NAME

Fey::Column - Represents a column

SYNOPSIS

  my $column = Fey::Column->new( name              => 'user_id',
                                 type              => 'integer',
                                 is_auto_increment => 1,
                               );

DESCRIPTION

This class represents a column in a table.

METHODS

This class provides the following methods:

Fey::Column->new()

This method constructs a new Fey::Column object. It takes the following parameters:

name - required
The name of the column.
type - required
The type of the column. This should be a string. Do not include modifiers like length or precision.
generic_type - optional
This should be one of the following types:
- text
- blob
- integer
- float
- date
- datetime
- time
- boolean
- other
This indicate a generic type for the column, which is intended to allow for a common description of column types across different DBMS platforms.

If this parameter is not specified, then the constructor code will attempt to determine a reasonable value, defaulting to "other" if necessary.
length - optional
The length of the column. This must be a positive integer.
precision - optional
The precision of the column, for float-type columns. This must be an integer >= 0.
is_auto_increment - defaults to 0
This indicates whether or not the column is auto-incremented.
is_nullable - defaults to 0
A boolean indicating whether the column is nullab.e
default - optional
This must be either a scalar (including undef) or a Fey::Literal object. If a scalar is provided, it is turned into a Fey::Literal object via Fey::Literal->new_from_scalar().
