alzabo::column
Alzabo::Column(3pm) User Contributed Perl Documentation Alzabo::Column(3pm)
NAME
Alzabo::Column - Column objects
SYNOPSIS
use Alzabo::Column;
foreach my $c ($table->columns)
{
print $c->name;
}
DESCRIPTION
This object represents a column. It holds data specific to a column.
METHODS
table
Returns the table object to which this column belongs.
name
Returns the column's name as a string.
nullable
Returns a boolean value indicating whether or not NULLs are allowed in this column.
attributes
A column's attributes are strings describing the column (for example, valid attributes in MySQL are 'UNSIGNED' or 'ZEROFILL'.
This method returns a list of strings of such strings.
has_attribute
This method can be used to test whether or not a column has a particular attribute. By default, the check is case-insensitive.
It takes the following parameters:
* attribute => $attribute
* case_sensitive => 0 or 1 (defaults to 0)
It returns a boolean value indicating whether or not the column has this particular attribute.
type
Returns the column's type as a string.
sequenced
The meaning of a sequenced column varies from one RDBMS to another. In those with sequences, it means that a sequence is created and that
values for this column will be drawn from it for inserts into this table. In databases without sequences, the nearest analog for a
sequence is used (in MySQL the column is given the AUTO_INCREMENT attribute, in Sybase the identity attribute).
In general, this only has meaning for the primary key column of a table with a single column primary key. Setting the column as sequenced
means its value never has to be provided to when calling "Alzabo::Runtime::Table->insert".
Returns a boolean value indicating whether or not this column is sequenced.
default
Returns the default value of the column as a string, or undef if there is no default.
default_is_raw
Returns true if the default is intended to be provided to the DBMS as-is, without quoting, fore example "NOW()" or "current_timestamp".
length
Returns the length attribute of the column, or undef if there is none.
precision
Returns the precision attribute of the column, or undef if there is none.
is_primary_key
Returns a boolean value indicating whether or not this column is part of its table's primary key.
is_numeric
Returns a boolean value indicating whether the column is a numeric type column.
is_integer
Returns a boolean value indicating whether the column is a numeric type column.
is_floating_point
Returns a boolean value indicating whether the column is a numeric type column.
is_character
Returns a boolean value indicating whether the column is a character type column.
This is true only for any columns which are defined to hold text data, regardless of size.
is_date
Returns a boolean value indicating whether the column is a date type column.
is_datetime
Returns a boolean value indicating whether the column is a datetime type column.
is_time
Returns a boolean value indicating whether the column is a time type column.
is_time_interval
Returns a boolean value indicating whether the column is a time interval type column.
is_blob
Returns a boolean value indicating whether the column is a blob column.
This is true for any columns defined to hold binary data, regardless of size.
generic_type
This methods returns one of the following strings:
integer
floating_point
character
date
datetime
time
blob
unknown
definition
The definition object is very rarely of interest. Use the "type()" method if you are only interested in the column's type.
This methods returns the "Alzabo::ColumnDefinition" object which holds this column's type information.
comment
Returns the comment associated with the column object, if any.
