oracle行计入shell脚本变量

Question

I want to get count of oracle table into shell variable so I can compare to row count in csv file and make sure record counts match. When I execute below script I get: COUNT(*) ---------- 100000 I would like to just get: 100000

What are good approaches?

VAR="$(sqlplus -S usr/pw@//host:1521/db <<ENDOFSQL
select count(*) from table;
exit;
ENDOFSQL)"  
echo $VAR

Try this,

VAR="$(sqlplus -S usr/pw@//host:1521/db <<ENDOFSQL
set head off
select count(*) from table;
exit;
ENDOFSQL)"  
echo $VAR
