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 Alzabo::Schema object to which this table belongs.
Alzabo::Schema
Returns the name of the table.
Returns the Alzabo::Column object that matches the name given.
Alzabo::Column
An Alzabo::Exception::Params exception is throws if the table does not contain the column.
Alzabo::Exception::Params
If no arguments are given, returns a list of all Alzabo::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 Alzabo::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 Alzabo::Column->is_primary_key method on the column object.
Alzabo::Column->is_primary_key
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.
attribute => $attribute
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:
column => Alzabo::Column object
table => Alzabo::Table object
Alzabo::Table
It returns a list of Alzabo::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.
Alzabo::ForeignKey
An Alzabo::Exception::Params exception is throws if the table does not contain the specified column.
Returns a list of all the Alzabo::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 Alzabo::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.
Returns a list of all the Alzabo::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 Alzabo::Index->id method as its parameter.
Alzabo::Index->id
The Alzabo::Index object matching this id, if it exists in the table.
Alzabo::Index
An Alzabo::Exception::Params exception is throws if the table does not contain the specified index.
Returns a boolean indicating whether the table has an index with the same id.
Returns all the Alzabo::Index objects for the table.
Returns the comment associated with the table object, if any.
