Append date to sql*plus spool (log) file in shell script

SQL*Plus version : 11.2.0.4
OS : Oracle Linux 6.5

SQL*Plus is a client application to connect to oracle database. The log file for this tool is generated via spool command as shown below.

I am trying to append date ( $dateString ) to spool file as shown below.

Code:
$ cat test2.sh
#!/bin/bash

dateString=`date +%d-%b-%Y_%H%M%S`

sqlplus scott/tiger@10.82.16.214:1521/ORCL<<EOF

set time on timing on

spool /home/appusr/scripts/'$dateString'_batch.log

select sysdate from dual;

spool off

EOF
exit

But the log file generated has single quote around the date part as shown below. How can I get rid of this ?

Code:
$ ls -l
total 8
-rw-rw-r-- 1 appusr appusr 360 Mar 30 18:35 '30-Mar-2017_183552'_batch.log
-rwxr-xr-x 1 appusr appusr 224 Mar 30 18:35 test2.sh

I tried escaping the single quotes using \ character. But, still the same issue.

Code:
spool /home/appusr/scripts/\'$dateString\'_batch.log

What happens if you just drop the single quotes from the "here document"?

Hi Rudic,
Already tried the following (no single quotes). In this case, logfile is not generated at all !

Code:
 spool /home/appusr/scripts/$dateString_batchtest3.log

Tried double quotes too ( "$dateString"_batchtest3.log )
# 4  
Did you tried
Code:
spool /home/appusr/scripts/${dateString}_batchtest3.log
