Variable Size Problem

Hello Everyone,

I am currently working with a DB2 (ver 8.1) table (Newly Created) and I am running a basic DB2 Select query into a variable. The field and it's size are VARCHAR(20). Since I need to pass the variable through some java I have noticed that when the results come back from the query there are extra spaces. Even if I use the RTRIM or LTRIM I still receive the spaces.

Is there a way to set a variable lenght before the results of a query are passed to it?

I would like to do the following,

Code:
variable1=`db2 -xn "length(rtrim(field1)) from Database"`
if (( variable1 == 16 ))
then
set $variable2 lenght to 16
fi
variable2=`db2 -xn "select LTRIM(RTRIM(field1)) from Database"`

Then I can pass $variable2 through the java.

I know it doesn't make much sense but it's what I need, hopefully.

thanks in advance...........Smilie

DateTime::Format::DB2(3pm)				User Contributed Perl Documentation				DateTime::Format::DB2(3pm)

NAME
DateTime::Format::DB2 - Parse and format DB2 dates and times SYNOPSIS
use DateTime::Format::DB2; my $dt = DateTime::Format::DB2->parse_timestamp( '2003-01-16-23.12.01.300000' ); # 2003-01-16-23.12.01.300000 DateTime::Format::DB2->format_timestamp($dt); DESCRIPTION
This module understands the formats used by DB2 for its DATE, TIME, and TIMESTAMP data types. It can be used to parse these formats in order to create DateTime objects, and it can take a DateTime object and produce a string representing it in the DB2 format. METHODS
This class offers the following methods. All of the parsing methods set the returned DateTime object's time zone to the floating time zone, because DB2 does not provide time zone information. * parse_time($string) * parse_date($string) * parse_timestamp($string) Given a value of the appropriate type, this method will return a new "DateTime" object. The time zone for this object will always be the floating time zone, because by DB2 stores the local datetime, not UTC. If given an improperly formatted string, this method may die. * format_date($datetime) * format_time($datetime) * format_timestamp($datetime) Given a "DateTime" object, this methods returns an appropriately formatted string. SUPPORT
Support for this module is provided via the datetime@perl.org email list. See http://lists.perl.org/ for more details. AUTHOR
