Counting the max length of string
Hi all,
I have a flat file of 1000 rows. I want to check the length of the 5th column. The one having the longest length , I want to set it as DEFINED PARAMETER.
So later I can check others with that particular number only.
Any ideas ??

alzabo::create::columndefinition
Alzabo::Create::ColumnDefinition(3pm) User Contributed Perl Documentation Alzabo::Create::ColumnDefinition(3pm)
NAME
Alzabo::Create::ColumnDefinition - Column definition object for schema creation
SYNOPSIS
use Alzabo::Create::ColumnDefinition;
DESCRIPTION
This object holds information on a column that might need to be shared with another column. The reason this class exists is that if a col-
umn is a key in two or more tables, then some of the information related to that column should change automatically in multiple places
whenever it changes at all. Right now this is only type ('VARCHAR', 'NUMBER', etc) and length/precision information. This object also has
an 'owner', which is the column which created it.
INHERITS FROM
"Alzabo::ColumnDefinition"
Note: all relevant documentation from the superclass has been merged into this document.
METHODS
new
This method takes the following parameters:
* owner => "Alzabo::Create::ColumnDefinition" object
* type => $type
It returns a new "Alzabo::Create::ColumnDefinition" object.
alter
See the "Alzabo::Column->alter()" method for details.
type
Returns the object's type as a string.
set_type ($string)
Sets the object's type.
Throws: "Alzabo::Exception::Params", "Alzabo::Exception::RDBMSRules"
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.
set_length
This method takes the following parameters:
* length => $length
* precision => $precision (optional)
Sets the column's length and precision. The precision parameter is optional (though some column types may require it if the length is
set).
Throws: "Alzabo::Exception::Params", "Alzabo::Exception::RDBMSRules"
owner
Returns the "Alzabo::Create::Column" object that owns this definitions (the column that created it).
