Yes I want my output lines in mysql table to contain the lowest(first) and highest (last) value for a particular id_name and media value.
so as you mentioned I would like my table to contain entries like this :

| PSK_30s1189731L001 | -1 | 1 | 3 | 999 | 7285 | 9808 | c |

or should it be one of the input lines). If one of the input lines, does it matter which one?

>Does the order of the lines in the table in your output matter?
The order of lines dont matter in my required mysql table

I missed the' | ' ! Error from my part.

@Don :
For the question :Why doesn't your sample output contain the 2nd header line from your sample input?

I am not sure whether you are asking for the small sample I provided or the input and final output.

Eithercase.

Considering the small snippet sample:

given input :
Code:
 
id_name | model | mode | media| first | end | id | level |
+--------------------+-------+---------+-----+-------+-------+--------+--------+
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 14684 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 14838 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15236 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15423 | 6255 | q |
| PSK_30s1207681L002 | 1 | 1 | N | 14026 | 15627 | 6255 | q |

I take PSK_30s1207681L002 and media =5 and look for the smallest first entry and highest end value .

Hence in case of PSK_30s1207681L002 & media =5 I will have only one entry
Code:
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15423 | 6255 | q |

The 2nd line in sample input is contained within the ranges
Code:
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 14838 | 6255 | q |

i e 14026 and 14838 falls within range 14026 and 15423

So I dont need that entry in my table.

dbix::searchbuilder::handle::mysql

DBIx::SearchBuilder::Handle::mysql(3pm) 		User Contributed Perl Documentation		   DBIx::SearchBuilder::Handle::mysql(3pm)

NAME

	 DBIx::SearchBuilder::Handle::mysql - A mysql specific Handle object

SYNOPSIS

DESCRIPTION

       This module provides a subclass of DBIx::SearchBuilder::Handle that compensates for some of the idiosyncrasies of MySQL.

METHODS

   Insert
       Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted.

       If the insert succeeds, returns the id of the insert, otherwise, returns a Class::ReturnValue object with the error reported.

   SimpleUpdateFromSelect
       Customization of "SimpleUpdateFromSelect" in DBIx::SearchBuilder::Handle.  Mysql doesn't support update with subqueries when those fetch
       data from the table that is updated.

   DatabaseVersion
       Returns the mysql version, trimming off any -foo identifier

   CaseSensitive
       Returns undef, since mysql's searches are not case sensitive by default

   SimpleDateTimeFunctions
       Returns hash reference with specific date time functions of this database for "DateTimeFunction" in DBIx::SearchBuilder::Handle.

   ConvertTimezoneFunction
       Custom implementation of "ConvertTimezoneFunction" in DBIx::SearchBuilder::Handle.

       Use the following query to get list of timezones:

	   SELECT Name FROM mysql.time_zone_name;

       Read docs about keeping timezone data up to date:
