CUT command not giving correct result inside loop

Hi,

i have a source file and have 3 columns and separated by "|" .i want to split this 3 columns in different variable.When i am executing this values indivisually giving correct result but when the same execute inside a for loop,it's giving issues.

Src file(jjj.txt)
-------
Code:
TAB_DAY|(((date_part('year',TAB_DAY.PROCESS_DATE) * 10000) + (date_part('month', TAB_DAY.PROCESS_DATE) * 100)) + date_part('day', TAB_DAY.PROCESS_DATE))|180
TAB_WEEK|((date_part('year',TAB_WEEK.PROCESS_DATE) * 100) + date_part('week', TAB_WEEK.PROCESS_DATE))|35
TAB_MONTH|((date_part('year',TAB_MONTH.PROCESS_DATE) * 100) + date_part('month', TAB_MONTH.PROCESS_DATE))|180

Without Loop
-------------
Code:
cat $jjj.txt|cut -d"|" -f1
TAB_DAY
TAB_WEEK
TAB_MONTH
cat $jjj.txt|cut -d"|" -f2
(((date_part('year', TAB_DAY.PROCESS_DATE) * 10000) + (date_part('month', TAB_DAY.PROCESS_DATE) * 100)) + date_part('day', TAB_DAY.PROCESS_DATE))
((date_part('year', TAB_WEEK.PROCESS_DATE) * 100) + date_part('week', TAB_WEEK.PROCESS_DATE))
((date_part('year', TAB_MONTH.PROCESS_DATE) * 100) + date_part('month', TAB_MONTH.PROCESS_DATE))
cat $jjj.txt|cut -d"|" -f3
180
35
180

But the same in for loop not working ....giving biased result

Code:
file=/home/dbadmin/jjj.txt
for i in `cat /home/dbadmin/jjj.txt`
do
echo $i
s=`echo $i|tr -s ' '|cut -d"|" -f1`
q=`echo $i|tr -s ' ' |cut -d"|" -f2`
x=`echo $i |tr -s ' '|cut -d"|" -f3`
 
echo $s
echo $q
echo $x

CUT(1)							    BSD General Commands Manual 						    CUT(1)

NAME
cut -- select portions of each line of a file SYNOPSIS
cut -b list [-n] [file ...] cut -c list [file ...] cut -f list [-d delim] [-s] [file ...] DESCRIPTION
The cut utility selects portions of each line (as specified by list) from each file and writes them to the standard output. If the file argument is a single dash ('-') or no file arguments were specified, lines are read from the standard input. The items specified by list can be in terms of column position or in terms of fields delimited by a special character. Column numbering starts from 1. list is a comma or whitespace separated set of increasing numbers and/or number ranges. Number ranges consist of a number, a dash (-), and a second number and select the fields or columns from the first number to the second, inclusive. Numbers or number ranges may be preceded by a dash, which selects all fields or columns from 1 to the first number. Numbers or number ranges may be followed by a dash, which selects all fields or columns from the last number to the end of the line. Numbers and number ranges may be repeated, overlapping, and in any order. It is not an error to select fields or columns not present in the input line. The options are as follows: -b list The list specifies byte positions. -c list The list specifies character positions. -d string Use the first character of string as the field delimiter character. The default is the <TAB> character. -f list The list specifies fields, separated by the field delimiter character. The selected fields are output, separated by the field delimiter character. -n Do not split multi-byte characters. -s Suppresses lines with no field delimiter characters. Unless specified, lines with no delimiters are passed through unmodified. EXIT STATUS
cut exits 0 on success, 1 if an error occurred. SEE ALSO
paste(1) STANDARDS
The cut utility conforms to IEEE Std 1003.2-1992 (``POSIX.2''). BSD
