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

LEARN ABOUT DEBIAN

datetime::format::db2

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.
