How to get a numeric value from Oracle to UNIX variable without spaces?

Hi,

I am using the below code to get a numeric value from oracle to unix variable:
Code:
BD_RC_CNT=`sqlplus -s ${WMD_DM_CONNECT} <<EOF
set heading off
set pagesize 0
Select count(*) 
from wmd_bad_data 
where proc_id = ${PROC_ID} 
and file_id = ${FILE_ID} 
and file_dt = to_date(${DATADATE},'yyyymmdd');
exit
EOF`

I issued echo command and output is below:
Code:
$ echo $BD_RC_CNT
6

How ever when i tried to find the length of the variable it shows 3 instead of 1:

$ echo `expr length "$BD_RC_CNT"`
3

Can somebody please help in removing the extra characters ?
Thanks in advance!Smilie

Hi
try this: mind the spaces: "read|space|BD_RC_CNT|space|<|space|<( etc..."
Code:
read BD_RC_CNT < <(sqlplus -s ${WMD_DM_CONNECT} <<EOF
set heading off
set pagesize 0
Select count(*) 
from wmd_bad_data 
where proc_id = ${PROC_ID} 
and file_id = ${FILE_ID} 
and file_dt = to_date(${DATADATE},'yyyymmdd');
exit
EOF)

Check whether you have tab in BD_RC_CNT
Code:
echo "$BD_RC_CNT"

Thanks, Both the solutions worked perfectly. And yes when i issued the command echo "$BD_RC_CNT" it showed as below
Code:
$ echo "$BD_RC_CNT"
         6

these seem to be some spaces then 6. may be 2 space then 6.

Thanks again for the help.Smilie

It might be single tab, space and 6. You can check that using cat
Code:
echo "$BD_RC_CNT" | cat -vet
