Hi all Iam facing an issue in the Linux shell script, TFN is fetching as NULL. Can someone help regarding the issue will be helpful


TFN=`sqlplus -s $LOGNAME1/$PASSWORD1@connstr << EOF > ${LogFileName}

Is redirecting the sqlplus output to your logfile and the command had no output (it’s gone to the log file) so TFN is empty.

Remove the > ${LogFileName} to TFN gets the value of the query and then echo $FN >> ${LogFileName} if you really want the query results in the log.
