash to provide rules selected at the command line.

$handler->Parse(filename); # where filename includes full or relative path.

This parses the named file and returns 1 if successful or 0 if the file could not be opened.

$handler->output();

This outputs the Dia \s-1XML\s0 file according to the rules in the %Config hash passed at initialisation of the object. It also allows you to output \s-1VCG\s0, Dot or images rendered through GraphViz and \s-1VCG\s0.
