Alzabo::Table - Table objects

  use Alzabo::Table;

  my $t = $schema->table('foo');

  foreach $pk ($t->primary_keys)
  {
     print $pk->name;
  }

Objects in this class represent tables. They contain foreign key, index, and column objects.

Returns the CWAlzabo::Schema object to which this table belongs.

Returns the name of the table.

Returns the CWAlzabo::Column object that matches the name given.

An CWAlzabo::Exception::Params exception is throws if the table does not contain the column.

If no arguments are given, returns a list of all CWAlzabo::Column objects in the schema, or in a scalar context the number of such tables. If one or more arguments are given, returns a list of table objects with those names, in the same order given.

An CWAlzabo::Exception::Params exception is throws if the table does not contain one or more of the specified columns.

Returns a voolean value indicating whether the column exists in the table.

In array context, return an ordered list of column objects that make up the primary key for the table. In scalar context, it returns the first element of that list.

The number of columns in the table's primary key. Returns a boolean value indicating whether the column given is part of the table's primary key.

This method is really only needed if you're not sure that the column belongs to the table. Otherwise just call the CWAlzabo::Column->is_primary_key method on the column object.

A table's attributes are strings describing the table (for example, valid attributes in MySQL are thing like TYPE = INNODB.

Returns a list of strings.

This method can be used to test whether or not a table has a particular attribute. By default, the check is case-insensitive.

* case_sensitive => 0 or 1 (defaults to 0)

Returns a boolean value indicating whether the table has this particular attribute.

Thie method takes two parameters:

It returns a list of CWAlzabo::ForeignKey objects from the given column to the given table, if they exist. In scalar context, it returns the first item in the list. There is no guarantee as to what the first item will be.

An CWAlzabo::Exception::Params exception is throws if the table does not contain the specified column. Returns a list of all the CWAlzabo::ForeignKey objects to the given table. In scalar context, it returns the first item in the list. There is no guarantee as to what the first item will be. Returns a list of all the CWAlzabo::ForeignKey objects that the given column is a part of, if any. In scalar context, it returns the first item in the list. There is no guarantee as to what the first item will be.

An CWAlzabo::Exception::Params exception is throws if the table does not contain the specified column.

Returns a list of all the CWAlzabo::ForeignKey objects for this table. In scalar context, it returns the first item in the list. There is no guarantee as to what the first item will be.

This method expects an index id as returned by the CWAlzabo::Index->id method as its parameter.

The CWAlzabo::Index object matching this id, if it exists in the table.

An CWAlzabo::Exception::Params exception is throws if the table does not contain the specified index.

This method expects an index id as returned by the CWAlzabo::Index->id method as its parameter.

Returns a boolean indicating whether the table has an index with the same id.

Returns all the CWAlzabo::Index objects for the table.

Returns the comment associated with the table object, if any.
