Fey::Table::Alias(3)

NAME
Fey::Table::Alias - Represents an alias for a table

VERSION
version 0.44

SYNOPSIS
  my $alias = $user_table->alias();

  my $alias = $user_table->alias( alias_name => 'User2' );

DESCRIPTION
This class represents an alias for a table. Table aliases allow you to join the same table more than once in a query, which makes certain types of queries simpler to express.

METHODS
This class provides the following methods:

  Fey::Table::Alias->new()
This method constructs a new "Fey::Table::Alias" object. It takes the following parameters:

•   table - required

    This is the "Fey::Table" object which we are aliasing.

•   alias_name - optional

    This should be a valid table name for your DBMS. If not provided, a unique name is automatically created.

  $alias->table()
Returns the "Fey::Table" object for which this object is an alias.

  $alias->alias_name()
Returns the name for this alias.

  $alias->name()

  $alias->schema()
These methods work like the corresponding methods in "Fey::Table". The "name()" method returns the real table name.

  $alias->column($name)

  $alias->columns()

  $alias->columns(@names)

  $alias->primary_key()
These methods work like the corresponding methods in "Fey::Table". However, the columns they return will return the alias object when "$column->table()" is called.

  $alias->is_alias()
Always returns true.

  $alias->sql_with_alias()

  $table->sql_for_select_clause()
Returns the appropriate SQL snippet for the alias.

  $alias->id()
Returns a unique string identifying the alias.

ROLES
This class does the Fey::Role::TableLike and Fey::Role::Named roles.
