=head1 NAME

SQL::Translator::Schema::Procedure - SQL::Translator procedure object

=head1 SYNOPSIS

  use SQL::Translator::Schema::Procedure;
  my $procedure  = SQL::Translator::Schema::Procedure->new(
      name       => 'foo',
      sql        => 'CREATE PROC foo AS SELECT * FROM bar',
      parameters => 'foo,bar',
      owner      => 'nomar',
      comments   => 'blah blah blah',
      schema     => $schema,
  );

=head1 DESCRIPTION

C is a class for dealing with
stored procedures (and possibly other pieces of nameable SQL code?).

=head2 new

Object constructor.

  my $schema = SQL::Translator::Schema::Procedure->new;

=cut

=head2 parameters

Gets and set the parameters of the stored procedure.

  $procedure->parameters('id');
  $procedure->parameters('id', 'name');
  $procedure->parameters( 'id, name' );
  $procedure->parameters( [ 'id', 'name' ] );
  $procedure->parameters( qw[ id name ] );

  my @parameters = $procedure->parameters;

=cut

with ListAttr parameters => ( uniq => 1 );

=head2 name

Get or set the procedure's name.

  $procedure->name('foo');
  my $name = $procedure->name;

=cut

has name => ( is => 'rw', default => quote_sub(q{ '' }) );

=head2 sql

Get or set the procedure's SQL.

  $procedure->sql('select * from foo');
  my $sql = $procedure->sql;

=cut

has sql => ( is => 'rw', default => quote_sub(q{ '' }) );

=head2 order

Get or set the order of the procedure.

  $procedure->order( 3 );
  my $order = $procedure->order;

=cut

has order => ( is => 'rw' );


=head2 owner

Get or set the owner of the procedure.

  $procedure->owner('nomar');
  my $sql = $procedure->owner;

=cut

has owner => ( is => 'rw', default => quote_sub(q{ '' }) );

=head2 comments

Get or set the comments on a procedure.

  $procedure->comments('foo');
  $procedure->comments('bar');
  print join( ', ', $procedure->comments ); # prints "foo, bar"

=cut

has comments => (
    is => 'rw',

=head2 schema

Get or set the procedures's schema object.

  $procedure->schema( $schema );
  my $schema = $procedure->schema;

=cut

has schema => ( is => 'rw', isa => schema_obj('Schema'), weak_ref => 1 );

around schema => \&ex2err;

=head2 equals

Determines if this procedure is the same as another

  my $isIdentical = $procedure1->equals( $procedure2 );

=cut
